title: Treatment with dihydroethidium reduces infarct size after transient focal cerebral ischemia in mice.
abstract: A transient focal ischemia model with C57Bl/6 mice was used to investigate whether dihydroethidium is neuroprotective. Different doses (25, 50, 100 mg/kg body weight) were used for pretreatment and the lowest effective dose was used for delayed treatment 1 and 2 h after reperfusion. Our results demonstrate that all the doses used for treatment reduced infarct volume. We conclude that dihydroethidium is neuroprotective by reducing superoxide in mice after stroke.
