肝郁脾虚证大鼠双侧杏仁核注射CNQX后行为变化及逍遥散的调节作用

目的:从行为学角度探讨逍遥散治疗肝郁脾虚证的调节机制。方法:75只雄性SD大鼠随机等分为5组,正常组、模型组、假手术组、6-氰基-7-硝基喹喔啉-2,3-二酮(CNQX)组和逍遥散组。以21d慢性束缚应激方法造肝郁脾虚证模型组,在此基础上,运用脑立体定位仪埋管微量注射α-氨基羟甲基恶唑丙酸(AMPA)受体的拮抗剂造CNQX组,为评估手术创伤对模型的影响程度加造假手术组。逍遥散组造模方法和CNQX组相似,突出逍遥散和CNQX二者干预的可比性,于第1、7、14、21天分别比较CNQX组和逍遥散组行为变化各项指标趋势是否一致。结果:模型组大鼠逐步呈现肝郁脾虚证表现;CNQX组起到干预治疗作用,大鼠焦躁状态得到抑制;逍遥散组大鼠表现自然,逍遥散起到较好的调节作用。排除了手术创伤等混杂因子,逍遥散组和CNQX组行为学实验结果变化趋势逐步相似。结论:结合前期RT-PCR和免疫组化实验,从宏观行为学角度,进一步推断逍遥散和CNQX有一条相似作用通路,即通过纠正杏仁核和海马的"兴奋-抑制"失衡,重建稳态,来治疗肝郁脾虚证。

Behavior study and Xiaoyao Powder,s regulation on the 'syndrome of liver invading the spleen' rats injected CNQX in Bilateral amygdala

Objective: This behavior experiment was designed to explore the regulation channel of Xiaoyao Powder treating rats of 'syndrome of liver invading the spleen'.Methods: 75 male SD rats were randomly divided into 5 equal groups: normal group,CIS group,sham-operation group,CNQX group and Xiaoyao Powder group.The number of GluR2 positive cells in hippocampal subregion CA1 and amygdaloid subregion BLA in these 5 groups.Rats of B,C,D,E groups were restrained 3 hours per day for 21days to establish model of 'syndro...
