  • This study was performed to investigate the effects of dried powders and water extracts of Paecilomyces tenuipes(P. tenuipes) and Cordyceps militaris(C. militaris) on lipid metabolism, lipid peroxidation and antioxidative capacity and immune status in rats. Thirty-five male Sprague-Dawley rats weighting 195$\pm$21g were grouped into five according to body weight. Ratw were raised for four weeks with diet containing either 4%, 2%(w/w) of dried P. tenuipes powders(TP-4, TP-2) or water extracts from equal amounts of each 4% P. tenuipes and C. militaris powder(TE-4, ME-4). Food intake, weight gain of all groups were not significantly different from those of control group. Lipid metabolism in general was not significantly different among all the groups. However both dried P. tenuipes powder lowered plasma cholesterol level slightly, water extract groups showed tendency of higher plasma HDL-cholesterol and lower liver cholesterol levels than control. Plasma and liver thiobarbituric acid reactive substance(TBARS) concentrations of all the experimental groups were lower than control group. Red blood cell(RBC) and liver superoxide dismutase(SOD) activities were not generally different among all groups. Liver xanthine oxidase(XOD) activities of all groups were tended to be lower than control group. Proliferation of aplenocytes induced by mitogens, concanavalin A and lipopolysaccharide, were increased in TP-2 group. The TP-4 group showed increased CD8 T cells and MHC class II expression without changes in CD4 T cells, B cells and G/M ratio, suggesting activated cytotoxic T cell activity in vivo. Increase of G/M ratio but not of MHC class II in TP-2 group indicated the possible acute inflammatory reaction by the ingested substances in gastrointestinal tract. ME-4 group showed enhanced cellular immunity without vigorous changes of immune parameters in brief periods. In conclusion, both P. tenuipes and C. militaris stimulated antioxidant capacity and immune status in rats. Among groups, water extract of C. militaris was most effective in both capacities, though dried powder of P. tenuipes at 2% dietary level was more effective in antioxidant activity, as various results by different strains were observed.(Korean J Nutrition 34(3) : 271~284, 2001)

  • The antioxidative activity and bioactivity of water, ethanol, and methanol extracts from Paecilomyces japonica (PJ), Cordyceps militaris (CM), and cordycepin-enriched C. militaris JLM0636 ($CM{\alpha}$) were tested in in vitro experimental models. The PJ water extract showed the highest extraction yield (42.53%). The highest content of phenolic compounds and flavonoids were found in the water extract of PJ, 2.72% and 1.73%, respectively. The major minerals were K, Mg, and Ca. The water extracts of PJ also showed the highest DPPH free radical scavenging activity and reducing power. Linoleic acid peroxidation and antioxidative activities were strong in $CM{\alpha}$. The methanol extracts of PJ showed the highest inhibition activity against tyrosinase. Fibriolytic activity was higher in $CM{\alpha}$ than in CM. These results may provide basic data to understand the biological activities of bioactive materials derived from $CM{\alpha}$ for the development of functional foods, cosmetics, and antithrombotics.

  • This study aimed to evaluate the protective effect of cordycepin-increased Cordyceps militaris strain on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity and oxidative stress in rats. Male Sprague-Dawley rats were randomly divided into five groups (n=6) based on six dietary categories: normal (N), $CCl_4$ control (C), $CCl_4$ plus Paecilomyces japonica (CPJ) (3%, w/w), $CCl_4$ plus C. militaris (CCM) (3%, w/w), and $CCl_4$ plus cordycepin-increased C. militaris ($CCM{\alpha}$) (3%, w/w). The activities of the liver marker enzymes ALT, AST, and LDH and the levels of lipid peroxidation were increased in the $CCl_4$-treated groups, but these parameters were significantly decreased in the $CCM{\alpha}$ group. The TBARS content in the liver homogenate, microsome, and mitochondrial fractions of the C group was significantly elevated compared with the N group. However, in the $CCl_4$-treated groups, $CCM{\alpha}$ group was significantly lowered in the TBARS levels of hepatic homogenate and microsomal fractions. The C group showed a significant decrease in the levels of plasma and hepatic glutathione, whereas they were significantly increased in the $CCM{\alpha}$ group. Accordingly, cordycepin-increased C. militaris may be an ideal animal model for studying hepatoprotective effects.

  • This study is aimed to evaluate the protective effect of Cordycepin-enriched Cordyceps militaris (CM${\alpha}$) strain on orotic acid (OA)-induced fatty liver in rats. OA treatment induced the retardation of body weight gain and enlargement of the liver. The activities of liver marker enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), Alk. phosphatase and Cholinesterase were increased when treated with OA, but these parameters were significantly decreased in the CM${\alpha}$ group. The current study observed significant elevations of thiobarbituric acid-reactive substance (TBARS) levels. However, among the OA groups, the CM${\alpha}$ group showed significantly low TBARS levels of hepatic homogenate. The OA group resulted in a significant decrease in the levels of plasma and hepatic glutathione, but these reductions were significantly increased in the CM${\alpha}$ group. These effects were more pronounced in the CM${\alpha}$ group than in the PJ or CM groups in Orotic acid treated rats. Accordingly, Cordycepin-enriched Cordyceps militaris (CM${\alpha}$) may be an ideal candidate for hepatoprotective effects in animal models.

