Carbamazepine, a drug effective in pain, seizure, and affective disorders, was screened for its ability to interact with a variety of neurotransmitter and neuromodulator binding sites on brain membranes. The most potent effect was observed on adenosine antagonist ( [3H]DPX) binding to the adenosine receptor (KI = 3.5 +/- 0.4 microM) followed by adenosine(More)
Gonadal hormones are believed to be involved in the pathophysiology of premenstrual changes (PMC) possibly through their interaction with neurotransmitter systems in the brain. The serotonergic system, an important central modulator of mood and behavior which is involved in the pathophysiology of affective disorders has been suggested to play a role in the(More)
In 17 chronic schizophrenic patients under chronic neuroleptic treatment for 13 years, a 30-day drug withdrawal resulted in early relapse of four patients, slight deterioration in five, and slight amelioration in eight patients. No incidence of neuroleptic symptoms such as tardive dyskinesia occurred. Prolactin in plasma and cerebrospinal fluid (CSF), not(More)
The estimation of serum prolactin (Prl) and norepinephrine (NE) in chronic schizophrenics treated with neuroleptics for 5-25 years showed no elevated Prl levels in either men or women (4.9 +/- 4.1 and 13.7 +/- 12.1 ng/ml, respectively). No significant correlation to duration or dosage of neuroleptic treatment, psychopathological syndromes and occurrence of(More)
Imipramine (IMI) binding and serotonin (5-HT) uptake were determined in platelets of 98 healthy volunteers; and their association with age, sex and circadian rhythm were evaluated. A large interindividual variability was found for both IMI and 5-HT parameters. There was a negative correlation of IMI affinity constant (Kd) and binding (Bmax) with age, but no(More)
The effects of two different kinds of stress (social and physical) on central adenosine receptors were investigated in mouse whole brain membranes using 1,3-diethyl-8-[3H]phenylxanthine ([3H]DPX) as a ligand. Chronic but not acute social stress induced an increase in the number of adenosine receptors similar to that induced by chronic, nontoxic doses of(More)
The influence of short-time emotional and cognitive stimuli on autonomic functions and plasma catecholamines was investigated in 12 paranoid schizophrenics, 12 endogenous depressive patients, and 63 normal controls. The schizophrenics showed higher norepinephrine levels, depressives higher epinephrine levels; in both groups of patients most of the(More)
Afternoon continuous plasma levels of 3-methoxy-4-hydroxyphenylglycol (MHPG) were first shown to be a good representation of the mean 24-hour plasma level of MHPG in 18 normal subjects. Then, after the stability of the procedure was tested and retested, the afternoon continuous test for plasma MHPG levels was performed in 57 normal subjects and 42(More)
The sensitivity of the dopaminergic hypothalamic pituitary system, as indicated by growth hormone (GH) release after apomorphine (0.5 mg SC), was studied in 11 chronic schizophrenic in-patients under long-term neuroleptic (NL) therapy and after 12 and 30 days' drug withdrawal. GH peak levels after a 12-day drug-free period were significantly elevated (13.1(More)
