摘要:

采用CCl4 灌胃造成小鼠急性肝损伤模型,将大豆多肽分为高、中、低剂量组,分别为3、1.8、0.6g/kg·d喂饲小鼠30d,观察其对血清GPT、GOT 和ALP 及肝脏TG、TC、MDA 和GSH 的影响。实验结果表明:成功建立小鼠急性肝损伤模型,与模型组比较,大豆多肽可显著降低血清中GOT、GPT 和ALP 活性和肝脏TG、TC和MDA 含量,提高肝脏中GSH 含量,以高剂量组效果最佳,呈明显的剂量依赖性。大豆多肽对CCl4 引起的小鼠急性肝损伤具有保护作用。

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
