1、电针对海洛因依赖大鼠海马神经细胞凋亡的影响姓名:2014年6月25日电针对海洛因依赖大鼠海马神经细胞凋亡的影响【摘要】目的:观察海洛因依赖大鼠海马细胞凋亡情况及电针的干预作用,为针刺戒毒提供一定的理论依据。方法:SD大鼠24只随机分为对照组和实验组;实验组按剂量逐日递增原则,每日2次、连续9天皮下注射海洛因,第10天用纳洛酮催促戒断,建立海洛因依赖模型,再经跳台实验测试筛选,分为电针组和非电针组,每组8只动物;非电针组继续给予海洛因维持剂量,电针组停止给药,处于自然戒断状态,同时选取“百会”、“大椎”进行电针治疗,每天1次,连续7天;采用TUNEL法、Envision免疫组化法
2、检测3组大鼠海马区细胞凋亡情况及凋亡相关蛋白Bcl-2、Bax的变化。结果:与对照组比较,非电针组大鼠海马细胞凋亡指数显著升高(P0.01),Bcl-2蛋白表达降低(P0.01),Bax蛋白表达增加(P0.01);与非电针组比较,电针组大鼠海马IX细胞凋亡指数显著降低(P0.01),Bcl-2蛋白表达增加(P0.01),Bax蛋白表达降低(P0.01)。结论:电针促进Bcl-2表达、抑制Bax表达,可加速细胞修复、保护损伤脑组织、改善海洛因依赖大鼠学习记忆能力。【关键词】海洛因依赖;细胞凋亡;海马;电针TheEffectofElectroacupunctureonApoptos
