摘要

Abstract: The effects of distant light diode irradiation with various spectrums of the trunk vessels on reactivity of microvessels in the small intestine mesentery treated with threshold doses of norepinephrine (NoE) are compared. The character of changes in reactivity of microvessels to NoE was found to depend on the wave length and irradiation dose. Ultraviolet irradiation (470 nm, 0.03 J/sm$+2$/) was noticed to increase reactivity of the vessels to NoE (vasoconstriction increase). In green light irradiation (540 nm, 0.3 J/sm$+2$/ sm$+2$/) no changes in reactivity were observed. Red light irradiation (670 nm, 2.0 J/sm$+2$/), infrared particular (980 nm, 1.0 J/sm$+2$/), lowered reactivity to NoE. Thus, noninvasive light-diode irradiation of the blood results in different systemic changes of endothelial dependent reactivity of microcirculation due to specify of photochemical processes involved. !3
