    Betulinic Acid induced tumor killing - Franziska B. Mullauer - AMC Amsterdam et.al.; The Netherlands © (2011) The author.


    Abstract - New therapies employing novel mechanisms to induce tumor cell death are needed with plants playing a crucial role as a source for potential anti-cancer compounds. One highly promising class of natural compounds are the triterpenoids with betulinic acid (BetA) as the most prominent representative. In vitro studies have identified this agent as potently effective against a wide variety of cancer cells, also those derived from therapy resistant and refractory tumors, whereas it has been found relatively non-toxic for healthy cells. In vivo preclinically applied BetA showed some remarkable anti-cancer effects and a complete absence of systemic toxicity in rodents. BetA also cooperated with other therapies to induce tumor cell death and several potent derivatives have been discovered. Its anti-tumor activity has been related to its direct effects on the mitochondria.

    Betulinic Acid for Cancer Treatment and Prevention - Simone Fulda - International Journal of Molecular Sciences © (2008) The author.


    Abstract - Betulinic acid is a natural product with a range of biological effects, for example potent antitumor activity. This anticancer property is linked to its ability to induce apoptotic cell death in cancer cells by triggering the mitochondrial pathway of apoptosis. In contrast to the cytotoxicity of betulinic acid against a variety of cancer types, normal cells and tissue are relatively resistant to betulinic acid, pointing to a therapeutic window. Compounds that exert a direct action on mitochondria present promising experimental cancer therapeutics, since they may trigger cell death under circumstances in which standard chemotherapeutics fail. Thus, mitochondrion-targeted agents such as betulinic acid hold great promise as a novel therapeutic strategy in the treatment of human cancers.

    Betulinic Acid Inhibits Prostate Cancer Growth through Inhibition of Specificity Protein Transcription Factors - Sudhakar Chintharlapalli et.al. - American Association for Cancer Research © (2007) The authors.


    Abstract - Betulinic acid is a pentacyclic triterpene natural product initially identified as a melanoma-specific cytotoxic agent that exhibits low toxicity in animal models. Subsequent studies show that betulinic acid induces apoptosis and antiangiogenic responses in tumors derived from multiple tissues; however, the underlying mechanism of action is unknown. Using LNCaP prostate cancer cells as a model, we now show that betulinic acid decreases expression of vascular endothelial growth (VEGF) and the antiapoptotic protein survivin. The mecha- nism of these betulinic acid–induced antiangiogenic and proapoptotic responses in both LNCaP cells and in tumors is due to activation of selective proteasome-dependent degra- dation of the transcription factors specificity protein 1 (Sp1), Sp3, and Sp4, which regulate VEGF and survivin expression. Thus, betulinic acid acts as a novel anticancer agent through targeted degradation of Sp proteins that are highly overexpressed in tumors.

    Polysaccharide Immunomodulators as Therapeutic Agents - ARTHUR O. TZIANABOS - Harvard Medical School, Boston, USA © (2000) The author.


    Abstract - Recently, many advances have been made toward understanding host immune responses to infectious diseases. Novel cell surface and soluble signaling molecules produced by cells of the immune system have been discovered that regulate host responses to microorganisms. It is now widely appreciated that these molecules interact in a concerted fashion to maintain a balance that governs an appropriate response to infectious organisms. Investigators have focused on discovering com- pounds that positively or negatively modulate the biologic re- sponse of immune cells and enhance the host's ability to resist microbial infection. Several classes of these compounds, such as proteins, peptides, lipopolysaccharides, glycoproteins, and lipid derivatives, have all been characterized as molecules that have potent effects on the host immune system. Peptides such as cytokines and chemokines are well-known examples of such molecules. While polysaccharides have long been believed to have benign biologic properties, certain polymers have recently been shown to act as potent immunomodulating agents. This review will focus on polysaccharides that exhibit this biologic activity and their potential for clinical use.

    Immuunmodulatie door voedsel: rol bij allergie? - H.J. Wichers - Nederlands Tijdschrift voor Allergie en Astma, The Netherlands © (2010) The author.


    Samenvatting - De laatste decennia is een afname waarneembaar van infectieziekten, tezamen met een toename van immuungerelateerde ziekten, waarvan over de oorzaken en eventuele samen- hang nog slechts hypotheses bestaan. Het functioneren van het immuunsysteem is onder andere afhankelijk van dieet en voedsel. Er is een aantal voedingsproducten in de handel met claims met betrekking tot preventie van allergische reacties, zoals pro- en prebiotica en eiwithydrolysaten. Het onderzoek naar het nut en de mogelijkheden van immuunmodu- latoir voedsel met betrekking tot allergieën is volop gaande: naast probiotica wordt onder andere onderzoek verricht aan polysacchariden en bepaalde eiwitten. Al deze 'hot topics' in het onderzoek hebben gemeen dat ze microbieel van oorsprong zijn, en zowel de aangeboren als de Th1-gemedieerde afweer lijken te stimuleren. Wellicht duidt dit erop dat een immuunsysteem dat enigszins uit balans is, in zekere mate 'heropgevoed' kan worden.

    Samenvatting - In onze voeding en leefomgeving komen zeer veel verschillende eiwitten voor, waarvan sommige in staat zijn allergische sensibilisatie te veroorzaken en bij verdere blootstelling een allergische reactie kunnen geven. De eigenschappen die een eiwit tot een allergeen maken zijn echter niet bekend. Hierdoor is op voorhand de allergeniciteit van een voedseleiwit niet te voorspellen. Daarnaast bestaat er een zeer grote mate van heterogeniteit van allergenen op basis van genetische, posttranslationele en structurele verschillen. De voedselmatrix waarin allergenen zich bevinden, kan de mate van allergeniciteit moduleren. Over deze laatste eigenschap van voeding is slechts zeer weinig bekend.

    Abstract - Arden Andersen is more than a fixture at almost every Acres U.S.A. Conference. He is a medical doctor with more than a passing interest in the real medicine of Hippocrates — "Let food be your medicine." He is also a progressive agronomist. In both roles he makes the connection between health in the soil and health in plants, animals and human beings. As a consultant, he works with growers worldwide. It is hard to say whether he is more at home as a teacher, field consultant or health practitioner. Effective in all areas, his greatest impact may well be via the students he has trained to comprehend and use the information con- tained in this interview and in the books he has written.

    Medicinal mushrooms - their therapeutic properties and current medical usage with special emphasis on cancer treatments. - John E. Smith et.al. - Cancer Research UK © (2000) The authors.


    Abstract - Many of the currently available anti-cancer agents are derived form natural products, for instance paclitaxel (Taxol), and camptothecin (Hycamtin) amongst many others. In 2000 Professor Gordon McVie, Director-General of the Cancer Research Campaign (now Cancer Research UK) and Professor John Smith of University of Strathclyde met in Glasgow to discuss the role of medicinal mushrooms in the treatment of cancer. The CRC had become aware that these natural products were being used extensively in the Far East as nutriceuticals (dietary supplements) and as a source for the generation of pharmaceutical-grade medicines to treat a wide variety of diseases, including cancer. The substantial range of medicinal mushroom species from which different bioactive compounds can be derived suggested that the humble mushroom could be a source of novel anti-cancer agents. This monograph is a comprehensive overview of this subject from the technology of cultivation, extraction and chemistry of medicinal mushroom bioactive compounds to the clinical evidence that suggests an important therapeutic role in cancer, and other major diseases.

    Immunomodulation by dietary mushroom compounds - H.J. Wichers, H.J. Savelkoul, et.al. - Wageningen University and Research Centre, Wageningen, The Netherlands © (2004) The authors.


    Abstract - Mushrooms are long used food supplements that display profound immunomodulatory activities, due to the presence of both polysaccharides (ß-D-glucans) and proteins (FIP). These compounds work either alone or in concert and both target different aspects of the immune system. While ß-glucans are considered to bind to innate receptors and activate innate cells (dendritic cells and monocytes/macrophages), immunomodulatory proteins will be taken up, processed and presented on antigen-presenting cells to CD4+ Th cells in the context of MHC class II molecules. The outcome is different and results in the activa- tion of both innate and antigen-specific adaptive immune reactivity. The combined presence in a whole extracts is therefore expected to be of more use than either active compound alone. Here we will describe some of the immunomodulatory activities present in such extracts from edible mushrooms.

