Basic scientific and practical results of the study of possibility of obtaining alternative binders from production wastes to fill man-made voids at underground ore mining are presented. The objective of the study was to determine the technological possibility and economic feasibility of using available low-active substances as substitutes for expensive and scarce cement. It was shown that it is possible to obtain a binder from dolomite wastes, equivalent in properties to cement, which makes it possible to meet the demands of environmentally correct ore mining technologies. It has been established that hardening mixtures based on dolomites and enrichment tailings are only 8-22% inferior in strength to mixtures with standard cement and are suitable without restrictions for the construction of nature protection massifs in mine workings. Recommended activation of wastes increases the strength of the hardening filling mixture by 15-20% in comparison with the basic technology. With additional preparation in activators, a fundamental change in the quality of dolomite products is possible. The use of wastes in the production of a hardening mixture will free up the land occupied by storage facilities and organize the production of competitive products. Alternative binders and inert materials are recommended for use.

he modern interpretation of the principles of therapy of periodontal pathology brings individualized treatment of patients to the first place. The basic principle of local therapy of periodontal diseases, in our opinion, is drug therapeutic treatment. The success of the treatment of periodontal diseases, the duration of remission and the prevention of complications largely depends on the quality of the impact on the oral cavity microflora. Recently, antiseptics of complex action have been successfully used. One of the representatives of the group of antiseptics is the drug «Citeal», which contains active substances: hexamidine, chorhexidine, chlorcresol. The purpose of the work is to increase the effectiveness of treatment of patients with periodontal pathology due to the use of three-component antiseptic agent of complex action — «Citeal». The results of a comprehensive examination of patients after the end of treatment show an improvement in oral hygiene, a decrease in the PMA index in comparison with the data before treatment. The Schiller-Pisarev test also became negative after the treatment. It is recommended to carry out professional hygiene with the use of antiseptic solution «Citeal» in a 1:10 dilution in the form of application to the marginal and alveolar part of the gums and irrigation of periodontal pockets, followed by mandatory rinsing of the mouth with water to remove residues. It was found that an individualized and differentiated approach to the treatment of patients with various forms of gingivitis and generalized periodontitis, who have orthopedic structures, prevents exacerbation of the disease during the year.

Background. The deficiency of essential nutrients in the human body is the root cause of reduced efficiency, general resistance of the body to various diseases. That is an urgent problem in the context of the spread of coronavirus infection. In this regard, the search for opportunities to meet the needs of the population in food products that contain biologically active substances (BAS) through the use of high-value and at the same time available plant raw materials is extremely important. Marigolds attract special attention among such raw materials. The aim of the work is to study the chemical composition and evaluate the consumer properties of Tagetes L. varieties, zoned in the Kiev region, to prove the possibility of increasing the biological value of pasta by adding to their recipe powder from marigold inflorescences. Materials and methods. The object of research is pasta of B group (noodles). Inflorescences of marigolds of different varieties gathered during the flowering period in July-September 2019–2020 in the territory of Vasylkiv and Obukhiv districts of Kyiv region, Ukraine were used as enriching plant raw materials. The quality of finished pasta was assessed by organoleptic and physicochemical indexes (moisture content and titratable acidity). The content of mineral elements in the fine powder of marigold inflorescences was determined on the EXHERT-3L device, the quantitative composition and BAS identification – by spectrophotometric analysis on the device Specord-200 Analytic Jena UV-vis. The integrated quality index of pasta products was calculated taking into account the importance factors of individual indexes. Results. Comparing the obtained results, we can state that all the studied varieties – Gold Kopfen, Orange Flame, Hawaii, Equinox are characterized by high biological value, regardless of the area of collection. As a result of calculated and experimental studies it was determined that the addition of 7 % of the supplement does not provide the required supply of vitamins and minerals. Replacing the flour in the recipe by 20 % significantly improves the mineral composition, but deteriorates the taste and aromatic properties of pasta. The most optimal and rational amount of added additive is 15 %, as it improves the organoleptic properties of pasta and enriches their BAS. Conclusion. The usage of non-traditional vegetable raw materials, in particular powder from marigold inflorescences, which is rich in biologically active substances, allows not only to expand the range, improve the quality of finished products, but also increase the biological value of the product. The optimal amount of additive –powder from marigold inflorescences, was defined. It is 15 % by weight of flour in the production of noodles. This concentration allows not only to improve the organoleptic properties, but also to increase the content of biologically active substances – vitamins, micro- and macronutrients. The usage of non-traditional natural raw materials (powder from marigold inflorescences) allows to abandon artificial colorsand give the finished pasta a pleasant colorand aroma.

Production of environmentally friendly cucumber products is one of the important problems of modern vegetable growing. In the current situation, many issues of cucumber technology using the low-volume technology method require adjustment and further improvement. The purpose of the research was to study and assess the effect of combinations of zircon with biofertilizers against the background of the use of biological products on the growth, development, yield and quality of cucumber. The complex treatment of cucumber plants of the F1 Atlet hybrid with biologically active substances (BAS) contributed to an increase in biometric indicators in comparison with the control throughout the entire crop rotation. The period from germination to the beginning of flowering and fruiting decreased, the plant height increased by 7.2–13.2% and the stem diameter by 12.5–17.5%. The yield was significantly influenced by the growth of the leaf area of cucumber plants, which increased in variants with experimental technologies by 5.9–34%. Under the influence of the studied factors, the yield of standard cucumber production increased by 8.0–27.6%. The mass fraction of fruits that do not meet the requirements of the standard was 6.6–8.1%. On the control variant, the output of non-standard products increased to 10%. The highest net income and level of profitability were obtained with the combined use of Zircon with Ecofus, both against the background of the use of biological products (659.3 rubles / m2 or 38.4%) and without them (685.13 rubles / m2 or 40.1%).

Today, glaucoma is considered to be the most common cause of irreversible blindness. The treatment of this disease is aimed at reducing intraocular tension in order to slow down the deterioration of visual functions and to maintain accept‑ able quality of life. Most ophthalmologists prefer local medicamentous therapy. Despite a significant expansion of the range of antihypertensive medicines, a significant increase in the hypotensive effect is not always achieved in each certain case, at the same time, at long-term (sometimes lifetime) treatment local and systemic adverse reactions arise and intensify. The findings of recent clinical trials presented in this overview demonstrate an adverse effect of active compounds, preservatives and ad‑ ditives of ophthalmic medicines not only on the eye surface but also on the structure of anterior and posterior eye segments. Taking into account possible side effects of each component of medicines used in glaucoma therapy, ophthalmologists will be able to reasonably approach the choice of optimal treatment regimens with the lowest risk for patients.
