伤寒头对CCl_4致小鼠急性肝损伤的保护作用及其机理

本研究将健康昆明种小鼠36只,雌雄各半,随机分为空白对照组、模型组、药物联苯组、伤寒头高剂量、中剂量及低剂量组。各分组连续给药3d,末次给药1h后,除正常对照组外,其余各组腹腔注射1%CCl4花生油溶液0.1mL/10g建立小鼠急性肝损伤模型。测试小鼠禁食24h后,摘眼球取血并处死动物,分离血清进行血清生化指标的测定,检测小鼠血清中门冬氨酸氨基转氨酶(AST)、丙氨酸氨基转氨酶(ALT)、白蛋白(ALB)和总蛋白(TP)水平;剖检并取肝脏组织测肝脏重量,取部分肝组织研磨成匀浆测定超氧化物歧化酶(SOD),丙二醛(MDA)和谷胱甘肽过氧化物酶(GSH-PX)。观察伤寒头处理下小鼠血清中AST、ALT、ALB和TP以及肝脏中SOD、MDA和GSH-PX的变化。结果表明,各伤寒头治疗组对AST、ALT均有明显的降低作用(P<0.01),对TP、ALB没有影响(P>0.05);各伤寒头治疗组对SOD和GSH-PX有升高作用(P<0.05),对MDA有降低作用(P<0.05),对肝脏指数没有影响(P>0.05)。根据本研究结果,我们推断伤寒头对四氯化碳所致小鼠急性肝损伤具有明显的保护作用,主要是通过提高SOD和GSH-...

Hepatoprotective Effects and Mechanism of Herb of Shanghantou on the CCl_4-induced Acute Live Injury in Mice

In the experiment, male and females with equal quantity, 36 animals, Kunming mice, were randomly divided into 6 groups by weight such as control group, model group, drug positive group, Herb of Shanghantou high dose, middle dose and low dose groups. Every grouping successive administration for 3 d, 1 h after the last administration, in addition to the normal control group, the remaining groups were injected 1% CCl4 peanut oil so-lution 0.1 mL/10 g, to establish the model of acute liver injury in mice.
