摘要

目的:建立小鼠胆总管结扎致肝纤维化模型

并对其进行初步评价。方法:随机给予小鼠胆总管结扎和假手术

进行血清学指标（AST、ALT、ALP、TBIL、DBIL）检测;HE染色和天狼猩红染色进行形态学观察;采用免疫组化染色分析α-SMA和CK-19表达;实时荧光定量PCR检测α-SMA、Collagen-1 mRNA的表达。结果:小鼠胆总管结扎后2周可见CK-19阳性的棕褐色细胞明显增生

模型组血清AST、ALT、ALP、TBIL、DBIL明显增高

α-SMA、Collagen-1表达明显增强。结论:成功构建小鼠胆总管结扎致肝纤维化模型。

Abstract

Objective:To establish and evaluate liver fibrosis model induced by bile duct ligation in mouse.Methods:The bile ducts of the mice were occluded by ligation.Serum AST

ALT

ALP

TBIL and DBIL were determined;the morphological observation was done by HE staining and Sirius red staining

expressions of α-SMA and CK-19 were analyzed by immunohistochemistry staining;mRNA expression of α-SMA and Collagen-1 in liver tissues were assayed by real-time PCR.A sham-operation group was used as a control.Results:Chocolate brown cells with positive expression of CK-19 and α-SMA significantly proliferated 2 weeks after bile duct ligation.Serum AST

ALT

ALP

TBIL and DBIL levels of model group were much higher than those of control group;mRNA expression of α-SMA and Collagen-1 in liver tissue by real-time PCR were increased significantly in model group.Conclusion:The mouse liver fibrosis model can be established successfully by bile duct ligation.
