One of the newest methods to reduce cerebral ischemia damages is cell therapy. The aim of this study is to evaluate the effect of Sertoli cell transplantation on ischemia-induced injuries in animal models of stroke. Rats were divided into four groups: transplant+ischemia, ischemia, sham, and control. Sertoli cells were separated from the other testis of rats and cultured. Unilateral Sertoli cel...
objective(s): morphine dependence (md) potently protects heart against ischemia reperfusion (ir) injury through specific signaling mechanisms, which are different from the pathways involved in acute morphine treatment or classical preconditioning. since opioid receptor density changes post cerebral ischemia strongly correlated with brain histological damage, in the present study, we tried to el...
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...
Introduction: Although exercise is an effective strategy for preventing and treating stroke, the extent of this effect seems to depend on when exercise begins. Apoptosis plays a critical role after stroke. However, it is unclear whether early exercise inhibits apoptosis after stroke? The aim of this study was to determine the effect of eight weeks of early aerobic training after stroke inductio...
Introdution: This study aimed to investigate the effect of a period of high-intensity interval training on regulation signaling of factors involved in vascular changes following myocardial ischemia. Methods: 28 rats (200-250 g) were randomly assigned into four groups of sham, ischemia, training, and training-ischemia in this study. Myocardial infarction was performed by closing descending coro...
Objective(s): Stroke poses a crucial risk for mortality and morbidity. Our study aimed to investigate the effect of p-coumaric acid on focal cerebral ischemia in rats. Material and Methods: Rats were randomly divided into four groups, namely Group I (control rats), Group II (ischemia rats), Group III (6 hr ischemia + p-coumaric acid rats) and Group IV (24 hr ischemia + p-coumaric acid rats). C...
Introduction: Cerebral ischemia is one of the most common causes of death in human populations in the industrial communities. The need for animal models is inevitable to study the pathophysiology and treatment of cerebral ischemia in human. The current study aimed at evaluating the strengths and weaknesses of different techniques used to create ischemia in previous studies and optimizing the tr...
background and objective: as one of the widely used drugs, aspirin (acetyl-salicylic acid, asa) plays an important role in stroke treatment and prevention. in a previous study, we demonstrated asa injection at 30 min after ischemia onset is neuroprotective. to determine whether the neurons protected by asa had a normal ultrastructure, hippocampal ca1 pyramidal neurons were examined by transmiss...
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...
Background and objective: Transient global cerebral ischemia leads to neuronal damage in the hippocampus and cerebral cortex which results in learning and memory impairment. Exercise preconditioning helps with neuroprotection against cerebral injuries induced by ischemia. The purpose of the present study was to investigate the effect of exercise preconditioning on tactile learning following glo...
