title: The effect of propofol on increased superoxide concentration in cultured rat cerebrocortical neurons after stimulation of N-methyl-d-aspartate receptors.
abstract: The neuroprotective properties of propofol may be because of its action as an antioxidant. To investigate whether propofol reduces the N-methyl-D-aspartate-induced increase in superoxide anion levels, the fluorescence of dihydroethidium acetoxymethylester, as an indicator for cellular superoxide concentration, was measured in cultured rat forebrain neurons.
