    Abstract:
    The method of lymphorentgenography was used in order to study alterations in the lymph vessels of pelvic extremities of rabbits at different terms (from 1 week up to 6 months) after exposure to gravitation stresses of different directions, value and duration. After exposure to stresses of cranio-caudal direction the amount of vessels increased. They had weel pronounced sinuosity and clearly protruding valves. The diameter of the vessels was more than normal and was equal to 0,3-0,8 mm. Popliteal lymph nodes were also increased up to 12,6-6,7 mm. Within 6 months after stresses these changes retained. Stresses of caudal-cranial direction during all periods of observation (from 1 week up to 6 months) caused dilatation of vessels (0,3-0,6 mm), their sinuosity and enlargement of popliteal lymph nodes up to 10,5-6,2 mm. All these changes returned to normality within 6 months. Thus, most pronounced and resistant morphological changes of the lymphatic bed were caused by greatest endurable stresses of cranio-caudal direction.
