These indicates bioactive peptides in Chinese forest frog skins have great potential for the exploitation and utilization. S_(180) cells were inoculated hypodermically at the concentration of 1×10~6 cells per mouse and the bioactive peptides in Chinese forest frog skins were resolved into aseptically distilled water to make injection liquid. After injected continuously 15 days, the inhibition rate of tumor was calculated. The induction of tumor cell apoptosis of active peptides in Chinese forest frog skins could be detected by morphological
