BACKGROUND Myocardial ischemia and reperfusion lead to impairment of electrolyte balance and, eventually, lethal arrhythmias. The aim of this study was to investigate the effects of pharmacological inhibition of angiotensin-II (Ang-II) production on heart tissue with ischemia-reperfusion damage, arrhythmia, and oxidative stress. MATERIAL AND METHODS Rats were divided into 4 groups: only ischemi...

The purpose of this study was to determine whether exogenous zinc prevents cardiac reperfusion injury by targeting the mitochondrial permeability transition pore (mPTP) via glycogen synthase kinase-3beta (GSK-3beta). The treatment of cardiac H9c2 cells with ZnCl2 (10 microM) in the presence of zinc ionophore pyrithione for 20 min significantly enhanced GSK-3beta phosphorylation at Ser9, indicat...

Lung resection may be complicated by postpneumonectomy pulmonary oedema. Oxidant generation following surgery-induced ischaemia-reperfusion may be responsible. This hypothesis was tested utilizing isolated, in situ, blood perfused rodent lungs subjected to continuous perfusion (control subjects); one lung ventilation followed by pneumonectomy (group 1); or one lung ventilation followed by reinf...

Oxidative stress, a state in which intra- or extracellular oxidant production outweighs the antioxidative capacity, lies at the basis of many diseases. DCFH2-DA (2',7'-dichlorodihydrofluorescein diacetate) is the most widely used fluorogenic probe for the detection of general oxidative stress. However, the use of DCFH2-DA, as many other fluorogenic redox probes, is mainly confined to the detect...

OBJECTIVES This study investigated the effects of melatonin, famotidine, mirtazapine, and thiamine pyrophosphate on ischemia/reperfusion (I/R) injury in diabetic rats and evaluated oxidant and antioxidant marker measurement results. It also examined the effects of the drugs aimed at preventing infertility that may result from I/R injury. MATERIALS AND METHODS Diabetic rats were divided into a...

Hepatic ischemia-reperfusion (I/R) is a common phenomenon during liver surgery, transplantation, infection and trauma which results in damage and necrosis of the hepatic tissue through different pathways. Mechanisms involved in I/R damage are very intricate and cover several aspects. Several factors are involved in I/R-induced damages; briefly, decrease in sinusoidal perfusion and ATP generatio...
