摘要：

目的:观察逍遥散对慢性温和不可预知应激(CUMS)模型大鼠的行为学及脑内单胺类神经递质含量的影响。方法:应用慢性温和不可预知应激程序对大鼠进行为期11周的造模,造模后3周,分别采用逍遥散(19.5g/kg、25.0g/kg)和丙咪嗪(15.0mg/kg)对模型大鼠进行为期8周的治疗。实验进程中,定期测定大鼠体重、糖水消耗量;应用开场实验测定大鼠爬行格子数和站立次数;造模、治疗结束后处死大鼠,解剖分离大鼠皮层和海马部位,采用荧光分光光度法测定5-HLAA、5-HT、DA和NE含量。结果:与正常对照组比较。大鼠造模后3周糖水消耗量、爬行格子数和站立次数均明显减少(P<0.01);与模型对照组比较,逍遥散19.5、25.0g/kg连续给药2周能显著增加糖水消耗量,但给药4周、7周对糖水消耗量影响不明显;与模型对照组比较,逍遥散25.0g/kg连续给药7周,对大鼠体重、爬行格子数和站立次数表现出提高趋势(P>0.05),逍遥散25.0g/kg连续给药8周,能明显提高模型大鼠皮层部位5-HT含量及海马部位5-HIAA含量(P<0.05,P<0.01)。结论:逍遥散对CUMS抑郁模型大鼠表现出抗抑郁作用,作用机制与影响脑内单胺类神经递质5-HT活性有关。
