The study aimed to investigate the protective mechanisms of substance Darmonal and phytin compounds in the experimental model of acute toxic drug-induced hepatitis caused by paracetamol in rats.
The material and methods The research was carried out on white outbred rats of both sexes weighing 140-200 g. Drug-in¬duced liver damage was reproduced by introduction of paracetamol into the stomach in dose 500 mg/kg for 2 days. The test compounds Darmonal, Fitin-C and reference drug Liv.52 were administered for 7 days after hepatitis reproduction in doses 100 mg/kg. The effectiveness and mechanism of action for selected supramolecular complexes in the model of toxic drug-induced hepatitis was made by paracetamol. It was researched that liver protein-synthesizing function was due to the content of total protein and albumin in the blood serum, the excretory and toxic function of the liver by the content of total and direct bilirubin as well as the endogenous intoxication were according to the content of urea in the blood serum, but cytolytic syndrome occurred because of the activity of indicator enzymes (alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in blood serum).
Research results. The study of specific activity of Darmonal in combination with Fitin-C and the reference drug Liv.52 on the model of paracetamol and carbon tetrachloride hepatitis showed that the drugs, being administered in dose 100 mg/kg, had a pronounced hepatoprotective effect.
This article presents the results of a study of the hepatoprotective properties of the herbal drug darmonal in combination with phytin compounds in experimental animals (rats) with experimental hepatitis caused by SS14 intoxication. The obtained research results showed that darmonal in combination with phytin compounds increases the synthesis of total protein and normalizes the composition of protein fractions of blood serum. Both studied drugs have a high level of hepatotropic effect. The combination of darmonal and fitin-C was the most effective. According to this effect, they were superior to the hepatoprotective drug LIV-52.
The purpose of the study was to determine and evaluate the features of morphological changes in the liver parenchyma of 5-month-old white outbred rats under the influence of anti inflammatory drugs under conditions of polypharmacy.
The object of study for experimental studies was taken 250 white male rats weighing 200-250 g.
The scientific novelty of the research is as follows: polypharmacy of anti-inflammatory drugs negatively affects all parameters of liver structures. Under the influence of polypharmacy, there is a decrease in the absolute mass of the liver, volume and morphological parameters of the liver parenchyma. The decrease in morphometric parameters depends on the number of drugs in polypharmacy; under conditions of polypharmacy, the state of the hepatic capillaries and internal bile ducts, as well as biological membranes, was studied, as a result of which the structural structure of the liver, the development of destruction of the hepatic tissue were studied, and the morphofunctional foundations of this condition were shown.
Implementation of the research results. Based on the obtained scientific results, the morphofunctional characteristics of the liver of rats in the norm and under the influence of polypharmacy were determined:
Approved methodological recommendations: "Methodology for determining the morphometric parameters of the liver during polypharmacy of anti-inflammatory drugs" (Conclusion No. 8n-r / 265 dated 14.03.2022 of the Ministry of Health of the Republic of Uzbekistan) and "Methodology for determining the morphometric parameters of the liver during polypharmacy of anti-inflammatory drugs" (Uzbekistan, Conclusion of the Ministry of Health of the Republic of Uzbekistan No. 8 n-z 180 of 2022), electronic program No. DGU 1038 "Program for studying the comparative characteristics of morphological changes caused by polypharmacy in the liver."
The scientific results obtained in the study of morphological and functional properties and morphometric changes in the structure of the liver under the influence of polypharmacy have been introduced into the practice of the Samarkand branch of the Republican Specialized Oncological and Radiological Scientific and Practical Medical Center of the Samarkand City Medical Association (Order of the Ministry of Health of the Republic of Uzbekistan dated March 14, 2022, 8n-r / 265-No. and conclusion No. 8 n-z 180 of 2022). The implementation of the obtained research data allows developing methods for early diagnosis, treatment and prediction of organopathology by morphological parameters, improving the quality of life and reducing the number of complications.
