| Abstract: | A comparative study was made of changes in radiosensitivity of mice and rats given hypoxic mixtures (GHM) containing 6 to 15% of oxygen. The radioprotective effect of the GHM was more pronounced in mice than rats. The dependence of the radioprotective effect of the GHM on the oxygen content was well approximated by the equations: (Formula: see text). In experiments on rats, the oxygen content of 13.8% was shown to be a threshold the exceeding of which removed the modifying effect of the GHM. |
