This study was performed to observe the effects of the feeding physiological activity substance in Cordyceps militaris hot-water extract intake on the improvement of lipid components and metabolic enzyme activities in the serum of dietary hyperlipidemic rats (SD strain, male) fed the experimental diets for 5 weeks. The concentrations of cholesterol (total cholesterol, ${\beta}$-lipoprotein, LDL-cholesterol, free cholesterol and cholesteryl ester), atherosclerotic index, triglyceride (TG), phospholipid (PL) and blood glucose in sera were remarkably lower in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. In the ratio of HDL-cholesterol concentration was higher percentage in the Cordyceps militaris extract intake group than in the hyperlipidemic rats. The activities aminotransferase (AST, ALT) in sera were rather lower in the Cordyceps militaris extract administration than in the hyperlipidemic rats. From the above research, Cordyceps militaris extract were effective on the improvement of the lipid compositions in sera of dietary hyperlipidemic rats.

The optimum conditions of Cordyceps militaris mycelial growth, purification and characteristics of branched-chain amino acid aminotransferase [BCAT(EC 2.6.1.42)] in this mycelium were studied. Optimum pH, temperature and medium of culture of mycelia were 5.5, $22.5^{\circ}C$ and Hamada medium (HM), respectively. BCAT in homogenate of this mycelia was precipitated by 20-40% saturated solution of ammonium sulfate and then purified by DEAE (diethylaminoethyl)-Sephadex A-50 column chromatography with linear concentration gradient and Sephadex G-200 gel filtration. A single band of purified enzyme was detected on SDS-PAGE (sodium dodecylsulfate-polyacrylamide gel electrophoresis). Optimum pH and temperature of BCAT were found to be 7.8 and $29^{\circ}C$, respectively. It showed activity toward L-leucine, L-isoleucine and L-valine as a substrate. The Km values of this enzyme for L-leucine were determined to be 5.88 mM for L-leucine.

This study investigated the quality characteristics of the Seolgiddeok samples prepared with various amounts(0, 0.5, 1.0 and 2.0%) of Paecilomyces japonica powder by examining proximate compositions, color, texture and sensory quality. The composition of the Paecilomyces japonica powder was measured as follows: moisture(7.40%), crude protein(55.77%), crude lipid(7.1l%), and crude ash(5.39%). With increasing Paecilomyces japonica powder content, the moisture and crude protein content of the Seolgiddeok increased; however crude fat and ash contents decreased. In terms of color, the lightness of the Seolgiddeok decreased and yellowness and redness increased with increasing amounts of Paecilomyces japonica powder. Among textural characteristices hardness, cohesiveness, and gumminess were decreased, but springiness increased according to the addition level of Paecilomyces japonica powder. For the sensory evaluation, the overall quality of the SP-l.0% group was not significantly different than the control group(SP group). In conclusion, the optimal addition amount of Paecilomyces japonica powder for Seolgiddeok is proposed as 1% of total weight.

The fruiting bodies of Paecilomyces japonica been used for an anticancer and immuno-stimulating agent as an oriental medicine, Antimutagenecity test with SOS chromotest and antioxidant test with NBT method were carried out using the concentrated culture broth, the extract of mycelia, and that of fruiting bodies. Among the sample extracts tested, the extract of fruiting bodies was most effective to antimutagenecity against the mutagens tested such as MNNG, ethidium bromide(EtBr), 2-aminofluorene(AF) and nitrofluorene(NF). Antimutagenic activity of all the extracts were very effective against mutagen, MNNG. When the extracts were added to certain concentration, antimutagenic activity was enhanced against mutagen, MNNG and NF. Antioxidant activity of the extract from fruiting bodies was highest. However, its activity was very low, compared to ascorbic acid.

The purpose of this research was to investigate the immuno-modulatory effect and anti-carcinogenic property of Cordyceps militaris(CM) and/or Paecilomyces japonicus (PJ). The proliferation of cultured splenocytes and thymocytes were enhanced by the addition of 10 ㎍/ml of CM and/or PJ. B lymphocytes subpopulation in splenocytes were increased both CM and/or PJ administered(p.o. for 7 days)-mice. Thymic T lymphocytes, especially TH cells were significantly increased in CM-administered mice. CM and/or PJ treatment inhibited the cell viability of L 1210 mouse leukemia and HL60 human leukemia cells and induced the apoptosis of L1210 and HL60 cells. In addition, CM and/or PJ increased the hemaggutination(HA) titer against SRBC. These results suggest that CM and/or PJ have an immuno-modulatory action and anti-carcinogenic property.

To investigate the anti-proliferative effects of an aqueous extract of Cordyceps militaris (AECM) on the growth of human lung carcinoma cell line A549, we performed various biochemical experiments such as the effects of AECM on the cell proliferation and viability, the morphological changes, the effects on expression of apoptosis and cell growth-regulatory gene products. Results obtained are as follow; AECM treatment declined the cell viability and proliferation of A549 cells in a concentration-dependent manner. The anti-proliferative effect by AECM treatment in A549 cells was associated with morphological changes such as membrane shrinking and cell rounding up. Taken together, these findings suggest that AECM-induced inhibition of human lung cancer cell proliferation is associated with the induction of apoptotic cell death via regulation of several major growth regulatory gene products, and C. militaris may have therapeutic potential in human lung cancer.
