摘　　要：目的 :从神经递质与神经内分泌角度探讨抑郁症的生化病理机制。　方法 :采用高效液相色谱法及放射免疫测定法 ,分别测定 15例抑郁症患者和 2 7例正常对照者血小板 5 羟色胺 (5 HT)含量及血浆催乳素 (PRL)含量、地塞米松抑制实验 (DST)皮质醇含量。　结果 :抑郁症组血小板 5 HT水平低于正常对照组 ,血浆基础皮质醇及服地塞米松后皮质醇均高于正常对照组 ,DST阳性率高于正常对照组。　结论 :抑郁症患者存在神经递质和神经内分泌功能的紊乱 ,抑郁症的 5 HT能假说能解释其某些内分泌功能紊乱。Objective:To explore the pathophysiological mechanism of depression from the angles of neurotransmitter and neuroendocrine. Method:Platelet serotonin level was determined with high performance liquid chromatograhy (HPLC) while plasma prolactin and cortisol levels were determined with radioimmunoassay. Results:Platelet serotonin of depression was significantly lower than controls.Plasma basal cortisol level and cortisol level after taking dexamethasone were significantly lower in depressive group than in control group.The sensitivity of the dexamethasone suppression test (DST,nonsuppression of cortisol )in depressive group was significantly higher than in control group. Conclusion:There are neurotransmitter and neuroendocrine disturbances in depression.Lower serotonin in depression could explain some of the neuroendocrine disturbances.
