摘要:目的 研究疏肝活血方对血管性痴呆(VD)大鼠学习记忆的影响。方法 采用改进的2VO法制备VD大鼠模型。雄性SD大鼠90只,随机分为模型组、假手术组、多奈哌齐组、疏肝活血方高、中、低剂量组,每组15只。于造模3 d后开始灌胃给药,每天1次,连续4周。给药后4周行水迷宫实验进行行为学测试。结果 疏肝活血方中剂量组大鼠学习记忆成绩明显高于模型组大鼠,差异有统计学意义(P<005)。结论 疏肝活血方能提高血管性痴呆大鼠的学习记忆能力。

【Abstract】Objective: To study the effect of Shugan Huoxue Prescription on learning and memory in vascular dementia (VD) rats Methods: VD rat model was prepared by modified 2VO method 90 male SD rats were randomly divided into a model group, a sham operation group, a donepezil group and Shugan Huoxue Decoction groups of high, medium and low dose, 15 rats each group Three days after modeling, the rats were given oral administration, once a day for 4 weeks Four weeks after administration, water maze test was conducted for behavioral testing Results: The learning and memory scores of Shugan Huoxue Decoction groups were significantly higher than those of the model group and the difference was statistically significant (P<005) Conclusion: Shugan Huoxue Prescription can improve the learning and memory ability of vascular dementia rats

血管性癡呆((vascular dementia,VD)是因脑血管疾病所致的智能及认知功能障碍的临床综合征。其发病率在所有痴呆类型中居第二位,仅次于阿尔茨海默(Alzheimer disease,AD)。在我国及日本等亚洲国家,由于脑血管病(主要是缺血性脑血管病)的高发,VD发病率较欧美其他国家为高。据流行病学调查,在欧美,VD仅占老年性痴呆的30%,而在我国其比例高达60%[1]。我国的一项流行病学调查显示,我国65岁及以上人群中VD的患病率为13%[2],随着世界人口老龄化的发展及卒中治疗死亡率的降低,VD发病率有逐年上升趋势。患者的学习,记忆能力受损,伴随情感、性格的改变,严重影响其日常生活,给家庭和社会带来巨大的经济和精神负担。世界卫生组织(WHO)已将VD列为21世纪的重点研究项目。有资料报道,VD比阿尔茨海默病(AD)更有预防和治疗价值[3]。因此对血管性痴呆的脑损伤机制及其防治的研究,是我国以及世界医学领域联合公关、重点研究的项目。……
