[Correlation of the results of neurotensin therapy and plasma levels in paranoid schizophrenia].
The subjects were 21 paranoid schizophrenic patients (10 women, 11 men). The average duration of illness was 4.5 years. The severity of psychopathological symptoms was evaluated using BPRS-LA before and on 7 and 21 day of trifluoperazine therapy (60 mg per os).
