Methods Secretio bufonis injection (1.5 mL) was injected into the abdomind cavity of mice once 5 d for 3 times. Cyclophosphamide (0.5 mg/0.5 mL) was injected into other groups. NS (0.5 mL) was injected into control groups. Each group were 20 mice. TNF and survival time of mice were observed. Results Mean survival times of mice bearing intraperitoneal H22 tumor were (28.2±5.8)d for Secretio bufonis group, (27.9±9.7)d for Cyclophosphamide group, (20.7±4.2)d for control group. The content of TNF in mice bearing intraperitoneal H22 tumor were 2.53±0.14 for Secretio bufonis group, 3.02±0.14 for Cyclophosphamide group, 3.32±0.2 for control group. The survival times of mice bearing intraperitoneal H22 tumor were prolonged in the groups of Secretio bufonis (P<0.01) and Cyclophosphamide (P<0.05). The content of TNF were significantly inhibited in the groups of Secretio bufonis (P<0.01). Conclusion Secretio bufonis injection can inhibit the tumor and prolong the survival time of mice bearing intraperitoneal H22 tumor.
