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...

objective: it is generally agreed that most of the phenomena observed during brain ischemia and reperfusion can be explained by the damage to membrane structure. oxidative stress is resulted in an imbalance between high consumption of oxygen and low levels of endogenous antioxidants. it is known that gallic acid (ga) is a strong antioxidant. the present study was carried out to evaluate the eff...

An ischemia-reperfusion (I/R) injury of small intestine is a serious and common condition that result the blockage superior mesenteric artery (SMA) because significant clinical problems. This study evaluated effect Mesna on systemic induced by ischemia/reperfusion (IR) in also liver, kidney lung as remote organs. Forty Wistar albino rats were randomly divided into four groups: control, ischemia...

objective: several studies have shown that chichorium intybus l. (c. intybus) which possesses flavonoid compounds has an effective role in treatment of cardiovascular diseases. contractile dysfunction mostly occurs after acute myocardial infarction, cardiac bypass surgery, heart transplantation and coronary angioplasty. the aim of the present study was to investigate the effect of aqueous extra...

background: the aim of this study was to investigate the protective effects of crocin against tissue damages and leukocyte infiltration induced by renal ischemia/reperfusion. methods: in this experimental study, 35 male wister rats weighing 250-300 g were randomly divided into 5 groups; 1. operated controls, but no vessel occlusion was considered and passed during equivalent reperfusion period ...

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 ...

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...
