The effects of mushrooms such as Lentinus edodes and Pleurotus ostreatus on anti-cancer activity through in vivo and in vitro experiments were powders of protein-bound polysaccharides in mushrooms were solubilized in 0, 5, 25 mg/kg saline, respectively and were used in vitro experiments. The in vivo experiments were carried out as followed: i) anti-cancer activities on Leukemia $(L_{1210})$, Hepatlicus cancer $(H_{22})$ and Sarcoma180/(S180), and ii) the effect on immune system through changes in intestine weight and the number of hemolytic plague forming cells. Protein-bound polysaccharides of all showed anti-cancer activity on $L_{1210}$ and fruit body of Lentinus edodes 25 mg/kg treatment group showed the highest inhibition rate (86%). Pleurotus ostreatus mycelial in medium of cultivate 25 mg/kg treatment. Fruid body of Lentinus edodes 25 mg/kg treatment group showed the highest inhibition rate (86% and 71%, respectively) on $H_{22}$ among them. The inhibition rates of fruit body and mycelial of Lentinus edodes 25 mg/kg treatment groups on S180 were 33.9% and 30.9%, respectively. Each samples of 50, 100, 200, $400\;{\mu}g/{\mu}L$ on in vitro cell toxicity test did not show significantly different cell death rates at P<0.05. In immune test, weights of liver and spleen were increased according to increase in conc. but were not significantly different at P<0.05. The weights of thymus were heavy in fruit body and mycelial of Lentinus edodes treatment group but were not significantly different at P<0.05. Hemolytic plague forming cells with antibody formation capability were significantly high in fruit body and mycelial of Lentinus edodes treatment samples.
