    Immune Functions: Numerous animal and in vitro studies have shown that Cordyceps fruit body and mycelial extracts are potent immunopotentiators. Cultured fruit bodies of
    Cordyceps prepared as a water extract produced a significant increase in the phagocytic activity of Kupffer cells after oral administration in rats for 25 days, but not after two days. The increase compared to control rats was seen in a 36% greater colloidal carbon clearance value from a dosage of 200 mg/kg p.o., whereas half the amount was ineffective (Nakamura et al., 1999). A water extract of cultured C. sinensis (100 g/mL) was shown to dose-dependently reverse murine renal cell neoplasm-induced suppression of murine macrophage (J774A.1 cell line) oxidative burst (chemoluminescent), following co-incubation of the extract with the tumor cells. At 8 hours co-incubation, the activity of the macrophages was significantly enhanced (Jiao and Lau, 1998).

    Selected herbals and human exercise performance.
    Bucci LR [Record supplied by publisher], Weider Nutrition International, Salt Lake City.

    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.

    Inhibitory effect of cordyceps sinensis and cordyceps militaris on human glomerular mesangial cell proliferation induced by native LDL.
    Zhao-Long W, Xiao-Xia W, Wei-Ying C, Department of Internal Medicine, Zhong Shan Hospital, Shanghai Medical University, Shanghai, P.R. China.

    Native LDL, in low concentrations, promotes proliferation of cultured human glomerular mesangial cells. LDL stimulated [(3)H]-thymidine incorporation into DNA of human glomerular mesangial cells. Increased concentrations of LDL led to increased [(3)H]-thymidine incorporation. When LDL concentrations were 5, 10 and 50 &mgr;g ml(-1), [(3)H]-thymidine incorporation was 919.5+/-216, 1106+/-132, and 1200+/-210, respectively. When Cordyceps sinensis 100, 200, 300, 400 &mgr;g ml(-1) plus LDL 10 &mgr;g ml(-1) were added, [(3)H]-thymidine incorporation was 99+/-19 and 53+/-8, respectively, P<0.01 compared with controls. With Cordyceps militaris at similar concentrations plus LDL 10 &mgr;g ml(-1), [(3)H]-thymidine incorporation was respectively 192+/-75, 168+/-66, 145+/-53 and 72+/-16, P<0.01 compared with controls. The data suggest that LDL may play a critical role in mediating mesangial cell hypertrophy or proliferation involved in the development of glomerulosclerosis. Cordyceps sinensis and Cordyceps militaris inhibited, to a certain degree, proliferation of cultured human glomerular mesangial cell induced by LDL. Copyright 2000 John Wiley & Sons, Ltd.

    Protein constituent contributes to the hypotensive and vasorelaxant activities of Cordyceps sinensis.
    Chiou WF, Chang PC, Chou CJ, Chen CF, National Research Institute of Chinese Medicine, Taipei, Taiwan, ROC.

    Cordyceps sinensis is a herb medicine in China for the treatment of general debility after sickness and for persons of advanced age. In the present study, cordyceps sinensis was extract by phosphate buffer saline (PBS) and dialyzed overnight against PBS using a membrane cut off at 3,500 dalton molecular weight. The resulting macromolecule fraction (defined as CS) was assayed in anesthetized rats for hypotensive effects and in isolated aorta for vasorelaxant effects. Intravenous injection of CS (8,16, 24 and 32 mg/kg, respectively) suppressed significantly the mean arterial pressure (MAP) in a dose-dependent manner. 32 mg/kg of CS induces the maximal hypotensive response with a 58 +/- 4 mm Hg (from 107 +/- 6 to 49 +/- 3 mm Hg) change in MAP and a over 45 min action duration. In aortic rings precontracted with phenylephrine treatment with CS between 0.5 and 500 microg/ml induced dose dependent relaxation. Maximal vasorelaxant response evoked by 150 microg/ml CS was 68.9 +/- 7.3%. Furthermore, CS-induced vasorelaxation is mediated by the endothelium possibly by stimulating the release of the nitric oxide and endothelium-derived hyperpolarizing factor. In conclusion, the present study revealed that presence of a constituent in CS which reduces MAP by relaxing the vascular beds directly. However, the effect may be caused by a single active ingredient or by the combined action of many active agents found in the extract. PMID: 10755473, UI: 20216249

