摘要: 为研究妊娠期肝内胆汁淤积症,将妊娠第15天的清洁级SD大鼠20只,随机分成2组,实验组皮下注射17α乙炔雌二醇(EE,2.5mg/kg·d×5d,溶于丙二醇),对照组注射丙二醇。结果,实验组血清中的丙氨酸转氨酶、天冬氨酸转氨酶和总胆酸较给药前显著升高(P<0.05),胆固醇显著下降(P<0.05),碱性磷酸酶含量无显著改变;肝细胞有空泡变性和坏死,肝内毛细胆管内有胆栓形成。提示EE可诱发孕鼠肝内胆汁淤积。

Abstract: To study the effects of ethynylestradiol (EE) on the biochemical parameters and hepatic tissue in pregnant rats,the pregnant rats were injected with EE(2.5 mg/kg • d,dissolved in propylene glycol,lg/L,n=10) or vehicle (n=10) subcutaneously from the 15th to 19th day of gestation. The serum levels of ALT, AST, ALP,TBA and CHO were measured before and after the treatment. The livers were examined histologically after the treatment. The results showed that significantly increasing in levels of ALT, AST and TBA accompanied by intrahepatic cholestasis was found in the experimental rats,while no alterations were found in the control rats. These alterations induced by EE are similar to those of intrahepatic cholestasis of pregnancy in women.
