[Evolution of myocardial glycolysis in perinatal rats].
Glycolysis was assessed in the Langendorff perfused rat heart during the perinatal period. Glucose uptake, lactate production, 14C-glucose incorporation into glycogen, tissue content content of glycogen, lactate and high energy phosphates were measured in the foetus of 21.5 days post coïtum and in the newborn of 1 and 7 days post partum. Glycogen synthesis and anaerobic glycolysis were found to be more active in the foetal heart and to decrease during the first neonatal week.
