title: [Effect of vibration on the functioning of the lymphatic system in the small intestine in rat].
abstract: The production rate and flow of the lymph in mesenteric lymph vessels under normal conditions and after horizontal vibration of 5 Hz frequency and 20 mm amplitude were measured by means of intravital, intravenous injection of trypan blue water solution. The investigations were carried out on 66 Wistar rats of both sexes. It was found, that 3 and 7-hour vibration and everyday 7-hour vibration applied during a week result in the acceleration of lymph flow, whereas 3- and 4-week vibrations result in reduction of production and flow of the lymph. In all cases the lymph flow speed becomes normal after one day break. The results obtained show that low frequency vibration causes reversible functional changes in small intestine lymphatic system. These changes more probably result from hemodynamic disturbances. The applied vibration parameters did not cause any perceptible morphological changes in the lymphatic system.