    Medicinal mushroom modulators of molecular targets as cancer therapeutics - Solomon P. Wasser et.al. - Applied Microbiology & Biotechnology (2005) 67: 453–468 © (2005) Springer-Verlag.


    Abstract - Empirical approaches to discover anticancer drugs and cancer treatments have made limited progress in the past several decades in finding a cure for cancer. The expanded knowledge of the molecular basis of tumorigenesis and metastasis, together with the inherently vast structural diversity of natural compounds found in mushrooms, provided unique opportunities for discovering new drugs that rationally target the abnormal molecular and biochemical signals leading to cancer. This review focuses on mushroom low-molecular-weight secondary metabolites targeting processes such as apoptosis, angiogenesis, metastasis, cell cycle regulation, and signal transduction cascades. Also discussed in this review are high-molecular-weight polysaccharides or polysaccharide–protein complexes from mushrooms that appear to enhance innate and cell-mediated immune responses, exhibit antitumor activities in animals and humans, and demonstrate the anticancer properties of selenium com- pounds accumulated in mushrooms.

    Immunobiology of Mushrooms - Andrea T. Borchers et.al. - Society for Experimental Biology and Medicine © (2008) The authors.


    Abstract - There has been enormous interest in the biologic activity of mushrooms and innumerable claims have been made that mushrooms have beneficial effects on immune function with subsequent implications for inhibition of tumor growth. The majority of these observations are anecdotal and often lack standardization. However, there remains considerable data on both in vitro and in vivo effects that reflect on the potential of mushroom compounds to influence human immunity. A number of these effects are beneficial but, unfortunately, many responses are still characterized based on phenomenology and there is more speculation than substance. With respect to tumor biology, although many neoplastic lesions are immunogenic, tumor antigens frequently are self antigens and induce tolerance and many patients with cancer exhibit suppressed immune responses, including defective antigen presentation. Therefore, if and when mushroom extracts are effective, they more likely function as a result of improved antigen presentation by dendritic cells than by a direct cytopathic effect. In this review we attempt to place these data in perspective, with a particular focus on dendritic cell populations and the ability of mushroom extracts to modulate immunity. There is, at present, no scientific basis for the use of either mushrooms or mushroom extracts in the treatment of human patients but there is significant potential for rigorous research to understand the potential of mushrooms in human disease and thence to focus on appropriate clinical trials to demonstrate effectiveness and/ or potential toxicity.

  •  • ›  Medicinal Values of Mushrooms

    Medicinal Values of Mushrooms - Shu-Ting Chang, Philip G. Miles - CRC Press, 2nd edition © (2004) The authors.


    Abstract - Mushrooms have long been considered to have medicinal value. The early herbalists were more interested in the medicinal properties of mushrooms than in their basic value as a source of food. Recently, Western society has placed a great emphasis on plants, herbs, and foods as sources of these health enhancers. About 3.5 billion people worldwide, well over half of the world's population, rely on plant-based medicines and dietary supplements for their primary health care.
    Recently, the products of medicinal mushrooms have demonstrated to enhance the immune system and promote the natural defense system. They are also good for patients who have received treatment with radiotherapy or chemotherapy, as they may help to reduce the side effects from such therapies.

    These include :
    • increasing the number of leucocytes in the blood, and enhancing the immune functions (it has been known that chemo- therapy treatment can markedly deplete the number of platelets in the blood and put patients at risk of excessive bruising, internal bleeding, brain hemorrhage, and sometimes death);
    • increasing and improving appetite;
    • reducing pain;
    • anti-emetic properties;
    • stopping hair loss;
    • inducing tumor regression;
    • potential antioxidant and genoprotective properties, and
    • general health-improving effects.

    Exactly how these products work is still a matter of conjecture, but numerous trials (both laboratory and human) have shown, again and again, that they are effective in complementing conventional medicines in fighting diseases.
    People unfamiliar with the field may ask, "If those mushrooms have such beneficial effects, can chemists isolate the active com- ponent so that it can be marketed as a drug?" If the answer is "yes," the main focus is on a single active component of the mushroom, e.g., lentinan, which is close to drug standard, and on certain diseases, e.g., cancers or heart diseases only. The products are prescription drugs. If the answer is "no," then the main focus is on a group of compounds, and on people's quality of life. The products are dietary supplements and are not single active components.
    The research achievements in medicinal mushrooms during the last two decades give the impression, and the confidence, that medicinal mushrooms have much to offer to the health-care system for humans in the 21st century. In cases where modern medicines may not provide a complete remedy, complementation by mushroom nutriceuticals may augment the success of the treatment. Prevention of diseases is beneficial to everyone and deserves the same attention that is given to the curing of diseases.

    Anti-inflammatory and Immunomodulating Properties of Fungal Metabolites - Cristina Lull et.al. - Agrotechnology and Food Innovations, Wageningen University and Research Center, The Netherlands. © (2004) The authors.


    Abstract - We discuss current information on the ability of extracts and isolated metabolites from mushrooms to modulate immune responses. This can result in a more enhanced innate and acquired disease resistance. The major immunomodulating effects of these active substances derived from mushrooms include mitogenicity and activation of immune effector cells, such as lymphocytes, macrophages, and natural killer cells, resulting in the production of cytokines, including interleukins (ILs), tumor necrosis factor alpha (TNF)-alpha, and interferon gamma (INF)-gamma. In particular, the ability of selective mushroom extracts to modulate the differentiation capacity of CD4(+) T cells to mature into T(H)1 and/or T(H)2 subsets will be discussed. As a consequence these extracts will have profound effects in particular diseases, like chronic autoimmune T(H)1-mediated or allergic T(H)2-mediated diseases. Immunosuppressive effects by mushroom components have also been observed. The therapeutic effects of mushrooms, such as anticancer activity, suppression of autoimmune diseases, and allergy have been associated with their immunomodulating effects. However, further studies are needed to determine the molecular mechanisms of the immunomodulating effects of mushrooms metabolites both individually and in complex mixtures, for example, extracts.

    Abstract - Edible and medicinal mushrooms (macrofungi) not only can convert the huge lignocellulosic biomass* waste into human food, but -- most remarkably -- can produce notable mycopharmaceuticals, myconutriceuticals and mycocosmeceuticals. Pharmaceutical substances with potent and unique health-enhancing properties were isolated recently from medicinal mushrooms and distributed worldwide. In Japan, China, Russia, and Korea, several different polysaccharide antitumor drugs have been developed from the fruiting bodies, mycelia, and culture media of various medicinal mushrooms.The Japan Cancer Association proved that A. blazei is effective against Ehrlich's ascites carcinoma, sigmoid colon cancer, ovarian cancer, breast cancer, lung cancer, and liver cancer, as well as against solid cancers.

    Compounds from Wild Mushrooms with Antitumor Potential - Isabel C.F.R. Ferreira, et.al. - publisher unknown - Portugal © (2008) The authors.


    Abstract - For thousands of years medicine and natural products have been closely linked through the use of traditional medicines and natural poisons. Mushrooms have an established history of use in traditional oriental medicine, where most medicinal mushroom prepara- tions are regarded as a tonic, that is, they have beneficial health effects without known negative side-effects and can be moderately used on a regular basis without harm. Mushrooms comprise a vast and yet largely untapped source of powerful new pharmaceutical products. In particular, and most importantly for modern medicine, they represent an unlimited source of compounds which are modulators of tumour cell growth. Furthermore, they may have potential as functional foods and sources of novel molecules. We will review the com- pounds with antitumor potential identified so far in mushrooms, including low-molecular-weight (LMW, e.g. quinones, cerebrosides, isoflavones, catechols, amines, triacylglycerols, sesquiterpenes, steroids, organic germanium and selenium) and high-molecular-weight compounds (HMW, e.g. homo and heteroglucans, glycans, glycoproteins, glycopeptides, proteoglycans, proteins and RNA-protein complexes).

    Abstract - Anti-tumor activity of mushroom fruit bodies and mycelial extracts evaluated using different cancer cell lines. These polysaccharide extracts showed potent antitumor activity against sarcoma 180, mammary adenocarcinoma 755, leukemia L-1210 and a host of other tumors. The antitumor activity was mainly due to indirect host mediated immunotherapeutic effect. These studies are still in progress in many laboratories and the role of the polysaccharides as immunopotentiators is especially under intense debate. The purpose of the present review is to summarize the available information in this area and to indicate the present status of the research.

