Anti-nociceptive effect of cimetidine in mice: the role of ATP-sensitive potassium channels
Recent studies have shown that intracerebroventricular administration of cimetidine (CIM) induces anti-nociceptive and anti–inflammatory effects in rats. However, the underlying mechanism of CIM effect has not been determined yet. This study was planned to determine the anti-nociceptive effect of CIM (50 mg/kg, i.p.) in male mice (25-30 g, n = 80) using tail flick test. Also, the role of ATP-se...

متن کاملATP-sensitive potassium channels mediate dilatation of basilar artery in response to intracellular acidification in vivo.
BACKGROUND AND PURPOSE During cerebral ischemia, both hypoxia and hypercapnia appear to produce marked dilatation of the cerebral arteries. Hypercapnia and hypoxia may be accompanied by extracellular and intracellular acidosis, which is another potent dilator of cerebral arteries. However, the precise mechanism by which acidosis produces dilatation of the cerebral arteries is not fully understo...
متن کاملCardiovascular ATP-sensitive potassium channels
Sulfonylurea drugs stimulate endogenous insulin secretion by blockade of ATP-sensitive potassium channels in pancreatic beta cells. These drugs are widely used in the treatment of type 2 diabetes. However, as ATP-sensitive potassium channels also exist in cardiomyocytes and coronary and peripheral arterial vascular smooth muscle cells, sulfonylurea drug usage in theory may cause unwanted cardio...
متن کاملEndothelial biology and ATP-sensitive potassium channels
ATP sensitive potassium (KATP) channels are metabolic sensors with channel activity promoted by decreases in ATP andnor increases in MgADP. The most studied are channels present in cardiac myocytes and pancreatic b cells but KATP currents also exist more widely in a range of tissues and organs [1,2]. The channel is a hetero-octamer comprising four sulphonylurea receptors and four pore-forming i...
