title: Hypothermia decreases astroglial injury and arachidonate release during combined glucose-oxygen deprivation.
abstract: Hypothermia provides significant protection when initiated during or after cerebral ischemia in vivo. However, the mechanisms producing this protective effect are not known. Astroglial cultures were prelabeled with [3H]arachidonic acid. Hypothermia reduced both cellular injury and release of [3H]-labeled arachidonic acid metabolites during combined glucose-oxygen deprivation. Inhibition of phospholipid degradation may be one of the mechanisms that contributes to the protective effect of hypothermia.
