Abstract. Modern conditions of animal husbandry and poultry farming dictate a continuous search for effective means that increase the natural resistance of the organism of farm animals and poultry. The purpose of the study. In this regard, an experimental study was conducted on laboratory animals using a mineral adaptogen of domestic production in order to determine its effectiveness in conditions of artificially induced immunosuppression. The objectives of the study were to determine the immunobiochemical status, subcellular and intra-organ changes in the organs of the immune system at all levels. Research methods. Experimental studies were carried out using generally accepted zootechnical, pathomorphological, histological, immunobiochemical and statistical research methods. Results. Immunobiochemical changes in the body of experimental animals are described. Microscopic changes at the level of tissues and cells in the organs of the immune system at all levels are described. Changes in the organs of the immune system during immunosuppression and against the background of feeding mineral adaptogen are described. Morphological examination of the immune system organs in experimental animals revealed prolonged immunosuppressive changes for 14 days. At the same time, after induced immunosuppression, significant structural changes remain in the central and peripheral organs of the immune system in the form of lymphoid tissue atrophy (in the thymus, both in the organ of central immunogenesis and in the organs of the peripheral immune system – the spleen and lymph nodes and intra-organ lymph formations). During histological studies, the structure of cells and tissues, when using a mineral adaptogen, was more morphologically mature and was in a functionally active state, and dystrophic and necrotic processes were observed in the control group. The conducted studies convincingly prove the effect of mineral adaptogen on increasing natural resistance and its immunoprotective properties. Scientific novelty. For the first time in experimental conditions, a simultaneous assessment of the immunobiochemical parameters of the blood of laboratory animals and a microscopic examination of the organs of the immune system at all levels with morphometric analysis of the data obtained were given. As a result of the conducted studies, the immuno- and organoprotective effect of feeding the mineral adaptogen was proved and the immunomodulatory effect was morphometrically confirmed.

The aim of the study. To investigate in experimental conditions the effect of bismuth citrate on the immune system of laboratory animals. Material and methods. One-time sensitization of tadpoles (subcutaneously into the ear) was performed according to the method of O.G. Alekseeva, A.I. Petkevich. The degree of sensitization was established after skin tests. Determined the leucocyte blood formula, T and B lymphocytes in peripheral blood by the rosette method, immunoglobulins of class A, M, G in serum - by the method of radial immunodiffusion of globulines in agar Difco, circulating and extracellular complexes detection of the response of blood cells to the allergen "in vitro" - by the reaction of specific leukocyte lysis. Results. Bismuth citrate causes impaired immunological homeostasis in experimental animals. Indicators of nonspecific cellular component of the immune system have changed significantly, characterizing immunocomplex pathology. A decrease in the T-helper subpopulation was observed, indicating a significant immunomodulatory ability of bismuth citrate. At the same time, there was a significant increase in cells capable of rosette formation, which suggests that bismuth citrate is capable of provoking sensitization of the body. In the humoral immunity link, significant differences in the content of circulating immune complexes in sensitized and control animals were observed. Immunoglobulin levels were unchanged relative to control. The analysis of the sensitizing effect indicates that the most probable result of sensitization of the organism in this mode of receipt of bismuth citrate is the formation of type III hypersensitivity. Conclusions. Bismuth citrate under experimental conditions causes changes in the immune system of experimental animals, which are characteristic of the allergenic response of the organism to the complement-dependent type.

