摘  要:目的探讨限制性制动方法建立大鼠心理应激性失眠模型的可行性。方法采取限制性制动方法、行为学测量、多导睡眠描记、放射免疫法测量和高效液相色谱分析。结果与对照组比较,限制型制动模型大鼠造模后觉醒时间增加、非快眼动(NREM)睡眠时间和8波减少;造模后第15天模型大鼠NREM睡眠8波比例减少[模型组:(49.08±11.33)%;对照组:(53.30±8.76)%],睡眠觉醒次数转换增加[模型组:(41.00±16.84)次;对照组:(33.63±8.42)次];体质量下降14.07%(P〈0.05)、旷场实验中水平活动减少60.49%(P〈0.01),垂直活动减少71.91%(P〈0.01),鼠尾悬挂实验中悬尾后的不动时间增加49.46%(P〈0.01),血清ACTH、CORT、B-EP、E和NE分别增加87.02%(P〈0.01)、46.05%(P〈0.05)、39.89%(P〈0.01)、470.54%(P〈0.01)和17.78%(P〉0.05)。结论限制性制动是建立大鼠心理应激性失眠模型可行性的方法。Objective To investigate the feasibility of developing psychological stress insomnia model of rats by restricting activity. Methods Restriction of activity, behavioral test, polysomnogram recording, radioim-munity, and high performance liquid chromatogram analysis were used in this study. Results Compared with control, the ratio of non-rapid eye movement (NREM) sleep and its delta wave decreased after restriction ; On day 15, the ratio of delta wave in NREM sleep decreased (49.08±11.33 in model group vs 53.30±8.76 in con-trol) ; the number of wake increased (41.00±16.84 in model group vs 33.63±8.42 in control); the body weight of model group decreased by 14.07 percent ( P〈 0.05 ) ; ambulation reduced by 60.49 percent ( P〈 0.01 ) and the rearing reduced by 71.91 percent( P 〈 0.01 )in open-field test. In rat suspend tail test, the immobility time increased by 49.46 percent ( P〈 0.01 ). Moreover, the serum ACTH, CORT, [β-EP, E and NE increased by 87.02 percent ( P 〈 0.01 ) ,46.05 percent ( P 〈 0.05 ) ,39.89 percent ( P 〈 0.01 ) ,470.54 percent ( P 〈 0.01 ) and 17.78 percent ( P 〉 0.05 ) respectively on day 15. Conclusion Restriction of activity is a feasible way of developing psychological stress insomnia model of rats.
