The purpose of the work was to study the possibility of using local clay as a 137Cs sorbent when including it in the diet of lactating cows. The research was conducted in 2020 in the Zlynkovsky district of the Bryansk region contaminated with radioactive substances as a result of the disaster at the Chernobyl Atomic Electric Power Station. In the experiments, animals selected according to the principle of analogues were used, which were fed with clay, in accordance with the experiment scheme, previously mixed it with concentrated feeds. The experiments were carried out in the winter-stall and summer-pasture periods. During the research, the daily milk yield was considered and milk samples were taken. Then the 137Cs and milk fat content was determined in them. The obtained results were subjected to statistical processing. As a result, it was found that clay included in the cow diet reduces radionuclide content in milk. In the first experiment carried out during the winter-stall period, the inclusion of clay in the diet in the amount of 200, 400, and 600 g/day/head reduced the 137Cs content in milk of the experimental groups by 30% (P>0.05), 50% (P<0.05), and 80% (P<0.05) accordingly. In the second experiment, performed during the summer-pasture period, clay was added to the main diet in the amount of 300 and 600 g/head/day. As a result, the content of 137Cs in milk decreased by 42 and 79%, respectively, compared with the control group. At the same time, there is a positive trend in clay effect on dairy productivity. The inclusion of clay in the animal diet in the amount of 300 and 600 g increased the daily yield by 4 and 6%, respectively.

Krasnoyarsk state medical university, russia Физический статус женщин пожилого возраста изучен с помощью антропометрии и биоимпедансного анализа, индексная оценка включала определение индекса массы тела и расчет коэффициента скорости старения по методу А. Г. Горелкина и Б. Б. Пинхасова (2010). Определение индекса массы тела позволило установить преобладание в исследуемой выборке женщин с ожирением (50,89 %) и избыточной массой тела (31,36 %). Обнаружены достоверные различия между показателями физического статуса, а также неравномерность темпов старения женщин пожилого возраста с различным индексом массы тела. Ключевые слова: физический статус, антропометрия, компонентный состав тела, индекс массы тела, скорость старения, женщины пожилого возраста The physical state of elderly women is studied using body anthropometry and bioimpedance analysis. Index evaluation included determination of body mass index and the calculation of the aging rate by method of A. G. Gorelkin and B. B. Pinkhasov (2010). Determination of the body mass index has allowed to establish the prevalence of obese women (50.89 %) and overweight women (31.36 %) in the studied sample. Significant differences between the physical state indices are revealed, as well as the uneven aging rate of elderly women with different body mass index.

The study includes anthropometry of 172 young male, obtained data on the length and body mass, measured the transverse diameters of the shoulders and pelvis, various body types was identified by the J.M. Tanner sexual dimorphism index (andromorphic, mesomorphic, gynecomorphic). The chemiluminescent and bioluminescent study of saliva and blood was conducted in the examined young male. We studied the indicators of the antioxidant defense system under the influence of stress. The antioxidant status of saliva was determined using the H2O2-luminol-dependent chemiluminescence method. Data on the activity of NAD (P) -dependent dehydrogenases in blood lymphocytes was obtained from a bioluminescent method of research. Young male of andromorphic body type had large overall and transverse body sizes. Indicators of antioxidant protection of saliva and blood in men of adolescence, the body type of the sexual dimorphism index J.M. Tanner was different. The persons of the andromorphic body type differed in terms of chemiluminescence in comparison with the young male of gynecomorphic body type. The results of bioluminescent blood tests suggest a violation of the catabolic and anabolic processes of carbohydrate and fat metabolism in young men of mesomorphic and gynecomorphic body types. Indicators of the system of antioxidant protection of saliva and blood reflect the sexual characteristics of the body of young male and can be used as additional criteria for diagnosing sex inversion and assessing the risk of developing socially attributed diseases.
