3 Naymanov A.H., Ustinova G.I., Tolstenko N.G., Vangeli E.P., Kucheruk O.D., Kalmykov V.M. Simultaneous tuberculin test for the selection of reacting animals and the diagnosis of tuberculosis

The analysis of numerous and long-term studies of simultaneous breakdown with PPD tuberculin for mammals and CAM is presented in order to differentiate allergic reactions, select animals for diagnostic slaughter and establish a diagnosis of tuberculosis. The main advantages and disadvantages of the simultaneous tuberculin test are indicated. It has been established that at the present stage of the fight against cattle tuberculosis, there is no need to differentiate the herd of animals by the method of group accounting of allergic reactions and use the cumbersome table for determining the reliability of the reactions, and when revealing animals that respond to tuberculin, to re-examine the entire herd of animals with a simultaneous breakdown. Therefore, due to the fact that in accordance with the current regulatory documents the diagnosis of tuberculosis is not made according to the indications of intravital allergic studies, the simultaneous test should be used only for the purpose of selecting reacting animals for diagnostic slaughter. Key words: tuberculosis, cattle, nonspecific reactions, allergic studies, simultaneous testing, PPD tuberculin for mammals, a complex allergen from atypical mycobacteria (СAM), recording and evaluation of allergic reactions, determining the significance of differences in reactions.



7 Lashin A.P., Simonova N.V. Comparative effectiveness of succinic acid and Reamberin in the oxidative stress in newborn calves

In experimental conditions the possibility to correct free radical lipid oxidation of calves’ organism membranes was studied with the introduction ofthe succinic acid and of the succinate containing drug called Reamberin (Research and Technological Pharmaceutical Firm POLYSAN, Saint Petersburg, Russia). The animals were divided into 3 groups and each of them had 15 calves: the control group animals which were held in standard conditions; the experimental group in which animals had a daily oral intake of the succinic acid in a dose of 50 mg/kg; the experimental group in which animals had a daily by intravenous injection of the the drug Reamberin of 60 ml of 1,5 % solution for infusion. The introduction of the succinic acidto calves contributes to the reliable decrease in the blood of lipid hydroperoxides by 23 %, of diene conjugates – by 17 %, and of malonic dialdehyde by 20 % in comparison with the animalsof the control group. The introduction of the succinate containing drug called Reamberin to calves in the conditions of oxidative stress contributes to the reliable decrease in the blood of lipid hydroperoxides by 33 %, of diene conjugates – by 26 %, and of malonic dialdehyde by 26 % in comparison with the animalsof the control group. While analyzing the effect of the succinate containing drugs on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the bloodof animals was reliably higher by 29 – 43 %, of vitamin E by 17 – 43 %, of glucose-6-phosphate dehydrogenase by 21 – 29 %, of catalase by 25 – 31 % in comparison with the same parameters of the calves of the control group. So, the application of the succinate containing antioxidants in newborn calvesleads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity.The intravenousintroduction in animals of the reamberin prevents the accumulation of lipoperoxidation products and increases the activity of main components of the antioxidant system in calves’ blood plasma, which indirectly exceeds similar effect of succinic acid in the conditions of oxidative stress. Key words: antioxidant system, calves, diene conjugates, lipid hydroperoxides, biological membranes lipid peroxidation, malonic dialdehyde, oxidative stress, products of peroxidation,Reamberin, succinic acid.

37 Brigadirov Yu.N., Kotsarev V.N., Sachnina L.Yu., Manzhurina O.A., Lobanov A.E., Likhacheva I.L. The influence of alpha- and gamma-interferons on immune-biochemical status, microbiocenosis of the genital tract and reproductive function of sows

The aim of the researches is to study the influence of alpha- and gamma-interferons on the immune-biochemical status and microbial landscape of sow genital tracts during different physiological periods of the reproductive cycle. Studies on pharmacological effects of pig recombinant alpha- and gamma-interferons were carried on 27 sows, which were taken in an experiment on 103 – 105 days of pregnancy, and divided into two groups. The first group of sows (n=13) were given parenterally alpha- and gamma- interferons (10 ml) per animal three times with 48-hour intervals 8 – 10 days before farrowing. The second group of animals (n=14) did not take drugs (control). The indicators of immune and bio-chemical status, components and quantities of the sows’ genital tract microbiota during pregnancy, for 3 – 4 days of lactation, and before weaning of piglets, were determined. It was found that parenterally application of alpha- and gamma-interferons in sows reduces the pressing of opportunistic pathogenic microflora and pathogenic microflora, induces the stabilization the normal flora of the genital tract, increases the immune-biochemical status and improves the reproductive performance of animals. Key words: saws, piglets, blood, immune-biochemical status, microbiota, alpha- and gamma-interferons, reproductive performance.


