[Postradiation changes in the system of active transport of ions in the CNS. Analysis of the cation centers of Na,K-ATPase].
A study was made of the influence of ionizing radiation of 0.31 C/kg on the kinetic parameters showing the activity of brain Na, K-ATPase preparation to be a function of ion-regulator concentration. The use of the new method for the analysis of the enzyme cation centers permitted to estimate that whole-body irradiation of rats with the above dose did not cause in vitro a substantial change in the pattern of Na, K-ATPase activation by Na and K ions.
