[Morphology of the wall of some main arteries normally and in limited motor activity].
Effects of different periods of hypokinesia upon the structure of the main arteries wall and the microcirculatory bed of the aorta adventitia were studied in rabbits by histological methods. It was shown that hypokinesia lasting more than 4 weeks resulted in the atrophy of the medical sheath and dystrophy of the elastic framework in the wall of main arteries. In the microcirculatory bed of the aorta adventitia there occurred blood stagnation, the integrity of the microvessels wall (mainly capillaries, postcapillaries and venules) was broken. The degree of the above morphological changes depends on duration of hypokinesia.
