摘要 目的探讨糖尿病对慢性脑低灌注大鼠的学习记忆能力和神经元损伤的影响。方法以链脲佐菌素诱导产生实验性糖尿病大鼠,双侧颈总动脉结扎建立慢性脑低灌注模型,应用Y-迷宫评价错误次数和全天总反应时间,HE染色观察各组大鼠海马CAl区神经元的数目,免疫组化法检测海马区CDK5表达,结合蛋白质印迹(Westernblot)实验对海马区CDK5蛋白作半定量分析。结果与单纯糖尿病和慢性脑低灌注组大鼠比较,糖尿病合并慢性脑低灌注组大鼠从2w开始,迷宫作业错误反应次数增多,全天总反应时间延长,海马CAl区神经元数明显减少,CDK5蛋白表达减少。结论糖尿病加重慢性脑低灌注导致大鼠学习、记忆能力下降和神经元损伤,可能与CDK5表达减少有关。
