Summary

Opioid receptor binding sites were assessed in membrane preparations of caudate nucleus from post-mortem brains of controls and of patients with schizophrenia. There was no difference between the two groups in the total specific binding of 3H-etorphine or in its ‘μ’ and (‘δ+χ’) components. Similarly, the binding of 3H-naloxone did not differ between patients and controls. It is concluded that a previous report of reduced opioid receptors in caudate of schizophrenics is unlikely to prove a consistent finding and that the results of the present study offer no support to the claim that there is a general disturbance in opiate mechanisms in schizophrenia.
