The aim of this study was to investigate the relationship between plasma glutamate, glutamine and γ-aminobutyric acid (GABA) levels in female patients with major depression treated with S-citalopram or fluoxetine. The patients were assigned into S-citalopram (10 mg/day) or fluoxetine (20 mg/day) groups (n = 15 per group). The Hamilton and Beck Depression(More)
Fluoxetine, as a serotonin re-uptake inhibitor augments serotonin concentration within the synapse by inhibiting the serotonin transporter. The contribution of amino acids has also been shown in depression. We hypothesized that fluoxetine exerts its actions at least in part by intervening brain signaling operated by amino acid transmitters. Therefore the(More)
Cholestasis contributes to the genesis of fatigue through several mechanisms. Among these mechanisms, affected serotonergic neurotransmission is important in the pathogenesis of central fatigue. Previously, elevated levels of 5-hydroxyindole acetic acid (5-HIAA), the metabolite of 5-hydroxytryptamine (5-HT) and increased 5-HT(2) receptor density were(More)
Genetic absence epilepsy rats from Strasbourg (GAERS), a selectively inbred strain of Wistar rats, has been validated as an experimental model for human absence epilepsy. In this model, systemic administration of ethosuximide (ETX) was shown to reduce the spike and wave discharges (SWD). In this study, gamma-aminobutyric acid (GABA) and L-glutamic acid(More)
BACKGROUND/AIM Drug-drug interactions (DDIs) can impact patient safety. Occurrence of clinically important DDIs is higher for intensive care unit (ICU) patients. This observational study aimed to evaluate the potential DDIs in medical ICU patients of a university hospital. MATERIALS AND METHODS The Medical Pharmacology Department organized consultation(More)
1 In the present study we have investigated the expression of muscarinic receptors in K562 erythroleukaemic cells and the effects of muscarinic agonist and antagonists on extracellular citrulline levels in these cells, as a marker of nitric oxide (NO) generation. 2 Muscarinic acetylcholine receptors (M(1)-M(5)) play key roles in regulating many diverse(More)
