Heat-sensitive moxibustion has neuroprotective effects against focal cerebral ischemia/reperfusion injury, however its mechanism of action remains unclear. In this study, rat models of focal cerebral ischemia/reperfusion injury were treated with suspended moxibustion at acupoint Dazhui (DU14) for 35 minutes. Results showed that suspended moxibustion decreased infarct volume, reduced cortical my...

Recent evidence has shown crucial roles for cell-adhesion molecules in inflammation-induced rolling, adhesion, and accumulation of neutrophils in tissue. Intercellular adhesion molecule-1 (ICAM-1) is one of these adhesion molecules. Previous studies have shown marked reduction in the size of infarction after focal cerebral ischemia by depletion of granulocytes and administration of the antibody...

We describe a patient who experienced focal cerebral and brainstem ischemia in the setting of postpartum eclampsia. Cerebral angiography showed spasm of large- and medium-caliber arteries. This case provides rare documentation that vasospasm may account for cerebral ischemia in eclamptic women with focal signs. This observation suggests that in such patients cerebral angiography may be informat...

We investigated the temporal threshold for focal cerebral infarction in the spontaneously hypertensive rat The right middle cerebral artery and common carotid artery were occluded for 0,1 ,2 ,3 ,4 , or 24 hours, and all the animals were sacrificed 24 hours after the onset of ischemia. Cortical infarct volumes and edema volumes were quantified in serial frozen sections of hematoxylin and eosin-s...

Lipoxin A4 can alleviate cerebral ischemia/reperfusion injury by reducing the inflammatory reaction, but it is currently unclear whether it has a protective effect on diabetes mellitus complicated by focal cerebral ischemia/reperfusion injury. In this study, we established rat models of diabetes mellitus using an intraperitoneal injection of streptozotocin. We then induced focal cerebral ischem...

AIM NKN reduces brain edema, neuronal death and neurological deficits in rats after cerebral ischemia. In the present study, we investigated whether NKN was effective on brain injury in cerebral ischemia rats. MATERIAL AND METHODS The middle cerebral artery occlusion (MCAO) model was used to produce experimental cerebral ischemia in adult male Wistar rats. The activity of SOD ...

BACKGROUND The authors' previous study demonstrated that a clinical antiarrhythmic dose of lidocaine, when given before ischemia, is neuroprotective in a rat model of transient focal cerebral ischemia. In this study, the authors investigated whether the administration of this dose of lidocaine, when delayed until 45 min after the onset of ischemia, also reduces ischemic brain injury. METHODS ...

BACKGROUND AND PURPOSE Angiotensin-converting enzyme inhibitors have been shown to protect against stroke in hypertensive rats and to improve neurological outcome after cerebral ischemia in normotensive rats. The present study was designated to test the hypothesis that blockade of brain AT(1) receptors improves the recovery from focal cerebral ischemia and reduces expression of AP-1 transcripti...

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 ...

Neurotrophin-3 (NT-3) is a neurotrophic factor that mainly binds to the tyrosine kinase C (trkC) receptor. NT-3 has been shown to have neuroprotective effects in focal cerebral ischemia. Exercise also has ability to induce functional recovery in focal cerebral ischemia. However, the relationship between NT-3, its receptor trkC, and exercise has not been revealed. In this study, we assessed the ...
