摘要 目的通过观察抑郁模型大鼠快速动眼相睡眠剥夺(REMSD)后的行为学及海马氨基酸类神经递质含量的变化,探讨睡眠剥夺的抗抑郁机制。方法30只成年雌雄各半的SD大鼠,随机分为正常组、抑郁模型组和睡眠剥夺组,每组10只。后两组采用孤养和长期不可预见的中等强度应激造大鼠抑郁模型,睡眠剥夺组又采用小平台水环境法进行72hREMSD,以开场试验检测大鼠自主活动,用高效液相色谱-荧光检测法测定大鼠海马氨基酸类神经递质含量。结果与正常组相比,模型组大鼠自主活动显著减少,海马谷氨酸(Glu)含量显著升高(P<0.01),γ-氨基丁酸(GABA)含量显著降低(P<0.01)。而睡眠剥夺组大鼠所测各项指标与正常组相比无显著差异(P>0.05)。结论REMSD可逆转抑郁模型大鼠的抑郁样行为,其抗抑郁作用与其对海马内氨基酸类递质的调整相关。
