Objective To observe the effect of ischemic preconditioning on mitochondrial function after cerebral ischemic reperfusion in gerbils.Methods Global cerebral ischemia model was made by occlusion of bilateral carotid arteries in gerbils (ischemia for 20 min and reperfusion for 30 min). Gerbils were divided into three groups-preischemia, mo del and sham operation. Gerbils in preischemia group were undergone two times (each 2 min) transient ischemic preconditioning (48 h interval). The mitochondrial respirat...