    Advances in Mushroom Research in the Last Decade - Leifa Fan et.al. - Food Technol. Biotechnol. 44 (3) 303–311 (2006) © (2006) The authors.


    Abstract - There has been a lot of progress in mushroom science and biotechnology in the last decade. The optimisation of PFGE separation of fungal chromosomes allowed the study of the molecular karyotype of mushrooms and the assignment of genes to chromosomes. There are 115 genes encoded from different species of mushrooms. Cross breeding continues to be the principal method, but it is accompanied by the analyses of RAPD or RFLPs methods. The genetic makers are used and introduced into commercial large hybrids via introgression breeding. The complex traits such as yield, resistance to disease and quality characteristics, and quantitative traits more than one quantitative trait locus (QTL) are found and used in practice. The transformants or transgenic mutant strains were obtained by Agrobacterium system or particle bombardment. At least 651 species representing 182 genera of hetero- and homobasidiomycetes mushrooms were researched containing anti-tumor or immuno-stimulating polysaccharides. Ergosterol in the lipid fraction was identified as one of the most active constituents. New sesquiterpenoid hydroquinones, steroids, oxalic acid, triterpenes, water-soluble lignins, sulfated polysaccharides, protein-bound polysaccharides are researched intensively as antimicrobial or antiviral agents. Many small molecular mass compounds exhibit cytotoxic activities, such as illudins, leaianafulvene, triterpenes (ganoderic acids), acetoxyscirpenediol, ergosterol peroxide, sterols. There are many other compounds or activities found in the mushrooms, such as anti-oxidative, hypoglycemic action, anti-inflammatory effect, hepato-protective compounds, psychoactive compounds and activities.

    Abstract - The widespread occurrence of biological activities within the fungal kingdom is now widely accepted. Since ancient times the so called mushrooms meaning Basidiomycota have been used for medicinal purpose. All major human body functions were considered to benefit from fungi intake. These positive effects include prophylactic as well as curative actions. Historically, Oriental countries first recognised mushrooms as an important source of medicines. Recently, Occidental research starts to really consider this almost untapped source of therapeutic drugs. Indeed, discovering new major medics is becoming a great challenge. The aim of the present review is to outline past and current major therapeutic interest and pharmacology of medicinal mushrooms, and their applications in human health care. Indeed, metabolites from Basidiomycota demonstrate verified pharmacological activity in major diseases such as chronic inflammation, oxidation associated pathologies, diabetes, infections (HIV, fungi, bacteria), immune system disorder and cancer.

    Mushrooms as a functional food mediator in preventing and ameliorating diabetes - Kamal Perera, et.al. - Functional Foods in Health and Disease 2011; 4:161-171


    Abstract - Diabetes is a major health problem predisposing to markedly increased complications. Despite the numerous preventative strategies and armories of medication, the management of diabetes remains grossly unsatisfactory. Diabetes is emerging as a pandemic. Therefore it is important to identify novel nutraceuticals or drugs for curing or preventing diabetes, which have fewer side effects. The present paper reviewed scientific information on mushrooms with regards to its anti-diabetic active compounds and/or pharmacological test results, which are commonly used as functional foods and ingredients used in the traditional medical system and which have demonstrated experimental or/and clinical anti-diabetic effectiveness. These functional foods might have a big potential for the prevention or cure of diabetes more than in other plant species. However, still scientific or clinical studies are not sufficient for hypoglycemic effect for mushrooms use as ‘official’ drug. Therefore, it is proposed that a close attention be paid to carry out further research of functional mushrooms for preventive and curative measures for diabetes and its complications.

    Effect of Agaricus blazei Murill on the Pulmonary Tissue of Animals with Streptozotocin-Induced Diabetes - Fábio Cangeri Di Naso, et.al. - Experimental Diabetes Research Volume 2010, Article ID 543926 © (2010) Hindawi Publishing Corporation


    Abstract - The present study was designed to evaluate the oxidative stress as well as the therapeutic effect of Agaricus blazei Muril (A. Blazei) in rats with streptozotocin-induced diabetes. We used 25 Wistar rats, and DM was induced by injecting streptozotocin (70 mg/Kg i.p.). Agaricus blazei Muril was administered daily starting 40 days after disease onset. A. Blazei was tested as an aqueous extract for its phytochemical composition, and its antioxidant activity in vitro was also evaluated. Lipoperoxidation (LPO), and superoxide dismutase (SOD), catalase, and glutathione peroxidase activities were measured in the pulmonary tissue, as well as the presence of inducible nitric oxide synthase (iNOS), through immunohistochemistry. An anatomopathologic study was also performed. Phytochemical screening of A. Blazei detected the presence of alkaloids and saponins. The extract exhibited a significant antioxidant activity in the DPPH-scavenging and the hipoxanthine/xanthine oxidase assays. Pulmonary LPO increased in diabetic animals (0.43 ± 0.09; P < .001) as compared to the control group (0.18 ± 0.02), followed by a reduction in the A. Blazei-treated group (0.33 ± 0.04; P < .05). iNOS was found increased in the lung in diabetic rats and reduced in the A. Blazei-treated group. The pulmonary tissue in diabetic rats showed oxidative alterations related to the streptozotocin treatment. The A. Blazei treatment effectively reduced the oxidative stress and contributed to tissue recovery.

    Abstract - The Basidiomycete fungus Agaricus blazei Murill has traditionally been used as a health food for the prevention of cancer, diabetes, hyperlipidemia, arteriosclerosis and chronic hepatitis. In the present study, we examined the antitumor activities of various substances isolated from the lipid fraction of A. blazei. Tumor growth was retarded by the oral administration of the lipid fraction extracted from A. blazei with a chloroform/methanol mixture in sarcoma 180-bearing mice. The substance with the antitumor activity in the lipid fraction was isolated via silica gel column chromatography, eluted with an acetonitrile/methanol (3:2) mixture and identified as ergosterol by direct comparison of the (1)H NMR and mass spectrometry spectral data of an authentic sample. The oral administration of ergosterol to sarcoma 180-bearing mice significantly reduced tumor growth at doses of 400 and 800 mg/kg administered for 20 d without side effects, such as the decreases in body, epididymal adipose tissue, thymus, and spleen weights and leukocyte numbers induced by cancer chemotherapy drugs. Ergosterol had no cytotoxicity against tumor cells. To clarify the antitumor activity of ergosterol, we examined the effects of ergosterol on tumor-induced angiogenesis using two in vivo models. Intraperitoneal administration of ergosterol at doses of 5, 10 and 20 mg/kg for 5 consecutive d inhibited the neovascularization induced by Lewis lung carcinoma cell-packed chambers, suggesting that either ergosterol or its metabolites may be involved in the inhibition of tumor-induced neovascularization. Therefore, we further examined the inhibitory effects of ergosterol on Matrigel-induced neovascularization. Female C57BL/6 mice were subcutaneously inoculated with Matrigel containing acidic fibroblast growth factor and heparin with or without ergosterol. Ergosterol inhibited the Matrigel-induced neovascularization, suggesting that ergosterol directly inhibits Matrigel-induced neovascularization. From these results, it seems likely that the antitumor activity of ergosterol might be due to direct inhibition of angiogenesis induced by solid tumors. This is the first report of ergosterol as an antiangiogenic substance.

    An extract of the medicinal mushroom Agaricus blazei Murill can protect against allergy - Linda K Ellertsen, Geir Hetland - Department of Environmental Immunology, Norwegian Institute of Public Health, Oslo, Norway - Department of Immunology and Transfusion Medicine, Oslo University Hospital, Ulleval, Oslo, Norway © (2009) The authors.