    Effects of the mycelial extract of cultured Cordyceps sinensis on in vivo hepatic energy metabolism and blood flow in dietary hypoferric anaemic mice.
    Manabe N, Azuma Y, Sugimoto M, Uchio K, Miyamoto M, Taketomo N, Tsuchita H, Miyamoto H, Department of Animal Sciences, Kyoto University, Japan.

    The beneficial effects of a traditional Chinese medicine, Cordyceps sinensis (Cs), on mice with hypoferric anaemia were evaluated by NMR spectroscopy. Experimental hypoferric anaemia was induced in mice by feeding with an Fe-free diet for 6 weeks. They were then given extract from cultured Cs (200 mg/kg body weight daily, orally) and were placed on an Fe-containing recovery diet (35 mg Fe/kg diet) for 4 weeks. In vivo 31P and 2H NMR spectra acquired noninvasively and quantitatively at weekly intervals were used to evaluate hepatic energy metabolism and blood flow in the mice. During the 4-week Cs-extract treatment, consistent increases were observed in liver beta-ATP: inorganic phosphate value by liver 31P NMR spectroscopy, representing the high energy state, and in blood-flow rate as determined by 2H NMR spectroscopy of deuterated water (D2O) uptake after intravenous injection of D2O. The haematological variables (the packed cell volume and the haemoglobin level) and the hepatic intracellular pH, which was determined from the NMR chemical shift difference between the inorganic phosphate peak and the alpha-phosphate peak of ATP, were not significantly different between Cs-extract-treated and control mice. As blood flow and energy metabolism are thought to be linked, the Cs-extract-increased hepatic energy metabolism in the dietary hypoferric anaemic mice was concluded to be due to increased hepatic blood flow.

    Interkingdom host jumping underground: phylogenetic analysis of entomoparasitic fungi of the genus cordyceps.
    Nikoh N, Fukatsu T, National Institute of Bioscience and Human-Technology, Agency of Industrial Science and Technology, Tsukuba, Japan.
    Most members of the ascomycetous genus Cordyceps are endoparasitic fungi of insects and other arthropods, but about 20 of the 300 described species are parasitic to hart's truffles, Elaphomyces spp. In order to understand the evolution of host specificity and the process of interkingdom host jumping in Cordyceps, we investigated the phylogenetic relationships of 22 representatives, including 4 truffle parasites and 18 insect parasites, based on nuclear and mitochondrial rDNA sequences. Five monophyletic groups were identified in both nuclear and mitochondrial phylogenies. In three of the five clades, the members utilized hosts from the same insect group, suggesting that the endoparasite-host connections have been conserved to some extent. On the other hand, it was also shown that major host shifts between distantly related insects must have occurred repeatedly. Notably, phylogenetic analyses strongly suggested that parasites of hart's truffles originated from parasites of cicada nymphs during the evolution of the CORDYCEPS: The common habitats of cicada nymphs and hart's truffles, deep underground and associated with tree roots, suggest that the interkingdom host jumping from Animalia to Fungi might have been promoted by the overlapping ecological niche of the unrelated hosts. This finding provides an impressive case of a drastic host shift in favor of the host habitat hypothesis. PMID: 10742053, UI: 20206862

    Efficacy of a pure compound H1-A extracted from Cordyceps sinensis on autoimmune disease of MRL lpr/lpr mice.
    Yang LY, Chen A, Kuo YC, Lin CY, Department of Pediatrics, Veterans General Hospital, Taipei, Taiwan, Republic of China.

