The activities of dopamine beta hydroxylase (DBH) in plasma and methionine activating enzyme (MAE) in red blood cells were determined in chronic schizophrenic patients on phenothiazine medication and a control population. The mean activities of DBH and MAE were not statistically different in the schizophrenic patients; subdivision of these patients into catatonic, paranoid and undifferentiated types also failed to produce differences in the activities of these enzymes. These findings are discussed in relation to current hypotheses regarding biologic factors in the etiology of schizophrenia.
