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...

Objective-Ovarian torsion must be diagnosed and treated as much early as possible. The aim of the present study was to investigate effects of interaperitoneal administration of curcumin on ischemia-reperfusion injury in ovaries. Design- Experimental Study Animals- Twent-four healthy female Wistar rats Procedures- Twent-four healthy female Wistar rats weighing approximately 260...

Objective(s): Cerebral ischemia/reperfusion causes complex pathological mechanisms that lead to brain tissue damage. Usnic acid is a lichen secondary metabolite that has many different biological properties including anti-inflammatory and anti-oxidant activities. Therefore, the objective of the current study was to investigate the neuroprotective effects of usnic acid ...

PURPOSE Phosphodiesterase (PDE) III inhibitors have been reported in various cellular protective activities via the cyclic adenosine monophosphate (cAMP) pathway. We investigated the effects of amrinone on ischemia/reperfusion injury and intracellular calcium (Ca2+) handling if utilized as a component of terminal warm blood cardioplegia (TWBCP). METHODS Anesthetized pig hearts were subjected ...

Ischemic and reperfusion injury is a serious condition related to numerous biochemical and electrical abnormalities of the myocardium. It has been repeatedly studied in various animal models. In this study, the production of hydroxyl radicals and electrophysiological parameters were compared in three species. Rat, guinea pig and rabbit isolated hearts were perfused according to Langendorff unde...

OBJECTIVE Ventricular tachyarrhythmias (VTs) occur frequently in patients having long QT syndrome (LQTS) or after acute myocardial ischemia. However, the synergistic effects of ischemia and LQTS on arrhythmia development are unclear. We evaluated the contribution of a prior episode of ischemia on the arrhythmogenicity of the LQTS. METHODS Using a 256-channel optical mapping system, we mapped ...

conclusions pretreatment with epo and application of ipc significantly ameliorated the renal injury induced by bilateral renal ir. however, both treatments attenuated renal dysfunction and oxidative stress in kidney tissues. there were no significant differences between pretreatment with epo or application of ipc. materials and methods twenty four male wistar rats were allocated into four exper...

Objective(s): Gallic acid (GA), a potent anti-oxidant, plays an important role in reducing diabetic induced cardiac disorders. Therefore, the present investigation was purposed to determine the beneficial effect of GA in cardiac arrhythmias during reperfusion in diabetes induced by alloxan. Materials and Methods: Male Sprague-Dawley rats...

We previously demonstrated in rats that noninvasive delayed limb ischemic preconditioning (LIPC) induced by three cycles of 5-min occlusion and 5-min reperfusion of the left hind limb per day for three days confers the same cardioprotective effect as local ischemic preconditioning of the heart, but the mechanism has not been studied in depth. The aim of this project was to test the hypothesis t...
