Activities of blood glutathione peroxidase in schizophrenic and depressive patients.

Abstract

Glutathione peroxidase activity was determined in the blood of healthy individuals and schizophrenic and depressive patients. No significant changes in enzyme activity were observed between the groups of patients. A slight decrease in glutathione peroxidase activity was found in the group of schizophrenic men and in the groups of depressive patients. The treatment with neuroleptics did not influence enzyme activity with an exception--the group of depressive men.
