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 study was carried out to measure the antitumor effect of traditional doenjang (Korean soybean paste) added with Japanese apricot, garlic or ginger. Four kinds of traditional doenjang inhibited significantly the tumor growth in mice injected sarcoma-I80 cells. Especially, traditional doenjang added with ginger (Gi-TD) showed an inhibition of tumor cell activity of 97% by the administration of 1.0 mg/kg methanol extracts. Among Balb/c mouse administered doenjang extracts, the liver weight of mice fed Gi-TD was heavier than that of the group not administered doenjang. However, no difference was found between the control and doenjang administrated groups in weights of body, spleen, kidney and heart. The activity of natural killer (NK) cells was relatively high in mice administrated with the four kinds of doenjang. Particularly, mice administrated with the Gi-TD methanol extracts showed a strong activity of 82.9%. The activity of glutathione S-transferase (GST) in mice administrated with the 4 kinds of doenjang was higher than that of the group not administered with doenjang. In particular, the GST activity was the strongest in the group administrated with Gi-TD. The results suggest that Gi-TD has a strong growth inhibition activity against sarcoma-180 tumor cells.

A hot water extract(HWE-P4) was separated from the fruit bodies of PMO-P4, and its antitumor and immunomodulatory activities against sarcoma-180 in ICR mice were investigated. The internal transcribed spacer(ITS) regions from PMO-P4 were amplified using polymerase chain reaction(PCR) and sequenced. The results revealed that PMO-P4 was belong to the Phellinus baumii. When oral administration at the dose of 160mg/kg/day in the mice until the end of the experiment with 2 week's pre-feeding of the HWE-P4, the survival rate of the mice was 152% for 50days after the inoculation of sarcoma-180 and the suppression rate of the tumor growth was 35.3%(p<0.05) for 28 days after inoculation of sarcoma-180. The HWE-P4 increased 71.4% of the CD4/CD8 ratio and 5-fold of the expression of CD25(IL-2 receptor chain) compared with the control. From these results, the antitumor activity of HWE-P4 is exerted through its immunomodulating activity on the host's immune system.

Phellinus linteus was examined for its anticancer activity using an animal model. Water extract of Phellinus linteus was prepared from artificially cultivated mycelia. Neither toxicity nor abnormal changes of hematological parameters were observed in the rat given orally with high doses of drug extract for 15 days. ICR mice were transplanted with Sarcoma-180 tumor cells intraperitoneally and drug extract was daily given to the mice from 1 day after tumer transplantation for 3 weeks. Administration of drug extract significantly prolonged the survival duration of Sarcoma 180-transplanted mice. For the better understanding of the anticancer activity, we have examined the effect of the drug extract administration on various killer cell functions, such as natural killer(NK) cells, cytotoxic T-lymphocytes (CTL) and macrophages which have been known to be main effector cells in immune responses against tumors. The results from the 4 hr $^{51}Cr-release$ assay have shown that the drug extract augments mouse NK cell activity but neither CTL nor macrophages. It is possible, then, that the anticancer activity of the Phellinus linteus may be associated with augmentation of NK cell function in the cancerated hosts.
