Abstract/OtherAbstract:
Glycolytic substrates and metabolites (glycogen, glucose, glucose-6-phosphate, pyruvate, lactate), tricarboxylic acid cycle intermediates (citrate, alpha-ketoglutarate, succinate, fumarate, malate), related amino acids (glutamate, glutamine, alanine, gamma-aminobutyrate) and energy mediators (ATP, ADP, AMP, creatine phosphate) were evaluated in the cerebral cortex of rats after 5 min of complete compression ischemia as well as after 3, 15 or 30 min of recirculation following 5 min ischemia. The post-ischemic recovery was studied in control animals or in animals treated (30 min before ischemia and during discovery) by intravenous perfusion of vincamine, theophylline, dihydroergocristine and alanine. Interrelated changes of intermediates of the carbohydrate and the amino acid metabolism have been observed. It is concluded that alanine perfusion induced a partial detour of the lactacid anaerobic process towards the succinate-related alactacid cycle, leading to an increase in the cortical gamma-aminobutyrate content. Vincamine and dihydroergocristine acted in the opposite direction.
