2、阴性纯合子小鼠9只为正常组。治疗组取双侧“心俞”“肾俞”行麦粒灸治疗,每日1次,10次为1个疗程,共治疗9个疗程。观察逃避潜伏期、穿越平台的次数及目标象限停留时间百分比来评价小鼠的学习记忆能力,刚果红染色法观察小鼠脑内AI?沉积的变化。结果:与正常组比较,模型组逃避潜伏期延长,穿越平台次数减少,目标象限停留时间百分比减少(P<0.05);模型组小鼠大脑额叶皮层和海马区呈现大小不一的At?沉积物。治疗后,治疗组小鼠学习记忆能力提高,与模型组小鼠比较,逃避潜伏期缩短,穿越平台次数增多,目标象限停留时间百分比增加(P<0.05);治疗组小
3、鼠大脑额叶皮层区和海马区AJ3沉积较模型组减少(P<0.05)。结论:麦粒灸疗法可显著改善APP/PS1转基因AD小鼠的学习记忆能力,其作用机制可能与有效抑制大脑额叶皮层区和海马区A8沉积有关。【关键词】麦粒灸APP/PS1转基因鼠淀粉样蛋白沉积学习记忆能力阿尔茨海默病【中图分类号】R245.81【文献标志码】A【文章编号】1000—0607(2014)01—0058—05EffectsofGrain—sizedMoxibustiononLearningandMemoryAbilityandAmyloidDepositionofTr
