摘要 目的:探讨NMDA受体亚单位NR2B特异性拮抗剂Ro25-6981对缺血再灌注大鼠脑室下区(SVZ)神经干细胞增殖的影响。方法:选取7d年龄新生SD大鼠并指作为缺血再灌注模型。采取随机数字表法均分为正常对照组、特异性拮抗剂组以及缺血再灌注组。统计各组间SVZ区Nestin表达量,同时记录BrdU阳性细胞数的上升下降情况。结果:12h,缺血再灌注组SVZ区Nestin阳性细胞的平均吸光度明显升高,与特异性拮抗剂组相比有明显差异(P<0.05)。24h等时间点特异性拮抗剂组与缺血再灌注组Nestin阳性细胞的平均吸光度明显变化较为一致。72h,缺血再灌注组BrdU阳性细胞数明显多于正常对照组以及特异性拮抗剂组,对比差异有统计学意义(P<0.05)。结论:Ro 25-6981能够降低缺血再灌注大鼠SVZ区Nestin表达量及BrdU阳性细胞数,表明其可调控神经干细胞增殖的表达,值得临床关注。