    Cordyceps sinensis (CS) is a traditional Chinese medicine with immunomodulatory effect and is effective in improving the survival of lupus mice. In the present study we isolated a pure compound (H1-A) from CS and investigated its effect on inhibiting autoimmune disease progression in MRL Ipr/Ipr mice. Our results demonstrated that MRL Ipr/Ipr mice treated daily with H1-A (40 microg/kg/d orally) for 8 weeks had a progressive reduction in anti-ds-DNA production (optical density value decreased from 0.172 +/- 0.009 to 0.112 +/- 0.015) when compared with the control group (optical density value increased from 0.141 +/- 0.036 to 0.198 +/- 0.047). In clinical presentation, the treated group had a reduction in lymphadenopathy, a delayed progression of proteinuria, and an improvement in kidney function. Histologic analysis of kidney tissue indicated that H 1-A could inhibit the mesangial proliferation that was evident in lupus nephritis. However, there was no significant change in immune complex deposition. The studies reveal that the pure compound (H1-A) may be potentially useful for treating systemic lupus erythematosus in human patients, and they provide some questions for further investigation of the pathogenesis of systemic lupus erythematosus and lupus nephritis.

    Genetic diversity and taxonomic implication of Cordyceps sinensis as revealed by RAPD markers.
    Chen Y, Zhang YP, Yang Y, Yang D, Laboratory of Cellular and Molecular Evolution, Kunming Institute of Zoology, Chinese Academy of Sciences, Yunnan, China.

    Random amplified polymorphic DNA (RAPD) markers are used to investigate genetic variation and evolutionary relationships of 29 samples of Cordyceps sinensis from different geographical populations on the Qinghai-Tibet plateau. Out of 137 RAPD bands scored, 100 are polymorphic. A correlation is revealed between geographical distance and genetic distance. The molecular phylogenetic tree suggests that the 29 samples are divided into three notable clusters, corresponding to the geographical populations, i.e., the north population (NP), middle population (MP), and south population (SP). The NP consists of 7 northern samples from Menyuan, Maqu, and Luqu, the MP consists of 8 samples from Yushu and Chengduo, and the SP consists of 14 samples from Byma Snow Mountain, Renzhi Snow Mountain, Chongcaoxiwa, and Dacaodi. It is demonstrated that extensive genetic diversity is found among different geographical populations of C. sinensis. The genetic diversity pattern of C. sinensis may be caused by the founder effects. The taxonomic status of NP, MP, and SP populations should be that they are different subspecies rather than different species. PMID: 10544805, UI: 20012048

    Structural features and hypoglycemic activity of a polysaccharide (CS-F10) from the cultured mycelium of Cordyceps sinensis.
    Kiho T, Ookubo K, Usui S, Ukai S, Hirano K, Department of Pharmaceutics, Gifu Pharmaceutical University, Japan.

    A polysaccharide (CS-F10) purified from a hot water extract of the cultured mycelium of Cordyceps sinensis was composed of galactose, glucose and mannose in a molar ratio of 4324; its molecular weight was estimated to be about 15000. The results of chemical and spectroscopic investigations suggest that CS-F10 has a comb-type structure, and has alpha-D-glucopyranosyl residues on the terminal of the side-chains and characteristic sugar residues of C. sinensis i.e., 1,5-linked beta-D-galactofuranosyl residues. CS-F10 significantly lowered the plasma glucose level in normal, streptozotocin (STZ)-induced diabetic and epinephrine-induced hyperglycemic mice after intraperitoneal administration (50 mg/kg). Administration of CS-F10 to STZ-induced diabetic mice significantly increased the activity of hepatic glucokinase. A significant reduction in the hepatic glucose output was observed following the infusion of CS-F10 using the perfused rat liver. CS-F10 also significantly decreased protein content of facilitative glucose transporter isoform 2 (GLUT2) from rat liver following i.p. administration. These effects presumably contribute to the hypoglycemic activity. PMID: 10513622, UI: 99441780

    Antitumor sterols from the mycelia of Cordyceps sinensis.
    Bok JW, Lermer L, Chilton J, Klingeman HG, Towers GH, Department of Botany, University of British Columbia, Vancouver, Canada.

