摘要 目的观察柴桂温胆定志汤对抑郁模型大鼠海马脑源性神经营养因子(BDNF)和特异性受体酪氨酸激酶B(TrκB)的影响。方法将42只SD大鼠随机分为6组,采用长期轻度不可预见性应激加孤养复制大鼠抑郁症模型,运用免疫组织化学法测定大鼠海马BDNF及其TrκB的表达。结果模型组大鼠海马BDNF和TrκB的表达明显低于空白对照组(P<0.01);氟西汀组、柴桂温胆定志汤高剂量组大鼠海马BDNF和TrκB的表达皆明显高于模型组(P<0.01);柴桂温胆定志汤中剂量组大鼠海马BDNF和TrκB的表达高于模型组(P<0.05)。结论柴桂温胆定志汤能提高抑郁模型大鼠海马BDNF及其受体TrκB的表达,从而保护海马神经元,可能是其抗抑郁的药理机制之一。
