Ketone bodies metabolism during ischemic and reperfusion brain injuries following bilateral occlusion of common carotid arteries in rats.

Purpose: To evaluate the in vivo alterations on ketone bodies metabolism after cerebral ischemia/reperfusion through an experimental model of brain ischemia induced by simple occlusion of common carotid arteries (CCAs) in Wistar rats.

Methods: Forty-eight male Wistar rats were randomly distributed on two groups (S - Sham; T - Test) and further redistributed into four times sets of study. After bilateral occlusion of CCAs for 30 min, the animals of group T were allowed reperfusion for 0, 5, 10 and 15 min.