    Activity guided fractionations led to the isolation of two antitumor compounds 5 alpha,8 alpha-epidioxy-24(R)-methylcholesta-6,22-dien-3 beta-D-glucopyranoside and 5,6-epoxy-24(R)-methylcholesta-7,22-dien-3 beta-ol from the methanol extract of Cordyceps sinensis. Two previously known compounds, ergosteryl-3-O-beta-D-glucopyranoside and 22-dihydroergosteryl-3-O-beta-D-glucopyranoside were also isolated. The structures of hitherto unknown sterols were established by 1D and 2D NMR spectroscopic techniques with the former synthesized in order to confirm the identity of the sugar moiety by chemical correlation. The glycosylated form of ergosterol peroxide was found to be a greater inhibitor to the proliferation of K562, Jurkat, WM-1341, HL-60 and RPMI-8226 tumor cell lines by 10 to 40% at 10 micrograms/ml than its previously identified aglycone, 5 alpha,8 alpha-epidioxy-24(R)-methylcholesta-6,22-dien-3 beta-ol.

    Inhibition of activated human mesangial cell proliferation by the natural product of Cordyceps sinensis (H1-A): an implication for treatment of IgA mesangial nephropathy.
    Lin CY, Ku FM, Kuo YC, Chen CF, Chen WP, Chen A, Shiao MS, Department of Pediatrics and Medical Research, Veterans General Hospital-Taipei, Taiwan, Republic of China.

    Cordyceps sinensis (CS) is a parasitic fungus that has been used as a Chinese medicine for a long time in the treatment of nephritis. Today, the hypothesis about the pathogenesis of immunoglobulin A nephropathy (IgAN) is that nephritogenic IgA immune complexes (IgAIC) go to the kidney to stimulate resting mesangial cells to release cytokines and growth factors. These cytokines and growth factors cause mesangial cell proliferation and release matrix, chemical mediators that lead to the glomerular injury. However, nephritogenic IgAIC in humans is still unknown. To solve this problem previously, we established an in vitro model that showed that cultured human mesangial cells (HMC) stimulated with interleukin-1 (IL-1) plus IL-6 can cause mesangial cell proliferation, increasing production of chemical mediators and superoxide anion. An in vivo model also proved that this culture medium may lead to renal injury with hematuria and proteinuria. Therefore, to fractionate the crude components that can be used in the treatment of patients with IgAN, we cultured HMC, and then an HMC activating model with HMC incubated with IL-1 and IL-6 was established. We fractionated the crude methanolic extracts from fruiting bodies of CS with the use of this in vitro inhibition of HMC activation model as our assay method. In brief, the fruiting bodies were extracted by silica gel column chromatography. One out of 6 column fractions, F-2, significantly inhibited the HMC activation by IL-1 plus IL-6. The acute toxicity test with male Institute of Cancer Research mice showed no liver toxicity or mutagenicity. Then we established an IgAN animal model with R36A (Pneumococcal C-polysaccharide purified from Streptococcus pneumoniae) as antigen and anti-R36A IgA monoclonal antibody to form nephritogenic IgA-IC, which can induce hematuria and proteinuria in mice with IgA deposition in the mesangial area. The mice in the IgAN model fed with 1% F-2 in diet had significant reduction of hematuria and proteinuria together with histopathologic improvement. Therefore this fraction was then purified by silica gel column chromatography and high-performance liquid chromatography, which got a purified compound H1-A, which can suppress the activated HMC and alleviate IgAN (Berger's disease) with clinical and histologic improvement. These results give us a new regimen for the treatment of patients with IgAN in the future. PMID: 10385482, UI: 99312208

    Activation of in vivo Kupffer cell function by oral administration of Cordyceps sinensis in rats.
    Nakamura K, Yamaguchi Y, Kagota S, Shinozuka K, Kunitomo M, Department of Pharmacology, Faculty of Pharmaceutical Sciences, Mukogawa Women's University, Nishinomiya, Japan.

