摘要
目的检测一种新颖的褪黑素受体激动剂Neu-P11与褪黑素对大鼠物体识别记忆的影响。方法大鼠物体识别测试包括两个阶段即4 min的训练期和3 min的测试期。在上午或下午于训练前2 h注射Neu-P11(50 mg/kg)、褪黑素(50 mg/kg)或溶媒。训练结束后4 h或24 h,分别检测大鼠的短时程与长时程记忆保持。记录并分析各组大鼠在训练期的总探究时间与测试期的辨别指数。结果在短时程记忆及长时程记忆测试中,无论上午或下午给药,各组大鼠在训练期间的总探究时间组间差异无显著性,且Neu-P11处理组大鼠其辨别指数均显著性高于溶媒组;褪黑素处理组大鼠仅在下午给药时其辨别指数显著性高于溶媒组。结论 Neu-P11与褪黑素均能增强大鼠物体识别记忆,且Neu-P11的效应是给药时间非依赖的。
