摘要 目的:探讨普罗布考在血管性痴呆大鼠治疗中的价值,并观察大鼠海马p38MAPK蛋白表达变化。方法:将63只雄性SD大鼠分成模型组、普罗布考组以及假手术组。模型组和普罗布考组应用双侧颈总动脉永久结扎方法制作出本研究所需大鼠模型,普罗布考组大鼠给予普罗布考灌胃;假手术组与模型组则分别予以等量生理盐水灌胃,1个月后应用TUNEL法测定三组大鼠海马CA1区细胞凋亡情况,并使用Morris水迷宫实验法测定大鼠的空间认知功能,同时采取蛋白印迹法观察大鼠海马区p38MAPK蛋白表达变化情况。结果:普罗布考组大鼠在第1天、2天及3天隐蔽平台逃避潜伏时间要显著小于模型组(P<0.01);普罗布考组大鼠原平台象限停留时间明显大于模型组(P<0.01);普罗布考组大鼠海马p38MAPK蛋白表达及海马区细胞凋亡明显低于模型组(P<0.01)。结论:普罗布考用于血管性痴呆大鼠的治疗中有明显作用,可以显著提高大鼠的学习记忆能力,且能够通过对海马P38MAPK的抑制从而实现抑制海马细胞凋亡的作用。