42 Nariznyi A.G., Dzhamaldinov A.Ch., Anisimov A.G. Effects of different diluents on boar semen quality

The possibility for the use of the semen plain salt diluents compared to the expensive multicomponent media for the semen dilution and short-term storage within 2 – 4 hours has been studied. The efficiency of such an application process was ascertained, since there was an insufficient decline in the values of the semen qualitative parameters. A comparison of two methods of insemination with the use of these diluents also proved the reason of their application. In addition, the fraction method for insemination for pigs was more efficient. The research into the causes of reduction in the active sperm numbers per insemination dose for the ewes proved the advantages of the citrate-and-sulphate-based extender. The best performance indicators were recorded in this group of ewes. The plain salt diluents as the semen extenders can induce a 1,5 – 2,0-fold decrease in the active sperm count per dose, when it is required for insemination of the ewes. Key words: media, boars, sows, artificial insemination, efficiency.

49 Popova O.S., Baryshev V.A., Rogacheva E.V. Industrial tests of the new phytorial surgery complex

The object of the study was a new phytosorption complex, developed at the Department of Pharmacology and Toxicology of the St. Petersburg State Medical University. Phytosorption complex contains as a formative substance a set of sorbents, which are a matrix for extracts of plants, provides their delivery to the animal's body. In the intestine, ion metabolism is carried out, sorption is additionally carried out, and toxic substances are eliminated from the body. To study the effect of the phytosorption complex on the organism of piglets of weaners, two groups of animals were created, experimental and control, with 20 heads in each. Piglets of the experimental group in addition to the standard diet were administered a new phytobiotic complex, at a dose of 1 g/kg, for 10 days. The animals of the control group were given food, according to the physiological norms of feeding without any additives. At the beginning and end of the experiment, the pigs of both groups were weighed. The weight of animals at weaning was 7,6±1,1 kg in the experimental group, and 8,7±1,7 kg in the control group. Thus, the increase in body weight was in the experimental group in relation to the control, 4 %. We conducted a hematological analysis of the blood, assessed the number of case cases in the groups, the incidence of diarrhea, and analyzed the results of changes in body weight at the beginning and end of the experiment. When analyzing blood, there was a tendency to increase the hemoglobin and erythrocyte content, due to the increase in metabolic processes. It was found, as well as an increase in the total protein and alkaline phosphatase in the blood. Thus, the optimal dose has been confirmed to correct weaning stress and increase the productivity of weaned pigs. Key words: piglets-weaners, stress, phytosorption complex.


52 Shumilin Yu.A., Nikulin I.A. Analysis of heart rate variability in horses and dogs by the method of histograms

When using histograms to estimate heart rate variability, the tolerance field limit for dogs is 0,5≤RR≤0,85, and for horses 1,5≤RR≤2,5. If the entire histogram is within the tolerance field, the process is statistically stable and requires no intervention. Due to statistical analysis and graphical reflection of the available quantitative information about the duration of RR intervals, it is possible to establish the nature, degree and cause of heart rate variability in healthy and sick animals, which is not always possible with the traditional method of electrocardiogram analysis. The proposed method of constructing a histogram by the sample size of 200 cardiac cycles is quite representative, which makes it possible to say with confidence that three important parameters of the histogram – its center, width and shape – are representative for the whole process. Key words: dog, horse, electrocardiography, heart rate variability, sinus arrhythmia.

59 Andreeva E.Yu., Rodionova T.N., Strogov V.V. Determination of subchronic toxicity of the mineral complex based on iron, zinc and copper nanopowders

Studies have carried out an assessment of the subchronic toxicity of the mineral complex based on iron, copper, and zinc nanopowders. An injection form of the drug was developed, which consists of the following components: iron, zinc and copper nanopowders, propylene glycol, Tween 80 and distilled water. The experiments were performed under standard laboratory conditions on non-linear white rats in an equal sex ratio. The animals were divided into three experimental groups, depending on the dose of the preparation: 75, 250 and 500 mg/kg. The drug was administered intraperitoneally for 30 days, 7 times a week, followed by evaluation of the morphological and biochemical parameters of the blood of white rats on days 14 and 30 of the experiment. The absence of negative effects of subchronic introduction of the drug on hemo- and erythropoiesis in the body of white rats was revealed, which is confirmed by an increase in hemoglobin content and the number of erythrocytes relative to the control by 1,3 and 1,2 times, respectively, when exposed to a dose close to therapeutic. An increase in the activity of the AST and ALT enzymes, as well as the presence of hyperglycemia with the administration of the drug in high doses by the end of the 14th and 30th days of the experiment compared with the control, was noted. A decrease in the total protein concentration to 46,7 g/l and albumin to 29,8 g/l compared with the control (67,0 g/l and 34,3 g/l, respectively) was noted with the administration of the drug at a dose of 500 mg/ kg. The revealed changes can presumably be due to the duration of the use of the drug in large doses, and also indicate the initial stage of intoxication in the internal organs of white rats. Key words: metal nanopowders, iron deficiency anemia, subchronic toxicity.
