The article discusses the issues about the effect of the Armadin on the hepatic transaminase in rats with acute generalized peritonitis on the background of diabetes mellitus. The experiment was performed on 48 white male adult rats, which were divided into two groups. The experimental group – animals with simulated acute generalized peritonitis against the background of streptozotocin-induced diabetes with the drug “Armadin” (ethylmethylhydroxypyridine succinate) application (n=24). The control group – animals with simulated acute generalized peritonitis against the background of streptozotocin-induced diabetes without pharmacocorrection (n = 24). Diabetes mellitus was simulated by a single intraperitoneal injection of streptozotocin at the dose of 60 mg/kg. Acute generalized peritonitis was induced with 10% faecal suspension in a dose of 0.5 ml per 100 g of animal weight in the abdominal cavity of laboratory animals by puncture method. Every day for 6 days, rats of experimental group received the drug “Armadin” at the doses of 100 mg/kg. We found a probable decrease in aminotransferase activity on day 3 of the study in rats of the experimental group after administration of Armadin. Thus, ALT activity decreased by 26.7%, and AST activity – by 25.9% compared to the control group. On the 7th day of the study, the activity of ALT in the blood of rats of the experimental group decreased to 0.50 ± 0.03 mmol/l, which was 49.5% lower than the control group of rats in this period of the experiment. Similar changes are observed in the study of AST activity, where, accordingly, it decreased by 48 % relative to control. The positive effect of the drug "Armadin" on the body of rats, with AGP on the background of STZ-induced diabetes, is manifested by the restoration of the functional state of the liver.

Introduction. There are evidence that oxidative stress is involved in the pathogenesis of the acute generalized peritonitis and diabetes mellitus.The aim of study was to examine levels of the products of lipid peroxidation and the antioxidants in rats with experimental acute generalized peritonitis against the background of streptozotocin-induced diabetes.Material and methods. The experiment was performed on 66 adult white male rats weighing 220-300 g. Diabetes mellitus in experimental animals was simulated by a single intraperitoneal injection of streptozotocin (Sigma) at the dose of 60 mg/kg. Acute generalized peritonitis was induced with 10% faecal suspension in a dose of 0.5 ml per 100 g of animal weight in the abdominal cavity of laboratory animals by puncture method. The thiobarbituric acid reactive substances (TBARS), lipid hydroperoxides (LOOHs), superoxide dismutase (SOD) activity, catalase (CAT) and ceruloplasmin (CP) were estimated and compared.Results. Our results showed that during all stages of development of acute generalized peritonitis on the background of streptozotocin-induced diabetes there is the LOOHs decrease and the TBARS increase. We observed statistically significant inverse correlations between the level of LOOHs and SOD in the animals of subgroup 1 (r = -0.88; p <0.05) and inverse correlations between the TBARS level and the SOD level in the subgroup 3 of animals (r = -0.74; p <0.05). We also found a statistically significant inverse correlation between the CAT level and the TBARS level (r = -0.86; p <0.05) and between the CP level and the TBARS level in the blood of animals in the subgroup 3 (r = -0.87; p <0.05).Conclusion. Negative statistically significant correlations between the TBARS level and the antioxidants (SOD, CAT, CP) in the blood of animals with acute generalized peritonitis on the background of streptozotocin-induced diabetes indicate a predictor role of lipid peroxidation processes in the depletion of antioxidant resources

The evaluation of renal measurements such as length, width and thickness, volume is important in the diagnosis and treatment of many renal disorders, since there is a close relationship between the sizes of the kidneys and its function. The purpose of the study was to establish and compare during the postoperative period changes in the mass and sizes of the kidney left after nephrectomy in the sexually mature male rats. An experimental study was carried out on 84 sexually mature white male rats weighing 178-194 grams. Animals were divided into two groups: control (42 rats) and experimental (42 rats). In the control group, the animals under ketamine anesthesia were followed by an abdominal cavity dilution, after which the abdominal wall was applied in a row. All animals of the experimental group performed surgical intervention – nephrectomy of the left kidney. The animals were withdrawn from the trial by intra-pleural administration of thiopental-sodium 50 mg/kg after 7, 14, 21, 30, 90 days after nephrectomy. Macroscopic evaluation and description of the kidneys of animals was performed after their removal. Their weight was determined on the laboratory scale of HLR-200 up to 0.1 mg, and the length, width and thickness of the organ were measured with the help of a caliper to an accuracy of 0.05 mm. Calculated the volume of the kidney. The statistical analysis of the obtained results was carried out using the program STATISTICA 5.5 using parametric methods for evaluating the results. It was established that the mass, length, width, thickness and volume of the kidney of animals in the experimental group, as compared with the control group, were statistically significantly higher in all terms of observation. The fraction of the growth of the width and thickness of the single kidney of animals in the experimental group compared with the control animals in the animals was statistically significantly greater than the proportion of kidney growth during the postoperative period. It was found that the largest increase in the mass and thickness of the kidney, as compared with the control group, was observed after 30 days of the postoperative period, and the greatest increase in the length and width of the kidney, as compared with the control group, was observed after 14 days of the postoperative period.

