中文摘要：

目的：考察甘草对黄药子引起的肝损伤的CYP450酶基因表达的影响。方法：采用逆转录聚合酶链反应（RTPCR）技术检测大鼠肝脏CYP1A2、CYP2C19的mRNA的表达。结果：在mRNA水平上,28天、35天黄药子组均显著诱导CYP1A2的基因表达,配伍甘草后表达降低,具有统计学意义。甘草组可微弱下调CYP2C19的表达,但与配伍组相比无统计学意义。结论：甘草通过抑制CYP1A2的mRNA表达,对黄药子致肝损伤具有一定保护作用。

英文摘要：

Objective： To study the effects of the compatibility of Huangyaozi and Gancao on the CYP450 mRNA expression in rat livers. Method： The mRNA levers of the expression of the CYP 1A2 and CYP2C 19 gene of the rat liver were assayed with RT-PCR. Result： The mRNA levels of CYP1A2 were induced significantly by group of Huangyaozi after medication for 28 days and 35 days separately and reduced after given the compatibility with Gancao. Conclusion： The mRNA expression of CYP1A2 was inhibited by Gancao to protect liver from injury which caused by Huangyaozi.
