Abstract

目的 通过测定血小板五羟色胺(5-HT)水平,探讨难治性抑郁症患者的相关生化机制特点.方法 采用一般情况问卷(自编)、汉密顿抑郁量表17项(HAMD17)、汉密顿焦虑量表(HAMA)评定难治性抑郁症患者的一般情况与焦虑抑郁情绪,测定患者外周血小板5-HT含量.结果 共收集难治性抑郁症患者38例,血小板5-HT值为(99.9±118.5)ng/109,60例非难治性抑郁症患者为(242.8±174.4)ng/109,2组差异有显著性(P<0.01);难治性抑郁症患者血小板5-HT含量和本次病程长短、HAMD行为阻滞因子存在正相关关系.结论 难治性抑郁症患者的血小板5-HT含量水平较低,与本次发作病程长短和行为阻滞症状之间存在一定的关系。
