[Smooth muscle cells of blood vessels in response to vibration]

In smooth muscle cells of the rat femoral arteries, when the animals have been subjected to a prolonged general vibration (100 Hz, amplitude 0.5 mm), size of their nuclei increases. The nuclei of myocytes in the posterior vena cava in the experimental animals are also larger than in the intact ones. Increase of the volumes of the smooth muscle cells in the posterior vena cava is not connected with the increase of the level of their ploidity. In the control animals accumulations of glycogene are revealed in the smooth muscle cells situating along the course of the internal elastic membrane of the femoral arteries. Single glycogene granules are found in other areas of the t. media. The type of glycogene distribution in the muscle layer of the femoral arteries remains the same in the rats after vibration, however, its general content is essentially decreasing.
