3 Gerunov T.V., Gerunova L.K., Fedorov Yu.N. Classification of the officinal immunomodulators listed in the state register of medicines for veterinary use

At present time the range of immunomodulators for veterinary use has been considerably diversified. However there is no common classification of immunomodulators in veterinary medicine. The objective of this research was both classification and a comparative assessment of immunomodulators registered in the territory of the Russian Federation. Thus, the analysis of the State register of medicines for veterinary use was carried out. Of all drugs authors graded 47 immunomodulators which were divided into groups by origin: cytokine-type medications  (interleykins and interferons), tissue derived medications (preparations derived from a placenta, lien and colostrums), bacterial drugs (bacterial peptidoglikans and polysaccharides, combined drugs and  immunoprobiotics), yeast products, herbal medicinal products, synthetic medicines and homeopathic medicines. Authors pointed the necessity of continuing researches in the field of clinical pharmacology of immunoactive agents to obtain reliable scientific information about efficiency and safety of certain medications. Key words: immunomodulator, classification, immunostimulation, immunopharmacology, pharmacodynamics, the action mechanism, medicines for animals, the state register.

27 Blokhin A.A., Zhivoderov S.P. Manifestation of avian influenza H5N8 in Russia

The article presents information on the spread and manifestation character of avian influenza caused by a subtype H5N8. The temporal and spatial boundaries of the spread of avian influenza have been determined. It is shown that, starting from 2016, the disease tends to spread throughout the country. It is established that an important role in the introduction and the spread of avian influenza is played by such risk factors as insufficient level of biological protection, which is expressed in the absence of a clear zoning of production areas, conditions for nesting wild birds, the absence of sanitary discipline and the fixing of person and the intersection of routes traffic and human flows, the lack of vaccination of susceptible livestock, the close inter connection of poultry farms and private farms. It is suggested, that high tourist activity in a number of regions of the country can contribute to the introduction of the influenza virus of a subtype H5N8 by tourists from the countries of South-East Asia. We believe that the mortality of birds over 13,8% is the reason to suspect the presence of an infectious disease, including avian influenza.The dynamics of pathoanatomical changes characteristic of subtype H5N8 is shown, manifesting as lesions of mucous and serous membranes of the digestive and ovarian organs, an increase in the spleen and a violation of the permeability of the vascular bed. Laboratory studies have shown that influenza virus subtype H5N8 has high pathogenicity, i.e., the intravenous pathogenicity index is 2.85. Key words: avian influenza, H5N8, monitoring, quarantine.

46 Trebukhov A.V. Clinical and biochemical aspects of ketosis in dairy cows

In the conditions of intensive livestock production even minor errors in feeding, maintenance and operation conditions often lead to the development metabolic diseases. Among them ketosis of dairy cows takes one of the first places by incidence. The purpose of research is to study dependence between clinical severity of ketosis syndrome in cows and level of total ketone bodies in the blood. The study was conducted on dairy cows with ketosis diagnosis. During study, the cows were subjected to clinical and biochemical examination. Biochemical blood analysis was focused on determined the following values- total ketone bodies (TKB), beta-hydroxybutyric acid (BHB), acetoacetic acid and acetone (AcAc), BHB/AcAc ratio, glucose and reserve alkaline level of blood. The results of the study show that ketosis of cows had clinical manifestations through the acetonemic syndrome – 65 % of cases, and more rare through the gastroenteric (21%) and hepatotoxic syndromes (14 %). The comparison of the ketone body levels and ketosis syndromes has revealed that the acetonemic syndrome is accompanied by the greatest TKB and BHB/AcAc ratio values. The gastroenteric syndrome is accompanied by intermediate TKB, BHB and AcAc values, and the minimum levels of glucose and alkaline reserve. The hepatotoxic syndrome is accompanied by the minimum TKB and BHB/AcAc ratio values, and the greatest glucose and alkaline reserve levels as compared to the other syndromes. Key words: cows, diagnostics, ketosis symptoms, beta-hydroxybutyric acid, acetonemia.

49 RydenkoA.A. Citokine profile of blood serum in dogs with mitral valve endocardiosis

Serum concentrations of interleukins 1α, 6, 8 and tumor necrosis factor-α in serum of dogs with mitral valve endocardiosis is higher than in clinically healthy animals. The levels of these proinflammatory cytokines are especially high in dogs with pulmonary edema, left atrial remodeling and cardiogenic cachexia, and also they positively correlate with the functional class of chronic heart failure and the size of the left atrium. Their activation plays an important role in the pathogenesis of endocardiosis. Key words: interleukins, dog, tumor necrosis factor-α, cytokines, endocardiosis.

60 Vertiprakhov V.G., Titov V.Y., Gogina N.N., Grozina A.A. Changes of the activities pancreatic enzymes and development of inflammation as a responses to experimentally mycotoxicosis in broiler chicks

The experiment was performed on broilers (cross “Smena-8”) with duodenum fistula. It was found that dietary T-2 toxin tends to accumulate quantitatively within the body while the accumulation of HT-2 toxin up to 65% depending on its dietary concentration. No significant changes in the activities of pancreatic enzymes in serum in response to dietary exposure to the mycotoxins were found while amylolytic and proteolytic activities in the duodenal digesta were significantly increased. The concentrations of serum nitroso compounds evidenced that the exposure to mycotoxins can promote inflammation in chicken. Key words: broilers, duodenal digesta, mycotoxins, pancreatic enzymes, serum nitroso compounds.
