To explore the possible role of serotonin (5-HT) in the etiology of schizophrenia, platelet 5-HT concentrations were determined in 41 schizophrenic (and schizoaffective, mainly schizophrenic) patients diagnosed by the RDC and 34 normal controls. There was a significant difference between the patient and control groups with the 16 paranoid, 11(More)
The authors determined the platelet MAO activity of 57 psychotic patients after a placebo period and after 3-65 days of neuroleptic treatment. Platelet MAO activity significantly decreased in both men and women after neuroleptic treatment. The platelet MAO activity of neuroleptic-treated schizophrenic women was significantly less than that of drug-free(More)
Platelet monoamine oxidase (MAO) activity was studied in 33 in-patients with bipolar and schizoaffective disorder who were treated with lithium. Platelet MAO activity was found to increase following 10-41 dys of lithium treatment compared to a prior drug free period, and the increase was positively correlated with the duration of lithium treatment. The(More)
Hypo- and hyperthermic responses resulting from the activation of putative 5-HT1A and 5-HT2 receptors, respectively, were examined after the chronic treatment of rats with monoamine oxidase inhibitors. The treatment of rats for 4 or 7 days with nialamide (40 mg/kg, twice daily) resulted in a suppression of the hypothermic effect of the 5-HT1A agonist(More)
Computed Tomography (CT) was used to assess lateral ventricular size in 20 psychiatric inpatients who had participated in at least 5 weeks of a fixed dose chlorpromazine (CPZ) trial. During treatment with CPZ, eight patients had required antiparkinsonian medication for treatment of rigidity. The ventricular brain ratio (VBR) of these eight patients was(More)
Monoamine oxidase (MAO) activity has been studied in postmortem brain specimens from chronic schizophrenics and comparison groups by various laboratories. There is no evidence for decreased MAO activity in the brains of the schizophrenic patients, but many possible sources of error in postmortem studies make the conclusions of these studies less than(More)
Methysergide maleate, a 5-hydroxytryptamine receptor blocker, was administered to cats deprived of paradoxical sleep for 48 hours. During the first six hours after methysergide, the latency to the first slow-wave sleep and paradoxical sleep episodes was increased and total sleep time decreased. The decrease in sleep reflects a loss of paradoxical sleep,(More)
