We have investigated the influence of hipoxic gas mixture (HGM) (10% oxygen) on the morphometric indexes of respiratory section and on the state of connecting tissue of the lungs among the rats of different age. Morphometric and biochemical data that were recieved from 3-ìounts animals, which breathed HGM, can indicate the increase of general volume alveolar surfac`s area and intensification of fermentative destruction of new synthesized collogen, possible increase of the lungs blood filling, which facilitate the efficiency of gases interchange. Among 12-mounts rats was observed decrease in the thickness of interalveolar partitions and concentration of general oxyproline, that can point to the decline of relative collogen fibres content.
