Reperfusion has the potential to introduce additional injury that is not evident at the end of ischaemia per se, i.e. reperfusion injury. Reperfusion injury is expressed as endothelial and microvascular dysfunction, impaired blood flow, metabolic dysfunction, cellular necrosis, and apoptosis. There is an impressive array of mechanisms contributing to reperfusion injury. Postconditioning, define...
BACKGROUND Remote reperfusion lung injury occurs in patients with vascular occlusion and surgical procedures. Inosine monophosphate (IMP) produced by adenosine monophosphate deaminase (AMPD) 3 is involved in the remote reperfusion injury. The purpose of the present study was to identify whether IMP administration attenuated the remote reperfusion lung injury in a skeletal muscle ischemia-reperf...
BACKGROUND/AIMS Mesenteric ischemia/reperfusion injury induces a systemic response and releases harmful substances that may affect distant organs such as the lung, liver and kidney. We designed this study to determine if curcumin has protective effects against mesenteric ischemia/reperfusion injury and mesenteric ischemia/reperfusion-induced intestinal and distant organ injury. METHODS Forty ...
Cardioprotective therapy and sodium-hydrogen exchange inhibition: current concepts and future goals.
Following acute myocardial infarction (MI), limitation of infarct size is central to long-term outcome (1). Successful reperfusion results in smaller infarct size and a marked reduction in mortality (1,2). However, following fibrinolytic therapy, ischemic myocardial injury continues during the process of clot lysis. Although reperfusion arrests the acute ischemic injury, it may cause further in...
Hepatic ischemia-reperfusion injury is a dynamic process consisting of two stages: ischemia and reperfusion, and triggers a cascade of physiological and biochemical events. Given the important role of microRNAs in regulating gene expression, we analyzed gene expression changes in mouse livers at sham control, ischemia stage, and reperfusion stage. We generated global expression profiles of micr...
Purpose: To investigate the effects of cyclosporine A on renal ischemia-reperfusion injury during transient hyperglycemia in rats. Methods: In a model of ischemia-reperfusion-induced renal injury and transiently induced hyperglycemia by intraperitoneal injection of glucose, 2.5 g.kg-1, Wistar rats were anesthetized with either isoflurane or propofol and received intravenous cyclosporine A, 5...
Objective- This study investigated the effect of amlodipine on intestinal ischemia-reperfusion injury in ratsDesign-Experimental studyAnimals-Fifteen male Sprague-Dawly rats weighing 200-220gProcedure- Rats were randomly divided into 3 groups: IR group (operation with clamping), sham group (operation without clamping), and IRA group (operation with clamping and 5mg/kg amlodipi...
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...
Ischemia/reperfusion injury is a reaction occurring after successful treatment of an acute myocardial infarction or in the setting of solid organ transplantation. After successful reperfusion of a previously occluded vessel or a transplanted organ, an additional loss of otherwise vital cells may occur, the so-called lethal ischemia-reperfusion injury. This lethal reperfusion injury is based on ...
