Methods: Liver injury models of mice were made by using CCL 4, then levels of serum ALT, AST, Alb and A/G were determined by biochemical method, The histological changes were observed with light and electron microscopy.

• 方法 :采用 CCl4 复制小鼠肝损伤模型 ,测定血清丙氨酸氨基转移酶 (AL T)、天门冬酸氨基转移酶 (AST)、白蛋白 (Alb)、计算 A /G比值 ,并采用光镜、电镜观察组织学变化。
