祁州漏芦乙醇提取物改善记忆障碍的实验研究

Research on amnesia improving effect of alcohol extract of Rhoponticum uniflorum

目的 :研究漏芦乙醇提取物对小鼠学习记忆功能的影响及其对脑和全血胆碱酯酶活性的影响。方法 :采用一次性被动回避式条件反射的方法 (跳台法 )考察药物对小鼠学习记忆功能的影响。结果 :漏芦乙醇提取物能显著对抗东莨菪碱所致的记忆获得障碍及环己酰亚胺所致的记忆巩固障碍 ;显著抑制脑和全血胆碱酯酶活性。结论

Objective: To study the effects of the alcohol extract of Loulu (AEL) on the ability of learning and memory in mice and on the activity of cholinesterase in brain and whole blood.Methods: In order to establish the effect of the alcohol ectract of Loulu on the ability of learning and membory in mice, the methods of one trial passive avoidance response(step down test) were used. Results: The AEL could antagonize the acquisition impairment of memory induced by scopolamine (SCPL) and the consolidation disruption of memory elicited by cycloheximide (CYC), inhibit the activity of cholinesterase in brain and whole blood. Conclusion: The improving effect of the AEL on the ability of learning and memory might be related with its effect of improving function of the central cholinesterase system.
