摘要：

The experimental investigations of rat mesenteric lymph microvessels by using vital biomicroscopy with videotape system recorder, still pictures of frames and image processing system have been carried out. It is established that intravenous administration of sodium nitroprusside induces differently directed changes of vascular diameter. The majority of lymph vessels are dilated. Degrees of dilation in central and valve regions of lymphangions are different. He-Ne laser irradiation of mesentery at the increase of nitric oxide (NO) synthesis after sodium nitroprusside injection stimulates phasic contractions in part of the vessels. Used dose of laser irradiation doesn't influence on intact microvessels. Sodium nitroprusside increases sensitivity of lymph microvessels to He-Ne laser irradiation.
