【Abstract】 Objective: The aim of study is to determine the melatonin levels of first episode depressive patients at acute onset and after the use of SSRI antidepressants. Methods: Using radioimmunoassay, serum levels of melatonin were determined in 18 depressive and 13 schizophrenic patients of first episode and 17 healthy volunteers. Results: Compared with schizophrenic controls of first episode, serum level of melatonin at acute onset was significantly lower in depression and improved significantly after the treatment. Conclusion: Decreased serum level of melatonin may be a part of the pathological mechanisms of depression. Radioimmunoassay is an efficiency method to determine the levels of melatonin in depression.更多还原