The article describes the results of experimental studies aimed at investigating toxic effects of methyl tertbutyl ether [MTBE] and nitrobenzene [NB] according to the criteria of changes in the immune system status of laboratory animals in conditions of cold stress and in conditions of temperature optimum. The research was carried out in the conditions of a subacute experiment (during one month of experiment) on laboratory animals (adult WAG male rats). The NB or MTBE were injected into the stomach at a dosage 1/10 LD50 (70 mg/kg of NB and 500 mg/kg MTBE) thirty times, the experimental animals were kept in two different temperature conditions during four hours five times per week. The animals were divided into 4 groups, six animals in each group. The animals of the first group were subjected to NB or MTBE at an air temperature of 252C (normal ambient temperature). The animals of the second group served as a control group for the first one. The animals of the third group were subjected to NB or MTBE in combination with the lowered air temperature of 4±2℃. The animals of the fourth group were only subjected to the effect of the reduced temperature of 4±20℃, that is, they were a control group for the ones of the third group. The analysis of the results of the experimental data about the features of the immunotoxic action of NB and MTBE under conditions of cold stress indicates the tension of the immune system of the laboratory animals, which is manifested by progressive lymphopenia and a decrease in the phagocytic activity of neutrophils in absorption of foreign agents, especially in the end-period. The immunotoxic effect of NB and MTBE under conditions of temperature optimum indicates a temporary immune system tension, namely leukocytosis and leukopenia at the stage only after 5 and 15 priming. At the end of the priming period, shifts in the immune system's performance under the effect of NB and MTBE under temperature optimum conditions were not observed, which may indicate a positive adaptability of laboratory animals to the action of chemical factors (NB and MTBE) under such temperature conditions. The combined effect of NB and MTBE on the body at the level of their effective concentrations and low temperature causes a detrimental effect on the adaptability of the body. Thus, these chemical compounds at the stage of physiological adaptation, that is before the formation of the pathological process, complicate the formation of specific and nonspecific reactions responsible for the adaptation of the organism to the effect of another factor in the production or environment – a low air temperature. The latter, in turn, creates an additional load on biochemical detoxification systems, leads to their imbalance and changes in the rate of biotransformation of the chemical agent and the speed of development of the toxic process.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

AbstractSerum immunoglobulin (IgG, IgA and IgM) levels were determined in patients with chronic tonsillitis before and one month after tonsillectomy. The preoperative levels of serum IgG, IgA and IgM were significantly higher when compared with the controls. The increase may be due to repeated antigenic stimulation. The post-operative levels for the three immunoglobulins were decreased; however, a significant reduction was observed for IgG only where the mean value was comparable with the control group. The data confirm that tonsillectomy does not disturb the humoral immune system of the body.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Fungal contamination of agricultural products can prove to be harmful to humans and domestic animals as these fungi produce a variety of mycotoxins which can eventually occur in food. Acute intoxications with mycotoxins occur regularly in farm animals but, fortunately, are infrequently observed in humans. However, the chronic exposure of humans to mycotoxins occurs regularly. Such exposures are potentially teratogenic and carcmogenic and can suppress the immune system. It is presently impossible to establish safe levels of exposure for most mycotoxins due to scanty epidemiological data and insufficient observations on experimental animals. With respect to aflatoxin all available data point to a real health risk. Risk analysis based on epidemiological observations shows that the liver-cancer risk for individuals in South Africa is potentially increased by continued exposure to the present legally permitted level of aflatoxin in food.

The immune system is central to ensuring the consistency of the body's homeostasis. The state of the body's natural resistance is determined by a set of non-specific protective mechanisms. Lymphocytes and phagocytes are actively involved in maintaining immunity. Lymphocytes recognize the antigens of pathogenic microorganisms, and phagocytes absorb and destroy the pathogens themselves. During the weaning of piglets from sows there is a decrease in the protective forces of their body. During this period, the natural resistance of the piglets is reduced due to the stressful situation caused by changing conditions of confinement, the transition to full feed and lack of sows. The immune system of weaning pigs is relatively weak, so when exposed to environmental and technological stressors, they become susceptible to various diseases. The use of probiotic drugs stimulates the activity of the immune system, prevents stress and immunodeficiency. One of these probiotics is the probiotic of domestic production Protecto-active. It w observed the the influence of the probiotic Protecto-active on the indices of nonspecific resistance of the young pigs organism to the growth. An increase in bactericidal activity of blood serum by 12.10% (P <0.05) and lysozyme activity of blood in the piglets of the experimental group was increased by 3.71% compared to control, which indicates the activation of the body's defenses and the increase in adaptive capacity. An important step in the study of the influence of the probiotic Protekto-active on the state of the immune system is to determine the phagocytic activity of neutrophils, phagocytic index and phagocytic number. In the experimental group of piglets that were fed the probiotic Protecto-active, we found an increase in leukocyte phagocytic activity by 9.0% (P <0.001), a phagocytic index by 51.7% (P<0.001) and a phagocytic number by 24.8% ( P <0.01) compared with the control group. Thus, using a probiotic Protecto-active, all indicators of phagocytosis increase: the number of phagocytes increases, their ability to capture microorganisms and increases their digestive capacity, it increases the bacterial and lysozyme activity of blood serum, which is positively reflected in the immunobiosity. Key words: probiotic, phagocytosis, phagocytic index, phagocytic number, phagocytic activity of leukocytes, cellular immunity, piglets
