Minimizing myocardial ischemia-reperfusion injury has broad clinical implications and is a critical mediator of cardiac surgical outcomes. "Ischemic injury" results from a restriction in blood supply leading to a mismatch between oxygen supply and demand of a sufficient intensity and/or duration that leads to cell necrosis, whereas ischemia-reperfusion injury occurs when blood supply is restore...

background & target: ischemia reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. in this study, the effect of pentoxyfylline on bcl2 gene expression changes and cell injury in kidney of rat following ischemia reperfusion were evaluated.methods: in this experimental study, 20 male wistar rats with average weight of...

Background and purpose: Damage caused by ischemia/reperfusion (I/R) is one of the major causes of liver failure during surgeries. Endothelin as the main vasoconstrictor has two receptors; ETA and ETB. Increased number of ETB during ischemia-reperfusion, reduces tissue damages by sinusoidal dilation. This study investigated the effects of dexamethasone against liver endothelial glycocalyx injury...

    Background & Aim: Occlusion of organs artery results in ischemia and the opening of occluded artery leads to tissue lesion identified as reperfusion injury(RI). Oxygen-derived free radicals seem to be involved in the reperfusion injury. In this experimental study the effects of 5-aminosalicylic acid(5-ASA), a prescribed drug for ulcerative colitis, was assessed. 5-ASA is a potent scavenger ...

Background: It has been reported that the chronic oral administration of garlic homogenate protected the rat heart from in vitro ischemic reperfusion injury. However, the biological effects of garlic juice on the heart are expected to be different from oral administration of it. Objective: the present study was designed to investigate the effect of garlic juice on the isolated rat heart in is...

Introduction: Arterial hypertension is one of the causes of stroke, and as one of the vasculotoxic conditions intensifies ischemic stroke complications. The aim of the present study was to analyze the effects of short-term cerebral hypertension on ischemia/reperfusion injury and pathogenesis of ischemic stroke. Methods: The experiments were performed on three groups of rats (N=36) Sham, cont...

objective(s): carthamus tinctorius l. (ct) or saffloweris widely used in traditional chinese medicine. this study investigated the effects of ct extract (cte) on ischemia–reperfusion (i/r) brain injury and elucidated the underlying mechanism. materials and methods: the i/r model was conducted by occlusion of both common carotid arteries and right middle cerebral artery for 90 min followed by 24...
