Objective To investigate the dynamic changes of ATP content in rat cerebral cortex after transient ischemia followed by reperfusion and the relationship between the change of energy and the recovery of neural function.Methods The rats were subjected to 10 min of middle cerebral artery occlusion (MCAO). At the time point of 0 h, 1 h, 3 h, 6 h, 12 h, 24 h and 72 h after reperfusion, ATP contents of frontal and parietal cortex were measured by capillary zone electrophoresis.Results At the end of 10 min ischemia, ATP content fell dramatically to less than 20% of the control level. After reperfusion, ATP content recovered gradually. After 1 h, 3 h, 6 h and 12 h of reperfusion, ATP content returned to 70.5%, 65.7%, 84.8% and 86.9% of the control level ( P=0.052, 0.030, 0.332 and 0.491). From 24 h on until 72 h after reperfusion, ATP content decreased again, reaching half of the control level ( P=0.003 and P=0.023). After 10 min ischemia, limb function recovered gradually and completely at last. From 24 h on until 72 h after reperfusion, unwillingness of action and eating was found.Conclusions The recovery of cellular energy system function is delayed even though the reperfusion is in time after transient cerebral ischemia. Furthermore, secondary failure of cellular energy system function occurrs with the reperfusion proceeding. These phenomena are probably responsible for the delayed recovery of neural function after cerebral ischemia in spite of reperfusion.
