Research Paper: Optimization of Transient Focal Cerebral Ischemia Model by Middle Cerebral Artery Occlusion
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...
متن کاملProtective Effects of Enriched Environment Against Transient Cerebral Ischemia-Induced Impairment of Passive Avoidance Memory and Long-Term Potentiation in Rats
Introduction: Enriched Environment (EE), a complex novel environment, has been demonstrated to improve synaptic plasticity in both injured and intact animals. The present study investigated the capacity of an early environmental intervention to normalize the impairment of passive avoidance memory and Long-Term Potentiation (LTP) induced by transient bilateral common carotid artery occlusion (2-...
متن کاملProtective effect of α-terpineol against impairment of hippocampal synaptic plasticity and spatial memory following transient cerebral ischemia in rats
Objective(s): Cerebral ischemia is often associated with cognitive impairment. Oxidative stress has a crucial role in the memory deficit following ischemia/reperfusion injury. α-Terpineol is a monoterpenoid with anti-inflammatory and antioxidant effects. This study was carried out to investigate the effect of α-terpineol against memory impairment following cerebral ischemia in rats. Materials a...
متن کاملThe role of nitric oxide in the protective action of remote ischemic per-conditioning against ischemia/reperfusion-induced acute renal failure in rat
Objective(s): We investigated the role of nitric oxide (NO) in the protective effects of remote ischemic per-conditioning (rIPerC) on renal ischemia/reperfusion (I/R) injury in male rats. Materials and Methods: I/R treatment consisted of 45 min bilateral renal artery ischemia and 24 hr reperfusion interval. rIPerC was performed using four cycles of 2 min occlusions of the left femoral artery an...
متن کاملThe effects of gallic acid on pain and memory following transient global ischemia/reperfusion in Wistar rats
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...