    We investigated the effect of water extracts of Cordyceps sinensis (WECS) on Kupffer cell function in rats. Rats were received a single i.v. injection of a colloidal carbon solution and then the clearance rate from the blood were measured. The rats had been daily administered with WECS, p.o. at a dose of 200 mg/kg for 25 days until the day before the injection of colloidal carbon. The half-life of the colloidal carbon in the blood of rats administered WECS 200 mg/kg was significantly shorter than that of the control rats. This suggests that accelerated function of Kupffer cells is partially involved in the anti-metastatic action of WECS. PMID: 10361894, UI: 99288740

    Inhibitory effect of Cordyceps sinensis on spontaneous liver metastasis of Lewis lung carcinoma and B16 melanoma cells in syngeneic mice.
    Nakamura K, Yamaguchi Y, Kagota S, Kwon YM, Shinozuka K, Kunitomo M, Department of Pharmacology, Faculty of Pharmaceutical Sciences, Mukogawa Women's University, Nishinomiya, Japan.

    We investigated the effect of the water extract of Cordyceps sinensis (WECS) on liver metastasis of Lewis lung carcinoma (LLC) and B16 melanoma (B16) cells in mice. C57BL/6 mice were given a s.c. injection of LLC and B16 cells and sacrificed 20 and 26 days after tumor inoculation, respectively. WECS was daily administered p.o. to the mice in a dose of 100 mg/kg body weight (wt.) in the experiment of LLC and in a dose of 100 or 200 mg/kg body wt. in the experiment of B16 from one week before tumor inoculation to one day before the date of sacrifice. The tumor cells increased in the thigh in LLC-inoculated mice and in the footpad in B16-inoculated mice. The relative liver wt. of the tumor-inoculated mice significantly increased as compared to that of the normal mice due to the tumor metastasis, as verified by the hematoxylin-eosin staining pathological study in the LLC experiment. The relative liver wt. of the WECS-administered mice significantly decreased relative to that of the control mice in both the LLC and B16 experiments. WECS showed a strong cytotoxicity against LLC and B16 cells, while cordycepin (3'-deoxyadenosine), an active component of WECS, was not cytotoxic against these cells. These findings suggest that WECS has an anti-metastatic activity that is probably due to components other than cordycepin. PMID: 10230862, UI: 99245893

    Zhu JS, Halpern GM, Jones K, Department of Pediatrics, Stanford University School of Medicine, California, USA.

    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 the Fall 1998 issue of this journal (4(3):289-303), we discussed the effects of C. sinensis on antisenescence, endocrine and sexual functions, atherosclerosis, hyperlipidemia, and free radicals.

    This review presents Cordyceps sinensis (Berk.) Sacc., a fungus highly valued in China as a tonic food and herbal medicine. The extant records show the continued use of C. sinensis is now centuries old. The major chemical, pharmacological, and toxicological studies on C. sinensis and the various derived, cultured, fermented mycelial products currently in use are reviewed from the English and Chinese literature. Preclinical in vitro and in vivo studies and clinical blinded or open-label trials in to date over 2000 patients are reviewed. These studies show the main activities of the fungus in oxygen-free radical scavenging, antisenescence, endocrine, hypolipidemic, antiatherosclerotic, and sexual function-restorative activities. The safety of the fungus, its effects on the nervous system, glucose metabolism, the respiratory, hepatic, cardiovascular, and immune systems, immunologic disease, inflammatory conditions, cancer, and diseases of the kidney will be reviewed in the second part of this article to be published in the winter issue of this journal.

