摘要
目的:补骨脂汤改善血管性痴呆大鼠学习记忆的作用。方法:通过双侧颈动脉结扎制作血管性痴呆模型,用RT-PCR及免疫组化方法测定海马内雌激素受体β(ER-β)、NMDAR2B(NR2B)受体基因的表达产物。结果:补骨脂汤组ER-β、NR2B基因表达的mRNA量明显高于模型组及银杏片组(P<0.05);补骨脂汤组大鼠海马CA3区的阳性细胞数均高于模型组、银杏片组(P<0.05)。结论:补骨脂汤能改善血管性痴呆大鼠的学习记忆,可能的作用途径是提高ER-β受体、NR2B受体的基因表达水平,从而提高学习记忆。
Objective:To investigate the mechanism of Buguozhi Decoction in improving learning-memory of vascular dementia model rats.Methods:The rat models with VaD were established by bilateral occlusion of both common carotid arteries(2 一V0).The gene expressions of ER-β,NR2B were evaluated by RT-PCR and immunohistochemistry.Results:Buguozhi Decoction can significantly improve mRNA and protien pruducts of ER-β,NR2B gene in hippocampus of the vascular dementia model rats,compared with the model group(P0.05).Conclusion:The mechanism of Buguozhi Decoction in improving the learningmemory of the vascular dementia model rats maybe to increase the expression of ER-βand NR2B gene.
