采用穿梭箱被动回避反应及组织化学、图像分析等法 ,研究鲜蜜蜂 10 d龄幼虫浆对 2 4月龄老年大鼠记忆保持力和大脑边缘系统海马内胆碱能神经纤维形态学影响。结果显示老龄大鼠每 d灌服鲜蜂幼虫浆 2 5 0 mg/kg,2 1d后 ,记忆力保持功能明显增强 (P<0 .0 5 ) ,胆碱能神经纤维积分光密度明显增加 (P<0 .0 5 )。初步推断蜜蜂幼虫浆具有增强老龄大鼠记忆力功能 Using shuttle box passive avoidance reaction, histochemistry, image analysis and other methods to study the effect of 10 days of fresh larvae on the memory retention of aged rats aged 24 months and the morphological changes of cholinergic nerve fibers in the hippocampus of the limbic system. The results showed that the old rats were fed with fresh bee larvae at a dose of 250 mg/kg every 2 days, and the memory retention function was significantly enhanced (P<0.05). The integral optical density of cholinergic nerve fibers was significantly increased (P<0.05). <0 .0 5 ). Preliminary inference that bee larvae pulp has enhanced memory function in aged rats
