    Abstract Urolithiasis and inflammatory diseases of the urinary system are of great importance in recent times. Only urolithiasis affects about 15 % of the population. Therefore, the development of new domestic drugs for the treatment of urinary system disorders is an urgent task. In the pharmaceutical market of Ukraine, there are medicinal products of plant origin that exhibit antispasmodic, antiseptic, anti-inflammatory, diuretic effects, as well as dissolve concrements and eliminate them from urine. Aim of the work. To determine the optimal composition of antiadhesive components for the production of effervescent tablets with a thick extract of silver birch leaves. Materials and methods. During the experiment, the effects of macrogol 6000, macrogol 4000, glycine and fumaric acid on the technological characteristics of the model granulates and the resulting tablets were investigated. In the experiments, modern equipment and techniques were used to study tablets ejection force, granules fluidity, strength of tablets, disintegration of tablets. Results. Macrogols of 4000 and 6000 showed the best results in all studies. With satisfactory flow rates, they showed a high anti-adhesive ability and the resulting tablets had the highest rates of crushing resistance. Macrogol 4000 has the most optimal anti-adhesive properties, while the most intense reduction in the pressure of pushing tablets from the matrix is observed at its content under 4 %. Macrogol 6000 has satisfactory lubricating properties, but at a concentration of 6 %. Thus, based on the performed studies, it has been found that for the production of effervescent tablets with a thick extract of silver birch leaves it is advisable to use the macrogol 4000 (or macrogol 6000) as the antiadhesive component. Conclusions. Hydrophilic lubricants (macrogols 4000 and 6000, glycine, fumaric acid) were used to determine the optimal composition of anti-adhesive excipients to produce effervescent tablets with a thick extract of silver birch leaves, among which the best results for all were shown by macrogols 4000 and 6000. According to the results of the research, as the antiadhesive component for the preparation of tablets with thick extract of silver birch leaves, macrogol 4000 was selected which showed high antiadhesive ability and the obtained tablets had the highest indices for resistance to crushing, while the most intense reduction of the pressure of pushing out tablets from the matrix was observed at macrogol 4000 concentration up to 4 % in tablet mass

    A process of creating a static neural network intended for diagnosing bypass gas turbine aircraft engines by a method of cat- egorizing the technical state of the engine flow path was considered. Diagnostics depth was β€œto the structural assembly”. A variant of diagnosing single faults of the flow path was considered. The following tasks were set: β€’ select the best neuron activation functions in the network layers; β€’ determine the number of layers; β€’ determine the optimal number of neurons in layers; β€’ determine the optimal size of the training set. The problem was solved taking into account the influence of parameter measurement errors. The method of structure optimization implies training the network of the selected configuration using a training data set. The training was periodically interrupted to analyze the results of the network operation according to the criterion characterizing the quality of classification of the engine technical state. The assessment was performed with training and control sets. The network that pro- vides the best value of the classification quality parameter assessed by the test set was selected as the final network. The PS-90A turbojet engine was selected as the object of diag- nostics. Diagnostics was carried out on takeoff mode and during the initial climb. Primary optimization was carried out according to the data with no measurement errors. It was shown that a two-layer net- work with the use of neurons having a hyperbolic tangent function in both layers is sufficient to solve the problem. The size of the first network layer was finally optimized according to the data contain- ing measurement errors. A two-layer network with eight neurons in the first layer was obtained. The share of erroneous diagnoses measured 14.5 %

    Introduction. Diabetes mellitus type 2 (DM 2) is a metabolic disease, which is characterized by chronic hyperglycemia. It develops as a result of insulin secretion disorder or mechanisms of its interaction with tissue cells. It is known that hyperglycemia is the main cause of cardiovascular complications development.The aim of the work – to study the effect of dry extracts from stevia and bilberry leaves on the metabolic disorders development in rats with experimental diabetes mellitus, caused by dexamethozone on a high-fructose diet ground.Methods of the research. The concentration of glycosylated hemoglobin, the level of fructosamine, the area under the glycemic curves, the level of immunoreactive insulin have been determined in the serum. Lipoperoxidation indicators have been determined according to diene conjugates (DC) and TBA-reactive products (TBA-RAP) content, the state of the antioxidant system has been assessed by reduced glutathione concentration determining (GSH) [8]. The significance of intergroup differences have been assessed due to Student's t-criterion.Results and discussion The introduction of low-dose dexamethasone in laboratory animals causes a complex of disorders, which are specific for metabolic syndrome and type 2 diabetes. Thus, a rise in the level of glycosylated hemoglobin, a concentration of fructosamine, a glucose level, a basal glycemia level, an increase in the area under the glycemic curves are observed in the serum of rats under the indicated conditions. With the introduction of dry extracts of stevia and bilberry leaves together with dexamethasone, the normalizing influence of these substances on the investigated indicators is observed.Conclusions. The use of dry extracts from stevia and bilberry leaves has a normalizing effect on glycosylation indicators, glucose level and lipid metabolism in the rats’ serum in type 2 diabetes mellitus. The more pronounced antioxidant effect of the extract from bilberry leaves and the hypoglycemic action of the extract from stevia leaves have been shown. This proves the advisability of the extracts from stevia and bilberry leaves joint application with the aim of drugs creation on their basis for metabolic disorders correction.ВступлСниС.

    We have studied the chemical composition and antibacterial profile of ethanolic extract of Punica granatum L. (Lythraceae) on strains of microorganisms in vitro. Analysis using GC-MS showed 5-hydroxymethylfurfural (36.6%), D-sucrose (23.2%), sorbitol (6.7%), palmitic acid Ξ²-monoglyceride (5.6%), 2-furancarboxaldehyde (3.5%) and Ξ²-D-glucopyranose (3.3%) as the major components of the title extract. The experiment revealed a positive antibacterial effect of extracts obtained from P. granatum on 14 strains specifically Enterobacteriaceae microorganisms (Escherichia coli, Enterobacter aegorenΠ΅s, Proteus vulgaris, Serratia marcescens, Klebsiella pneumonia), Listeriaceae (Listeria ivanovi, L. Ρ–nnocua, L. monocytogenes) and yeasts from the family Saccharomycetaceae (Candida albicans). Our study showed that in many cases these extracts more intensively affect multi-resistant strains of microorganisms than macrolide antibiotic azithromycin and is therefore a source of molecules to be exploited in medicine or by the pharmaceutical industry. The investigated extracts of P. granatum can be recommended for further in-depth research against poly-resistant strains of the above-mentioned microorganisms. Effective drugs perform a leading role in providing stable veterinary well-being of livestock and healthcare of the population. The present study showed that the studied plant species more intensively affects multi-resistant strains of microorganisms than sodium salt of azithromycin. Lethal concentration (LC50) of ethanol extract from pomegranate for Paramecium caudatum Ehr. equaled 0.3%. Death of 100% of nematode larvae of Strongyloides papillosus (Ihle) was recorded during 24 h exposition in 20% extract of P. granatum peel
