Several studies have reported decreased platelet 5-HT uptake in patients of major depression. The present study was undertaken with the aim to study the active platelet 5-HT uptake in depressed patients and effect of treatment with imipramine/ECT on platelet 5-HT uptake in these patients. 30 patients of major depression and equal number of age and sex-matched controls were included in the study. The depressives received imipramine (N=15) or ECT (N=15). Pretreatment active platelet 5-HT uptake was lower in depressives. Treatment with imipramine resulted in significant decrease in 5-HT uptake while with ECT there was significant increase. The serotonergic mechanisms are discussed.
几项研究报告指出,重度抑郁症患者的血小板 5-羟色胺摄取减少。本研究旨在研究抑郁症患者的活跃血小板 5-羟色胺摄取情况,以及用丙咪嗪/ECT 治疗对这些患者血小板 5-羟色胺摄取的影响。研究纳入了 30 名重度抑郁症患者和与之年龄、性别匹配的对照组。抑郁症患者接受丙咪嗪(N=15)或电抽搐治疗(N=15)。治疗前,抑郁症患者的血小板 5-羟色胺摄取活性较低。丙咪嗪治疗可显著降低 5-羟色胺摄取,而电抽搐治疗则显著增加。本文讨论了 5-羟色胺能机制。
