The heavily influence of anthropogenic factors evaluated the level of heavy metals significantly. Cadmium is one of the most widespread toxins of this group and causes irreparable damage to organism and agriculture. Some vital elements exhibit protective properties against cadmium, so the properties of magnesium, zinc and their combinations on changes caused by cadmium exposure were studied. To this end, Wistar rats was used. Our findings suggested that cadmium exposure reduces the body weight gain of animals, increases lipid peroxidation, and also has a negative effect on liver, kidney, and mineral metabolism. The addition of magnesium, zinc and their combinations to feed partially reduces the effects caused by cadmium, while the use of zinc and zinc with magnesium in combination was more effective than the use of magnesium alone.

Toxic hepatitis is common in human and veterinary medicine. One of the methods for modeling hepatitis is the administration of acetaminophen.  In human medicine Acetaminophen overdose is the most frequent cause of ALF (Acute Liver Failure). Acute toxic hepatitis caused by acetaminophen reversible process, however chronic acetaminophen hepatitis, judging by the change in the relative size of the liver and its structure, as well as the level of serum enzymes, is an irreversible process that leads to deep systemic damage to the organism.

This article explores the possibility of minimizing the matrix effect when indicated by indirect enzyme-linked immunosorbent assay (indirect ELISA) in complex plant samples (wheat, corn and silage) from artificially and naturally contaminated samples. The study of the influence of the percentage of methanol (10 -50%) in the extracting mixture on the degree of T-2 toxin extraction showed that all mixtures provide the extraction of mycotoxin from truly positive samples, both when studying the matrix effect and without it. The smallest deviation in the study of mycotoxin content in the control sample containing T-2 toxin at the rate of 100 μg / kg (control sample 100 CSA100) without matrix effect was observed using 40 and 50% methanol, which was 0.98%. However, when using 50% methanol in the extraction of mycotoxin from plant samples, the maximum matrix effect was observed, especially from corn and silage, which is probably due to the maximum extraction and coloring pigments. The value of the matrix effect was in direct proportion to the amount of methanol in the extracting mixture the less methanol, the less the matrix effect. With almost equal deviations in the concentration of CSA100 from plant samples using 40 and 50% methanol, the deviation in CSA100 was 0.98 and -1.32, respectively. It was found that when using a 40% aqueous solution of methanol, a minimal matrix effect is achieved both in simple plant residues (wheat) and complex ones (corn, silage), as well as the maximum extraction of T-2 toxin.

Experimental modeling of acute radiation and burn disease separately and their combination was carried out. It has been established that external total gamma-radiation of white rats at a dose of 7.5 Gr causes severe radiation sickness with characteristic clinical features and high lethality of the irradiated population. It is noted that the degree of thermal injury (burn) is affected by the time of holding on the surface of the body heated to 190 degrees Celsius of a metal plate: its application for 5 seconds causes burn III A degree, 8 - second exposure - III B degree, as evidenced by the timing of formation, rejection of the burn strup and full healing of thermal damage. The aggravating effect of ionizing radiation on the course and the outcome of the combined radiation-thermal pathology is shown.

Based on the conceptual position of radiation parasitology about a certain commonality of the mechanisms of the pathogenic effect of ionizing radiation and biological agents on living organisms, we have determined the conditions for modeling parasitic damage to the body by agents of biological etiology. Irradiation of rabbits at a dose of 8.0 Gy and infection with eimeria at a dose of 85 thousand eimeria oocysts cause severe radiation sickness, aggravating the course of the coccidial process and promoting its generalization, which accelerates the death of animals. The combined radiation and biological damage proceeds quickly and the animals die 6-9 days after the onset of the disease.

Keywords: rabbits, combined lesions, gamma irradiation, acute radiation sickness, coccidiosis, oocysts, Eimeria.

