The selectin family of glycoproteins facilitates the early phase of polymorphonuclear leukocyte adhesion to the endothelial cell and, thus, may promote ischemic cell damage. To evaluate E-selectin in the pathogenesis of focal cerebral ischemia and reperfusion injury, we cloned rat E-selectin cDNA and measured the temporal profiles E-selectin mRNA (Northern blot) and protein (immunohistochemistr...

Large body of evidences has indicated that the renin – angiotensin system (RAS) and its effector peptide Angiotensin II may be involved in the pathophysiology of stroke. Previous studies showed that preischemic RAS inhibition reduced brain injury but effects of post-ischemic RAS inhibition on ischemic/reperfusion injuries have not completely been elucidated. Therefore, the present study has inv...

CORONARY HEART DISEASE is the leading cause of death in the Western world and represents one of the major burdens on healthcare systems today. Targeting those strategies that limit the damage sustained as a result of a lethal ischemic insult has been a major goal for many years. One of these strategies, termed ischemic preconditioning, in which brief nonlethal episodes of ischemia protect the m...

Reperfusion of ischemic myocardium is crucial for salvaging myocardial cells from ischemic cell death. However, reperfusion itself induces various deleterious effects on the ischemic myocardium. These effects, known collectively as reperfusion injury, comprise stunned myocardium, reperfusion-induced arrhythmia, microvascular reperfusion injury, and lethal reperfusion injury. No approach has pro...

PURPOSE To evaluate effects of ischemic preconditioning and Cilostazol on muscle ischemia-reperfusion injury. METHODS Male Wistar rats were submitted to muscle ischemic and reperfusion injury (4h of the left common iliac artery occlusion followed by 1h of reperfusion). Five experimental groups were constituted: Control group (n=4); Ischemia-Reperfusion (IR, n=5); Ischemic preconditioning grou...

BACKGROUND AND PURPOSE Most experimental models of cerebral ischemia use mechanical methods of occlusion and reperfusion. However, differences between mechanical reperfusion versus clot thrombolysis may influence reperfusion injury profiles. In this study we compared blood flow recovery, blood-brain barrier (BBB) permeability, and matrix metalloproteinase-9 (MMP-9) expression in cortex after me...

The present study has been designed to pharmacologically investigate the role of phosphoinositide 3-kinase in ischemic postconditioning-induced reversal of global cerebral ischemia and reperfusion-induced behavioral dysfunction in mice. Bilateral carotid artery occlusion for 10 min followed by reperfusion for 24 h was employed in the present study to produce ischemia and reperfusion-induced cer...
