The mushroom Cordyceps militaris has been used for a long time in eastern Asia as a nutraceutical and in traditional Chinese medicine as a treatment for cancer patients. In the present study, a cytotoxic antifungal protease was purified from the dried fruiting bodies of C. militaris using anion-exchange chromatography on a DEAE-Sepharose column. Electrophoretic analyses indicated that this protein, designated C. militaris protein(CMP), has a molecular mass of 12 kDa and a pI of 5.1. The optimum conditions for protease activity were a temperature of $37^{\circ}C$ and pH of $7.0{\sim}9.0$. The enzyme activity was specifically inhibited by the serine protease inhibitor phenylmethylsulfonyl fluoride. Amino acid composition of intact CMP and amino acid sequences of three major peptides from a tryptic digest of CMP were determined. CMP exerted strong antifungal effect against the growth of the fungus Fusarium oxysporum, and exhibited cytotoxicity against human breast and bladder cancer cells. These results indicate that C. militaris represents a source of a novel protein that might be applied in diverse biological and medicinal applications.

Cordyceps militaris specimens were continuously collected by Entomopathogenic Fungal Culture Collection (EFCC), Kangwon National University from different mountains, national parks and recreation parks of Korea from 1986 to 2002, mainly from late May to October of each year. Dry specimens of C. militaris along with their isolates have been preserved in EFCC. Fruiting of C. militaris was induced from single ascospore isolates as well as their combinations in brown rice medium. Fruiting experiments showed that combinations of single ascospore isolates produced fertile fruiting bodies, but single isolates could not produce any fruiting bodies. It was shown that two isolates of the opposite mating types were required to produce fertile stromata. However, combinations of the same mating type isolates produced no fruiting body, showing that C. militaris is a bipolar, heterothallic fungus.

Cordyceps militaris mycelium extracts containing high amounts of cordycepin were evaluated in vitro for their anti-inflammatory and tumor cell growth-inhibitory activities. All extracts dose dependently inhibited the increased production of inflammatory mediators including reactive oxygen species (ROS), nitric oxide (NO), and 𝛽-hexosaminidase in lipopolysaccharide (LPS)-stimulated inflammatory cells. All extracts were evaluated for anti-proliferative activity against normal RBL-2H3 cells and diverse types of cancer cell lines, including HCT, MC5-7, U-87MG, AGS, and A549 cells. The extract showed the strongest growth inhibition (IC₅₀ = 28.13 ㎍/mL) relative to vehicle-treated control cells against fibrosarcoma (MC5-7). We have demonstrated anti-inflammatory activity of C. militaris via inhibition of NO, ROS production, and 𝛽-hexosaminidase release in activated cells. C. militaris mycelium extract was also evaluated mechanistically and found to exert six types of anti-cancer activity, confirming its pharmacological potential. Our study suggests C. militaris use as a potential source of anti-inflammatory and anti-cancer agents. C. militaris may also be considered a functional food.

Objectives : This study was performed to investigate the effects of Cordyceps Sinensis (CS) and Cordyceps Militaris (CM) on anti oxidation in the livers of ${CCl_4}-treated$ rats. Methods : Hepatotoxicity in rats was induced by carbon tetracWoride. $CCl_4-induced$ rats were administered with the extract of CS and CM. Results : In vitro, CS and CM didn't affect levels of lipid peroxide and the activities and type conversion ratio of xanthine oxidase. However, hydroxyl radicals and DPPHL radicals were decreased. In vivo, in the ${CCl_4}-treated$ rats, lipid peroxide, the activities and type conversion ratio of xanthine oxidase and superoxide radicals were increased but superoxide dismutase was decreased. After CS and CM were administered to ${CCl_4}-treated$ rats, levels of lipid peroxide, the activities and type conversion ratio of xanthine oxidase and superoxide radicals were decreased but superoxide dismutase was increased. Conclusions : These results suggest that CS and CM decrease the activities of free-radical-generating enzymes which form lipid peroxide and increase the activities of oxygen free radical scavenging enzymes.

This study was performed to investigate the effects of taste-related compounds and antioxidatve profiles of retorted samgyetang made from fresh and dried Cordyceps militaris (C. militaris) mushrooms. A total of 48 carcasses were prepared from commercial broilers (CB; Ross, 4 weeks old) and randomly distributed into eight different treatments. Each treatment group consisted of 6 chicken carcasses made with the addition of broth in different condition and concentration of C. militaris mushrooms. The addition concentration was based on the broth volume (v/w) under either fresh or dried conditions ranging from 0% as a control to 1%, 2%, and 3% of C. militaris mushrooms. C. militaris mushrooms contributed to an improvement of meat tenderness and the antioxidative profile that led to a greater suppression of lipid oxidation. The addition of C. militaris mushrooms at 2% could also enrich the flavor and taste-related compounds, particularly the increase in 5'-AMP and umami-related free amino acid compounds, L-aspartic acid and L-glutamic acid. Different addition forms of C. militaris mushrooms, particularly fresh or dried mushrooms, had only small effects on bioactive compounds, where the dried addition could possibly enrich samgyetang broth with higher cordycepin and adenosine contents than the fresh addition. Besides, the addition of C. militaris mushrooms in the dried form could also contribute to a higher antioxidative profile. Eventually, the addition of C. militaris mushrooms with a minimum addition of 2% contributed to an improvement of meat quality, antioxidative profile and flavor improvement of samgyetang.

