Abstract
Hipoxia-iskemia neonatala gaitz komuna da gaur egun (jaioberrien % 0,01-0,1), oxigeno eta glukosaren fluxuaren etenak sortzen duena. Azken urtetako aurrerakuntza pediatrikoak ugariak izan badira ere, hipoxia-iskemia jasaten duten umeek heriotza edo behin betiko ondorio larriak pairatzen dituzte, hala nola, garun-paralisia, epilepsia eta adimen-atzeratasuna. Lan honen helburua resberatrola eta azido dokosahexanoikoa antioxidatzaileek hipoxia-iskemiak sortutako burmuin-kaltean duten efektu neurobabeslea aztertzea da, hipokanpoko zelulen kaltea, astrogliosi errekatiboa, oligondendrozitoen bideragarritasuna eta memoria balioztatuz, horretarako Rice-Vannucci eredua erabiliko dugularik arratoietan kaltea eragiteko.
One of the most common causes of mortality and morbidity in children is perinatal hypoxia-ischemia, so new and more effective neuroprotective strategies are urgently required, in order to minimize as much as possible the neurological consequences of this encephalopathy. In this sense, interest has grown in the neuroprotective possibilities of antioxidants. The aim of the present work was to evaluate the possible neuroprotective effect of resveratrol and docosahexanoic acid antioxiants in hypoxic-ischemic brain injury in neonatal rats, determining hippocampal cell damage, reactive astrogliosis, oligodendroglial injury and long-term behavioral consequences, using the Rice-Vannucci experimental model.
