in the present study, the effect of gaba (γ-aminobutyric acid) receptor agonists and antagonists on morphine-induced antinociception was investigated in formalin test in rats. intraperitoneal (i.p.) injection of different doses of morphine (1, 3, 6 and 9 mg/kg) and intracerebroventricular (i.c.v.) injection of different doses of muscimol (0.5, 1 and 2 g/rat) or baclofen (0.25, 0.5 and 1 g/rat) ...

In this study, the influence of dopamine receptor agonists and antagonists on antinociception induced by bac10fen has been examined in the formalin test. The GABA-B agonist bac10fen induced antinociception in both phases of the formalin test in mice. The dopamine receptor agonists SKF 38393 and quinpirole also induced antinociception in both phases of the test. SKF 38393 but not quinpirole ...

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-...

PURPOSE To learn whether gamma-aminobutyric acid (GABA) participates in retinal mechanisms that influence refractive development. METHODS White leghorn chicks, some of which wore a unilateral goggle to induce myopia, received daily intravitreal injections of agonists or antagonists to the major GABA receptor subtypes. Eyes were studied with refractometry, ultrasound, and calipers. Retinas of ...
GABA(C) receptors are the least studied of the three major classes of GABA receptors. The physiological roles of GABA(C) receptors are still being unravelled and the pharmacology of these receptors is being developed. A range of agents has been described that act on GABA(C) receptors with varying degrees of specificity as agonists, partial agonists, antagonists and allosteric modulators. Pharma...
The pharmacology of nicotinic receptor-mediated seizures was investigated in C3H mice. Eleven nicotinic agonists and six antagonists were administered centrally (i.c.v.). Epibatidine and epiboxidine were the most potent agonists tested, whereas acetylcholine and the alpha7*-selective compounds 3-(2,4-dimethoxybenzylidene)-anabaseine (GTS-21) and anabasine, were the least potent. Nicotine-induce...
neuroleptic malignant syndrome (nms) is a rare fatal medical complication that occurs as a result of dopaminergic receptor blockage in the caudate at the termination of the nigrostriatal pathways (1), and may occur at any time following consumption of dopamine antagonists. this disorder also occurs in cases of sudden discontinuation of dopamine agonists and antagonists (2,3). some studies have ...