    Abstract - Agaricus blazei Murill (AbM) is an edible Brazilian mushroom that has been used in traditional medicine for a range of diseases. It has been shown to have anti-infection and anti-tumor properties in the mouse, which are due to induction of Th1 responses. On the other hand, IgE- mediated allergy is induced by a Th2 response. Objective: Since according to the Th1/Th2 paradigm an increased Th1 response may promote a reduced Th2 response, the aim was to examine whether AbM had anti-allergy effects. Methods: A mouse model for allergy was employed, in which the mice were immunized s.c. with the model allergen ovalbumin (OVA). Additionally, the animals were given a mushroom extract, AndoSanTM, mainly (82%) containing AbM, but also Hericium erinaceum (15%) and Grifola frondosa (3%), or PBS p.o. either a day before or 19 days after the immunization. The mice were sacrificed on day 26, and anti-OVA IgE (Th2 response) and IgG2a (Th1 response) antibodies were examined in serum and Th1, Th2 and Treg cytokines in spleen cells cultures. Results: It was found that the AndoSanTM extract both when given either before or after OVA immunization reduced the levels of anti-OVA IgE, but not IgG2a, in the mice. There was a tendency to reduced Th2 relative to Th1 cytokine levels in the AndoSanTM groups. Conclusion: This particular AbM extract may both prevent allergy development and be used as a therapeutical substance against established allergy.

    Abstract - In South America, natural products with unknown drug effects are used as folk remedies and for preventive medicine. Among South American natural products, we directed our attention to Agaricus, Propolis and Paffia, which have been known as medicinal plants, and examined the mechanisms by which these substances affect antioxidant activity, anti-tumor activity and immunoresponse. Concuding, the results strongly suggest that Agaricus, Propolis and Paffia enhance original functions of macrophages and NK (Natural Killer) cells, and as a result, secondarily enhances the immune reaction and suppresses tumor growth.

    Abstract - White button mushroom, the cream type (Agaricus bisporus) and five different A. blazei (syn. A. subrufescens) cultivars were cultivated on Phase II. mushroom compost under identical conditions in the study. We compared the yields of strains and the phenol content was measured by spectrophotometer, while total antioxidant capacity of the extracts was determined by FRAP method. Our results revealed a tight correspondence between total antioxidant capacity and total phenol content of samples. We concluded that differences can be found between mushroom species, moreover between varieties in accumulation of secondary metabolites. The measured parameters differed in stipes and caps. Based on these results it is possible to select A. blazei cultivars in other point of view, underline the fact that medicinal products and pharmaceuticals prepared from this mushroom species can be very distinct.

    Abstract - Inonotus obliquus (persoon) Pilat (Chaga, in Russia, kabanoanatake in Japan) is a fungus having been used as a folk medicine in Russia and said to have many health beneficial functions such as immune modulating and anti-cancer activities. In the present study, the antioxidant activity of hot water extract (decoction) of Chaga was precisely compared with those of other medicinal fungi (Agaricus blazei Mycelia, Ganoderma lucidum and Phellinus linteus) showing Chaga had the strongest antioxidant activity among fungi examined in terms of both superoxide and hydroxyl radicals scavenging activities. Further determination of the antioxidant potential of isolated fruiting body (brown part) and Sclerotium (black part) revealed the 80% MeOH extract of fruiting body had the highest potential as high as that of Chaga decoction. Finally, seven antioxidant components were isolated and purified from the 80% MeOH extract of Chaga fruiting body, and their chemical structures were determined as small phenolics as follows: 4-hydroxy-3,5-dimethoxy benzoic acid 2-hydroxy-1-hydroxymethyl ethyl ester (BAEE), protocatechic acid (PCA), caffeic acid (CA), 3,4-dihybenzaladehyde (DB), 2,5-dihydroxyterephtalic acid (DTA), syringic acid (SA) and 3,4-dihydroxybenzalacetone (DBL). Notably, BAEE was assigned as the new compound firstly identified from the natural source in the present study.

    Identification of Inonotus obliquus (Chaga) and Analysis of Antioxidation and Antitumor Activities of Polysaccharides - Yana Song et.al. - © (2008) The authors.


    Abstract Inonotus obliquus, a wild wood-decay fungus which grows on birch trees in cool climates, has a variety of biological activities that the scientific community is paying more and more attention to. However, the research work is moving at a snail's pace. The methods of strain identification and the hypha microstructure have not been reported. We isolated one strain of filamentous molds from fruit body which was collected from birch wood on Changbai Mountain, cultivated mycelia on an inclined plane, and examined its micro morphology based on macroscopic examination. The strain was identified as I. obliquus by sequencing its ITS (internal transcribed spacer) domain. We subsequently investigated some of the mycelium polysaccharides' biological activities. The strain used in this study as the producers of anti oxidation and anti- cancer polysaccharides was LNUF008. After fermentation in a 30-L fermenter, mycelia were obtained. The polysaccharides were extracted by transonic recirculation and ethanol precipitation. In order to identify the anti oxidation effect, we designed an assay to test the inhibition of endogenous and Fe2+-Cys-induced lipid peroxidation as well as ferrous sulfate/ascorbate (Fe2+-VC)-induced mitochondrial swelling. The MTT [3-(4,5-dimethylthiazol-2- yl)-2,5-diphenyltetrazolium bromide] method was used to study the anti proliferation activity of the polysaccharides on SMMC7721 hepatoma cells. The results indicate that I. obliquus polysaccharides exhibit high anti tumor and anti oxidation effects. The submerged culture method of growing I. obliquus will enable large-scale production of the polysaccharides.

    Sterol composition in field-grown and cultured mycelia of Inonotus Obliquus - Zheng Wei-fa, et.al. - Key laboratory for biotechnology on Medicinal plants, Xuzhou, China © 2006 the authors.


    Abstract - Sterols are one of the active classes of compounds in Inonotus obliquus for their effective therapy of many diseases. In field environment, this fungus accumulates large amount of sterols. In cultured mycelia, however, this class of compounds is less accumulated. For analyzing the factors responsible for differing sterol composition, the field-grown and cultured mycelia were extracted with 80% ethanol at room temperature and total sterols were prepared using silicon gel column chromatography followed by identification using either GC-MS or spectroscopic methods. The results suggested that the sterol composition in mycelia of the fungus can be diversified by supplementing substances inhibiting enzymatic process towards the synthesis of ergosterol. Harsh growth conditions in field environment (i. e. temperature variation, UV irradiation etc.) can delay the synthesis of ergosterol and hereby diversify the sterol composition in the mycelia of Inonotus obliquus.

    Antitumor Activity of Water Extract of a Mushroom, Inonotus obliquus, against HT-29 Human Colon Cancer Cells - Sung Hak Lee, et.al. - PHYTOTHERAPY RESEARCH © (2009) The authors.


    Abstract - In the current study, it was demonstrated that the hot water extract of I. obliquus (IOWE) exerts inhibitory activity against the proliferation of human colon cancer cells (HT-29). The inhibitory effect of IOWE on the growth of HT-29 cancer cells was evaluated by treating cells with IOWE at concentrations of 0.25, 0.5 and 1.0 mg/mL for 24 or 48 h. The IOWE inhibited cell growth in a dose-dependent manner, and this inhibition was accompanied by apoptotic cell death. The maximum inhibitory effect (56%) was observed when IOWE was treated at a concentration of 1.0 mg/mL for 48 h. The apoptotic effect of IOWE on HT-29 cells was also confirmed by flow cytometric analysis. In addition, the apoptotic cell percentage was closely associated with down-regulation of Bcl-2 and up-regulation of Bax and caspase-3. The results suggest that IOWE would be useful as an antitumor agent via the induction of apoptosis and inhibition of the growth of cancer cells through up-regulation of the expression of proapoptotic proteins and down-regulation of anti-apoptotic proteins.

    Abstract - The mushroom Inonotus obliquus (Fr.) Pilát (Hymenochaetaceae), has been widely used as a folk medicine in Russia, Poland and most of the Baltic countries. The purpose of this study was to elucidate the antioxidant capacities of Inonotus obliquus. Four extracts from the fungus were evaluated for antioxidant activity against the 1,1-diphenyl-2-picrylhydrazyl (DPPH), superoxide, and peroxyl radicals. The polyphenolic extract had a strong antioxidant activity, and the extract containing triterpenoids and steroids presented a relatively strong antioxidant effect. The polysaccharide extract, however, was inactive. The protective effects of these four extracts were assessed against hydrogen peroxide-induced oxidative stress using a human keratinocyte cell line, HaCaT. Our results show that the polyphenolic extract protected these cells against hydrogen peroxide-induced oxidative stress, while the polysaccharide, triterpenoid and steroid extracts were ineffective. Additionally, the remnant polyphenolic and low molecular weight polysaccharide extracts showed a weakly protective effect at a concentration of 50 􏰀g/ml. Our results indicate that Inonotus obliquus has the capacity to scavenge free radicals at concentrations higher than 5 􏰀g/ml and that the polyphenolic extract can protect cells against oxidative stress.

