摘要
目的:观察藤茶总黄酮(Tengcha flavonoids,TCF)对大鼠肝纤维化的防治作用。方法:66只雄性SD大鼠被随机分为5组:正常对照组(10只),正常喂养;模型组(14只):采用四氯化碳(CCL4)皮下注射诱导大鼠肝纤维化模型;TCF治疗组分为低、中、高剂量组(每组14只):在造模的同时,每日分别予以TCF25mg/100g、50mg/100g、100mg/100g体重灌胃。于第12周末检测血清谷丙转氨酶(ALT)、谷草转氨酶(AST)、透明质酸(HA)、层粘连蛋白(LN)、Ⅲ型前胶原(PCⅢ)、Ⅳ型胶原(CⅣ)的水平以及肝组织中超氧化物歧化酶(SOD)活性、丙二醛(MDA)的含量变化。结果:与模型组比较,TCF各剂量组血清中ALT、AST、HA、LN、PCⅢ、CⅣ的水平显著下降(P<0.05);SOD活性明显增高,MDA的含量明显降低(P<0.05)。结论:TCF对CCL4实验性肝纤维化大鼠有较好的防治作用,其作用机制可能与抗氧化、抗脂质过氧化有关。
