  • This study was carried out to investigate infection process, symptoms and main component of the domestic silkworm, Bombyx mori. larvae and pupa infected with the entomopathogenic fungus Cordyceps, Paecillomyces tenuipes. The Cordyceps, Paecillomyces tenuipes, was highly infectious to the silkworms. A pathogenicities of Cordyceps, Paecillomyces tenuipes, may be highly virulent because of the low resistance or high susceptibility of the silkworms. The silkworm larva infected with Cordyceps formed phialospores on the phialides at the imperfect stage of the genus Cordyceps, But silkworm pupa infected with Cordyceps formed ascospores in the asci at the perfection stage of the genus Cordyceps. The results of analysis of health silkworm pupa and silkworm pupa infected with Cordyceps were obtained that amino acid, fatty acid, and nucleoside were very different.

  • The cultural characteristics and antibacterial activities of Cordyceps militaris and Paecilomyces tenuipes were compared. The mycelial growth was the highest on MCM (Mushroom Complete Medium) for C. militaris and on YMA (Yeast Malt Agar) for P. tenuipes. But the mycelial density on MMM (Mushroom Minimal Medium) was lower than other on media. The optimum mycelial growth was observed at $25^{\circ}C$. C. militaris was low mycelial growth when it was transferred over 5 times generation. The carbon source for the optimum mycelial growth was fructose of monosaccharide, maltose of disaccharide and dextrin of polysaccharide. The calcium nitrate of organonitrogen was found the best mycelial growth on C. militaris, while the sodium nitrate observed to be well for mycelial growth on P. tenuipes. The ammonium tartrate was observed to be the best among the inorganonitrogen used for mycelial growth. Antibacterial activities were found out just C. militaris against Bacillus cereus of Gram (+).

  • Traditional Korean fermented herbal plants are potential sources of new food that promote health, but they are still produced by yeast, fungi or bacteria fermentation. In the present work, mushroom (Paecilomyces tenuipes and Cordyceps militaris) fungal dongchunghacho were used to fermented Glycyrrhiza uralensis Fischer (licorice) or mixed with pupa. The pupa were tested as solid substrates for the production of corcycepin, liquiritin, and liquiritigenin. The fermented substrates were analyzed the content of cordycepin, liquiritin, liquiritigenin, and glycirrhizin productivity and inhibitory activity of NO. The cordycepin content of 70% EtOH extract from the fermented mixture of licorice and 50% pupa with C. militaris increased maximum at 33 times. Pupa was very excellent for the production of cordycepin. The liquiritin content was decreased in all the assays inoculated with P. tenuipes and C. militaris dongchunghachos. The liquiritigenin content was higher when fermented with P. tenuipes than C. militaris. The addition of pupa significantly reduced the liquiritin content and glycyrrhizin production. As a result, the liquiritigenin content increased in fermented P. tenuipes and C. militaris, and liquiritin and glycyrrhizin decreased. The inhibition of NO production in the different ethanolic extracts fermented with licorice and pupa was also significantly increased and higher than that of a nonfermented extract in higher polar solvent extracts. The contents of cordycepin and biological active compounds were altered in accordance with the concentration of pupa and fungi. This study provides basic data for use in developing dongchunghacho fungi as a functional food resource.

  • 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.

  • Mushroom is known for anti-inflammatory and anti-oxidative potential. This study provides evidence that the inhibitory effect of mushroom on the expression of pro-inflammatory cytokines in human keratinocytes, HaCaT cells. To define the underlying mechanisms of action, tumor necrosis factor${\alpha}$/$IFN{\gamma}$-activated human keratinocytes model was used. Mushroom significantly inhibited the expression of cytokines in HaCaT cells. Taken together, the results demonstrate that mushroom inhibited inflammtion, suggesting that mushroom (DW extract: Grifola frondosa Cordyceps militaris), (Ethanol extract: Ganoderma lucidum, Lentinus edodes, Cordyceps militaris, Flammulina velutipes) might be a candidate for the treatment of skin inflammation.

  • The hepatoprotective effect of Cordyceps militaris culture broth was determined using HaM/ICR strain mice. Compared to control, the intra-peritoneal injection of benzo($\alpha$)pyrene (B($\alpha$)P) remarkably increased the activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in the serum and the level of lipid peroxide (LPO) in liver tissue, which mean the liver was damaged by B($\alpha$)P. However, compared to B($\alpha$)P, oral administration of C. militaris culture broth showed decrement of AST, ALT, and LPO activities and increment GST activity and GSH level in liver tissue. These suggest that C. militaris culture broth recovered hepatic damage induced by B($\alpha$)P.
