Ouabain prevents loss of autoregulation in rat pial arterioles caused by reoxygenation after a brief hypoxic episode.

abstract：:Induced ketosis may acutely prolong hypoxic tolerance by altering glucose and (or) beta-hydroxybutyrate extraction by the brain. Anesthetized dogs were ventilated and instrumental for arterial and cerebral venous blood sampling, taken during baseline, infusion, test, and recovery periods. Each dog received one of four...

Bodyweight, plasma glucose concentration, total body glucose turnover rate, and glucose pool size were not significantly different between the two groups. This suggests that the premature piglet is capable of maintaining glucose home...
