    Notizen: Abstract Basal morning humoral (H)-endorphin blood levels were assessed in ten autistic patients, 12 chronic schizophrenic patients and 11 healthy control subjects. Four autistic patients and four schizophrenic patients were drug free for at least 6 months while all other psychiatric patients were under treatment with antidopaminergic agents. Significantly reduced opioid levels were observed in the autistic group (827±103 vs 1121±75 pg-eq/ml, P〈0.025), although the difference was actually only 26% of the control mean. A similar tendency toward low H-endorphin levels was also observed in the schizophrenic patients; however this difference was not significant (919±129 vs 1121±75 pg-eq/ml; NS). No significant difference was obtained between subjects suffering from the two psychiatric disorders (827±103 vs 919±129 pg-eq/ml; NS). Various interpretations of the decreased secretion of H-endorphin are discussed.

    Notizen: Abstract The possible involvement of serotonin receptors of the 5HT2 type in aggressive behavior was studied in juvenile delinquents. A group of 28 delinquent adolescents (13–18 years old) who had committed violent crimes was compared with a group of age matched controls. Subjects were drug and medication free during the study. 5HT2 receptors were labeled on platelet membranes using tritiated ketanserin. Receptor binding in the delinquent adolescents was significantly lower than in age matched controls. Mean ± SD of 76 controls was 32.3±14.2 fm/mg, compared to 16.6±8.2 fm/mg in 28 delinquents (P〈0.002, Student'st-test). These results support a role for serotonin in general and 5HT2 receptors in particular in human aggressive behavior.

    Notizen: Abstract [3H]Imipramine binding to platelet membranes was evaluated in ten autistics, eight schizophrenics and seven normal controls. The schizophrenics and eight out of the ten autistics were maintained on chronic neuroleptic treatment. Diagnosis of autism and schizophrenia was established according to the DSM-III criteria. No significant difference in the maximal binding capacity of [3H]imipramine (B max) andK d values could be found among the three groups. It seems that the imipramine binding site is intact both in autism and schizophrenia.
