background: release of vascular endothelial growth factor (vegf) by ovaries in response to hcg administration is one of the main mechanisms of ovarian hyper stimulation syndrome. since dopamine/dopamine receptor2 (dp-r2) pathway activity -mediated by vegf/ vascular endothelial growth factor receptor 2 (vegfr-2) signaling-, is associated with angiogenic events, dopamine agonists were used for th...

Dopamine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [373]) are commonly divided into D1-like (D1 and D5) D2-like (D2, D3 D4) families, where endogenous agonist is dopamine.

introduction: spreading depression (sd) is a propagating wave of depolarization followed by depression of the neuroglial activities and can modulate extracellular dopamine concentrations in the neocortex. it has been shown that the dopaminergic system plays a role in migraine. sd has been suggested as a critical phenomenon in the pathophysiology of migraine. the aim of this study was to investi...

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 pote...

in the present study, interactions of dopamine receptor agonists and antagonists with water swimming stress (wss) on naloxone-induced jumping in morphine-dependent mice were examined. mice were rendered dependent as described in the methods section. the opioid receptor antagonist, naloxone (1 mg/kg), was injected to elicit jumping (as a withdrawal sign). the first group exposed to wss in the pr...

Ventral tegmental area (VTA) dopamine neurons play an important role in reward mechanisms of food intake, and VTA dopamine receptors exist on the terminal of glutamatergic and GABAergic neurons and regulate GABA and glutamate release. To our knowledge, there is no evidence to show that VTA D1 dopamine receptors play a role in regular chow intake. In this paper, the effect of SKF38393, a D1 rece...