    Abstract - Inonotus obliquus is a mushroom commonly known as Chaga that is widely used in folk medicine in Siberia, North America, and North Europe. Here, we evaluated the antimutagenic and antioxidant capacities of subfractions of Inonotus obliquus extract. The ethyl acetate extract was separated by vacuum chromatography into three fractions, and the fraction bearing the highest antimutagenic activity was subsequently separated into four fractions by reversed phase (ODS-C18) column chromatography. The most antimutagenic fraction was then separated into two subfractions (subfractions 1 and 2) by normal phase silica gel column chromatography. Ames test analysis revealed that the subfractions were not mutagenic. At 50 􏰀g/plate, subfractions 1 and 2 strongly inhibited the mutagenesis induced in Salmonella typhimurium strain TA100 by the directly acting mutagen MNNG (0.4 􏰀g/plate) by 80.0% and 77.3%, respectively. They also inhibited 0.15 􏰀g/plate 4NQO-induced mutagenesis in TA98 and TA100 by 52.6–62.0%. The mutagenesis in TA98 induced by the indirectly acting mutagens Trp-P-1 (0.15 􏰀g/plate) and B(􏰁)P (10 􏰀g/plate) was reduced by 47.0–68.2% by the subfractions, while the mutagenesis in TA100 by Trp-P-1 and B(􏰁)P was reduced by 70.5–87.2%. Subfraction 1 was more inhibitory than subfraction 2 with regard to the mutagenic effects of 4NQO, Trp-P-1, and B(􏰁)P. Subfractions 1 and 2 also had a strong antioxidant activity against DPPH radicals and were identified by MS, 1H NMR and 13C NMR analyses as 3􏰂-hydroxy-lanosta-8, 24- dien-21-al and inotodiol, respectively. Thus, we show that the 3􏰂-hydroxy-lanosta-8, 24-dien-21-al and inotodiol components of Inonotus obliquus bear antimutagenic and antioxidative activities.

    Abstract - Extracts and fractions of Inonotus obliquus (Chaga in Russia) have been known to have various biological activities, including antimutagenic, anticancer, antioxidative, and immunostimulating effects. This study was performed to confirm anticancer effect of 10% superfine Chaga mushroom processed by nano-mill technology on C57BL/6 mice. Chaga parti- cles belonged in the size of 1 μm was about 40% after nanomill processing according to the volume distribution. As the result of subcutaneous injection of B16BL6 melanoma cells to the mice, the tumor volume (p⁄0.001) and tumor weight (p⁄0.01) was significantly decreased in the experimental (NCh) group as compared with control (C) group and the tumor growth inhibitory rate was 29.2%. On examination of survival rate after intraperitoneal injection of B16BL6 melanoma cells, the mean survival time per a mouse was 17.7 and 26.0 days in C and NCh group respectively. The survival rate of NCh group was 40% when that of C group was 0% at the 35th day. On the result of examination to confirm histological toxicity by Chaga superfine particles, both groups did not show any morphological and pathological changes in the small and large intestine under the light microscope. These results suggest that feeding of superfine Chaga produced by nano- mill technique has a tumor growth inhibitory effect in vivo.

    Phenolic compounds from Inonotus obliquus and their immune-stimulating effects - ZHENG Wei-Fa, et.al., - Mycosystema 27(4) p.574-581 © (2008) The author.


    Abstract - Phenolic compounds from field-grown Inonotus obliquus sclerotia (Chaga) consist mainly of hispidin analogs and melanins, and are thought to be the active constituents to treat several human diseases. In submerged cultures of the fungus, however, no information is currently available on the production of phenolic compounds and their corresponding pharmacological functions. In this study, phenolic compounds from Chaga and submerged cultures of the fungus were assayed for their composition and immune-stimulating effects. Phenolic compounds produced by I. obliquus in submerged cultures mostly consist of flavonoids, together with small amounts of hispidin analogs and melanins. This is quite contrary to the situation in Chaga, where flavonoids are determined as trace elements. Furthermore, phenolic compounds from Chaga show capacity about two-fold higher than those produced in submerged cultures in inhibiting cyclophosphamide-induced reduction of bodyweight, spleen index and viability of peripheral lymphocytes in test mice. Thus less production of hispidin analogs and melanins is likely to be responsible for less immune-stimulating effects in phenolic compounds from submerged cultures, and additional factors should be imposed during submerged cultures of I. obliquus to regulate biosynthesis of phenolic compounds directed to the composition similar to Chaga.

    The scientific rediscovery of an ancient Chinese herbal medicine- Cordyceps sinensis; part 2 - JIA-SHI ZHU, et.al. (29 pages)


    Abstract - Cordyceps sinensis (Berk.) Sacc., is a time-honored tonic food and herbal medicine in China, where recent research has shown that many of its traditional uses may be viewed from the basis of pharmacological activities. The ongoing exploration of C. sinensis in its wild form and cultured, fermented mycelial products derived from it, are reviewed from English and Chinese literature. Part II concludes the series with a review of C. sinensis in preclinical in vitro and in vivo studies, and open-label and double-blinded clinical trials on the respiratory, renal, hepatic, cardiovascular, immunologic, and nervous systems, and its effects on cancer, glucose metabolism, inflammatory conditions, and toxicological studies. In Part I, which appeared in autumn 1998, we discussed the effects of C. sinensis on antisenescence, endocrine and sexual functions, atherosclerosis, hyperlipidemia, and free radicals.

    Pharmacological Functions of Chinese Medicinal Fungus Cordyceps sinensis and Related Species - SHENG-YUAN WANG, et.al. (10 pages)


    Abstract - Cordyceps sinensis, an entomogenous fungus used in traditional Chinese medicine, exhibits very broad biological and pharmacological actions in hepatic, renal, cardiovascular, and immunologic systems as well as anticancer activity. Pharmacological functions of Cordyceps are primarily due to the bioactive polysaccharides, modified nucleosides, and cyclosporin-like metabolites produced by this fungus and related species. The beneficial effects on renal and hepatic function and immunomodulation-related antitumor activities are most promising and deserve great attention. Many previous studies used fruiting bodies, but recently an increasing number of studies have used cultured mycelia in investigations. It is difficult to determine if the same bioactive ingredients exist in fruiting bodies and cultured mycelia and contribute to the pharmacological actions reported in the literature. More mechanism-based, disease-oriented pharmacologi- cal studies are required to ensure clinical efficacy for particular diseases. Adjuvant therapy using C. sinensis for immune function distur- bances, cancer, and renal failure is possible if double-blind, randomized placebo-control clinical studies show the efficacy of this herb.

    Quality control of Cordyceps sinensis, a valued traditional Chinese medicine - S.P. Li et.al. (14 pages)


    Abstract - Cordyceps sinensis, a well-known and valued traditional Chinese medicine, is also called DongChongXiaCao (winter worm summer grass) in Chinese. It is commonly used to replenish the kidney and soothe the lung for the treatment of fatigue, night sweating, hyposexualities, hyperglycemia, hyperlipidemia, asthemia after severe illness, respiratory disease, renal dysfunction and renal failure, arrhythmias and other heart disease, and liver disease. As the rarity and upstanding curative effects of natural Cordyceps, several mycelial strains have been isolated from natural Cordyceps and manufactured in large quantities by fermentation technology, and they are commonly sold as health food products in Asia. In addition, some substitutes such as Cordyceps militaris also have been used and adulterants also confused the market. Therefore, quality control of C. sinensis and its products is very important to ensure their safety and efficacy. Herein, markers and analytical methods for quality control of Cordyceps were reviewed and discussed.

