  • In this study, we examined the anti-diabetic activity in vitro by the mixed Korean herb water extracts(JDG) composed of Lycium chinense, Cordyceps militaris, and Acanthopanax senticosus on hepatic glucose-regulating enzyme activities such as glucokinase(GK), acetyl-CoA carboxylase(ACC), and inhibition activity of $\alpha$-glucosidase. The hepatic cytosol fraction of a type II diabetic animal(Goto-Kakizaki rat) was used in GK and ACC activity assays. JDG mixed water extracts significantly increased the hepatic GK and ACC activity. The highest anti-$\alpha$-glucosidase activity was observed in JDG 5 water extract when compared to the acarbose control, inhibitor of $\alpha$-glucosidase. We suggest that Lycium chinense, Cordyceps militaris, and Acanthopanax senticosus mixed water extracts may exert an anti-diabetic activity by enhancing the glucose metabolism and may be used as natural $\alpha$-glucosidase inhibitors in type 2 diabetic conditions.

  • 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.

  • To classify fungal species employed for pharmacological effects, mycelial proteins of six isolates of Ganoderma lucidum, five isolates of Schizophyllum commune and five isolates of Cordyceps spp. were separated on polyacrylamide gel to compare them by esterase, acid phosphatase, leucine aminopeptidase and peroxidase patterns. Similarity of isozyme patterns among the isolates of G. lucidum IY003, IY004, IY005 and IY008 was indicated over 70%, but that among the isolates of G. lucidum IY009, IY010 and others was indicated from 48% to 9%. Highest similarity of isozymes of S. commune was observed to be between IY803 and IY805, and similarity between these two isolates was 57%. Similarity among other isolates was shown to be from 40% to 56%. Isozyme patterns of Cordyceps spp. were comparatively different, even though they were originated from the same kind of insect as their isolate. Similarity between Cordyceps spp. IY901 and IY904, which was isolated from moths, was 67% and that of IY905 and IY909, which was originated from the larvae, was 42%. Similarity among other isolates was shown to be from 12% to 67%.

  • Cordyceps militaris is a medicinal fungus which has been used for patient suffering from cancer in Oriental medicine. It was previously reported that C. militaris extracts are capable of inhibiting tumor growth and inducing apoptosis; however, the anti-poliferative effects of human cancer cells have been poorly understood. In this study, to elucidate the anti-cancer mechanisms of human cancer cells by treatment with aqueous extract of C. militaris (AECM), we investigated the anti-proliferative effects of AECM in human hepatocarcinoma Hep3B cells. AECM treatment inhibited the growth of Hep3B cells and induced the apoptotic cell death in a concentration-dependent manner such as formation of apoptotic bodies and increased populations of apoptotic-sub G1 phase. The induction of apoptosis by AECM was connected with a proteolytic activation of caspase-3 and caspase-8. and concomitant degradation of poly (ADP-ribose) polymerase (PARP) and ${\beta}$-catenin proteins. Furthermore, caspase-3 inhibitor, z-DEVD-fmk, significantly inhibited AECM-induced apoptosis demonstrating the important role of caspase-3 in the bserved cytotoxic effect. Taken together, these findings suggest that AECM-induced inhibition of human hepatocarcinoma cell proliferation is associated with the induction of apoptotic cell death via activation of caspase-3 and C. militaris may have therapeutic potential in human cancer.

  • The effect of 12 edible mushroom species on the antioxidant and cytotoxicity on cancer cells were studied Methanol extract of Lyophyllum ulmarium, Cordyceps militaris and Sarcodon aspratus showed $30\~60\%$ DPPH radical scavenging activity and $39\~53\%$ protective effects against the cytotoxicity of $B_2O_2$. Methanol extracts of Sarcodon aspratus, Lyophyllum ulmarium, Cordyceps militaris, Agaricus blazei and Ganoderma lucidum revealed high inhibitive activities in cytotoxicity on human leukemia tells such as promyelocytic leukemia cell (HL60) and histiocytic lymphoma cell (U937). Highest toxicity was observed against HL60 cells in Sarcodon aspratus methanol extract showing $70.5\%$ inhibition at 1mg/mL whereas Cordyceps militaris methanol extract showed $81.5\%$ inhibition against U937 cells. Most water extracts of edible mushrooms exhibited the lowest effect against HL60 and U937 cells compared to methanol extract. These extract did not show cytotoxic effects against human lymphocyte. Results revealed 5 kinds of edible murshroom (Cordyceps militaris, Agaricus blaxei, Lyophyllum ulmarium, Ganoderma lucidum and Sarcodon aspratus) have strong antioxidative and in vitro anticancer efforts.

  • The comparative effects of the fibrinolytic action, antioxidative activity, and tyrosinase inhibition of Cordyceps militaris powder and fermented Cordyceps militaris powders were investigated using several microscopic organisms. The nutritional components such as phenolic compounds, flavonoids, and minerals were also measured. The total phenolic compounds and flavonoid concentrations were highest in the Cordyceps militaris powder fermented by Aspergillus oryzae. Major minerals were K, Ca, Mg, and Zn. Native polyacrylamide gel electrophoresis (native-PAGE) analysis of the total protein patterns of Cordyceps militaris powder and fermented Cordyceps militaris powders revealed slight varietal differences. Fibrinolytic activity was highest in the Cordyceps militaris powder fermented by Bacillus subtilis and Aspergillus kawachii. The DPPH radical scavenging activity was slightly stronger in the powder fermented by Monascus purpureus; however, these samples all exhibited a relatively low activity when compared with butylated hydroxytoluene (BHT). Tyrosinase inhibition activity was stronger in the powder fermented by Aspergillus oryzae than in unfermented powder. These results may provide basic data for understanding the biological activities and chemical characteristics of Cordyceps militaris powder fermented by several microscopic organisms for the development of functional foods.
