title: [Prolonged hypokinesia and its influence on the tissues and vessels of the extremities in experiments].
abstract: The work describes the results of complex investigation of the state of the supporting-motor apparatus of extremities of dogs subjected to six-month-long restriction of motor activity and the following reparation during a month. Intravital rentgenological, anatomical, histochemical and electron microscopic methods were used. It was shown that continuous hypokinesia resulted in substantial alterations of the vascular bed in the macro-micro-ultrastructural level, disturbance of metabolism, focal reconstruction of tissues of the extremities by the type of natural death of ultrastructural elements without a following reparation. A one-month term appeared to be insufficient for reparation of structural disorders. Special attention was given to reactions of the vascular system. Signs of blood transport via extracapillary pathways from the arterial bed into the venous bed were noted.