    Effects of a supplement designed to increase ATP levels on muscle strength, power output, and endurance - Trent J Herda et.al. (5 pages)


    Abstract
    Background: The present study examined the acute effects of a nutritional supplement intended to improve adenosine triphosphate (ATP) concentrations on vertical jump height, isometric strength of the leg extensors, leg extension endurance, and forearm flexion endurance.
    Methods: Twenty-four healthy men (mean age SD = 23 4 yrs, stature = 181 7 cm, and body mass = 82 12 kg) volunteered to complete a familiarization trial plus 2 randomly-ordered experimental trials separated by a 7-day washout period. Participants received either 6 (body mass < 91 kg) or 8 (body mass 91 kg) tablets of the treatment (TR; 625 mg of adenylpyrophosphoric acid and calcium pyruvate, 350.8 mg of cordyceps sinensis extract and yohimbine hydrochloride) or placebo (PL; 980 mg of microcrystalline cellulose) 1 hour prior to the following tests: countermovement vertical jump (CVJ), forearm flexion repetitions to exhaustion, isometric maximal voluntary contractions (MVCs) of the leg extensors, and a 50-repetition maximal concentric isokinetic leg extension endurance test.
    Results: There were no differences between the TR and PL trials for CVJ height (P > 0.05), isometric MVC peak torque (P > 0.05), maximal concentric isokinetic peak torque (P > 0.05), percent decline during the leg extension endurance tests (P > 0.05), or repetitions to exhaustion during the forearm flexion endurance tests (P > 0.05).
    Conclusion: These findings indicated no improvements in the measured variables as a result of ingesting this nutritional supplement. Future studies should examine whether chronic supplementation or a loading period is necessary to observe any ergogenic effects of this supplement.

    Genetic diversity of Ophiocordyceps sinensis, a medicinal fungus endemic to the Tibetan Plateau: Implications for its evolution and conservation - Yongjie Zhang et.al. (12 pages)


    Abstract
    Background: Ophiocordyceps sinensis (syn. Cordyceps sinensis), endemic to alpine regions on the Tibetan plateau, is one of the most valuable medicinal fungi in the world. Huge commercial demand has led to excessive harvest and a dramatic decline in its numbers. The diversity of terrains and climates on the Tibetan Plateau and the broad insect host range (more than 50 species in the family Hepialidae) may have resulted in substantial intraspecific genetic diversity for this fungus. The objective of this study was to evaluate the population distribution of O. sinensis from geographically diverse regions of the Tibetan Plateau based on nrDNA ITS and MAT1-2-1 gene sequences. Understanding of the genetic diversity and genesis of O. sinensis will provide important information for the evolution and conservation of this fungus.
    Results: Significant sequence variations in the ITS and MAT1-2-1 genes (27 and 23 informative sites, eight and seven haplotypes, respectively) were observed. Phylogenetic analysis based on ITS sequences, MAT1-2-1 sequences, or their combined data set, clustered isolates from northern regions in one clade (clade I), whereas isolates from southern regions were dispersed in all four clades (clade I-IV). Single-strand conformation polymorphism (SSCP) analyses of 2639 ITS clones from seven samples revealed 91 different SSCP patterns that were subsequently sequenced. ITS heterogeneity was found in XZ-LZ07-H1 (Nyingchi population), and 17 informative sites and five haplotypes were detected from 15 clones. The five haplotypes clustered into three clades (clade I, II, and IV).
    Conclusions: Significant genetic divergence in O. sinensis was observed and the genetic diversification was greater among southern isolates than that among northern isolates. The polymorphism of nrDNA ITS sequences suggested that O. sinensis spread from a center of origin (the Nyingchi District) to southern regions and subsequently to northern areas. These results suggest that southern populations are important reservoirs of genetic diversity and should be taken into account in conservation programs.

    Abstract - This study aimed to evaluate the ability of the health food supplement Cordyceps sinensis (CS) to ameliorate suppressive effects of chemotherapy on bone marrow function as a model for cancer treatment Mice were treated with Taxol (17 mg/kg body wt) one day before oral administration of a hot-water extract of CS (50 mg/kg daily) that was given daily for 3 weeks. White blood cell counts in peripheral blood of mice receiving Taxol were at 50% of normal levels on day 28 but had recovered completely in mice treated with CS. In vitro assays showed that CS enhanced the colony-forming ability of both granulocyte macrophage colony forming unit (GM-CFU) and osteogenic cells from bone marrow preparations and promoted the differentiation of bone marrow mesenchymal stromal cells into adipocytes, alkaline phosphatase–positive osteoblasts, and bone tissue. This result could be attributed to enhanced expression of Cbfa1 (core binding factor a) and BMP-2 (bone morphogenetic protein) with concurrent suppression of ODF (osteoclast differentiation factor/RANK [receptor activator of NF-κB]) ligand. In summary, CS enhances recovery of mice from leukopenia caused by Taxol treatment. It appears to do so by protecting both hematopoietic progenitor cells directly and the bone marrow stem cell niche through its effects on osteoblast differentiation.

    PSP in clinical cancer therapy - A brief overview of Phase I, II and III trials - Prof. Qing-yao Yang - Shanghai Teachers Academy, 2000 © (2000) The author.


    Abstract - Polysaccharide-peptide (PSP) is a protein bound polysaccharide isolated from the Cov-1 strain of Yunzhi and made from modern alcohol extraction techniques. Each capsule contains 0.34 grams of PSP. Experimental in-vitro and in-vivo studies have shown PSP inhibits the proliferation of cancer cells including P338 leukemia cells, S 180 cells, Ehrlich ascites, and stomach and lung cancer cells. It also inhibits the growth of some tumors such as the lymphatic tumor of human skin tissue cells. In addition, PSP affects the immune system of mice by stimulating the production of α-interferons, increasing the phagocytic index and metabolic rate of the reticuloendothilial system and by raising the HC 50 (median hemolytic dose), IgG and PFC (plaque forming cell) values. Human in-vivo experiments have also shown PSP can modulate the immune system by helping to prevent and partly eliminate the side effects of radiation and chemotherapeutic agents used by cancer patients.

    The Use of Mushroom Glucans and Proteoglycans in Cancer Treatment - Parris M. Kidd, PhD -


    Abstract - Immunoceuticals can be considered as substances having immunotherapeutic efficacy when taken orally. More than 50 mushroom species have yielded potential immunoceuticals that exhibit anticancer activity in vitro or in animal models and of these, six have been investigated in human cancers. All are non-toxic and very well tolerated. Lentinan and schizophyllan have little oral activity. Active Hexose Correlated Compound (AHCC) is poorly defined but has shown early clinical promise. Maitake D- Fraction has limited proof of clinical efficacy to date, but controlled research is underway. Two proteoglycans from Coriolus versicolor – PSK (Polysaccharide-K) and PSP (Polysaccharide-Peptide) – have demonstrated the most promise. In Japanese trials since 1970, PSK significantly extended survival at five years or beyond in cancers of the stomach, colon-rectum, esophagus, nasopharynx, and lung (non-small cell types), and in a HLA B40-positive breast cancer subset. PSP was subjected to Phase II and Phase III trials in China. In double-blind trials, PSP significantly extended five-year survival in esophageal cancer. PSP significantly improved quality of life, provided substantial pain relief, and enhanced immune status in 70-97 percent of patients with cancers of the stomach, esophagus, lung, ovary, and cervix. PSK and PSP boosted immune cell production, ameliorated chemotherapy symptoms, and enhanced tumor infiltration by dendritic and cytotoxic T-cells. Their extremely high tolerability, proven benefits to survival and quality of life, and compatibility with chemotherapy and radiation therapy makes them well suited for cancer management regimens.

    Chemopreventive Effect of PSP Through Targeting of Prostate Cancer Stem Cell-Like Population - Sze-Ue Luk et. al. - PLoS ONE May 2011 ◆ Volume6, Number5 ◆ 2011 ©2011 the authors.


    Abstract - Recent evidence suggested that prostate cancer stem/progenitor cells (CSC) are responsible for cancer initiation as well as disease progression. Unfortunately, conventional therapies are only effective in targeting the more differentiated cancer cells and spare the CSCs. Here, we report that PSP, an active component extracted from the mushroom Turkey tail (also known as Coriolus versicolor), is effective in targeting prostate CSCs. We found that treatment of the prostate cancer cell line PC-3 with PSP led to the down-regulation of CSC markers (CD133 and CD44) in a time and dose-dependent manner. Meanwhile, PSP treatment not only suppressed the ability of PC-3 cells to form prostaspheres under non-adherent culture conditions, but also inhibited their tumorigenicity in vivo, further proving that PSP can suppress prostate CSC properties. To investigate if the anti-CSC effect of PSP may lead to prostate cancer chemoprevention, transgenic mice (TgMAP) that spontaneously develop prostate tumors were orally fed with PSP for 20 weeks. Whereas 100% of the mice that fed with water only developed prostate tumors at the end of experiment, no tumors could be found in any of the mice fed with PSP, suggesting that PSP treatment can completely inhibit prostate tumor formation. Our results not only demonstrated the intriguing anti-CSC effect of PSP, but also revealed, for the first time, the surprising chemopreventive property of oral PSP consumption against prostate cancer.

