We investigated the influence of a dosed condition regime of breathing the artificial gaz mixture with a lower P0   at the normal

atmospheric pressure on the biochemical indices of bones after axial unloading of rear extremities of rats of different age. The gaz mixture with a lower oxygen content supplied in the faltering regime activizes the rat bone tissue remodeling and hinders the destructive processes to a greater extent in young animals compared to adult ones.
