Paper Abstract

In the present study the characteristics of lymph microcirculation are investigated. The lymph microcirculation was studied on small intestine mesentery during NG=nitro=L-arginine (L-NNA) application on intact microvessels and after stress. The direct measurement of lymph flow velocity (parameter V) in individual microvessels was based on the technique of light intravital videomicroscopy. The first spectral moments of Doppler signal characterizing the mean velocities of lymph flow in microvessels (parameters M1) were measured by the laser- speckle method. Simultaneously, diameters of lymph microvessels as well as parameters of phasic contractions and valve functioning were registered.