    Clinical Implications of PSP in Oncology - T.F. Liu and W.C. Xue - Department of Radiation Oncology Cancer Hospital, Shanghai Medical University ◆ (1989) © the authors.


    Abstract - Up to now, the three main weapons against cancer have been surgery, radiotherapy and chemotherapy. Although these classical methods of treatment have given fairly good results in general, the results have yet to be improved, especially in late cases. Thus for many years, the search for a more effective means of anti-cancer treatment has been going on world-wide. An ideal drug would of course be one that could directly kill all the cancer cells without harming the normal tissues, and also without causing general toxicity. However, at present a more practical approach is to use drugs that would either enhance the biological effects of radiation or of cytotoxic agents, or strengthen the organism's immunological defenses. In recent years, several such drugs have been undergoing clinical trials, for example, Misonidazole, RS 2508, OK-432, PSK, etc. The drug that we shall talk about today is polysaccharide peptide, hereafter referred to as PSP.

    Coriolus versicolor - Detailed Scientific Review - MD Anderson Cancer center University of Texas © University of Texas


    Abstract - Coriolus versicolor was first recorded during the Ming Dynasty of China, and subsequently in a 1965 Japanese report of a patient with stomach cancer who benefited from drinking a tea, Saru-no-koshikake, that contained this mushroom. Subsequent laboratory and animal research identified the source of the tea's anti-tumor effects to be two polysaccharides. In 1989, two investigators at the U. S. National Cancer Institute (Jong and Donovick) published a review of antitumor and antiviral substances from fungi including Coriolus versicolor. This review noted seven studies and two U. S. patents issued for polysaccharides extracted from Coriolus versicolor. One extract was a polysaccharide-protein (proteoglycan) known as polysaccharide Kurcha (PSK or Krestin), and it had been found to be effective in the treatment of Ehrlich carcinoma and sarcoma 180 tumors in mice. Furthermore, PSK had not exhibited any of the cytotoxicity or other side effects commonly seen with conventional anticancer treatment. Subsequent laboratory and animal studies have further defined the antitumor, antimicrobial, antiviral and immune enhancing properties in both PSK and another protein-bound polysaccharide known as polysaccharide-protein complex (PSPC or PSP). Both substances are extracted by hot water from the mushroom's cultured mycelium.

    Abstract - In China, C. versicolor is named Yun Zhi (meaning "cloud-like mushroom"). C. versicolor is mainly used as an adjuvant in the treatment of cancer. The active principle derived from C. versicolor belongs to a new class of elements called biological response modifiers (BRM) which are defined as agents capable of stimulating the immune system and thereby, they express various therapeutic effects. The best know commercial polysaccharopeptide preparations of C. versicolor are polysaccharopeptide Krestin (PSK) and polysaccharopeptide (PSP). One of the most important functions of PSP and PSK is their immunomodulatory and anti-cancer actions. The present paper reviewed and summarized the pharmacological and clinical properties, as well as its background of Coriolus versicolor or PSP.

    Abstract - PSP, a polysaccharopeptide obtained from cultivated mycelia of the mushroom Coriolus versicolor, is a biological response modifier capable of showing diverse biological activities. It is a chemically homogenous substance possessing a molecular weight of approximately 100 kilodaltons. PSP is composed of 90% polysaccharides and 10% peptides. In addition to glucose, its polysaccharide constituents consist of five other sugars including arabinose, galactose, mannose, rhannose and xylose. The polypeptide constituents contain more than twenty different amino acids, notably aspartic and glutamic acids. PSP exhibits immunomodulatory and anti- tumour activities with low cytotoxicity. It has been used in Asia, particularly in China, as an adjuvant in the clinical treatment of cancer to boost the immunological status of patients undergoing chemotherapy and/or radiotherapy. In addition, PSP exhibits analgesic, anti-viral and hepato-protective effects.

    Abstract - The protein-bound polysaccharides or polysaccharopeptides produced by Coriolus versicolor are effective immunopotentiators, which are used to supplement the chemotherapy and radiotherapy of cancers and various infectious diseases. Antitumor activity of polysaccharopeptides has been documented. Several kinds of protein-bound polysaccharides have been shown to be produced by the white rot fungus, C. versicolor. Although some of these polymers are structurally distinct, they are not distinguishable in terms of their physiological activity. This review focuses on the physiologically active polysaccharopeptides of C. versicolor. In nature, C. versicolor occurs as a mushroom body, but the fungus can be grown as mycelial biomass in submerged culture in bioreactors. Mushrooms gathered in the wild, cultivated mushrooms, and the mycelial biomass of submerged culture are used to produce the polysaccharopeptides. Submerged cultures are typically carried out in batches lasting 5–7 days and at 25–27 jC. Hot water extraction of the biomass is used to recover the thermostable polysaccharopeptides that are concentrated, purified, and dried into a powder for medicinal use. In view of the documented physiological benefits of these compounds, extensive research is underway on the structure, composition, production methods, and use of new C. versicolor strains for producing the therapeutic biopolymers. Properties, physiological activity, recovery, and purification of the bioactive polysaccharopeptides are discussed.

    Ganoderma - A therapeutic fungal biofactory - R. Russell M. Paterson et.al. - Phytochemistry 67 (2006) 1985 - 2001 © (2006) The authors.


    Abstract - Ganoderma is a basidiomycete white rot fungus which has been used for medicinal purposes for centuries particularly in China, Japan and Korea. A great deal of work has been carried out on Ganoderma lucidum. The common names for preparations include Lingzhi, Munnertake, Sachitake, Reishi and Youngzhi. This review collates the publications detailing activities and compounds by representative species whilst considering the most valid claims of effectiveness. The biological activities reported of preparations from Ganoderma are remarkable and given most emphasis herein as distinct from structure/activity information. The metabolites consist of mainly polysaccharides and terpenoids. Many are activities against the major diseases of our time and so the present review is of great importance. The list of effects is huge ranging from anti-cancer to relieving blockages of the bladder. However, the reports have not all been tested scientifically with the convincing evidence reserved for assays of pure compounds. It is a prime example of an ancient remedy being of great relevance to the modern era. There does appear to be an assumption that the therapeutic effects attributed to the fungus have been proven. The next step is to produce some effective medicines which may be hampered by problems of mass production.

    Abstract - In Chinese, the name lingzhi represents a combination of spiritual potency and essence of immortality, and is regarded as the “herb of spiritual potency”, symbolizing success, well-being, divine power, and longevity. Among cultivated mushrooms, G. lucidum is unique in that its pharmaceutical rather than nutritional value is paramount. A variety of commercial G. lucidum products are available in various forms, such as powders, dietary supplements, and tea. These are produced from different parts of the mushroom, including mycelia, spores, and fruit body. The specific applications and attributed health benefits of lingzhi include control of blood glucose levels, modulation of the immune system, hepatoprotection, bacteriostasis, and more. The various beliefs regarding the health benefits of G. lucidum are based largely on anecdotal evidence, traditional use, and cultural mores. However, recent reports provide scientific support to some of the ancient claims of the health benefits of lingzhi.

    Abstract - Lingzhi (Ganoderma lucidum) is a woody mushroom highly regarded in traditional medicine and is widely consumed in the belief that it promotes health and longevity, lowers the risk of cancer and heart disease and boosts the immune system. However, objective scientific validation of the putative health benefits of Lingzhi in human subjects is lacking, and issues of possible toxicity must be addressed. The present double-blinded, placebo-controlled, cross-over intervention study investigated the effects of 4 weeks Lingzhi supplementation on a range of biomarkers for antioxidant status, CHD risk, DNA damage, immune status, and inflammation, as well as markers of liver and renal toxicity. It was performed as a follow-up to a study that showed that antioxidant power in plasma increased after Lingzhi ingestion, and that 10 d supplementation was associated with a trend towards an improved CHD biomarker profile. In the present study, fasting blood and urine from healthy, consenting adults (n 18; aged 22–52 years) was collected before and after 4 weeks supplementation with a com- mercially available encapsulated Lingzhi preparation (1·44 g Lingzhi/d; equivalent to 13·2 g fresh mushroom/d) or placebo. No significant change in any of the variables was found, although a slight trend toward lower lipids was again seen, and antioxidant capacity in urine increased. The results showed no evidence of liver, renal or DNA toxicity with Lingzhi intake, and this is reassuring. The present study of the effects in healthy, well-nourished subjects provides useful, new scientific data that will support controlled intervention trials using at- risk subjects in order to assess the therapeutic effect of Lingzhi in the promotion of healthy ageing.

