Bone mineral density of female rats in the process of adaptation to simulated durative intermittent hypobaric hypoxia

The estimation of femoral mineral density by Х-ray computer microtomography and indicators of adaptive processes in female rats in the simulation of chronic intermittent hypobaric hypoxia is presented. An increase in heart and adrenal mass, an increase in the number of red blood cells and hemoglobin were markers of compensatory processes. The obtained results indicate that long-term intermittent exposure to hypobaric hypoxia, both in conditions of severe adaptation, and with a gradual build-up of the stress factor, can lead to osteoporotic changes in the bone tissue.