본 연구에서는 면역억제 동물모델에서 밀리타리스 동충하초 50% 에탄올 추출물의 면역력 증강 기능을 평가하였다. 이를 위하여 C57BL/6 마우스에 cyclophosphamide를 2회 복강주사 하여 면역력을 억제한 후, 밀리타리스 동충하초 추출물을 30, 100, 300 mg/kg 용량으로 12일간 경구투여 하였다. 마우스를 희생하여 몸무게 및 면역장기 무게, 비장세포의 증식, 비장세포의 cytokine 분비능, NK 세포 활성을 측정하였다. 그 결과, cyclophosphamide 투여에 의한 면역억제는 마우스의 몸무게와 간의 무게에 영향을 주지 않았으나 흉선의 무게는 감소시켰고 비장의 무게는 증가시켰다. 밀리타리스 동충하초 추출물 투여는 마우스의 몸무게 및 면역장기 무게에 영향을 주지 않았다. Cyclophosphamide 투여는 비장세포의 증식능을 감소시켰으며 밀리타리스 동충하초 추출물은 용량 의존적으로 비장세포 증식을 증가시켜 실험에 사용한 전 용량에서 비장세포의 유의적인 증식효과를 보였다. 비장세포의 cytokine 분비능을 측정한 결과, 밀리타리스 동충하초 추출물 투여는 IL-2, IL-12, IFN-${\gamma}$, TNF-${\alpha}$ 같은 Th1 cytokine의 분비를 대조군에 비해 유의적으로 증가시켰으나, IL-4와 IL-10 같은 Th2 cytokine의 분비에는 영향을 미치지 않았다. 또한 cyclophosphamide는 NK 세포의 활성을 정상군에 비하여 유의적으로 감소시켰으며, 밀리타리스 동충하초 추출물 투여는 cyclophosphamide에 의해 저하된 NK 세포 활성을 현저하게 증가시켰다. 이상의 결과를 종합해 볼 때, 밀리타리스 동충하초는 면역력이 억제된 상황에서 면역력을 증강시키며, 이러한 면역력 증강 효과는 체액성 면역보다 세포성 면역력 증강에 기인하는 것으로 보인다.

This study was undertaken to evaluate the antitumor activities of Cordyceps militaris of silkworm pupa (CMP) and silkworm larva (CML), as compared with the effect of cordycepin, an active compound found in Cordyceps militaris. Antiproliferation effect of the test materials were evaluated in the sarcoma-180 cells using the MTT test. For the in vivo study, ICR mice were inoculated i.p. with 1.0 ${\times}$ 10$^{6}$ sarcoma-180 cells/mouse on Day 0, and were again i.p. injected with one of the following substances from Day 1 to Day 10 : saline (control group), 50 mg/kg (CMP50, CML50) ,100 ma/kg (CMP100, CML100), or 200 mg/kg (CMP200, CML200) of Cordyceps militaris water extracts, or 1 mg/kg (C1), 2 mg/kg (C2), or 4 mg/kg (C4) of cordycepin. Pretreatment of the sarcoma-180 cells with 100 mg/ml, 500 mg/ml, and 1000 mg/ml of CML (60.1$\pm$2.5％, 49.8$\pm$3.7％, and 45.4$\pm$0.1％ of the value for untreated control cells, respectively) or CMP (68.3$\pm$2.1％, 55.1$\pm$0.9％, and 51.4$\pm$3.5％ of the value for control cells, respectively) for 48 hrs significantly decreased the survival rate (proliferation) of tumor cells (p<0.05). Body weight of the control mice bearing ascites tumor and injected with saline was 1.4 times of the value for normal animals at day 18. Mice bearing ascites tumor and injected with cordycepin (1, 2, or 4 mg/kg) exhibited a significantly lighter body weight compared with the control mice, while animals injected with CMP or CML (50, 100, or 200 mg/kg) showed a significantly lighter body weight compared with the mice injected with cordycepin. Mice injected with CMP50, CMP100, or CMP200 mg/kg (or CML50, CML100, or CML200 mg/kg) showed a 133％ (or 90％), 80％ (or 62％), and 68％ (or 52％) longer mean survival time, and those treated with C1, C2, or C4 exhibited a 54％, 91％ and 80％ longer survival time compared to the value for control mice injected with saline. These results indicate that the hot-water extracts of Cordyceps militaris of both silkworm pupa and silkworm larva have an anti-proliferation effect of tumor cells as well as the life prolongation effect in mice bearing ascites tumor, which are superior to the activities of cordycepin.

The effects of fruiting body of Cordyceps militaris on the growth, the food intake, the food efficiency ratio, the lipid metabolism, the serum protein level ad enzyme activity in male rats were studied. Sprague-Dawley rats were fed four types of diets for five weeks, respectiely: a control diet, a control diet supplemented with 2%, 3% or 4% fruiting body of Cordyceps militaris(CF) powder. In rats fed 2% or 3% CF diets the body weight gain, the food intake, the concentratons of hepatic triglyceride and serum LDL-cholesterol, the atherogenic index, and the total lipid, total cholesterol, triglyceride and phospholipid in serum were similar to those in rats fed the control diet. Whereas, in 4% CF diet these were significantly decrased. But the all CF diets feeding could not decrease the food efficiency ratio, the weights of liver, pancreas, spleen, kidney and heart, and the concentration of serum HDL-cholesterol. Also, it was shown that the concentrations of glucose, total protein, albumin, urea and creatinine, and the GOT, GPT, LDH, ${\gamma}$-GTP and ALP activities were the same levels in serum of rats of fed all the experimental diets.
