SCHIZO {PASWR2}

Dopamine Activity

Description

Twenty-five patients with schizophrenia were classified as psychotic or nonpsychotic after being treated with an antipsychotic drug. Samples of cerebral fluid were taken from each patient and assayed for dopamine \beta-hydroxylase (DBH) activity. The dopamine measurements for the two groups are in nmol/ml-hour per milligram of protein.
