Hyperglycemia exacerbates focal ischemic brain damage supposedly through various mechanisms. One such mechanism is oxidative stress involving reactive oxygen and nitrogen species (RONS) production. Nitrones attenuate oxidative stress in various models of brain injury. Sodium 2-sulfophenyl-N-tert-butyl nitrone (S-PBN) can be

The relative roles of the superoxide and hydroxyl radicals in oxidative stress-induced neuronal damage were investigated using organotypic hippocampal slice cultures. Cultures exposed to 100 microM duroquinone, a superoxide-generating compound, for 3 h developed CA1-selective lesions over a period of

The production of oxygen free radicals after perinatal hypoxia-ischemia is thought to play a critical role in the pathogenesis of the brain injury. Administration of anti-oxidants may thus be neuroprotective. The aim of the present study was to investigate the

The status epilepticus (SE) induced in rats by lithium-pilocarpine (Li-pilo) shares many common features with soman-induced SE including extensive limbic neuropathology. Reactive oxygen species are hypothesized to play a role in the SE induced neuropathology and we propose that the

There is substantial evidence implicating excitotoxicity and oxidative damage in the pathogenesis of Huntington's disease (HD). We therefore examined whether the antioxidants 2-sulpho-tert-phenyibutyinitrone (S-PBN) and alpha-lipoic acid could exert neuroprotective effects in transgenic mouse models of HD. S-PBN showed no
