How long is too long for cerebral cooling after ischemia in fetal sheep?
Therapeutic hypothermia can partially reduce long-term death and disability in neonates after hypoxic-ischemic encephalopathy. The aim of this study was to determine whether prolonging the duration of cooling from 3 days to 5 days could further improve outcomes of cerebral ischemia in near-term fetal sheep. Fetal sheep (0.85 gestation) received 30 minutes bilateral carotid artery occlusion foll...
متن کاملSurvival of rabbits after prolonged cerebral ischemia.
Cerebral ischemia was produced by a combination of vascular occlusion and mild systemic hypotension in 2 groups of rabbits. Arterial blood pressure, arterial pH, arterial blood gases, blood glucose and PCV were monitored and recorded before, during and for 3 hours after reperfusion. Return of EEG activity, vasomotor control, spontaneous ventilation and corneal reflex were also recorded. At 4, 8...
متن کاملReversible cytotoxic cerebral edema in cerebral fat embolism.
We present a case of cerebral fat embolism (CFE) that demonstrated evidence of diffuse white matter cytotoxic edema on diffusion-weighted magnetic resonance imaging, in addition to punctate hyperintensities on T2-weighted and diffusion-weighted imaging. The case suggests that CFE represents a combination of occlusive arteriolar disease and secondary neurotoxicity.
متن کاملInhibition of nitric oxide synthase activity improves focal cerebral damage induced by cerebral ischemia/reperfusion in normotensive rats
Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...
متن کاملErythropoietin prevents neuronal apoptosis after cerebral ischemia and metabolic stress.
Erythropoietin (EPO) promotes neuronal survival after hypoxia and other metabolic insults by largely unknown mechanisms. Apoptosis and necrosis have been proposed as mechanisms of cellular demise, and either could be the target of actions of EPO. This study evaluates whether antiapoptotic mechanisms can account for the neuroprotective actions of EPO. Systemic administration of EPO (5,000 units/...
