[The psycho-physiological aspects of morbidity of cadets of military educational institutions].

The purpose of the study is to determine and to estimate the psycho-physiological factors affecting morbidity of cadets of military educational institutions. The study was carried put using sampling of 79 male cadets of the Academy of the Federal Penal Service of Russia. The cluster analysis was applied to indices of morbidity and psychological characteristics of cadets. The comparative inter-group evaluation of psychological indices and indices of heart rate variability was implemented. The obtained results specify differences in groups as a result of complex impact of various factors on morbidity indices.

[The organization of pre-clinical studies of bactericidal and wound healing effects of the impulse photoherapy device "Zarya"].

The purpose of the study is to determine therapeutic effectiveness of the pulsed high intensity optical irradiation device "Zarya" exemplified by treatment of model wounds in laboratory animals and to compare with traditional methods of wound treatment. The prototype of "Zarya" device was used whose operating principle was based on pulsed irradiation of affected areas with high intensity optical radiation in continuous spectrum generated by pulsed xenon lamp. The therapeutic effect of the "Zarya" device was compared with effectiveness of the certified medical ultraviolet irradiator based on low-pressure mercury lamp and also with known wound-healing and antibacterial medication Levomekol ointment. The mature male rats of Wistar line were used in the study. The animals were distributed to 4 groups: group 1 was irradiated by "Zarya" device, group 2 was irradiated by low-pressure mercury lamp, group 3 was treated with Levomekol ointment and group 4 was exposed to no exposure. The linear wound was modeled according to the standard method under ether anesthesia. The therapeutic procedures were applied daily during 7 days. The bactericidal effect was studied on the basis of smears from wound onto flora on the 2nd, 5th and 7th day. On the 8th day the animals were subjected to euthanasia. It was established that "Zarya" device application permits to reduce considerably both duration of therapeutic procedures and therapy course in general and also to achieve more pronounced bactericidal effect. The obtained data is supposed to be used for development of program of clinical trials.
