Hair ultimate composition was studied in 123 residents of the northern region (Khanty-Mansiysk Autonomus Gegion-Yugra). 45 drivers and workers of petrol-filling stations (AZS) made up the 1st group (average age 40.8 ± 14.2 years) and 78 employees - 2nd group (average age 38.7 ± 15.8 years). Content of Ca, Cd, Cu, Fe, Pb, Se and Zn was identified in the hair of northerners by AES-ISP, MS-ISP methods. In surveyed persons of the 1st group significantly lower concentrations of toxic chemicals (Ca - p = 0,019) and antioxidant (Se p < 0,001, Cu - p = 0,010, Zn - p = 0,046) and higher content of toxic chemicals (Cd, Pb - p < 0,001) were revealed in comparison with the surveyed persons of the 2nd group. Lead intoxication indicators (Ca/Pb - 100) are 6.2 times and cadmium (Zn/Cd - 500) 2.6 times and indicators deviance of antioxidant protection system (Fe/Cu > 0,9) occurred 2,2 times oftener in the hair of surveyed persons of the 1st group. Arranging of indicators characterizing functioning of antioxidant protection system is important for recommendations development on prevention of specific processes formation caused by peroxidation activation that in spite of peroxidation syndrome development gives rise to environmental pathology, complication of general and work-related diseases state in risk group contingents.

It is known that the psycho-emotional and mental stress can lead to the disruption of adaptation process, which is accompanied by severe metabolic changes in the body. In this regard, the aim of this work was to study the effect of mental and emotional stressor (exam) on free radical processes and morphological picture of the salivary fluid in students from different ethnic groups. The study involved 129 students of the 1 course of which 70 healthy volunteers were included in the final study group on the basis of personal data. After attrition students were divided into 3 groups according to their ethnicity - Russians, Africans and Indians. Salivary fluid collection was done before and after the exam, then collected biomaterial was analyzed by induced chemiluminescence and wedge dehydration methods. For volunteers observed within each ethnic group have been installed 3 categories for free radical oxidation (FRO) level: low (0-0,35), medium (0.35-0.5) and the high (0,5<). Students with initially low and middle FRO level of salivary fluid stress caused an increase in the intensity of the chemiluminescence (CL) emission. For students with high luminescence was established ethnic relationship: Russian demonstrated increase in FRO level, Africans and Indians showed its decline. The ratio of occurrence of salivary fluid facies was dependent on the ethnic group - in Russians has not changed under the influence of a stressor, in Africans and Indians was reversed. Correlation between CL intensity and the crystal parameters of central zone of salivary fluid facies was also revealed. O the basis on these data we can assume a weak adaptive capacity to the conditions of emotional stress in Russian and Indian students and stimulation of adaptive capacity in African students.

This work presents the results of a multiply structural and dynamic investigation of seasonal changes in psychophysiological indices of the athletes and skiers in the European North of Russia. The study of the central nervous system functional status and regulation of the autonomic nervous system during the annual training cycle was made to reveal psychophysiological characteristics of young athletes. On the basis of obtained data, the influence on the level of activation of the nervous system characteristic features of activity in which the athlete was engaged in was stated. Special aspects of seasonal dynamics indicators of the operator's working capacity in the studied groups were defined. On the basis of data analysis of variation cardiointervalography relationship of an organism regulatory systems tension with peculiarities of athletic training was defined. As a result, it was found that the skier's organism undergoing aerobic activities during training was less affected by negative environmental factors, compared to the athlete's organism, performing a physical activity with a predominance of anaerobic activity that requires total efficiency of the organism and greater involvement of regulatory systems. So, the athletes are more exposed to risk of exhaustion of physiological reserves, and use of psychophysiological testing for them can serve as means of preventive control of overpressure and overtraining syndrome.

The article presents literature review on study history of ischemia of great gut. The study of this problem began in 1834 when Despre published the first message on bowel infarction with preceding chronic ischemia of intestines. In recent years interest to great gut ischemic defeats has increased. It is not surprising taking into account extreme prevalence of vascular diseases. There are known reliable pathomorphological data on colon mucosa change into acute ischemic colitis, nevertheless there is hardly any information in literature on morphofunktional change of a mucous membrane with early stage of chronic regional misperfusion. The research is necessary for timely diagnostics of a great gut chronic ischemia and prediction of colic anastamotic dehiscence and great gut gangrene in various clinical settings. Despite of various ways of great gut chronic ischemia diagnostics, complexity of this pathology definition with early stage is obvious and requires search for new methods of disease verification. There are a lot of facts describing pathogenesis of great gut vascular abnormalities with criteria of their recognition. It is necessary to know history of scientific research, mistakes, achievements, problems met by the previous generations of experts dealing with this problem to move on.

Every year from 296 812 to 681 056 incidents of invasion diseases are registered in Kyrgyz Republic. It means that each 8th inhabitant has parasitic diseases and each 6th child aged up to 14 suffer from helminthes. In the years 2012-2014 the study on fauna determination of persons' endoparasite among the population of Kara-Suy region was made together with parasitological laboratory of health inspection service. The work was devoted to echinococcus research. Echinococcus was found in 7,9 % unemployed people, 6,5 % housewives, 14,3 % in pensioners among Kara-Suy region population. Infection rate among surveyed was 0,6 %. During 2012-2014 decrease tendency of echinococcus disease was observed. However this tendency is not stable as the rate of infection is still high. It means that more and more healthy people will be involved in echinococcus epidemic process if the situation will not be changed fundamentally. Human echinococcus incidence rate is coherent with animals' echinococcus infection rate. During 2012-2014 about 997 domestic animals, infected by echinococcus were resisted in the region. More than two tons of animal organs infected by echinococcus were taken out at the slaughter. There exists probability of feeding dogs with the infected organs which causes environment pollution with echinococcus in Kara-Suy region. According to the statistics of Osh Environmental Protection Department all the slaughter units belong to ecological risk group due to environmental contamination with tapeworm echinococcus eggs.
