Abstract
Changes in the energetic metabolism in the cortex were
examined in bemegride-kindled rabbits. A reliable
decrease in the ATP and an increase in the AMP
contents in the cortical tissues as well as low ATP/AMP
and energetic charge coefficients have been found
after kindling the rabbits for 14 and 30-days as compared
to the control groups of animals. Considerable
disorders in the oxidative phosphorilation in the mitochondria
of the cortical tissues have been determined
after the succinate and glutamate oxidation: a decrease
in the oxygen utilization rate at V 3 active metabolic
state, lowering the respiratory control coefficient and
the disscociation between phosphorilation and oxidation.
Those desorders were more expressed after
glutamate oxidation as compared to a succinate one.
In addition, it has been determined that oxygen utilization
at V 2 state was reliably decreased; both coefficient
of energetic production and ATP-ase reserve activity lowered.
