title: Plasma total and free tryptophan concentration in 'neurotic' and 'psychotic' depressive patients.
abstract: Plasma levels of total and free tryptophan were measured in patients with depressive neurosis and depressive psychosis, before and after recovery. No significant differences were found in total or free plasma tryptophan levels between 'neurotic' and 'psychotic' groups, and no change in these levels was found on recovery from depressive illness.
