Abstract
Using phorbol 12,13-dibutyrate (PDBu) autoradiography, we investigated the effect of hypothermia or protein kinase C (PKC) activation in rat brain 2 h after focal ischemia. In normothermia, a significant increase of PDBu binding was observed in ischemic brain. Hypothermia suppressed the increase of PDBu binding in degree and extent. These observations suggest that intraischemic hypothermia attenuates the activation of PKC, and this may in part be participate in the protective effect of hypothermia.
