摘要
目的观察茵陈总黄酮预先给药1周对急性肝损伤大鼠的保护作用。方法将大鼠分为空白对照组、模型对照组、茵栀黄口服液组和茵陈总黄酮小、中、大剂量组,均给药7 d。实验第6天,除空白对照组外,其他组大鼠腹腔注射D-半乳糖胺盐酸盐500 mg·kg-1。48 h后采血测丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)活性,检查肝脏病理特征。结果与模型对照组ALT[(391.9±181.3)U·L-1]和AST[(403.9±133.8)U·L-1)]比较,茵陈总黄酮大剂量组ALT和AST分别为[(189.2±112.9)U·L-1]和[(231.7±149.9)U·L-1],均显著降低。模型对照组肝细胞多发性碎片状坏死和脂肪变性分别为20和19只,而茵陈总黄酮大剂量组分别为1只和2只。与模型对照组比较,茵陈总黄酮各剂量组肝细胞出现多发性碎片状坏死、脂肪变性、炎细胞浸润和嗜酸性变性情况均不同程度减轻。结论茵陈总黄酮对急性肝损伤大鼠具有保护作用。
Objective To investigate the protective effect of total flavones of Artemisia capillaris Thunb.on acute hepat-ic injury in rats. Methods Rats were randomly divided into blank control group,model control group, Yinzhihuang group,and groups of total flavones of Artemisia capillaris Thunb.（low,medium and high dose） in terms of 7-day different treatments.All rats except those in the blank control group were administrated with D-galactosamine hydrochloride （ 500 mg-g-1 , ip ） once at the sixth day.Then,concentrations of ALT and AST were detected 48 h later,and the liver samples were collected from each group for pathological examination. Results The serum ALT and AST in high-dose group of total flavones of Artemisia capillaris Thunb. was [（189.2±112.9） and （231.7±149.9） U-L-1],respectively,significantly lower than those in model control group ALT [（391.9±181.3） U-L-1] and AST [（403.9±133.8） U-L-1].Fragmented necrosis,fatty degeneration,inflammatory cells infil-tration and acidophilic degeneration of hepatic cells were improved to varying degrees in groups of total flavones of Artemisia capil-laris Thunb.compared with model control group.Fragmented necrosis of liver cells and steatosis occurred in 20 and 19 rats,respec-tively,in the model control group,while those appeared in 1 and 2 rats,respectively,in high-dose group of total flavones of Artemi-sia capillaris Thunb.. Conclusion Total flavones of Artemisia capillaris Thunb. are effective in protecting D-galactosamine hydrochloride-induced acute hepatic injury in rats.
