[Electrogenic activity of Ca2+-ATPase fragments of the sarcoplasmatic reticulum during the early stages of radiation injury].
It is established that local X-ray irradiation of the rabbit hind limb produces a decrease in Ca2+, Mg2+-ATP-dependent formation of electric potentials difference on the membrane of the sarcoplasmic reticulum (SR). These results agree with the observed decrease in the Ca2+-ATPase activity of SR membranes and increase in their electric conduction after irradiation.
