The samples for research were collected during their flowering time in June 2018, in the Ismailli region of the Republic of Azerbaijan. Plant samples were fixed in a solution made in 0.1 M phosphate buffer (pH=7.4), containing 2.5 % glutar-aldehyde, 2.5 % paraformal-aldehyde and 0.1 % picric acid. In the next stage was the preparation of block and their filling in Araldite – Epon according to the TEM method. \u0000Results. The leaf is simple, lower part is short-petiolate and upper is sessile. The surface, on both sides of the leaf, is reliefly, and 7–8 conductive veins are clearly visible. The lower and upper sides of the leaf, and also margin, are strewn with multicellular hairs. The calyx of the flower consists of two sepals which grown together at the base, covered with simple multicellular hairs. The stalk in is a long filiform. The corolla of flower consists of 4 petals which grown together at the base and 2 stamens attached to the tube of the corolla.

To study the effect of a dry extract from reishi mushrooms on the activity of lipoperoxidation and oxidative modification of proteins under the conditions of a simulated paracetamol hepatitis in rats. \u0000Materials and methods. The study was performed on white male rats. The animals were divided into 10 groups, each included 6 animals. Acute hepatitis was simulated by the intragastric administration of paracetamol in the dose of 1250 mg/kg once per day (for 2 days). Correction of the pathology induced was performed with a dry extract of reishi mushrooms in the dose of 100 mg/kg of the body weight. The reference drug “Silybor” was administered in the dose of 20 mg/kg of the animal body weight. On Day 3, 7 and 10 from the beginning of the lesion, rats were euthanized using sodium barbamyl. The liver homogenate and blood serum were used for the studies. The activity of free radical oxidation processes under the conditions of acute toxic hepatitis and after the introduction of corrective factors was assessed by superoxide dismutase, catalase activity, the content of TBA-AP and OMP products. \u0000Results and discussion. The development of acute paracetamol hepatitis in rats and damage of hepatocyte membranes are indicated by an increase in the content of TBA-active products, products of oxidative modification of neutral and basic proteins in the serum and liver of animals. Simultaneously, a decrease in the activity of catalase and superoxide dismutase was observed. After correction of the pathology induced with a dry extract of reishi mushrooms a significant increase in the activity of antioxidant enzymes, a decrease in the content of lipid peroxidation products and oxidative modification of proteins in the serum and liver of the affected animals were observed. \u0000Conclusions. It has been experimentally proven that the use of dry extract of Reishi mushrooms in paracetamol hepatitis in rats caused a significant decrease in catalase and superoxide dismutase activity, a decrease in TBA-AP, neutral and basic 2,4-DNPH in the serum and liver of animals.

The studies included two stages, which were carried out on models: stage I – a model of alcohol–prednisolone stomach ulcer in rats, stage II – a model of indomethacin stomach ulcer in rats in accordance with the methodological recommendations of the SEC of the Ministry of Health of Ukraine. The studied concentrate was administered in a dose based on the total content of polyphenols – 9 mg per 100 g of weight. Quercetin at a dose of 5 mg / kg and ranitidine at a dose of 20 mg / kg were used as reference drugs. After replicating the models, a macroscopic examination of the gastric mucosa was carried out and the content of TBA-reactants and reduced glutathione in the stomach homogenate was determined.

Materials and methods. The research was conducted by the method of scientific literature open source analysis: PubMed, Elsevier, electronic resources of the National Library named after V. I. Vernadsky and others. Results. The problem of antibiotic resistance is rightly called the “apocalypse of the XXI century”. P. aeruginosa bacteria are characterized by a very high natural ability to form resistant forms to antimicrobial drugs due to the formation of specific resistance genes, the ability to resist the entry of antibiotics into the cell or remove antibiotics from the cell, and form biofilms. A characteristic feature of the epidemic and epizootic processes of P. aeruginosa, as an opportunistic ubiquitous microorganism is host-pathogenic interaction - the interaction of the pathogen with the host organism. The peculiarity of this bacterium is opportunism and long-term persistence in the body of the host and in the environment. The global trend towards the spread of antibiotic-resistant gram-negative bacteria, including P. aeruginosa, underscores the need to develop comprehensive response strategies targeting all sectors of health. Conclusions. Bacteria P. aeruginosa is classified in 1th Critical Group of the WHO list of resistant to antibiotics \"priority pathogens\". Among the main reasons that contribute to the emergence of resistance are irrational antibiotic therapy in both humans and animals, and the use of antibiotics as growth stimulants in animal husbandry. While more R&D is vital, alone, it cannot solve the problem. To address resistance, there must also be better prevention of infections and appropriate use of existing antibiotics in humans and animals, as well as rational use of any new antibiotics that are developed in future.