Objective: to develop and justify the application of a new experimental method of the simulation of liver cirrhosis in laboratory animals. Material and methods. The simulation of liver cirrhosis was performed on 11 eugamic white Wistar male rats with the body weight of 203.5 ± 22.2 g (experimental group). The control group consisted of 12 healthy laboratory animals. Acute toxic liver injury resulting in cirrhosis was caused by means of the intraperitoneal administration of 50 % solution of carbon tetrachloride (CCl4) in olive oil on the first day of the experiment at a dosage of 0.1 ml of CCl4 + 0.4 ml of olive oil per 100 g of the body weight of the animals, on the second day of the experiment - 0.3 ml of CCl4 + 0.2 ml of olive oil per 100 g of the body weight of the animals. For synergism and potentiation of the hepatotoxic effect of CCl4, the animals daily had free access to 10% ethanol solution. The duration of the experiment was 65 days. The clinical and laboratory parameters were evaluated, the histological assessment of the preparations was carried out. The obtained data were compared with the same parameters of the control group of the animals. Results. The reproducibility of the model was 81.8% (9 animals). The values of the biochemical blood analysis indicated statistically significant increases in the levels of total bilirubin, serum transaminases (AST, ALT), creatinine, a decrease in the glucose level in the animals of the experimental group. The complex morphological confirmation of liver cirrhosis in progress was obtained. Conclusion. The proposed method of the liver cirrhosis modeling correlate with the values of the biochemical blood analysis, pathological changes in the tissue of the liver and internal organs of liver cirrhosis in humans. With the help of the original model, it is possible to investigate the pathogenesis and effects of various groups of pharmacological drugs on liver cirrhosis and its complications (acute blood loss associated with the syndrome of portal hypertension).

The processes of compensatory hypertrophy of the kidney to the period of puberty are insufficiently studied. Changes in renal parameters after contralateral removal are of scientific interest. The purpose of the study was to establish and compare changes in organometric parameters of the kidney that remained after nephrectomy in non-sexually adult male rats and in sexually mature male rats. Experimental study was performed on 84 non-adult white male rats weighing 53-71 grams, which were kept on a standard vivarium diet. All animals were divided into two groups (42 in each): the first - control, the second - the experimental group. In the control group, the abdominal cavity was opened under ketamine anesthesia, after wich the abdominal wall was sutured in layers. All animals of the experimental group performed surgical intervention - nephrectomy of the left kidney. Animals were withdrawn from the trial by intra-pleural administration of thiopental-sodium 50 mg/kg after 7, 14, 21, 30, 90 days after nephrectomy. Macroscopic evaluation and description of the kidneys of animals was performed after their removal. The statistical analysis of the obtained results was carried out using the “STATISTICA 5.5” program, using parametric and non-parametric methods for evaluating the obtained results. It was found that in the immature rats, the weight of animals in the experimental group (after nephrectomy) was statistically significantly lower in all terms of the observation compared to the control group, and the weight of the kidney of animals in the experimental group, on the contrary, was statistically significantly higher in all terms of observation. The length, width, thickness, volume of kidneys of animals of the experimental group, as well as the magnitude of increment of these parameters with each term of observation are determined. The greatest increase in organometric parameters of the kidney was observed after 30 days of the postoperative period (p<0.05). Subsequently, on the 60th and 90th day, the magnitude of the increase in organometric parameters of the kidney significantly decreased. The index of hypertrophy of the kidney remained unpaired by nephrectomy, which varied from 52.24% to 63.21%. The highest rates of hypertrophy were observed between the 21st and 30th days.

