摘要 目的:探讨益智宁对注意缺陷多动障碍(ADHD)动物模型-自发性高血压大鼠(SHR)前额叶皮质及纹状体中酪氨酸羟化酶(TH)、多巴胺转运体(DAT)、多巴胺D1受体(DRD1)、多巴胺D2受体(DRD2)蛋白和基因表达的影响。方法:36只SHR雄性大鼠随机分为3组,分别用益智宁煎剂、盐酸哌甲酯和生理盐水灌胃28d,采用免疫组化法和原位杂交法检测其前额叶皮质、纹状体中TH、DAT、DAR1、DRD2蛋白和基因的表达。结果:在SHR大鼠的前额叶皮质及纹状体,TH蛋白和基因的表达,益智宁组高于盐酸哌甲酯组,盐酸哌甲酯组又高于生理盐水对照组;DAT蛋白和基因表达,益智宁组低于盐酸哌甲酯组,盐酸哌甲酯组又低于生理盐水对照组;DRD1和DRD2的蛋白和基因表达,益智宁组和盐酸哌甲酯组均低于生理盐水对照组;差异均有统计学意义(P<0.05)。结论:益智宁可能通过影响调控中枢前额叶皮质-基底神经节环路的DA神经信号传导而治疗ADHD。
