Platelet monoamine oxidase in chronic schizophrenic patients
PA Berger, RA Ginsburg, JD Barchas, DL Murphy and RJ Wyatt
The authors investigated platelet monoamine (MAO) activity in 40 chronic
schizophrenic patients, 55 normal control subjects, and 16 hospitalized
control subjects. The mean platelet MAO activity for the chronic
schizophrenic patients was significantly lower than the mean in either
control group. There were no significant differences between the mean
platelet MAO activities in 21 chronic paranoid schizophrenic patients
compared with 18 chronic undifferentiated schizophrenic patients.
