Bachground & Objectives: In the brain ischemia, the production of free radicals increases. Salvia is a rich source of antioxidant compounds therefore, in this study we will examine the effects of Salvia extracts on brain edema and score of neurological deficits. Materials & Methods: In this experimental study, 35 male Wistar rats were randomly divided into 5 groups, each containing 7 rats. T...
traumatic brain injury (tbi) is one of the major causes of severe disability and death in the entire world that accidents are mentioned as main factors of it. tbi lead to primary and secondary injuries. primary injuries are created immediately after accidents or bleeding but the secondary injuries are created by complicated process of cellular and molecular responses following primary injury a...
Introduction: Cerebral ischemia and reperfusion causes physiological and biochemical changes in the neuronal cells that will eventually lead to cell damage. Evidence indicates that exercise reduces the ischemia and reperfusion-induced brain damages in animal models of stroke. In the present study, the effect of exercise preconditioning on brain edema and neurological movement disorders followin...
the brain edema is one of remarkable injuries after traumatic brain injuries (tbi). the common treatments for limiting edema are included mannitol, barbiturates, corticosteroids, hyperventilation and central nervous system derange. the most of these treatments for edema is problematic. for example, mannitol can be effective for the short period of time (24 hours) after brain injuries but is not...
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...
brain edema plays an important role in secondary tissue damage following traumatic brain injury (tbi) but the underlying mechanisms are not entirely elucidated. the g protein coupled receptor fm-4 and its ligands, neuromedin s (nms) and neuromedin u (nmu), are expressed in diverse brain areas, and have a variety of roles in nociception, inflammation, and stress but their probable changes after ...
objective: following traumatic brain injury, disruption of blood-brain-barrier and consequent brain edema are critical events which might lead to increasing intracranial pressure (icp), and nerve damage. the current study assessed the effects of aqueous date fruit extract (adfe) on the aforementioned parameters. materials and methods: in this experimental study, diffused traumatic brain injury ...
Background: Angiotensin II (Ang II) has an important role on cerebral microcirculation however, its direct roles in terms of ischemic brain edema need to be clarified. This study evaluated the role of central Ang II by using candesartan, as an AT1 receptor blocker, in the brain edema formation and blood-brain barrier (BBB) disruption caused by ischemia/reperfusion (I/R) injuries in rat. Methods...
