The level of phosphocreatine (PCr) and the intracellular pH (pHi) of superfused cortical brain slices from adult or 10-day-old rats were monitored using 31P NMR. When the glucose in the superfusing medium was replaced by 3-hydroxybutyrate (3HB), there was a significant reduction in PCr of the adult but not the neonatal slices. The level of PCr of the adult slices was reduced by a greater amount by aglycaemic hypoxia compared with the neonatal brain slices and pHi was decreased by the same amount. After aglycaemic hypoxia, the levels of PCr of the neonatal slices recovered to the same extent when perfused with glucose or 3HB alone or a mixture of glucose and 3HB. The recovery of the PCr was significantly more in the neonatal than the adult brain slices with glucose alone after aglycaemic hypoxia, whereas pHi returned to control levels in both tissue types and with all substrates. The relative recovery of the PCr of the adult slices after aglycaemic hypoxia was the same with either 3HB or glucose. However, if glucose and 3HB were applied together, recovery of PCr was significantly improved compared with glucose alone.
