Many complicated mechanisms are involved in brain ischemia and the role of inflammatory factors in the progression of post-ischemic injury is inevitable. In present study, anti-inflammatory effect of berberine has been investigated in reperfusion injury after acute ischemic stroke. Male Wistar rats weighing 250-270 gr were randomly divided into four cohorts: healthy rats (control, n=20), sham-o...
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 ...
background & objectives: ischemic stroke is the third leading cause of death and disability in most of the human societies. there is no effective treatment due to complexity of the pathophysiological mechanisms. today, more researches are designed to introduce involving factors and new treatment strategies in brain ischemia. the objective of this study is to introduce an experimental model of t...
Protective Effect of Delayed Ischemic Postconditioning on Embolic Stroke Complications in Female Rat
Background & Aims: Ischemic postconditioning, conducted by a series of brief occlusion and release of the bilateral common carotid arteries, has neuroprotective properties in permanent or transient models of middle cerebral artery (MCA) occlusion but its delayed neuroprotective effects in the embolic model of stroke, especially in female rat, have not yet been reported and were investigated ...
Introduction: Stroke is a neurological disease and one of the leading causes of death all over the world. It is also an important cause of disability in people over age over 65. It may be possible to reduce the incidence of cerebral ischemia using antioxidants, followed by inhibition of oxidative and inflammatory mechanisms. Troxerutin is a natural bioflavonoid with antioxidant and anti-inflamm...
Background and Aim: Stroke is one of the most important factors of mortality and disability in the world. Free radicals are produced following ischemic stroke and they play a central role in breaking the blood-brain barrier and causing brain edema formation. The aim of the current study was to evaluate the effect of hydro- alcoholic extract of Origanum vulgare on brain edema and neurologic ...
Background : Brain injury by transient complete global brain ischemia (cardiac arrest) and regional incomplete brain ischemia (ischemic stroke) afflicts a very large number of patients with death or permanent disability. Recent studies suggest that olive extracts suppress inflammation and reduce stress oxidative injury. Methods: The aim of the study was to evaluate the effect of dietary Oli...
The influence of the duration of ischemia on the development and resolution of post-ischemic brain edema (SG method) was studied in anesthetized rats. Edema developed during ischemia and the amount of edema was related to the duration of ischemia (r = 0.843, p less than 0.001). With recirculation to three hours, the major determinant of the amount of edema was still the duration of the precedin...
Mongolian gerbils were observed for the effects of beta-methasone on ischemic brain edema which developed during ischemia or after blood flow restoration. The severity of brain edema was determined by measuring water content of the ischemic cerebral hemisphere, using the wet and dry methods. Sodium and potassium ions were extracted from homogenized brains with 0.75N HNO2 and ion concentration m...