    Shilajit (Mumijo) : Unraveling the mystery - Sabinsa Corp. - © (2007) Sabinsa Corp., India


    Abstract - Shilajit aka mumio (mumijo, mumie, moomiyo, mummio, mummiya) is a blackish brown substance found in the serene surroundings of the Altai and the Himalaya in Central-Asia at altitudes between 1000 and 5000 m. In Ayurveda, Shilajit is classified as a 'rasayan' (meaning rejuvenator and immunomodulator in Sanskrit) and as a 'medhya rasayan' [rejuvenator of 'medha' (intellect)]. Shilajit is believed to slow down the process of aging by rejuvenation and immunomodulation. Until the mid 80's, Shilajit was described as an inorganic mineral, a bitumen, an asphalt, a mineral resin, a plant fossil exposed by elevation of the Himalayas, and so forth. Focused research has now shown that Shilajit is essentially consisting of fresh and modified remnants of humus - the characteristic organic constituent of soils. This pdf gives a detailed scientific breakdown of the properties and components of Shilajit / Mumijo.

    Chemistry of Shilajit, an immunomodulatory Ayurvedic rasayan - Shibnath Ghosal - Department of Pharmaceutics, Banaras Hindu University, Varanasi-5, India © (1990) The author.


    Abstract - The chemical polemics in the reported literature on shilajit are resolved. This study shows that humification of latex and resin-bearing plants is responsible for the major organic mass (80-85%) of shilajit. The low mol. w t . chemical markers ( & l o % ) , viz. aucuparins, oxygenated dibenzo-K -pyrones and triterpenic acids of the tirucallane type (free and conjugated), occurring in the core structure of shilajit humus, are the major active constituents of Himalayan shilajit. The therapeutic effects of shilajit are the consequences of hormonal control and regulation of immunity.

    Abstract - The protective effect as regards the liver nuclear chromatin of the preparation «Mumiyo-Vitas» in condition of genotoxic action of the chlorophose is revealed. This effect is realized in conditions of profilactic intraperitoneal way of the preparation injection to the experimental animals (thrice-repeated before 36, 24 and 0,5 h the poison in dose 240 mg/kg of the body mass) and related to the antioxidant action as regards the lipids chromatin peroxidation processes. The antioxidant-genoprotective effect of the preparation is more expressed as regards the transcriptionally active chromatin fraction and is correlated to the mortality reduction of the experimental animals. In the realization of this effect mainly the c chromatin phosphatidylcholin lipids and DNA participate.

    Complement-fixing Activity of Fulvic Acid from Shilajit and Other Natural Sources - Igor A. Schepetkin et.al. - Department of Veterinary Molecular Biology, Montana State University, Bozeman, MT 59717 © (2009) The authors.


    Abstract - Shilajit has been used traditionally in folk medicine for treatment of a variety of disorders, including syndromes involving excessive complement activation. Extracts of Shilajit contain significant amounts of fulvic acid (FA), and it has been suggested that FA is responsible for many therapeutic properties of Shilajit. However, little is known regarding physical and chemical properties of Shilajit extracts, and nothing is known about their effects on the complement system. [...] All Shilajit fractions exhibited dose-dependent complement-fixing activity in vitro with high potency. Furthermore, we found a strong correlation between complement- fixing activity and carboxylic group content in the Shilajit fractions and other FA sources. These data provide a molecular basis to explain at least part of the beneficial therapeutic properties of Shilajit and other humic extracts.

    Mumijo Traditional Medicine - Fossil Deposits from Antarctica - Aiello A, et.al. - Agrotechnology and Food Innovations, Wageningen University and Research Center, The Netherlands. © (2008) The authors.


    Abstract - Mumijo is a widely used traditional medicine, especially in Russia, Altai Mountains, Mongolia, Iran, Kazachstan and in Kyrgystan. Mumijo preparations have been successfully used for the prevention and treatment of infectious diseases; they display immune-stimulating and antiallergic activity as well. In the present study, we investigate the chemical composition and the biomedical potential of a Mumijo(-related) product collected from the Antarctica. [....] It is concluded that this new Mumijo preparation has distinct and marked neuro-protective activity, very likely due to the content of glycerol ether derivatives.

    Selected herbals and human exercise performance - Luke R. Bucci - The American Journal of Clinical Nutrition. © (2000) The author.


    Abstract - Herbs have been used throughout history to enhance physical performance, but scientific scrutiny with controlled clinical trials has only recently been used to study such effects. The following herbs are currently used to enhance physical performance regardless of scientific evidence of effect: Chinese, Korean, and American ginsengs; Siberian ginseng, mahuang or Chinese ephedra; ashwagandha; rhodiola; yohimbe; Cordyceps fungus, shilajit or mummio; smilax; wild oats; Muira puama; suma (ecdysterone); Tribulus terrestris; saw palmetto berries; Beta-sitosterol and other related sterols; and wild yams (diosgenin). Controlled studies of Asian ginsengs found improvements in exercise performance when most of the following conditions were true: use of standardized root extracts, study duration (>8 wk, daily dose >1 g dried root or equivalent, large number of subjects, and older subjects. Improvements in muscular strength, maximal oxygen uptake, work capacity, fuel homeostasis, serum lactate, heart rate, visual and auditory reaction times, alertness, and psychomotor skills have also been repeatedly documented. Siberian ginseng has shown mixed results. Mahuang, ephedrine, and related alkaloids have not benefited physical performance except when combined with caffeine. Other herbs remain virtually untested. Future research on ergogenic effects of herbs should consider identity and amount of substance or presumed active ingredients administered, dose response, duration of test period, proper experimental controls, measurement of psychological and physiologic parameters (including antioxidant actions), and measurements of performance pertinent to intended uses.

    Rhodiola rosea - A Phytomedicinal Overview - Richard P. Brown et.al - HerbalGram - The Journal of the American Botanical Council Issue: 56 Page: 40-52 © (2004) The authors.


    Abstract - For centuries, R. rosea has been used in the traditional medicine of Russia, Scandinavia, and other countries. Between 1725 and 1960, various medicinal applications of R. rosea appeared in the scientific literature of Sweden, Norway, France, Germany, the Soviet Union, and Iceland.
    Since 1960, more than 180 pharmacological, phytochemical, and clinical studies have been published. Although R. rosea has been extensively studied as an adaptogen with various health-promoting effects, its properties remain largely unknown in the West. In part this may be due to the fact that the bulk of research has been published in Slavic and Scandinavian languages. This review provides an introduction to some of the traditional uses of R. rosea, its phytochemistry, scientific studies exploring its diverse physiological effects, and its current and future medical applications.

Which medicinal mushroom is the best?

Medicinal mushrooms seem like small miracles - their therapeutic properties seem to cover almost the full spectrum of human health and well-being. And this is not exaggerated. The majority of antibiotics, several chemo-therapeutic agents, most anti-cholesterol medication (statins) and some anti-HIV medication are based on fungi. Cyclosporin, a drug without which organ transplants would be impossible, is derived from a fungus as well. And so on.

In fact, most mushrooms have only been researched for a small number of therapeutic applications. The chart below gives an indication of the existing research results of the therapeutic properties that were investigated so far.


Please take notice: 'immune balancing' covers a lot of health problems, including many allergies and auto-immune related diseases. These have not been listed separately. This overview is also not complete - we will update it and refine it when more data becomes available.


Be aware of the fact that if a property is left blank for a particular mushroom this only means that this property so far has not been investigated in depth.

These results have all been achieved with extracted mushroom products (extraction using e.g. hot water, ethanol, methanol, fermentation or combinations of these) - they are not applicable to biomass or un-extracted, dried and powdered mushroom products or tinctures.