  • The effects of mycelium of Cordyceps militaris on the growth, the lipid metabolism, the serum protein levels and the enzyme activities in male rats were studied. Sprague-Dawley rats were given four different types of diets for a succeeding period of five weeks: either a control diet, a control diet supplemented with 2%, 3% or 4% mycelium of Cordyceps militaris (CM) powder. The body weight gain, hepatic weight, feed efficiency ratio and the feed intake of the rats given diets with 2%, 3% or 4% CM were similar to those in rats given the control diet. The concentrations of hepatic total lipid and triglyceride of rats fed the 3% or 4% CM diets were significantly lower than those of rats fed the control diet. But the concentrations of hepatic total cholesterol and phospholipid of rats fed the all CM diets were similar to those of rats fed the control diet. The concentrations of total lipid, total cholesterol, triglyceride phospholipid, and the atherogenic index, and the activities of glutamic oxaloacetic transaminase and lactic dehydrogenase in serum of rats fed the all CM diets were significantly lower than those of rats fed the control diet. No differences were noted in the concentrations of HDL-cholesterol, LDL-cholesterol, total protein, albumin and creatinine, and the activities of glutamic pyruvic transaminase, ${\gamma}$ -glutamyltranspeptidase and alkaline phosphatase in the serum among the rats with on all the experimental diets. These results showed that the all CM diets feeding decreased the total cholesterol, the triglyceride, the phopholipid, and the atherogenic index in serum of rats.

  • Silkworm (Bombyx mori) pupae have been widely worked in wound dressing, hepatoprotective activity, antigenotoxicity, control of glucose level and anti-cancer activity. To investigate the anti-obesity activity of ethanol extract of silkworm pupae powder fermented with Cordyceps militaris (ESfC), the free glycerol release and cAMP concentration as well as fat accumulation were measured in the primary adipocytes of SD (Sprague Dawley) rats and high fat diet (HFD)-treated C57BL/6 mice treated with 12 weeks. Firstly, the presence of the cordycepin with lipid lowering effect was confirmed in ESfC using HPLC analysis. The level of free glycerol and cAMP concentration was significantly increased in the primary adipocytes treated with high dose of ESfC ($400{\mu}g/ml$) although these levels were consistently maintained in other dose ESfC treated groups. In HFD-induced obesity model, the increased fat weight and size of adipocytes in HFD+Vehicle treated group was recovered in HFD+ESfC treated group. Also, the liver weight and the number of lipid droplets were higher in HFD+Vehicle treated group than No treated group. But, this level was significantly decreased in HFD+ESfC treated group compared with HFD+Vehicle treated group. Furthermore, a similar recovery was detected on the phosphorylation of periliphin and HSL, and ATGL expression. Overall, the results of the present study provide some scientific evidences that ESfC can stimulate lipolysis in primary adipocytes and prevent fat accumulation in HFD-treated obesity model, and therefore have the potential for use as anti-obesity agents to treat obese patient.

  • The concentration of cordycepin produced by crossbred Cordyceps militaris JLM 0636 (CM${\alpha}$) was 7.42 mg/g dry weight, which was 7-fold higher than that of C. militaris (CM). However, cordycepin was not detected in Paecilomyces japonica (PJ). The improvement effects of CM${\alpha}$, CM and PJ on orotic acid (OA)-induced fatty liver in male Sprague-Dawley rats was investigated. Rats were randomly divided into five groups (n=6) based on five dietary categories: normal (N), OA control (C), OA plus 3% (w/w) PJ (PJ), OA plus 3% CM (CM), and OA plus 3% CM${\alpha}$ (CM${\alpha}$). OA treatment induced the retardation of body weight gain and enlargement of the liver. The concentration of hepatic triglyceride was markedly increased by OA-feeding, whereas this rise was significantly reduced by simultaneous feeding of OA, PJ, CM, and CM${\alpha}$, and this phenomenon was more pronounced by cordycepin-enriched CM${\alpha}$. The contents of total lipid, triglyceride, and free fatty acid in the serum were significantly or slightly lower in the OA control group than those of the N group, but there were no significant differences among the OA treatment groups. The hepatocytes in the OA-induced fatty liver contained numerous large lipid droplets, but PJ, CM, and CM${\alpha}$ feeding prevented the OA-induced lipid droplet accumulation in the hepatocytes. This effect was more pronounced in cordycepin-enriched CM${\alpha}$ than in PJ or CM in OA treatment rats. Accordingly, cordycepin-enriched CM${\alpha}$ could be an ideal candidate material as a dietary supplement in healthy functional foods to improve the effects of fatty liver.

  • Entomopathogenic fungus Cordyceps militaris is famous for its medicinal efficacies. It has been reported to have various pharmacological activities such as anti-tumour, insecticidal, antibacterial, immunomodulatory and antioxidant. In this study, we investigated the effect of the extract of C. militaris (MPUN8501), which was identified by the analysis of the nucleotide sequences of 5.8S ribosomal RNA, on the function of liver. C. militaris powder was extracted using hot water extracts method as time, volume and temperature and using method as differential polarity of organic solvent. Each fraction was tested for the improvement of hepatic enzyme alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activity. The BuOH extracts (CME) had highest activity which was used for the test of toxicity and efficacy of C. militaris. The enhancing effect of CME on the activity of ADH and ALDH was much more than medicine, drink, natural tea etc. Thus CME promoted the resolution of alcohol and acetaldehyde in rats, inducing recovery to normal condition rapidly. Furthermore, oral administration of CME effectively protected the carbon tetrachloride-induced acute hepatic injury as revealed by the hematological parameters (levels of sGOT and sGPT) and histological observation. CME was ascertained to be safe by regulatory toxicity studies of single dose toxicity and genotoxicity. These results suggest that CME would be useful for the maintaining normal hepatic activity as a functional health food.
