The oxygen-radiation effects on the conservation of radiation injuries during hibernation were studied in frogs exposed to 900 r in a nitrogen atmosphere. Preliminary data indicate morphological changes in the epithelium begin developing after the awakening. Moreover, the radiation injuries are not altered during hibernation but are slowed down, confirming the existence of a radiation conservation mechanism. Experimental studies of protective effects of hypoxia show different morphological changes in cornea epithelium during hibernation and after awakening. Administration of hypoxia during irradiation of hibernating animals was not effective while hypoxia admninistered in active animals at the moment of exposure showed positive results, also confirming the protective effects of hypoxia during the initial stages of radiation injury.