The aim of the study was to study the structural changes of the intestinal epithelial barrier in the duodenum in burn injury of skin in rat under experimental streptozotocin-induced diabetes mellitus. The study was carried out on laboratory white adult rats-males weighing 180-210 g. The control group consisted of 21 animals without somatic pathology, the first experimental group was 21 rats with burn skin injury, the second experimental group was 21 rats with burn skin and experimental streptozotocin-induced diabetes mellitus. The experimental diabetes model was reproduced by administering streptozotocin to the rats intraperitoneally at a single dose of 50 mg/kg. Thermal burn skin damage in rats corresponded to II – A-B degrees of dermal surface burn (according to the old classification III – A degree) with a total area of 21-23 % of the body surface with the development of burn shock. Duodenum was selected for morphological studies, fragments of which were processed by conventional methods of light and electron microscopy. The main criteria for assessing damage to the duodenal mucosa enterocytes were the results of a study comparing histological and ultrastructural data in dynamics at 7, 14, and 21 days after skin burns. The results of the studies showed that the base of damage to the intestinal epithelial barrier of the duodenum are deep destructive changes, which after 21 days (in the stage of septicotoxemia), as a rule, are not reverse and develop on the background of significant intoxication of the body. There was a decrease in the number of tight junctions in the intestinal epithelial barrier of the duodenum of rats of the first and second experimental groups and a loss of ordering (acquisition of some chaotic nature) of their localization as the time after burn injury increased. For the most part, the intestinal epithelial barrier loses the integrity of the cellular component with partial preservation of the basement membrane (the first occurs both due to necrosis of the enterocytes with a brush border and due to complete destruction of goblet cells). In all cases, defects exist in the intestinal epithelial barrier, which are potential pathways for paracellular translocation of the pathogenic contents of the duodenum. It is not inconceivable that part of this intestinal pathogenic content can be translocated also by partially damaged cells. Evidence of the latter is the presence of microbial bodies in the cytoplasm of cells with partially destroyed plasmalemma (but preserved organelles and nucleus). An adaptive mechanism for ensuring the repair of damaged enterocytes is selective autophagy, which acts as a factor in the recycling of destroyed organelles and the cytoplasmic matrix, aimed primarily at maintaining cell viability.

The work is devoted to the study of structural changes of enterocytes in the mucous membrane of the duodenum in a burn injury of the skin of a rat under conditions of experimental streptozotocin induced diabetes. The study was carried out on laboratory white adult rats-males weighing 180-210 g. The control group consisted of 21 animals without somatic pathology, the first experimental group consisted of 21 rats with skin burn injury, the second experimental group cleared 21 rats with skin burn and experimental streptozotocin induced diabetes. A model of experimental diabetes mellitus was reproduced by administering streptozotocin intraperitoneally once in dose of 50 mg/kg to rats. In an experimental simulation of a skin burn, two copper plates in the form of an ellipse were kept in water at 100oC for 10 minutes and, under ether anesthesia conditions, were applied simultaneously symmetrically on both exposed parts of the body of rats with an exposure for 10 seconds. Burn skin damage in rats was II-AB degrees – dermal surface burn (according to the old classification III-A degree) with a total area of 21-23% of the body surface with the development of burn shock. For morphological studies, the duodenum was taken, fragments of which were processed using conventional light and electron microscopy. The main criteria for assessing damage the enterocytes of the duodenal mucosa were the results studies of histological and ultrastructural data over 7, 14 and 21 days after a skin burn. The results of the studies showed that the damage of the enterocytes of the duodenal mucosa is based on deep destructive changes, which after 21 days (at the stage of septic toxemia), as a rule, are not reversible and develop against the background of significant intoxication of the organism. In the mucous membrane of the duodenum with burn injury of the skin associated with diabetes mellitus, there is a deterioration of the manifestations of the adaptive response and prolongation of destructive processes, accompanied by a violation of intercellular interactions in cytoarchitectically modified and deformed villi and crypts.

Repeated introduction into the body of an animal of a medicinal substance can lead to its accumulation in the tissues of the body. Therefore, knowledge of the cumulative properties of substances or conditions that may lead to cumulations, are especially important for understanding the pathogenesis of intoxication, because this phenomenon often lies at the basis of acute and chronic poisoning. The purpose of the work was to study the degree of cumulation of the “Bendamin” preparation in the body of white rats. The properties of the cumulative drug were studied in 12 white rats weighing 150–160 g. Rats were divided into 2 groups: control and experimental. To determine the cumulative properties of Bendamin, it was administered to laboratory animals starting at a dose of 0.1 DL50, with a sequential increase in the dose of 1.5 times every 4 days. It was found that the cumulative coefficient of Bendamin was 8.31 units, indicating that the drug does not exhibit cumulative effects. In determining the mass coefficients of the internal organs in the animals of the experimental group, the tendency to increase the weight and liver mass coefficients was determined, respectively, by 5.2 and 5.1%. The weight ratio of the heart of the animals of the experimental group increased by 5.7% relative to the control group. After studying the morphological parameters of blood of rats at 24 days of the experiment for studying the cumulative properties of the “Bendamin” drug, an increase in the number of erythrocytes to 6.13 ± 0.27 T/L, white blood cells to 8.42 ± 0.54 G/L and hemoglobin up to 132.4 ± 2.44 g/l. In the analysis of leukocyte profile in rats, there was a decrease in the number of eosinophils and monocytes, respectively, at 1.1 and 1.3% relative to the control group. The number of lymphocytes in the blood of the experimental group of rats increased by 1.5%, while neutrophils by 0.9% compared to the control. When studying the level of total protein, its small increase was determined by 5.2%. The activity of aminotransferases in the blood serum of experimental rats on the 24th day of the experiment for the study of cumulative properties of the drug also increased by 13 and 8% relative to the control group. Also, creatinine and total bilirubin levels in their rat blood were decreased by 3.1 and 8.8%, respectively.

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.
