ischemia reperfusion injury (ir injury) is a common problem in clinical conditions. researches have frequently revealed that atp- sensitive potassium (katp) channels and nitric oxide plays a role in protection against ischemic injury in skeletal muscle. the present study aimed at evaluating the possible link between this two pathways. sixty-eight male wistar rats, were pretreated with saline, d...

Abstract Our case describes the reintroduction of diazoxide despite life-threatening pulmonary hypertension in our infant due to lack therapeutic options for congenital hyperinsulinism.

BACKGROUND The mitochondrial K(ATP) channel (mitoK(ATP)) has been implicated as an end effector or trigger of ischemic preconditioning (IP). Although a mitoK(ATP) opener, diazoxide, mimics IP, mechanisms for the cardioprotective action remain unclear. METHODS AND RESULTS We measured Ca2+ transients (CaTs) and mitochondrial inner membrane potential (Deltapsi(m)) with confocal microscopy and th...

Am J Physiol Endocrinol Metab 287: E1202–E1208, 2004. First published August 3, 2004; doi:10.1152/ajpendo.00255.2004.—Prolonged periods of “ -cell rest” exert beneficial effects on insulin secretion from panc...

Growing evidence exists that ATP-sensitive mitochondrial potassium channels (MitoKATP channel) are a major contributor to the cardiac protection against ischemia. Given the importance of mitochondria in the cardiac cell, we tested whether the potent and specific opener of the MitoKATP channel diazoxide attenuates the lethal injury associated with Ca2+overload. The specific aims of this study we...

Background—The mitochondrial KATP channel (mitoKATP) has been implicated as an end effector or trigger of ischemic preconditioning (IP). Although a mitoKATP opener, diazoxide, mimics IP, mechanisms for the cardioprotective action remain unclear. Methods and Results—We measured Ca transients (CaTs) and mitochondrial inner membrane potential ( m) with confocal microscopy and the fluorescent probe...

there are many reports for involvement of atp-sensitive potassium channels in pancreatic, cardiac and vascular smooth muscle cells. this study examined the effect of single doses of k+ channel openers diazoxide, minoxidil and k+ channel blockers chlorpropamide, glibenclamide on serum concentration of aldosterone in male rats. blood samples were obtained 60 minutes after drug treatment and serum...
