Abstract:
Objective To study the effect of local mild hypothermia on AKT protein expression after rats focal cerebral ischemia-reperfusion injury.Methods By using the model of rat focal cerebral ischemia-reperfusion injury,the middle cerebral arteries(MCA)of SD rats were occluded for 2 h,and reperfused for2h,12h,24h,72h.Immunohistochemical analysis was used to detect expression of AKT.Results AKT expressed after ischemia 2h,the expression was significantly increased after ischemia reperfusion with peak expression at 72h in model group on normal temperature.In mild hypothermia group,the AKT expression was higher than that in normal temperature group when at the same time point.Conclusion Brain hypoxia-ischemia could induce the expression of AKT.Mild hypothermia could promote the expression of AKT.The expression of AKT could be one of the protected way of brain hypoxia-ischemia.
