[Morphofunctional characteristics of murine kidneys in single and fractionated irradiation in air and hypoxia (8% of O2)].

The protective effect of hypoxic gas mixture containing 8% of oxygen (HGM-8) has been studied in long terms after local single and fractional X-ray irradiation of the kidney in mice. Some criteria of injury shown that hypoxia protects the kidneys against irradiation, changes in irradiation dose constituting 1.25-1.33. When passing from single irradiation to five-fold daily one, the protective effect of hypoxia does not fall significantly.
