Abstract

The lymph flow velocity in microvessels of rat mesentery was investigated by using biomicroscopic manual frame-by-frame technique with image processing system and speckle- interferometrical method. Lymph flow was observed in the majority of lymphatics. Lymph flow was registered in microvessels with phasic contractions and functioning valves. The lymphocytes motion in flow was measured. It was established that mean lymph flow velocity increased in vessels with phasic contractions and moderate concentration of lymphocytes in flow. The application of speckle- interferometry allowed us to estimate lymph flow on the whole with all stops, the increases and decreases of flow velocity. The parameters both of changes of a mean velocity and of spatial-temporal velocity distribution in lymph flow were calculated. Temporal changes of the parameter V showed a shuttle-type character of lymph flow velocity.
