柴郁温胆汤对大鼠抑郁模型行为学及脑内单胺类神经递质的影响

目的:探讨中药复方柴郁温胆汤抗抑郁作用的机制.方法:以孤养加慢性轻度不可预见性应激方法建立大鼠抑郁症模型,用旷场行为测定及糖水消耗试验进行行为学评分,并用高效液相 - 电化学方法检测其脑内单胺类神经递质的含量,观察模型大鼠给药前后的变化.结果:抑郁症模型大鼠体质量增长缓慢,水平和垂直活动及糖水消耗量均明显减少(P<0.05,P<0.01);杏仁核NE、DA、5-HT、HVA含量减少(P<0.05);纹状体NE、DA、5-HT含量减少(P<0.05).柴郁温胆汤能改善模型大鼠行为学变化,升高杏仁核NE、5-HIAA、5-HT、HVA(P<0.05)及DA含量(P<0.01),升高纹状体DA和5-HT含量(P<0.05).结论:柴郁温胆汤具有抗抑郁作用,对中枢单胺类神经递质的调节作用是其疗效机制之一.

Effects of Chaiyuwendan Decoction on ethology and monoamine neurotransmitters in brain of depressive disorder rats

Objective:To study the anti-depression mechanism of Chaiyuwendan Decoction(CYWDD).Methods:Rat models were established by separation and chronic unpredictable mild stress(CUMS).Ethology of rats were detected by open-field test and sucrose consumption test,contents of monoamine neurotransmitters were detected by HPLC-ECD.Results:Compared with normal group,the weight,the frequency of crossing,rearing and the contents of consumption to sucrosum water in depressive disorder rats decreased significantly(P<0.05,P<...
