Abstract:A continuing relevance of the study is in researching of new non-drug methods of stress traumas correction. Stress is the main reason of different diseases and, first of all, of a cardiovascular system failure. The study aims the researching of the effect of electromagnetic waves of 150.176-150.664 GHz nitrogen oxide molecular and absorption spectrum occurrence. This is the most important natural regulator of endocellular interactions; it also influences the rheological blood indices in experimental stress-reaction of white malerats. The blood rheological properties research was organized with the help of the rotation viscosimeter with a free-floating cylinder "АКР-2" [trasliteration from Russian: "a ka er 2"]. The result of the experiments displayed that: 1) the exposure of electromagnetic waves of 150.176-150.664 GHz nitrogen oxide molecular and absorption spectrum occurrence is able to regenerate (depending on a time mode) acute stress-dependent blood viscosity defects and the functional erythrocytes activity -their deformability and aggregation; 2) a 5-minute exposure of electromagnetic waves of the same frequencies band does not have influence with the stress-damaged blood viscosity and functional erythrocytes activity; 15-minute and 30-minute modes of exposure of THz-band electromagnetic waves of 150.176-150.664 GHz nitrogen oxide are effective and totally regenerate stress-dependent blood viscosity defects and functional erythrocytes activity -their deformability and aggregation.Keywords: hemorheology, electromagnetic exposure, THz-band, nitrogen oxide, erythrocytes, viscosity.
IntroductionStress situations (physical and psychological overstrains, emotional overloads) are the most important causative factors leading to a cardiovascular system pathology. It is commonly known that all of these factors are stress-factors; they cause general adaptation syndrome or the stress-reaction. This is accompanying by the amount of the complex of syndromeshypertensive disease, hypercoagulability, hyperlipidaemia, depression and agitated state, cardiovascular system failure, immunodeficiency [1]. Nitrogen oxide is the prime natural regulator of endocellular interactions [2][3][4][5]. It is a neuromediator, potent hemostasis factor, antiaggregant, endogenic vasodepressor [3,[6][7][8], and it fulfils many important functions in an organism. It is indicated that nitrogen oxide has a stress-limiting effect [9].Nowadays much attention is given to the point of the interaction of biological objects with GHz nitrogen oxide molecular and absorption spectrum occurrence [10][11][12].THz-therapy can be a new perspective non-drug method in treatment of many diseases [13]. The THz-band (100GHz -10THz) is interesting by having molecular and absorption spectrum occurrence of the major cell metabolites (NO, O2, CO2, CO, OHetc.) [13].
