title: Possible increase of dopamine-beta-hydroxylase activity in the locus ceruleus of paranoid schizophrenic patients: a preliminary post-mortem study.
abstract: Five schizophrenic brains and seven control brains were compared for phenylethanolamine-N-methyl-transferase and dopamine-beta-hydroxylase activities. The two groups were comparable in age, sex, and post-mortem delay before autopsy. A radioenzymatic assay showed a statistically significant increase of dopamine-beta-hydroxylase activity in the rostral part of the locus ceruleus in the schizophrenic brains.
