Ischemic stroke causes the depletion of energy and induces excitotoxicity and neuroinflammation in the brain that results from thrombotic blockage. Cerebral ischemia leads to many types of memory loss, including impairment of working, spatial and object recognition memoreis. Curcumin shows strong anti-oxidoinflammatory activities but it terapathics limited by its low solubility in water and cor...
myocardial ischemia (mi) resulting in infarction is an important cause of mortality and morbidity worldwide. acute ischaemia rapidly impairs myocardial contractile function. myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. hibernation is now thought to be the consequence o...
Background and purpose: Vitamin C and CoQ10 are known as two potentantioxidants. We studied the protective Role of CoQ10 and ascorbic acid against Ischemia-Reperfusion. Finally, we have compared the therapeutic effect of these two together. Materials and methods: 35 male balb-Cwere divided into seven subgroups. Includes five groups: intact, ischemicControl, sham Control and treatment groups wi...
Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be...
Background and purpose: The quality of life in patients with cancer is affected by cognitive changes after chemotherapy. There are different reports about the effect of cyclophosphamide as a chemotherapy agent on cognitive function. So, the present study aimed to investigate the effects of acute and chronic injections of cyclophosphamide on passive avoidance and novel object recognition memory ...
objective: stroke is most important cause of death and disability in adults. the hippocampal ca1 and sub-ventricular zone neurons are vulnerable to ischemia that can impair memory and learning functions. although neurogenesis normally occurs in the dentate gyrus (dg) of the hippocampus and sub-ventricular zone (svz) following brain damage, this response is unable to compensate for severely dama...
Centella asiatica extract on cognition and hippocampal pathology of mild chronic cerebral hypoperfusion (CCH) that was induced by permanent right common carotid artery occlusion (RCO) in rats. Materials and Methods: Sixty-four male Sprague-Dawley rats were randomly divided into four groups of Sham-veh, Sham-C. asiatica, RCO-veh and RCO-C. asiatica, which were further divided into short-term and...
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...
Patient RB became amnesic following an episode of global ischemia that resulted in a bilateral lesion of the CA1 field of the hippocampus. This finding suggested that damage restricted to the hippocampus is sufficient to produce clinically significant memory impairment. To evaluate further the effect of ischemic brain damage on memory, we have developed an animal model of cerebral ischemia in t...
