摘要： 目的研究香加皮水提组分和醇提组分多次给药致小鼠肝毒性的“量- 时- 毒”关系。方法取小鼠按不同时间点或不同剂量分组，观察小鼠死亡情况和毒性反应，分别于药后相应时间点检查血清肝功指标和肝脏组织ALT、AST活性，计算肝、肾脏器指数。结果香加皮水提组分和醇提组分对小鼠多次给药肝毒性“量- 时- 毒”关系研究为：ALT、AST在给药后1天明显升高，以AST 为更敏感，一直持续到7天。药后7 天之内，水提组分在（0.78~15.0）g·kg-1剂量范围之内、醇提组分在（0.78~6.0）g·kg-1 剂量范围之内，与正常组比较，香加皮水提和醇提组分均可造成明显的肝毒性损伤，表现ALT、AST、ALP、TBI 升高，ALB 降低，肝体和肾体比值有不同程度的增高，呈现明显的量效和时效关系;且醇提组分的肝毒性作用程度>水提组分。结论多次给小鼠一定剂量的香加皮水提组分和醇提组分均可造成明显的肝损伤，并呈现明显的肝毒性“量- 时- 毒”关系。

Abstract: Objective To study the "dosage-time-toxicity" relationship of hepatotoxicity induced by multiple intragastric administration of water extracted and alcohol extracted components of Cortex Periplocae to mice. Methods Mice are grouped according to different time or dose points, the general condition and toxic effects of mice were observed.The changes of the activity of ALT, AST, etc and liver, kidney index were detected. Results On the first day after administration the hepatotoxicity which displayed with obvious increase of activity in serum ALT, AST, especially the changes of AST were more sensitive. The conditions continued for about 7 days. Compared with the normal group, within 7 days after the administration, water extracted components in(0.78~15.0) g·kg-1 doses of scope, alcohol extracted components in(0.78~6.0) g·kg-1 doses of scope, they all cause significant damage to liver, the activity of ALT, AST, ALP, and TBI elevated, while ALB reduced, and liver ratio increased, it shows there were obvious "dosagetime-toxicity" relations. The degree of hepatotoxicity damage caused by the alcohol extracted composition is more serious than that by the water extracted composition. Conclusion Multiple intragastric administrations of water extracted and alcohol extracted components of Cortex Periplocae with certain dosage may induce acute hepatotoxical injury in mice and show an obvious "dosage-time-toxicity" relationship.
