摘　　要：目的:研究谷胱甘肽复方注射液(CGII)治疗猪血清致大鼠免疫性肝纤维化的药效作用。方法:建立猪血清诱导免疫性肝纤维化模型,全自动生化仪检测血清中丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、白蛋白(A)及球蛋白(G)水平;酶免法检测血清中透明质酸(HA)的含量;称取肝脏湿重,计算肝脏指数;消化法检测肝组织羟脯氨酸(Hyp)含量;苏木素-伊红(HE)及Masson染色处理肝脏组织切片;光镜观察病理学改变。结果:在猪血清诱导的大鼠肝纤维化模型中,所有剂量水平的CGII(2.7,5.4,10.8 mg.kg-1,im)能显著降低大鼠血清ALT,AST,A/G值和HA水平;中、高剂量CGII(5.4,10.8 mg.kg-1,im)能显著降低大鼠肝组织Hyp含量,明显改善肝脏病理组织状况;高剂量CGII(10.8 mg.kg-1,im)能显著降低大鼠肝脏指数。结论:CGII对猪血清致大鼠肝纤维化有治疗作用。Objective： To study the therapeutic effect of compound glutathione inosine injection（CGII） on liver fibrosis immunologically induced by porcine serum in rats.Methods： The liver fibrosis was induced by intraperitoneal injection of porcine serum.The serum activities of alanine aminotransferase（ALT）,aspartate aminotransferase（AST）,albumin（A） and globulin（G） were assayed by automatic biochemistry detection instrument.The serum haluronic acid（HA）,a hepatic fibrosis index,was determined by ELISA method.Liver index was calculated;hydroxyproline（Hyp） content in liver tissue was assayed by alkaline hydrolysis colorimetry.The hepatic histological changes were also observed by optical microscopy after HE and Masson staining.Results： In rats with liver fibrosis,CGII（2.7,5.4,10.8mg·kg-1,im） significantly decreased the serum levels of AST,ALT,A/G and HA;CGII（5.4,10.8mg·kg-1,im） obviously improved the pathological lesion of liver fibrosis and decreased Hyp contents in liver;CGII（10.8mg·kg-1,im） also decreased liver index.Conclusion： CGII has a therapeutic effect on hepatic fibrosis immunologically induced by porcine serum in rats.
