The composition of the drug "Hepaton" includes many bioactive compounds that provide the antioxidant properties of the drug, manifested by the neutralization of reactive oxygen species (ROS) with the breakaway chain free radical reactions. The aim of the study was to determine the effect of the Hepaton preparation on lipid peroxidation reactions in laboratory rats. Evaluation of the antioxidant effect of the drug was carried out on twenty laboratory rats of both sexes with a body weight of 180-220 g, divided into 2 groups. Acute toxic hepatitis in rats was induced by a single intragastric administration of 1.0 ml of a dichloroethane solution. At the same time, rats of the experimental group (n = 10) 1 hour before the introduction of di-chloroethane were injected with a solution of the drug “Hepaton” in the amount of 10 ml / kg body weight and then 1 time per day for 21 days after the use of toxicants [1]. On the 21st day after the administration of toxicants, a blood was drawn for a biochemi-cal study, which took into account the pa-rameters of the antioxidant system (diene conjugates (DC), ketodienes (CD) and malondialdehyde (MDA), as well as the level of endogenous intoxication (according to the content of MSM). Based on the results obtained, it can be con-cluded that the use of “Hepaton” in modeling acute toxic hepatitis made it possible to re-store the disturbed homeostasis of the labora-tory animal organism, the structure and in-tegrity of the hepatocyte membranes, inhibit lipid peroxidation as one of the links in the pathogenesis of hepatitis, stimulate antioxi-dant defense and power the endogenous anti-oxidant system of the body, bile formation and biliary excretion, as well as activate the reparative processes of the liver tissue at the cellular and intracellular levels.
This article is devoted to the pathologies of the hepatobiliary system in highly productive imported Holstein cattle against the background of metabolic disorders. The basic principles of diagnostics of hepatopathies, which include a biochemical blood test and ultrasonographic studies of the liver and gallbladder in the studied animals, are considered. The dynamics of changes in the parameters of alanine aminotransferase, aspartate aminotransferase and total bilirubin in highly productive cattle, depending on the physiological state of animals, was analyzed, as well as the main ultrasonographic changes in the liver of cows with metabolic disorders.
The article presents data on the periods and main reasons for the retirement of highly productive Holstein cattle at dairy farms, and offers the production of improved therapeutic and preventive measures for metabolic disorders in cows.
Among the many environmental and industrial factors that adversely affect the soil, the pollution with heavy metals and mycotoxins occupies a special place in livestock breeding. This study aimed to demonstrate methods of treating and pharmacological correction of a toxic state intensified by heavy metals and mycotoxins in cattle using native drug as mycotoxin-deactivating feed additive. A total of 20 highly productive Holstein cows aged 3-4 years were divided into 2 groups, based on clinical and biochemical parameters. The experimental group (n=10) fed a diet supplemented with 4% sorption complex and a drug based on Silybum marianum and ursodeoxycholic acid as a hepatoprotector named “Hepaton-vet”. The control group (n=10) was injected with a complex of sorbents (consisting of perlite, vermiculite, and polyphepan in equal proportions) at a dose of 4% of the daily intake of food, and the rest of the treatment was carried out with the help of daily infusion therapy. So in the feed samples, only the T-2 and Deoxynivalenol (DON) indicators exceeded the normal value by 1.66% and, 3%, respectively. Thus, the practical efficiency concerning T-2, aflatoxin and Deoxynivalenol were to 100%, 86%, 18%, respectively. Cadmium in compound feed was lower by 44%, in comparison with the maximum permissible concentration, followed by 53.3% in hay and 78% in silage. The amount of lead in compound feed and silage was 78%, and it was 35% in the hay. In conclusion, the use of a complex of sorbents, together with newly developed component “Hepaton-vet”, led to positive results, allowing for the identification of several effects that influenced the metabolic processes in the liver, which was confirmed by the results of morpho-biochemical blood tests and clinical diagnostics of the animals' condition.
The combined use of hepatoprotectors and phytosorbents in theory is a promising method of pharmacotherapy of comorbid pathologies, as it creates the possibility of presenting them as the result of an extended search for the most relevant forms of manifestation of metabolic disorders, the results of which made it possible to identify general patterns of development and, accordingly, the main directions for their leveling.It was revealed that the main pathogenetic trend is the failure of metabolic processes in the gastrointestinal tract, which reduces the efficiency of feeding and causes a decrease or fluctuations in productivity (or product quality), the subsequent accumulation of products of disturbed metabolic processes with toxic properties - the development of a local syndrome of endogenous intoxication, a violation of the processes of cavitary and symbiotic digestion in the gastrointestinal tract, with increased alimentary insufficiency, functional overload of the digestive organs and primarily the liver, imbalance of the microbiota and local barrier mechanisms, generalization of the pathological process in the form of the development of systemic endogenous intoxication with the corresponding toxic depression of immunity, functions of organs and body systems, including including dysfunctions and the development of pathology of the hepatobiliary system, in the form of systemic metabolic disorders with the occurrence of a secondary deficiency of nutrients and biologically active substances, acid disorders butalkaline balance and dystrophic phenomena.The main purpose of this article is, based on the analysis of literary sources, to identify the pathogenetic basis for the combined use of drugs from the hepatoprotector groups and phytosorbents.We searched for original studies in the scientific databases PubMed, Elsevier Science (Scopus) and Clarivate Analytics (Web of Science) over the past 20 years to identify the features of the above processes, after which a formalized content analysis of the found publications was carried out.A better understanding of the various mechanisms involved in pathogenesis involving the liver and intestinal microbiota will contribute to the development of improved pharmacological approaches to the treatment of these pathologies.
