舒肝安乐宁浸膏对小鼠急性酒精性肝损伤保护作用的研究

目的研究舒肝安乐宁浸膏对小鼠急性酒精性肝损伤的保护作用。方法以白酒灌胃法建立小鼠急性酒精性肝损伤模型,观察血清丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、肝组织中超氧化物歧化酶(SOD)、丙二醛(MDA)、甘油三酯(TG)指标的变化,并进行病理组织学检测。结果各剂量舒肝安乐宁浸膏能显著降低小鼠血清ALT、AST活性和肝组织MDA、TG含量(P<0.05或P<0.01),提高肝组织SOD活性,减轻肝脏的病理损伤。结论舒肝安乐宁浸膏对急性酒精性肝损伤有保护作用。其作用机制可能为减少自由基的产生,抑制脂质过氧化反应,减少脂肪在肝脏的沉积。

Protective effect of Shugananlening extract on acute alcohol hepatic injury in mice

Objective To study the protective effect of Shugananlening extract on acute alcoholic hepatic injury in mice. Methods The model of hepatic injury was prepared by intragastric infusion of alcohol, the change of alanine transaminase (ALT), aspartate transaminase (AST) in serum and liver superoxide dismutase (SOD), malondialdehyde (MDA) and triglyceride (TG) were observed. HE staining was used to observe the pathological changes in liver. Results The level of ALT, AST, TG and MDA were significantly reduced and the activity of SOD was enhanced by different doses of Shugananlening Extract. Furthermore, the pathological injury was also significantly abated by high-dose and middle-dose of Shugananlening Extract. Conclusion Shugananlening extract had a good protective effect on acute alcoholic hepatic injury in mice. The mechanisms probably contributed to the decrease of lipid peroxide and fatty sediment in liver.
