title: DTNB inhibits calcium response of rat brain cortical slices to anoxia of various duration.
abstract: The effects of DTNB on changes in intracellular Ca(2+) content in slices of rat cortex induced by 2- or 10-min anoxia were studied fluorometrically. DTNB (200 microM) prevented excessive intracellular Ca(2+) accumulation during and after 10-min anoxia and moderate increase in Ca(2+) content induced by 2-min anoxia. Our results suggest that redox sites of NMDA receptors participates in both pathogenic and adaptive Ca(2+)-mediated processes activated by anoxia.