    [Clinical and experimental studies on elimination of oxygen free radical of jinshuibao capsule in treating senile deficiency syndrome and its deoxyribonucleic acid damage repairing effects].
    [Article in Chinese] Zhang ZJ, Luo HL, Li JS, Second Affiliated Hospital of Jiangxi Medical College, Nanchang.

    OBJECTIVE: To observe the efficacy of Jinshuibao capsule. METHODS: Senile patients of Deficiency Syndrome treated with Jinshuibao capsule (JSBC) as treated group and with starch capsule as control group. JSBC is a preparation of Cordyceps sinensis. RESULTS: (1) The superoxide dismutase (SOD) activity in senile patient were markedly lower than that in youth, while the malonyldialdehyde (MDA) level of the former was higher than that of the latter, P < 0.01; (2) The SOD activity increased and the MDA level decreased in the treated group after treatment, P < 0.01. JSBC also revealed satisfactory effect on relieving symptoms such as chilling, dizziness, lassitude in loin and legs, frequent nocturia and tinnitus, etc. Results of animal experiment wese in accordance with that of clinical observation. The unscheduled deoxyribonucleic synthesis (UDS) level of aged group before treatment was obviously lower than that of youth; after treatment, the change was very significant, and the difference between treated group and control group was also very significant (P < 0.01). Animal experiment showed that the sister chromatid exchange (SCE) of splenic cell in young mice group was markedly lower than that in aged mouse group. CONCLUSION: JSBC has not showed the SCE inducting effect, but could accelerate the repairing of damaged deoxyribonucleic acid (DNA). PMID: 9812650, UI: 99029193

    Cordyceps sinensis increases the expression of major histocompatibility complex class II antigens on human hepatoma cell line HA22T/VGH cells.
    Chiu JH, Ju CH, Wu LH, Lui WY, Wu CW, Shiao MS, Hong CY, Institute of Traditional Medicine, School of Medicine, National Yang-Ming University, Taipei, Taiwan.

    Previous studies suggest that down-regulation of the major histocompatibility complex (MHC) antigens on the cell surface of certain tumors results in an escape of immune surveillance. Cordyceps sinensis is well known for its modulatory effect on host immune system. To investigate the modulatory effect of Cordyceps sinensis on MHC class II antigen expression on hepatoma cells, immunostaining with monoclonal antibody (MAb) L243, against the HLA DR region of MHC class II antigens on human hepatoma cell line HA22T/VGH was analyzed by using flow cytofluorimetry. The degree of fluorescence intensity on L243(+) cells was expressed as relative mean fluorescence intensity (RMFI). The extract of Cordyceps sinensis (VGH-CS-ME-82, 40 micrograms/ml) was found to increase the MHC class II antigen expression on HA22T/VGH cells with the percentage of L243(+) cells 40.2 +/- 2.5 and RMFI 6.6 +/- 0.4; whereas cells without treatment disclosed the percentage of L243(+) cells 17.2 +/- 1.4 and RMFI 5.4 +/- 0.3, respectively (p < 0.05). There was a dose-related increase in the degree of fluorescence intensity in terms of RMFI on VGH-CS-ME-82 induced cells. The RMFI in cells treated with IFN-gamma 0, 0.2 and 5 ng/ml were 5.4 +/- 0.3, 8.2 +/- 0.4, and 24.9 +/- 1.5, respectively; whereas the RMFI in cells co-incubated with VGH-CS-ME-82 (40 micrograms/ml) and IFN-gamma 0, 0.2 ng/ml and 5 ng/ml were 6.7 +/- 0.2 (p < 0.05), 9.2 +/- 0.9 (p < 0.1) and 29.5 +/- 1.2 (p < 0.005), respectively. We conclude that VGH-CS-ME-82, either alone or with IFN-gamma induction, increases the MHC class II antigen expression on hepatoma cell line HA22T/VGH, which will shed light into the present immunotherapy, and make the host immune surveillance more effective against tumor cells with down-regulated MHC class II antigen expression.

