摘要
目的研究促肝细胞生长素对异烟肼和利福平诱导大鼠肝损伤的保护作用。方法雄性SD大鼠给予异烟肼50mg/kg+利福平100 mg/kg,建立肝损伤模型。促肝细胞生长素组在模型组的基础上给予促肝细胞生长素肠溶胶囊40 mg/kg,给药3周后,称体质量,计算肝系数,同时比较血清肝功能指标丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、碱性磷酸酶(ALP)、总胆红素(TBIL)和直接胆红素(DBIL),肝抗氧化酶系超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、还原型谷胱甘肽(GSH)和丙二醛(MDA)水平,切片观察肝脏病理变化。结果与模型组相比,促肝细胞生长素组ALT、AST显著降低(P<0.05),ALP、TBIL和DBIL水平也表现出明显的降低趋势;肝组织SOD、GSH-Px水平显著升高(P<0.05),MDA水平显著降低(P<0.05),GSH水平有升高趋势。促肝细胞生长素组肝小叶结构清晰,炎症细胞浸润减少。结论促肝细胞生长素对异烟肼和利福平诱导肝损伤具有保护作用,其作用机制可能与其肝再生增强因子提高肝组织抗氧化能力、抑制肝组织炎症反应有关。
