目的观察丹龙醒脑方对脑缺血再灌注模型大鼠侧脑室室管膜下区(SVZ)神经干细胞(NSCs)增殖与Hes1、Hes5表达的影响,探讨其促进内源性NSCs增殖的作用机制。方法将80只雄性SD大鼠随机分为假手术组、模型组、依达拉奉组(依达组)、丹龙醒脑方组(丹龙组)。采用线栓法制备局灶性脑缺血再灌注模型,再灌注7 d后取缺血侧SVZ脑组织。Brdu免疫荧光法检测SVZ NSCs增殖,RT-qPCR、Western blot分别检测Hes1、Hes5 mRNA和蛋白的表达。结果与假手术组比较,其余各组Brdu阳性细胞率增加,Hes1、 Hes5 mRNA及蛋白表达明显升高(P

Objective To study effects ofDanlong Xingnao Formula (DLXNF) on proliferation of neural stem cells (NSCs) and the expressions of Hes1 and Hes5 in sub ventricular zone (SVZ) in cerebral ischemia-reperfusion injury model rats; To explore the mechanism of promoting the proliferation of NSCsMethods Eighty male SD rats were randomly divided into sham-operation group, model group, edaravone group andDLXNF group. The focal cerebral ischemia reperfusion injury models were prepared by suture method, and 7 d after reperfusion, the SVZ brain tissue of ischemia side was taken. The proliferation of cells w...
