摘要
为研究芍药苷对四氯化碳(CCl4)诱导的急性肝损伤的保护作用及相关机制。将36只健康雄性C57BL/J小鼠随机分成6组:空白组,芍药苷对照组,CCl4模型组(0.1%,20 mL/kg),高、中、低剂量芍药苷+CCl4组(10 mg/kg,30 mg/kg,100 mg/kg),每组6只。24 h后眼球取血收集血清,测定丙氨酸氨基转移酶(ALT),天门冬氨酸氨基转移酶(AST)活性。用苏木精-伊红(HE)染色,观察肝脏的组织学改变;试剂盒测定肝组织中SOD、GSH-PX、CAT的活性及MDA和GSH含量;ELISA法检测血清中TNF-α、IL-6含量;试剂盒检测小鼠肝组织中Caspase-3的活性;q RT-PCR检测肝组织中HO-1 mRNA的表达。实验发现PAE降低小鼠血清ALT、AST水平,改善肝脏的病理形态;芍药苷抑制CCl4诱导氧化应激,升高肝组织HO-1 mRNA水平;降低TNF-α、IL-6含量;芍药苷减低肝组织中Caspase-3活性,减少肝细胞凋亡。由此可知,芍药苷可保护CCl4诱导的急性肝细胞损伤,该保护作用可能与抑制脂质过氧化,减少促炎细胞因子产生,减少肝细胞凋亡,促进抗氧化蛋白表达有关。
