【摘要】 目的观察紫红獐牙菜总提物对几种物质诱导小鼠肝损伤的保护作用。方法采用CCl4及BCG/LPS造成小鼠肝损伤,并测定小鼠血清丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)和肝组织丙二醛(MDA)的含量,同时观察肝组织病理改变。结果紫红獐牙菜总提物能明显降低由CCl4引起的小鼠ALT、AST的升高,缓解肝组织病理变化,减轻肝脏水肿。而对BCG/LPS所致小鼠血清ALT、AST的升高无明显降低作用,但能降低MDA及肝脏和脾脏指数,也能缓解肝组织病理改变。结论紫红獐牙菜总提物具有一定保肝降酶及抗氧化作用,对CCl4肝损伤的保护作用比对BCG/LPS性肝损伤的保护效果好。更多还原

【Abstract】 Objective: to observe the protective effect of Swertia Punicea on experimental hepatic injury induced by CCl4 and BCG/LPS respectively. Methods: Mouse models of hepatic injury were induced by CCl4 and BCG/LPS. Serum levels of ALT and AST, MDA content and the pathological changes of hepatic tissue were observed. Results: Swertia Punicea obviously inhibited the rising levels of serum ALT and AST, improved the histological features and relieved hepatic edema induced by CCl4 in mice. However, it has no obvious action on the rising levels of ALT and AST induced by BCG/LPS. It also reduced MDA content and decreased the hepatic index and the splenic index. Conclusion: Swertia Punicea has antioxidation and a protective action on the chemical and immunological hepatic injury, especially on the chemical hepatic injury.更多还原
