[The preliminary study of monoamine oxidase activity in platelets in patients with schizophrenia and affective disorder].

Abstract

This paper has studied the MAO activity in platelets of 52 schizophrenic patients and 44 affective disorder patients. The results indicate that the MAO activity in platelets of schizophrenic patients is lower than that of normal group, especially the chronic schizophrenic patients. It's no difference between the acute schizophrenic patients and normal group. The MAO activity in platelets of bipolar affective disorder patients is much lower than that of normal group. Platelet MAO activity in male bipolar affective disorder is lower than that of female's, that of bipolar-manic effective disorder is lower than that of bipolar-depressive effective disorder. The MAO activity in platelets of unipolar depression is even lower than that of normal group.
