title: [Oxygen consumption and cytochrome oxidase activity of muscle tissue from the limbs of axolotls following restoration of regenerative capability suppressed by x-ray irradiation].
abstract: The intensity of oxygen consumption and the activity of cytochrome oxidase have been studied in the homogenate, mitochondria and nuclei of the limb muscle tissue in axolotls after the suppression of regenerative ability by X-irradiation and its experimental restoration. Under the suppression of regenerative ability, the oxygen consumption was inhibited. The cytochrome oxidase activity in the homogenate and mitochondria decreased and in the nuclei remained at the same level or even increased as compared with the intact limb. Under the restoration of regenerative ability, the intensity of respiration of the homogenate and mitochondria increased and this increase was accompanied by the increase of the cytochrome oxidase activity. The activity of cytochrome oxidase in the nuclei did not change at the stage of blastema and sharply fell at the stage of formed limb.
