Objective: Study on antitumor activity of Qilongyi Capsules

and its influence to SOD and MDA in serum of tumor-bearing mice. Method: Used models of human gastric cancer BGC-823

tumors S180

liver cancer H22 ascites tumors.And used the methods of Qilongyi Capsules which were divided into three groups

hig

middle and low. Result: The Qinglongyi Capsules had remarkable affects at suppressing tumor

its inhibition rate on the tumors over 68.1%(P<0.01) to tumor-bearing nude mice and over 61.2%(P<0.01) to tumor-bearing mice

can significantly increase SOD levels(P<0.05) and lower MDA level(P<0.05)

and the life span was increased to 86.6%(P<0.01) for mouse with H22 and solid tumors. Conclusions: Through the experiments we can prove that Qilongyi Capsules has remarkable antitumor activity.
