background: simvastatin is a widely used medication in cardiac care. here we evaluate the role of atp sensitive potassium (katp) channels in simvastatin induced renal protection after renal ischemia/reperfusion (i/r) injury. methods: a total of 81 male wistar rats, were treated with simvastatin (10 and 20mg/kg/day gavage, one week). some groups received glibenclamide (katp channel inhibitor ...
Background & Aim: Renal dysfunction due to ischemia-reperfusion (I/R) injury is a common problem following renovascular surgery or kidney transplantation. There is a lot of emerging evidence that statins, which are HMG-COA reductase inhibitors, have renal protective effects against ischemia-reperfusion injury,but the exact mechanism of their protective effect has not been detected properly....
Background: Simvastatin is a widely used medication in cardiac care. Here we evaluate the role of ATP sensitive potassium (KATP) channels in simvastatin induced renal protection after renal ischemia/reperfusion (I/R) injury. Methods: A total of 81 male Wistar rats, were treated with simvastatin (10 and 20mg/kg/day gavage, one week). Some groups received glibenclami...
Improved survival among transfusion dependent thalassemia patients in recent years has led to the manifestation of morbidities such as renal dysfunction. Renal injury is still an underestimated complication in β thalassemia major patients. Chronic anemia, iron overload due to repeated transfusion, and specific iron chelators are the main factors in pathogenesis of renal dysfunction in β thalass...
Introduction: The aim of this study was to investigate the effect of angiotensin II (Ang II) and losartan injections into paraventricular nucleus (PVN) on renal ischemia-reperfusion injury. Methods: After right nephrectomy in male rats, a cannula was inserted into the right PVN. One week later, renal ischemia-reperfusion (IR) injury was induced by clamping the left renal artery for 45 min, a...
Background: Renal ischemia reperfusion (RIR) injury is a common clinical syndrome that affects renal function and significantly increases morbidity and mortality. Hydrogen sulfide (H2S) is an endogenously gaseous mediator that exhibits many cytoprotective effects. Recently, studies have shown that H2S have opposite effects in different doses. Therefore, in the current study we investigated the ...
objective(s):there are a few previously reported studies about the effect of nigella sativa oil on renal ischemia-reperfusion injury (iri). the aim of the present study was to test the hypothesis whether pre- or post-treatment with n. sativa hydroalcoholic extract (nse) would reduce tissue injury and oxidative damages in a clinically relevant rat model of renal iri. materials and methods: ir...
background: renal ischemia reperfusion (ir) injury has been a major source of concern during the past decades and angiotensin converting enzyme (ace) inhibitors have been successfully used to prevent this injury. there have been some controversial reports about the involvement of katp channels in the mechanism of action of ace inhibitors. in this study, we examined the effect of katp channel bl...
conclusions the pattern of pretreatment with o2 could change this potential and highly protective strategy against cp-induced nephropathy to an ineffective or even mildly deteriorating one. therefore, o2 administration before cp injection to patients with cancer, for therapeutic purposes or as a preconditioning approach, should be performed and investigated with caution until exact effects of d...
introduction: ischemia-reperfusion (ir) injury involves a complex, interrelated sequence of events. generation of reactive oxygen species (ros) especially superoxide anion, during ir is reported. the present study was designed to investigate the effect of mn (iii) tetrakis (4- benzoic acid) porphyrin (mntbap), an active, stable, nontoxic, and cell permeable sod (super oxide dismutase) mimetic i...
