The article describes the new method of assessment of microcirculatory blood perfusion and introduction of this method into the study of intranasal drugs effects on mucosal blood flow in the nasal cavity. The research work presents some different groups of drugs — decongestants, physical solutions for irrigation therapy and local corticosteroids. It has been revealed that intranasal decongestants have a significant effect on the intranasal blood flow, but their intake affects the mucosal membrane of the nasal cavity. Other drugs have not shown such negative effects and have not caused tachyphylaxis. Therefore these medicines may be recommended for more common use in ENT-practice.

Aims. The research aimed the studying and optimizing of the possibility of measuring microcirculatory of blood fow in human skin by laser Doppler fowmetry (LDF) against the various topographic features of the peripheral blood supply of tissues. Materials and methods. 20 people of the age from 20 to 56 years without signs of skin lesions were examined by the LDF device. The LDF device has two radiation sources in the red light at a wavelength range of 650±30 nm and the near — infrared at a wavelength of 805±50 nm. The radiation was carried out with four receiving fbers arranged at distances of 1, 2, 3 and 4 mm from the illuminating fber. The state of microvasculature was studied at four points of skin — in the middle of the forehead, in the center of the right cheek and the symmetric point on the left cheek and chin area. We calculated the average values of microcirculation, its standard deviation and coeffcient of variation. Conclusions. By varying the distance from the illuminating fber to the receiving fber and the wavelength of incident light the values of the microcirculation in the different areas of healthy skin were estimated by laser Doppler fowmetry method (LDF). Tissue probes, the spatial localization of the LDF signal in the tissues and the effective depth of detection have been estimated by Monte Carlo method. It has been found out during the study that the LDF signal changes are directly related to the structural features of the structure of the microvasculature, the depth and density of functioning capillaries. The given method can be used to diagnose the state of biological object in the normal and pathological conditions, as well as evaluating the effectiveness of the treatment of various dermatoses.

The research goal is to estimate a condition of microcirculation in a bladder neck in patients with benign prostatic hyperplasia (BPH) and its value in pathogenesis of bladder neck sclerosis. Materials and methods: Work basis included the analysis of treatment results of 1171 patients with BPH who carried complex examination, operative treatment and further supervision. The basic group was made up of 182 patients with BPH who developed bladder neck sclerosis in the postoperative period. The control group consisted of 200patients with BPH who did not develop the described pathology. clinico-anamnestic, laboratory methods and instrumental studies were used. Results: Disturbance of microcirculation in a bladder neck was considered to be a pathogenetic factor of sclerosis development as one of seri¬ous complications of operative treatment in case of BPH. The presence of microcirculatory disorders was confirmed by histological analysis. Inflammation in the bladder neck should be considered as an aggravating factor. Conclusion: The presence of microcirculatory disorders in the bladder neck in patients with BPH requires preoperative corrective therapy for prevention of sclerosis

Results of treatment of 135 victims with damage of a pancreas and results of experimental researches lead on 127 white rats are analysed. It is established, that expansion of volume of operation on damaged iron does not conduct to
improvement of results of treatment. Phase changes of average perfusion blood in a pancreas are revealed at development of an experimental posttraumatic pancreatitis. Development destruction in iron coincided on time with a phase re-perfusion. Local hypothermya pancreas reduced rate re-perfusion and reduced a degree destruction its fabrics. By results of research the technique intraoperation preventive maintenance of complications of damages of a pancreas is developed
