The article contains the research results of the effect of cadmium chloride on the indexes of enzyme and nonenzyme systems of  antioxidant defense system in young cattle, such as the activity of catalase, superoxide dismutase, glutathione peroxidase, glutathione levels of vitamins A and E. It is established that feeding calves at a dose of toxicant 0.04 mg / kg activity of catalase, superoxide dismutase, glutathione peroxidase, glutathione levels of vitamins A and E in the blood of experimental animals decreased throughout the experiment. The lowest indicators of antioxidant in the blood of young cattle is set on the twenty -fourth day of the experiment, which is associated with increased activation of lipid peroxidation and the balance between antioxidant system and lipid peroxidation intensity. Given the cadmium load of young cattle it is used a new integrated drug with antioxidant action «Metisevit», which includes metifen, sodium selenite and vitamin E wich is founded as stimulating effects on the activity of antioxidant protection. In particular,it is established probable increase in activity of catalase, superoxide dismutase, glutathione peroxidase, glutathione levels, vitamin A and vitamin E in the blood of young cattle, which has performed cadmium stress. These changes occur through comprehensive action components of the drug «Metisevit» that leads to the normalization of metabolic processes and free radical in the body of the bull. The results of the research indicate antioxidant drug «Metisevit» in the application of its young cattle and the validity of his administration to improve the body's antioxidant status of chronic cadmium toxicosis.

The level of primary and secondary lipid per oxidation products were investigated: diene conjugates and malondialdehyde in conditions of nitrate loading. It was established that at bulls feeding with sodium nitrite at a dose of 0.2 hNO3ˉ/kg of body weight, the level of diene conjugates and malondialdehyde in their was increased during the entire the experiment. On the 30thday of the experiment the level of diene conjugates in blood of bull, which were conducted with nitrate load was 7.44 ± 0.15 mmol/l, and the level of malondialdehyde – 0.305 ± 0.014 mmol/l.Under conditions of nitrate load , young cattle was used a new integrated drug «Metisevit», which consists of sodium selenite, vitamin E and metifen. It was found the stimulating effect of metifen and metisevit on antioxidant system of the body of young cattle. Depressing effect of metifen and metisevit on the processes and lipid per oxidation in the blood of bulls under conditions of chronic nitrate–nitrite toxicity. Metifen and metisevit interact with radicals of fatty acids and delay the development of a chain reaction of oxidative stress, reduce the oxidation of phospholipids and form a biologically inactive compound with products of per oxidation of fats. Obtained results of the research indicate antioxidant drugs «Metisevit» and «Metifen» in the application of their young cattle.The mentioned changes are occurring through the comprehensive action of the drug components «Medisvit», that leads to the normalization of metabolic processes and free radical in the body of bulls. Obtained results of the research indicate the antioxidant action of the drugs «Metisevit» and «Metifen» in the application of their young cattle and the reasonableness of their administration to improve the antioxidant status of the organism according to nitrate loading.

An important element in solving problems relating to the preservation of young cattle livestock and production increase of livestock products is a timely diagnosis, prevention and treatment of diseases of non-communicable etiology, among which one of the most common is bronchopneumonia. Therefore, the development of effective methods of treatment and prevention of this pathology is an urgent problem of veterinary medicine. Despite a large number of scientific researches, many issues of etiology, pathogenesis, treatment and prevention of this disease remain insufficiently studied, especially the state of the natural resistance of calves suffering from catarrhal bronchopneumonia, which is the basis for choosing a method of treatment and prevention of this disease. The disease leads to calves deep, sometimes irreversible disturbances of bronchopulmonary system functions. Lung function is one of the first to be disrupted, playing an important role in the protective immunological reactions of the body, through which there is an increase in virulence of microorganisms, which leads to the general intoxication and severe bronchopneumonia. The situation on non-specific bronchopneumonia of calves in the Lower Volga region is tense, but it is to the same extent as in other regions having problems with this pathology. It is obvious that the susceptibility of calves to respiratory diseases is formed under the influence of antenatal influences and is manifested in the presence of adverse environmental factors leading to depletion of reserves adaptation in the first months of animal life.  The obtained set of regional characteristics of bronchopneumonia of non-infectious etiology allows to consider this pathology as an indicator of the ecological unwell-being of big cattle herds in the Lower Volga region.

Total Effective Dose

Abstract The purpose of the research is to develop an integrated technique for determining the effective dose (E) of external and internal exposure by different sources of ionizing radiation. The proposing technique for determining the total effective dose is based on three methods of calculation. The first one is multiplying the value of the individual dose equivalent $H_{p}(10)$ by the factor of 0.642 to account for radiation shielding by various organs and tissues and its backscattering. The second method is multiplying $H_{p}(10)$ by the conversion factor of air kerma in free air in a plate phantom, depending on the photon energy. The third method is multiplying $H_{p}(10)$ by the sum of the radiosensitivity coefficients of various organs and tissues. As a result of research, a complex method was developed for determining the total effective dose, composed of doses of cosmic radiation, external gamma-, beta- and neutron radiation, internal exposure from radionuclides, including CDP of radon and thoron, entering the body through the organs of digestion and respiration. The proposed technique for determining the total effective dose allows one to take into account the comprehensive effect of ionizing radiation sources on a person and to obtain a more accurate measure of radiation risk than the existing methods provide.

We studied seasonal variability in photodegradation of dissolved organic carbon (DOC) resulting from artificial ultraviolet-A (UV-A) and UV-B irradiation. Water samples were taken approximately monthly from the surface layers of two oligotrophic lakes with contrasting humic content, situated in southern Sweden. Lake water was filter-sterilized (0.2 μm) and exposed to artificial UV radiation in quartz tubes. Potential DOC photodegradation, measured as a photoproduction of dissolved inorganic carbon (DIC) and oxalic, malonic, formic, and acetic acid in irradiated samples, was observed throughout the sampling period. In addition, exposure to UV radiation resulted in a decrease in DOC, absorbance, and humic substance fluorescence. The photoproduction of DIC and the low molecular weight (LMW) organic acids varied seasonally, being generally higher in winter and spring (December-May), while DOC appeared to become less photoreactive after the extensive exposure to solar radiation during summer. Production rates of both DIC and LMW organic acids were approximately eight times higher in the humic lake despite that the DOC concentration was only two times higher than in the clearwater lake. This is most probably due to the high input of allochthonous DOC and the resulting higher absorbance to DOC ratio in the humic system. Furthermore, the longer hydraulic residence time in the clearwater system could have resulted in an accumulation of residual DOC, recalcitrant to further photodegradation.

One of the most effective ways of removing HM salts that have entered the digestive tract of fattened animals is the technological method of including adsorbent preparations in their diets, which, binding various toxins, excrete them from the body. The study purpose is to develop a method to increase the meat productivity and quality of meat of young cattle for fattening in a technogenic zone by inclusion of ToxySorb adsorbent in their diets with a high content of heavy metal salts in the amount of 1.25 kg/t of compound feed and lecithin in the amount of 10 g/100 kg of live weight. According to study results, it was shown that when these drugs were fed together in the indicated quantities, it contributed to better detoxification of xenobiotics. The calf bulls of experimental group 3 had the best slaughter indicators, as well as the best consumer, sanitary and hygienic properties of meat products.
