Abstract
A mitochondria-targeted antioxidant, Mito Vitamin E (MitoVit E), has previously been shown to prevent mitochondrial oxidative damage. The aim of this study was to investigate the effect of MitoVit E on neuronal survival in the rat striatum after acute perinatal hypoxia-ischemia. Continuous striatal infusion with 4.35 microM, 43.5 microM, or 148 microM of MitoVit E before, during, and after hypoxia-ischemia was not neuroprotective for striatal medium-spiny neurons. Pre- or posttreatment with 435 microM MitoVit E was neurotoxic. These results suggest that MitoVit E is not significantly neuroprotective for striatal medium-spiny neurons after acute perinatal hypoxic-ischemic brain injury. The results also suggest that mitochondrial oxidative damage does not contribute significantly to the death of striatal medium-spiny neurons after perinatal hypoxia-ischemia.Entities:
