For studying the mechanism of a positive effect of teraherts waves at frequencies of a molecular spectrum of radiation and absorption nitric oxide of 150,176-150,664 GHz on linear speed of a blood-groove of the male rats subjected sharp immobilization to stress, were investigated parameters of hemodynimic in the main vessels: a belly aorta, femoral and sleepy arteries before carrying out an irradiation with 30 minutes on a background of injection of endothelial NO shynthase inhibitor L-Name. Absence of normalizing effect on parameters of bloodhemodynimic during 30 minute irradiation with teraherte waves at frequencies of a molecular spectrum of radiation and absorption of nitric oxide of 150,176-150,664 GHz in a belly aorta and a femoral artery of the animals at the condition of sharp immobilization on a background of endothelial NO shyntase action L-Name was shown. It testifies to a role of endogenous NO and endotelial NO shyntase in mechanisms of potentiation of positive correction of at irradiation on frequencies MSRA nitric oxide of 150,176-150,664 GHz on the broken parameters of linear speed of a blood-groove. 30 minute irradiation with therahtrts waves at frequencies of nitric oxide a molecular spectrum of radiation and absorption of 150,176-150,664 GHz in a carotid of the animals were in a condition of sharp immobilizanion on a background of action of endotelial NO shyntase L-Name, does not cause any changes neither in comparison with control group of animals, nor with group of the animals who were taking place in a condition of sharp immobilization of stress. Apparently, it specifies centralization of a blood-groove during action of stress agent therefore there is a maintenance of blood supply of the vital body of a brain at a constant level.
