Abstract
ABSTRACT In the present study the characteristics of lymph microcirculation are investigated. The lymph microcirculation wasstudied on small intestine mesentery during I\I'-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 meanvelocities of lymph flow in microvessels (parameters M1) were measured by the laser-speckle method. Simultaneously,diameters oflymph microvessels as well as parameters ofphasic contractions and valve functioning were registered.Keywords: lymph microvessels, stress, rat mesentery, speckle-interferometry, N- nitro- L-arginin Stress reaction of an organism has attracted attention due to its critical role in a broad spectrum of physiological processes and diseases including cancer and cardiovascular diseases. It is also known that stress is an important factor in
