Abstract:

Mice with acute liver injury were modeled through CCl4 induction and orally administered with soybean polypeptides at doses of 3, 1.8 and 0.6 g/kg·d for 30 d, respectively. Effects of soybean polypeptides on glutamic-oxaloacetic transminase (GOT), glutamic-pyruvic transminase (GPT) and alkaline phosphataes (ALP) in serum and triglyceride (TG), total cholesterol (TC), malondialdehye (MDA) and glutathione peroxidase (GSH) levels in liver were investigated. Results indicated that CCl4- induced mice model with liver injury was successfully established. Soybean polypeptides significantly decreased the levels of GOT, GPT and AST in serum and TG, TC and MDA in liver, and obviously increased the level of GSH in liver in a dosedependent manner. Therefore, soybean polypeptides have an excellent protective capability against acute liver injury in mice induced by CCl4.

Key words: soybean polypeptides, liver injury, GPT, GOT, ALP, MDA, GSH
