目的:探讨红背叶根抗肝纤维化的作用机理。方法:建立四氯化碳(CCL4)复合因素肝纤维化大鼠模型,观察红背叶根对模型动物转化生长因子β1(TGFβ1)、基质金属蛋白酶组织抑制因子1(TIMP-1)的影响。结果:红背叶根能显著抑制大鼠血清中的TGFβ1、TIMP-1、透明质酸酶(HA)、层粘连蛋白(LN)、Ⅲ型前胶原(PCⅢ)、Ⅳ型胶原(CIV)、谷丙转氨酶(ALT)、谷草转氨酶(AST)的表达。姑论:红背叶根对肝纤维化形成中两个重要因子TGFβ1和TIMP-1表达的抑制作用,可能是其抗肝纤维化的作用机理之一。
Objective: To explore the mechanism of Hongbeiyegen' s resistive effects on hepatic fibrosis. Methods : Rat fibrosis models were established by CCl4 compound factors. Transforming growth factor β1 (TGFβ1) , tissue inhibitor of metalloproteinase - 1 ( TIMP - 1 ) were detected in the serum among the different groups. Results : Hongbeiyegen could reduce the serum level of TGFβ1, TIMP - 1, Hyaluronic Acid (HA), Laminin ( LN ), Procolagen Type Ⅲ ( PC Ⅲ ), Collagen Type Ⅳ ( C Ⅳ ), glutamic - pyruvic transaminase(ALT) and glutamic -oxalacetic transaminase (AST) respectively. Conclusion: Hongbeiyegen can inhibit the expression of TGFβ1 and TIMP - 1, the two main factors related to the occurrence of hepatic fibrosis. This may be one of the mechanisms which Hongbeiyegen restrains the progression of liver fibrosis.
