[Effect of ionizing radiation on the kinetic parameters of rat cerebral cortex Na, K-ATPase]

A study was made of the effect of ionizing radiation of 10.3 and 180.6 mC/kg on kinetic parameters of the processes of activation of Na,K-ATPase of rat brain cortex by Mg-ATP-substrate and Na+ and K+ ions. The obtained results prompt an assumption that a conformational rearrangement occurs under the effect of ionizing radiation which is not identical after relatively small and lethal radiation doses.
