摘要:

以东莨菪碱和乙醇分别造成小鼠学习记忆获得障碍和记忆再现障碍,采用迷津法和跳台法观察并比较怀山药和吡拉西坦对小鼠学习记忆能力的影响。结果显示:怀山药(20g/kg 和30g/kg)及吡拉西坦(0.2g/kg)均可使小鼠逃避伤害刺激的反应速度加快,错误次数明显减少,遭电击时间缩短(与模型组比较,0.01 < P < 0.05),两药的效果相近(P > 0.05)。因此,怀山药对小鼠的学习和记忆障碍有改善作用,其作用机制有待进一步研究。

Abstract:

Acquired dysmnesia and memory disorder models caused by scopolamine and alcohol, respectively, were used to compare the effects of Dioscorea opposita and piracetam on learning and memory function in mice by maze and step-down methods. Results indicated that aqueous extract of Dioscorea opposita could obviously improve learning and memory ability in mice. Compared with model group, groups treated with the extract at doses of 20 g /kg and 30 g/kg or piracetam exhibited fewer error times, longer latent period and shorter total time of electronic shock (0.01 < P < 0.05). While no significant difference between Dioscorea opposite-treated and piracetam-treated groups was observed (P > 0.05). Therefore, Dioscorea opposita can obviously improve the ability of learning and memory in mice. However, further investigations on the related mechanisms are needed.

Key words: Dioscorea opposita, piracetam, acquired dysmnesia, memory disorder
