摘要 目的:研究ERK信号通路在大鼠缺血再灌注脑组织的表达情况,并观察丹参酮ⅡA磺酸钠对其的调控作用。方法:建立大鼠脑缺血再灌注模型,应用免疫组织化学染色法检测缺血再灌注脑组织Ras,MEK,ERK阳性细胞数的表达,Tunel法检测神经细胞凋亡数量,观察Ras,MEK,ERK表达水平与神经坏死和凋亡的关系。结果:在缺血再灌注脑组织中Ras,MEK以及ERK表达均发生上调,给予REK抑制剂以及丹参酮ⅡA磺酸钠处理后,Ras,MEK以及ERK的表达均受到抑制,同时减少了细胞坏死和凋亡数量,与模型组相比均具有统计学差异(P<0.05)。结论:脑缺血再灌注后REK信号通路激活,丹参酮ⅡA磺酸钠可能通过抑制该通路的激活起到脑保护作用。
