The problem of stress induced disorders of hemosta sis (ischemia, acute myocardial infarction, disseminated intravascular coagulation (DIC), thromboembolia, etc.) is important for clinics and basic research in medicine. These diseases cause disability and premature death of creative adults [17].Discoordination of systems of hemorheology, immu nity, hemostasis, and homeokinesis is a pathogenic mech anism of acute stress reaction [21]. Normal functions of visceral systems and the organism as a whole depend on invariability of intraorganismal media.Stress induced disorders are due to sharp changes in environmental conditions associated with industrial fac tors, urbanization, ecological disasters, and so called dis adaptation diseases.Pharmacological correction of stress induced disor ders causes not only positive effect but also allergic reac tion [21].Terahertz electromagnetic therapy (THG therapy) is a promising new method for treatment of various diseases [3]. In cardiology microwave therapy has been successful ly used for 20 years. THG therapy is used in surgery, trau matology, gynecology, dermatology, endocrinology, etc.The frequency range of THG therapy falls between 100 GHz and 10 THz or from 3 mm to 30 µm. From the bottom and top this range is limited by electronic transi tions in semiconductor structures (100 GHz) and maxi mum wavelength of transitions in laser structures, respec tively. This range falls between the EHF (100 300 GHz) and infrared wavelength ranges [4].It has been found that living organisms use radiation in this range for communication and control. Some living organisms are able to emit microwave radiation. The THG induced signals in living organisms simulate inter nal communication and control signals (information sig nals) in biological objects. This restores the radiation inherent in a healthy organism [12]. On the other hand, the THG frequency range includes emission and absorp tion spectra of most important cell metabolites (NO, O 2 , CO 2 , CO, OH , etc.) [14]. The biophysical effects of THG radiation can be used in biomedical engineering: THG therapy and THG diagnosis [3].Molecular emission and absorption spectra (MEAS) of nitric oxide (150, 176 150, 664 GHz) are of consider able interest in experimental research because NO is an important mediator of many physiological and patho physiological processes. NO is a unique second messen ger in most living cells. For example, NO mediates vasodilatation, bronchodilation, neurotransmission, platelet aggregation, immune reactions, muscular ten sion, memory, renal hemodynamics, glomerulofiltration, and some pathological processes [7,16,20]. It was shown that the MEAS of NO had a stress limiting effect [11].Noninvasive methods of NO secretion regulation are of considerable interest for basic research and medical practice. Low intensity THG radiation in MEAS of NO (150, 176 150, 664 GHz) provides a promising approach to this problem.There is experimental evidence that this radiation affects microcirculatory and rheological properties of blood a...
