Abstract
The cortical circulation of the baboon has been studied during ischaemia produced by middle cerebral occlusion. Evidence of reactive hyperaemia did not occur in hypercapnia. Metabolic studies as a whole present evidence of increased interference with gaseous metabolism during hypercarbic occlusion, despite raised venous pO(2) during hypercarbia. The significance of these findings is discussed.
摘要
在大脑中动脉闭塞导致缺血期间，对狒狒的皮质循环进行了研究。在高碳酸血症时未出现反应性充血的证据。尽管高碳酸血症期间静脉血氧分压升高，但整体代谢研究表明，在高碳酸血症性闭塞期间，气体代谢受到的干扰增加。讨论了这些发现的意义。
