摘要 摘要 :目的 :探讨中药复方肝力克对肝纤维化大鼠肝组织基质金属蛋白酶抑制物 2(TIMP 2 )mRNA表达的影响。方法 :用 4 0 %CCl4皮下注射建立SD大鼠肝纤维化模型。造模结束后 ,给予不同剂量的肝力克和秋水仙碱灌胃治疗 9周。采用原位杂交法观察大鼠肝组织中TIMP 2mRNA的表达情况。结果 :肝纤维化模型组大鼠肝组织TIMP 2mRNA阳性表达较正常对照组明显升高 (P <0 0 1) ;应用肝力克大、中、小剂量治疗后 ,大鼠肝组织TIMP 2mRNA表达明显降低 (P <0 0 5 ) ,而秋水仙碱组则无显著变化 (P >0 0 5 )。结论 :TIMP 2是影响肝纤维化形成的重要因素 ,肝力克下调肝纤维化大鼠肝组织TIMP 2mRNA表达 ,可能是其抗肝纤维化作用机理之一。