Conducted research on the search and development of antiviral drugs based on compounds of natural origin, with a milder therapeutic effect and low toxicity compared to synthetic drugs. If the twentieth century is rightfully considered the era of antibiotics when many dozens of antibiotics that were active against a number of infectious diseases were isolated from micromycetes, then in the 21st century, research shifted towards macromycetes from various classes. In experiments, a 10% tincture of Coprinus comatus and 5 field cultures of microorganisms of the intestinal group isolated from diarrhea-infected calves (Citrobacter diversus, Enterobacter cloacae, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa) were used. Diurnal cultures grown on nutrient agar were washed off with sterile saline. The bacterial wash was adjusted to a density corresponding to 0.5 according to the McFarland turbidity standard. A bacterial suspension was sown with a lawn on the surface of a Petri dish with meat peptone agar (MPA) in a volume of 1-2 ml, evenly distributed over the surface of the cup by shaking, the excess culture was removed with a pipette. After that, the Petri dishes were dried at room temperature for 15 minutes, then paper discs with a diameter of 6 mm were preliminarily moistened with tincture of the mushroom. The incubation of crops was carried out at t 370 C for 24 hours. As a result of experiments, it was found that the tincture of Coprinus comatus delays the growth of field virulent strains of the pathogens Citrobacter diversus, Enterobacter cloacae, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa on the artificial nutrient medium MPA. The use of tincture of Coprinus comatus as a medicinal product is indicated for intestinal diseases, in the pathogenesis of which pathogenic microorganisms participate: Citrobacter diversus, Enterobacter cloacae, Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa.

Keywords: coprinus comatus, water-ethanol tincture of the fungus, culture test, growth retardation, antibacterial activity.

Anthrax is a particularly dangerous infectious disease common to humans and animals, and continues to pose a serious threat to animal husbandry and health care in most countries of the world.  The disadvantage of this infection is mainly based on the ability of the pathogen to form spores that can persist in the environment for decades.  Numerous anthrax epizootics that have occurred in the past have led to the formation of persistent soil foci of the pathogen, which are currently the main risk factor contributing to the emergence of new outbreaks of the disease.  In this regard, the regular characterization of settlements that are permanently dysfunctional in terms of anthrax is an urgent task that makes it possible to assess the degree of danger of a particular focus of infection.  The purpose of this work was to carry out the epizootological characteristics of the stations, which are stationary for anthrax, located on the territory of the Republic of Tatarstan.  The material for the study was the data of the Main Directorate of Veterinary Medicine of the Cabinet of Ministers of the Republic of Tatarstan, as well as the cadastre of settlements of the republic that are permanently unfavorable for anthrax.  The classification of disadvantaged items was carried out according to the method proposed by B.L.  Cherkassky.  As a result of the study, it was revealed that, according to the classification used, out of 1208 stationary dysfunctional items, 1204 refer to old non-manifest ones that showed their activity more than 10 years ago.  One unfavorable point, the village of Lyuga, Kukmor district, can be classified as an old relapsing one, the last sporadic outbreak of infection in which was registered in 2014.  Three unfavorable points should be classified as new.  Epizootic activity in these points was noted from 17 to 20 years ago, which indicates the stabilization of the situation with the spread of soil foci of infection.

Keywords: anthrax, stationary anthrax unfavorable points, epizootic characteristics, Republic of Tatarstan, soil foci.

The use of organic acids and their salts as acidifiers in diets has a positive effect on the growth rate of farm animals and poultry. The growth rate and other zootechnical indicators depend on the correct selection of organic acid necessary to achieve a certain goal, the dosage of the corresponding acid, as well as the selection of different types of introduced acids to achieve a certain synergy effect and the overall buffer capacity of the feed [8]. Experiments are being conducted in the direction of selecting various combinations with additional substances, such as essential oils, prebiotics, probiotics, etc. their optimal combination to create a universal drug that acts at different levels of acidity. One of the fundamental factors that predispose to the widespread use of such drugs in poultry farming is the lack of restrictions on the use of the resulting final products.

Keywords: organic acids, probiotic, anatomical cutting, muscle tissue, internal organs.