    [Experimental study on effect of Cordyceps sinensis in ameliorating aminoglycoside induced nephrotoxicity].
    [Article in Chinese]
    Li LS, Zheng F, Liu ZH, Research Institute of Nephrology, Jinling Hospital, Nanjing.

    In order to evaluate the effect of Cordyceps sinensis (CS) on aminoglycoside (AG) induced nephrotoxicity, gentamycin was imposed on the young and old rats with CS administration. The renal tubular injury was ameliorated as evidenced by less prominent increment of BUN, SCr, sodium excretion, urinary NAGase and less severity of histopathological changes as compared with control. In addition, the use of CS could promote an earlier recovery of renal oxygen consumption insulin clearance, and sodium absorption in isolated perfused kidney from CS treated intoxicated rat than that from control. Possible mechanisms of CS on drug-induced nephrotoxicity include: (1) Accelerating the regeneration of tubular cells; (2) Protecting the sodium pump activity of tubular cells; (3) Attenuating the tubular cell lysosome hyperfunction stimulated by phagocytosis of AG as well as decreasing the tubular cell lipoperoxidation in response to toxic injury; (4) Reducing the tissue Ca++ content.

    Pharmacological Functions of Chinese Medicinal Fungus Cordyceps sinensis and Related Species

    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 pharmacological studies are required to ensure clinical efficacy for particular diseases. Adjuvant therapy using C. sinensis for immune function disturbances, cancer, and renal failure is possible if double-blind, randomized placebo-control clinical studies show the efficacy of this herb.
    Key words: Cordyceps sinensis, anticancer activities, hepatic function, renal function, immunomodulation, polysaccharides, modified nucleosides

    Sorry, I did not phrase my question properly. Does anyone know of any research that points to using cordyceps as an aid for endurance or anti-fatigue? I have only found one (+) int his regard, but I know many people use it for this reason.

    Size check out the studies linked to at the bottom of this page
    Cordyceps Sinensis

    There are some that support it in cyclists, but interestingly there`s one where it doesn`t improve performance
    Parcell, A. C., smith, J. M., Schulthies, S. S., Myrer, J. W. and Fellingham, G. (2004) Cordyceps Sinensis (CordyMax Cs-4) supplementation does not improve endurance exercise performance. Int J Sport Nutr Exerc Metab. 36 (3), 504-509. ``

    That was a 5 week trial on endurance trained cyclists in which no sig. difference between placebo and cordyceps was found. Same as in Effects of a commercial herbal-based formula on ex...[Med Sci Sports Exerc. 2004] - PubMed Result

    The other studies show it didn`t increase muscle tissue oxygen saturation. Sorry that doesn`t give you exactly what you`re looking for but hope it helps.

    There may also be a testosterone link between Cordyceps (See Regulation of steroidogenesis by Cordyceps sinensi...[Arch Androl. 2007 Mar-Apr] - PubMed Result and Effects of Cordyceps sinensis on testosterone prod...[Life Sci. 2001] - PubMed Result )

    So from a bit of quick research it seems to have antioxidant properties (there`s a review from 2005 of the herb) but I can`t seem to find the studies backing up the other claims except for one. Perhaps somebody that has done more research into this has some other studies I missed.

    I appreciate the help. Those were the same studies that I have found. I am still looking for more information in regards to using them as an endurance aid.

    CordyMax Cs-4 improves steady-state bioenergy stat...[J Altern Complement Med. 2001] - PubMed Result

    It's a mouse model, so take it for what it's worth, though.

    Cordy is also usually dosed 1-3g with a 7% extract. Lower extracts can be preferable because there's a lot of other beneficial things in cordyceps than just the cordydeptic acid and 2-deoxyadenosine.
