The whole blood serotonin (5-hydroxytryptamine (5-HT)) & monoamine oxidase (MAO) activity in 9 female chronically suicidal outpatients was measured. Subjects were referred for a biweekly group training course aimed at modifying depressive & suicidal cognitions & behaviour. Data confirm that platelet MAO activity behaved as a trait marker & 5-HT behaved as a state marker in these moderately depressed subjects. (6 refs.)
