The authors found lower platelet monoamine oxidase (MAO) activity in 13
unmedicated chronic schizophrenic male patients in comparison to 13
mentally normal control male subjects--a finding that agrees with previous
studies showing MAO activity to be low in the platelets of chronic
schizophrenic patients. The authors urge that studies exploring endocrine
factors and the role of hospitalization be undertaken to attempt to explain
this finding.Abstract Teaser
