目的:观察夏天无注射液(Corydalis decumbens Pers In jection,CDPI)对血管性痴呆(vascu lar dem entia,VD)大鼠学习记忆能力和海马血管生成素-1(angiopoietin-1,Ang-1)表达的影响,探讨其防治VD的作用机制。方法:采用永久性结扎双侧颈...目的:观察夏天无注射液(Corydalis decumbens Pers In jection,CDPI)对血管性痴呆(vascu lar dem entia,VD)大鼠学习记忆能力和海马血管生成素-1(angiopoietin-1,Ang-1)表达的影响,探讨其防治VD的作用机制。方法:采用永久性结扎双侧颈总动脉的方法制作VD大鼠模型,Morris水迷宫试验观察CDPI对大鼠空间辨别学习记忆能力的影响,HE染色观察海马的组织病理学变化,免疫组化染色,图像分析半定量测定Ang-1的表达。结果:CDPI 2 mg/kg、5 mg/kg治疗VD大鼠1个月和2个月后,显著缩短逃避潜伏期和搜索距离;治疗2个月后,明显增加海马内Ang-1的表达。结论:CDPI可明显改善VD大鼠的学习记忆能力,其作用机制可能与增加海马内Ang-1的表达有关。展开更多
