Platelet 5-HT and plasma cortisol concentrations after dexamethasone suppression test in patients with different time course of schizophrenia.

abstract：:Based on 5-HT hypothesis, L-5-HTP (150 or 300 mg/day) was given orally to 18 depressed patients. The global estimates were 2 very much improved; 8 much improved; 3 minimally improved, and 5 unchanged. The action of L-5-HTP was usually rapid. The elevation of the serum 5-HT level 1 week after L-5-HTP administration was...
