Background: Numerous studies have shown the protective effects of saffron against oxidative damage in a global model of cerebral ischemia, but its effects on brain edema and oxidative ischemic injury in focal ischemic stroke are not completely understood. Therefore, this study was designed to investigate the effects of saffron on brain edema, infarct volume, antioxidant enzyme activity (glutath...

Objective(s): Some histopathological alterations take place in the ischemic regions following brain ischemia. Recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. Here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...

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...

aim: oxidative stress plays a crucial role in the pathophysiology of ischemic stroke. since water-solublefullerene derivatives act as the potent scavenger of oxygen free radicals in biological systems, we aimedto investigate the possible protective effects of fullerol nanoparticles on brain infarction and edema intransient model of focal cerebral ischemia in rat.materials & methods: experiment ...

Introduction: Cytokines production as one of the inflammatory pathways in CNS is responsible for most brain damages following ischemia. On the other hand, during inflammation and brain ischemia, most of the renin- angiotensin components (RAS) increase locally. While it is established that blockade of RAS especially AT1 receptors has a protective effect on ischemia, the interaction of cytokines ...

pervious studies have shown that pentoxifylline (ptx) has beneficial effects in reduction of stroke and brain trauma injuries in experimental animals. however, there is very little and controversial information about the effect of ptx on brain edema in cerebral ischemia. therefore, the aim of this study was to determine the effects of different doses of ptx on brain edema and neurological motor...

traumatic brain injury (tbi) is one of the serious neurodisorders commonly caused by car accidents and sports. preventive measures are highly recommended to reduce the risk and number of tbi cases. after tbi, the primary injury to the brain initiates a secondary injury process that spreads via multiple molecular mechanisms in the pathogenesis of tbi. many studies in animals using cdna microarra...

Background: Unit of p65 is one of the subunits of NF-κB and its phosphorylation by stress oxidative causes activation of NF-κB. The aim of present study was to investigate the effects of adenosine injection after brain ischemia reperfusion injury on gene expression of NF-κB /p65 and Reactive Oxygen Species (ROS) in hippocampus tissue of male wistar rats. Methods: 40 male wistar rats were rando...
