The mice feed on common food with the biological preparation of A CM after inoculation with sarcocarcinoma S180 and their survival days and weights of sarcocarcinoma and bodies are examined at tenth day. Results show the life span of mice in both groups of low dosage (20g/kg) and high dosage (100g/kg) are 7.6% and 21.9% longer than that in the control group. Comparing with control group, the inhibition mice of sarcocarcinom for both groups are 8.7% and 28.1% respectively. Examination of mice body weight i...
