Abstract
It is shown that as soon as the 1st day after transfer to high latitudes, the regenerative processes are suppressed in some cardiomyocytes, this manifesting itself in lytic changes of the sarcoplasm and organelles in the perinuclear zone. After flight in the middle latitudes morphological signs of disturbances in the processes of intracellular regeneration are observed only toward the end of the experiment. Intracellular spatial reorganization of cardiomyocytes for transfer to high latitudes and for flight in the middle latitudes has a stereotypic pattern and primarily manifests itself in an increase of the volume density of myofibrils and a decrease of this parameter for mitochondria.
