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.
