title: Neurotransmitter parameters in plasma and urine of affective patients in depression and in normothymia after drug treatment.
abstract: Several neurochemical parameters were estimated in plasma and urine of patients with affective disorders in the depressive phase and later in normothymia, after successful drug treatment. Significant increases were found for the activity of the enzyme dopamine-beta-hydroxylase in plasma and the concentrations of cyclic AMP in plasma and urine. No consistent changes were found for prolactin or cyclic GMP in plasma, and for methoxyhydroxyphenylgkyglycol, homovanillic acid, 5-hydroxyindoleacetic acid and cyclic GMP in urine. The major change we observed in the clinical state of the patients is thus not reflected in change in the urinary biogenic amine metabolites. Their changes were found to correlate inversely to their pretreatment values. In normothymia, high values decrease and low values increase for all three amine metabolites, indicating that antidepressives act towards a normalization of the amine turnover mechanisms.
