目的:探讨加味四君子汤对脑缺血大鼠脑组织闭合蛋白(Occludin),密封蛋白-1(Claudin-1),闭锁连接蛋白-1(ZO-1)表达的影响,并探讨相关的作用机制。方法:将60只雄性SD大鼠随机分为假手术组,模型组,依达拉奉组(3.2×10~(-3) g·kg~(-1)),加味四君子汤加减低、中、高剂量组(4.77,9.54,19.08 g·kg~(-1))。采用线栓法制备大脑中动脉栓塞(MCAO)模型,治疗7 d后处死,运用蛋白免疫印迹法(Western blot)检测大鼠缺血侧脑皮质区Occludin,ZO-1,Claudin-1蛋白的表达,运用实时荧光定量聚合酶链式反应(Real-time PCR)检测大鼠缺血侧脑皮质区Occludin,ZO-1,Claudin-1 mRNA表达。结果:与假手术组比较,模型组Occlud...

Objective: To investigate the effect of modified Sijunzi Tang on protein and mRNA expressions of Occludin, Claudin-1 and zonula occludens-1(ZO-1) in cerebral ischemia rats. Method: Totally 60 male Sprague-Dawley rats were randomly divided into sham operation group, model group, edaravone group, small-dose modified Sijunzi Tang group, middle-dose modified Sijunzi Tang group and high-dose modified Sijunzi Tang group. The middle cerebral artery occlusion (MCAO) model was prepared by suture method. After 7 days of treatment, the modeling group was put to death. Western blot was used to detect the ...
