Abstract

The measuring method of microcirculatory parameters using strongly focused Gaussain beam (SFGB) diffraction phenomenon has been proposed in this paper. The method has been applied for the investigation of lymph flow characteristics in microvessels in vivo. Intensity, fluctuation spectra of a scattered field which are the result of laser beam diffraction in lymph vessels have been presented in the paper. It has been shown that the alterations of spectra shape depend on peculiarities of lymph motion in microvessels. Physical parameters of determination both of temporal changes of mean velocity and of spatial-temporal velocity distribution in lymph microvessels have been proposed. An action of lymphotropic drug on the lymph flow parameters have been studied.
