Time course of renal ischemia/reperfusion and distance organ; lung dysfunction in male female rats

background: proanthocyanidin is a potent bioactive antioxidant naturally occurring in grape seed and acts as reactive oxygen species (ros) scavenger. the aim of this study was to investigate the effects of proanthocyanidinin in experimental ovarian torsion injury.   methods : twenty four rats were randomly divided into three groups (n=8). group 1: the laparotomy group, group 2: ovarian torsion ...

objective (s) porin is a mitochondrial outer membrane channel, which usually functions as the pathway for the movement of various substances in and out of the mitochondria and is considered to be a component of the permeability transition (pt) pore complex that plays a role in the pt. we addressed the hypothesis that porin interacts with other mitochondrial proteins after ischemic injury. mater...

objective(s):ischemia is described as organs and tissues are destitute of oxygen due to decreased arterial or venous blood flow. many mechanisms play role in cell death happened as a consequence of a new blood flow is needed for both cell regeneration and to clean toxic metabolites during ischemia and later. lung damage induced by ischemia/reperfusion (i/r) is a frequent problem in lung transpl...

Objective: The present study investigated the effects of a local Thai vegetable, Tiliacora triandra (Colebr.) Diels, also known as Yanang, against cerebral ischemia/reperfusion injury in mice. Materials and Methods: Thirty male ICR mice were divided into three experimental groups of BLCCAO + 10% Tween 80, BLCCAO + T. triandra 300 mg/kg, and BLCCAO + T. triandra 600 mg/kg. Cerebral ischemia/repe...

Objective(s):Acute kidney injury (AKI), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  Renal ischemia-reperfusion, one of the main causes of AKI, is of particular importance in the setting of kidney transplantation. Materials and Methods: Sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

The objective of the present study was to directly visualize ectopic activity associated with ischemia-reperfusion and its progression to arrhythmia. To accomplish this goal, we employed a two-dimensional network of neonatal rat cardiomyocytes and a recently developed model of localized ischemia-reperfusion. Washout of the ischemia-like solution resulted in tachyarrhythmic episodes lasting 15-2...

The purpose of this study was to develop an isolated tissue model in which arrhythmic activity could be generated in response to conditions encountered in ischemia followed by reperfusion, and in which intracellular recordings could be used to identify and study arrhythmogenic mechanisms. Isolated canine Purkinje fiber-papillary muscle preparations were superfused with modified Tyrode's solutio...

Introduction: Oxidative stress plays a crucial role in the impairment of synaptic plasticity following cerebral ischemia which ultimately results in memory dysfunction. Hence, application of antioxidant agents could be beneficial in the management of memory deficit after brain ischemia. Minocycline is a tetracycline antibiotic with antioxidant effect. The main objective of this work was to asse...
