We have characterized the alpha-bungarotoxin receptors (BgtRs) found on the cell surface of undifferentiated pheochromocytoma (PC12) cells. The PC12 cells express a homogeneous population of alpha7-containing receptors that bind alpha-Bgt with high affinity (Kd = 94 pM). The BgtRs mediate most of the response elicited by nicotine, because the BgtR-specific antagonists methyllycaconitine and alp...
objective: the present study aimed to review the relapse rate in patients with schizophrenia treated with orally taken atypical agents (serotonin dopamine antagonists, sdas) and depot preparation of conventional (typical) antipsychotics. methods: in this historical cohort study, mean relapse per month (mrm) index, duration between initiation of antipsychotic treatment and the first relapse epis...
in the present study the effects of both cck receptor agonists and antagonists on antinociception induced by morphine in the tail-flick test have been evaluated. m orphine induced dose-dependent antinociception in mice. the response of morphine was potentiated by sulfated cholecystokinin-8 (cck-8s) but not by unsulfated cholecystokinin-8 (cck-8u). the cck receptor antagonists mk-329 and l-365, ...
PURPOSE Numerous antiemetics have been studied for the prevention of postoperative nausea and vomiting (PONV) including traditional agents (metoclopramide, perphenazine, prochlorperazine, cyclizine and droperidol) and the 5-HT3 receptor antagonists (ondansetron, dolasetron, granisetron and tropisetron). The results have been divergent and inconsistent. The purpose of this quantitative systemati...
The pathophysiology of obsessive-compulsive disorder (OCD) remains unknown. However, increasing attention has been paid to the putative role of the serotoninergic system, the strongest evidence being based on the widely demonstrated efficacy of serotonin (5HT) reuptake inhibitor antidepressants in the treatment of OCD. The therapeutic effects are correlated with changes in peripheral parameters...
Background: IGF-1 and certain other cytokines have been shown to exert inflammatory/anti-inflammatory roles in chronic joint diseases. Objective: To assess the effect of IGF-1, IL-27 and IL-35, their interaction and their receptor expression in a rheumatoid arthritis model. Methods: Freund’s adjuvant-induced chronic joint inflammation was operated on 160 male rats. Animals were divided into his...
conclusions the application of 5-ht1a, 5-ht2, 5-ht3, 5-ht4, 5-ht6 and 5-ht7 receptor antagonists, applied at concentrations lower than 1.0 µm did not modify the efs-induced contraction and relaxation responses, whichsuggests the unlikely involvement of endogenous 5-ht in mediating responses to efs in the described test conditions. materials and methods segments taken from the rat duodenum, jeju...
Serotonin (5HT) is a constituent of the so-called "inflammatory soup" that sensitizes nociceptors during inflammation. Nevertheless, receptors and signaling mechanisms that mediate an excitation of dorsal root ganglion (DRG) neurons by 5HT remained controversial. Therefore, capsaicin-sensitive nociceptive neurons dissociated from rat DRGs were used to investigate effects of 5HT on membrane exci...
