Serotonin released in synapsis is one of the key neurotransmitters in psychiatry and psychopharmacology. The loudness dependence of auditory evoked potentials (LDAEP) has been proposed as a marker for central serotonergic neurotransmission. Several findings in animals and humans support this hypothesis. However, the in vivo measurement of cortical(More)
Several genes of the dopaminergic and glutamatergic neurotransmitter systems have been found to be associated with alcohol disease and related intermediate phenotypes. Here, we evaluated genetic variants of the catechol-O-methyltransferase (COMT) and the metabotropic glutamate receptor 3 (mGluR3) genes in alcohol-dependent patients and their association(More)
BACKGROUND Antipsychotic-induced weight gain (AIWG) is a serious side-effect of antipsychotic medication leading to metabolic syndrome and increased cardiovascular morbidity. Unfortunately, there are still no valid predictors to assess an individual's risk to gain weight. Previous studies have indicated an impact of genetic variation in the genes encoding(More)
The nicotinic system is involved in the pathophysiology of schizophrenia. However, very little is known about its genetic basis and how it relates to clinical symptoms and potentially pharmacological intervention. Here, we investigated five single nucleotide polymorphisms (SNPs) [rs3826029] [rs2337506] [rs982574] [rs904952] [rs2337980] of the cholinergic(More)
In 95 schizophrenic patients, 20 endogenous depressed patients and 39 control subjects the level of plasma tryptophan was determined after oral load of L-tryptophan (50 mg/kg) in range of 3 hours. Among the groups quantitative and specially qualitative differences were observed in course of tryptophan. In the group of schizophrenic patients it is possible(More)
The effect of pargyline on 5 HT concentration in a combined forebrain and midbrain section ( FMB ) have been investigated in female rats which were temporarily deprived from their dams in postnatal life and daily injected with the monoamine oxidase inhibitor. Two hours after the last pargyline injection a marked increase in 5 HT concentration could be(More)
