Abstract
During adaptation of rats to high-altitude hypoxia evidence of stimulation of both formative and lytic processes was observed, and either one process or the other was predominant in different cells. The ratios between volumes of mitochondria and myofibrils were substantially unchanged. The relative volume of the microcirculation was increased on account of dilatation of the small vessels with no increase in their number.
