ischemia-reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. ischemia-reperfusion brain injury initiates an inflammatory response involving the expression of adhesion molecules and cytokines. twenty–four male wistar rats (250-300 g body wt) were used in this study. the animals were divided into four groups of 6 rat...

INTRODUCTION Cerebral ischemia and reperfusion causes physiological and biochemical changes in the neuronal cells that will eventually lead to cell damage. Evidence indicates that exercise reduces the ischemia and reperfusion-induced brain damages in animal models of stroke. In the present study, the effect of exercise preconditioning on brain edema and neurological movement disorders following...

Background: Erythropoietin (EPO) is known as a regulating hormone for the production of red blood cells, called erythropoiesis. Some studies have shown that EPO exerts some non-hematopoietic protective effects on ischemia-reperfusion injuries in myocytes. Using echocardiography, we evaluated the effect of EPO infusion on reducing ischemia-reperfusion injuries and improvement of the cardiac func...

introduction: this study was aimed to investigate the effects of postconditioning by natural honey on cardiac arrhythmias in the ischemic isolated rat heart. methods: male wistar rats were divided into four groups then anesthetized by sodium pentobarbital. the animal hearts were removed and quickly mounted on a langendorff apparatus and perfused under constant pressure by a modified krebs-hense...

Safranal is a monoterpene aldehyde found in saffron (Crocus sativus L.) petals. It has been previously reported that safranal has a wide range of activities such as antioxidant and anti-inflammatory effects. In this study, we examined the effect of safranal on brain injuries in a transient model of focal cerebral ischemia. Transient focal cerebral ischemia was induced by middle cerebral artery ...

BACKGROUND Nitric oxide synthase (NOS) activity is increased during hypertension and cerebral ischemia. NOS inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (BBB) disruption and cerebral edema formation during stroke in acute hypertension. Here, we investigated the role of NOS inhibition in progression of edema formation and BBB di...

Objective: Ischemia-reperfusion (I-R) injury is defined as the paradoxical exacerbation of cellular dysfunction and death following restoration blood flow to ischemic tissues. In our study, it was aimed examine potential DNA effects liver IR with an experimental animal model. Material Methods: modeling done seven male New Zealand rabbits. Blood samples were taken before model, 30 minutes after ...
