The effect of (-)eburnamonine, papaverine and UDP-glucose intracarotid perfusion has been evaluated in the brain of beagle dogs during various conditions of cerebral damage (hypoxia, hypoxia plus incomplete ischaemia, hypoxia plus complete ischaemia), and after 3, 15 or 30 min of the post-hypoxic recovery and recirculation. The behaviour of fuels (glycogen, glucose), of glycolytic pathway intermediates (glucose-6-phosphate, pyruvate) and end-product (lactate), of the pool of labile phosphates (ATP, ADP, AMP, creatine phosphate) and the energy charge potential of the brain were evaluated in the motor area of the cerebral cortex. The different pharmacological effects of (-)eburnamonine, papaverine and UDP-glucose are discussed with regard to the biochemical changes taking place during the physiopathological conditions tested

Abstract

The effect of (-)eburnamonine, papaverine and UDP-glucose intracarotid perfusion has been evaluated in the brain of beagle dogs during various conditions of cerebral damage (hypoxia, hypoxia plus incomplete ischaemia, hypoxia plus complete ischaemia), and after 3, 15 or 30 min of the post-hypoxic recovery and recirculation. The behaviour of fuels (glycogen, glucose), of glycolytic pathway intermediates (glucose-6-phosphate, pyruvate) and end-product (lactate), of the pool of labile phosphates (ATP, ADP, AMP, creatine phosphate) and the energy charge potential of the brain were evaluated in the motor area of the cerebral cortex. The different pharmacological effects of (-)eburnamonine, papaverine and UDP-glucose are discussed with regard to the biochemical changes taking place during the physiopathological conditions tested
