The spread of a new strain of SARS-CoV-2 and the pandemic that caused it has led to huge changes around the world. So, it reminded us again about the importance of developing measures for the prevention of infections that transmitted by air droplets. \u0000Aim: investigation of the antimicrobial activity of aminomethanesulfonic acid (AMSA) and its derivatives (N-(2-hydroxyethyl)-(HEAMSA), N-benzyl-(BnAMSA) and N-(tert-butyl)-(t-BuAMSA)) which impregnated on filtering fibrous material and can be used for the manufacture of anti-aerosol elements of individual respiratory protection against strains of Staphylococcus aureus with different level of antibiotics resistance. \u0000Materials and methods. The standard method of Kirby and Bauer disks is used for the investigation of the specific activity of antimicrobial drugs. The 24-hour cultures of microorganisms that contained (1.2+0.2)x109 CFU/ml were diluted according to the turbidity standard. The results were detected after 18-20 hours of incubation at 37°C. The 0.5 cm diameter filter fibrous discs contained the following compounds: AMSA, HEAMSA, BzAMSA, t-BuAMSA and streptocide (sulfanilamide) as a reference with active compound content (Q) at a final concentration of 0.047 and 0.236 mmol/g. \u0000Results. All test samples with aminomethanesulfonic acids at a final concentration of 0.236 mmol/g that were applied to the filter fibrous material had a higher level of inhibition of the growth of the microorganisms than the prototype using streptocide (sulfanilamide) e against the strains of Staphylococcus aureus 2781 and Staphylococcus aureus Kunda. \u0000Conclusions. Samples based on HEAMSA showed the greatest antimicrobial activity against the studied strains of Staphylococcus aureus from all research samples of filter fibrous material with YAMSA. They were characterized by the maximum hydrophilicity and the minimum value of the empirical pKa function lgPow. AMSA and HEAMSA were characterized by the smallest particle sizes on the surface of lavsan fiber according to electron microscopy analysis.

Dental caries is a widespread worldwide disease of multifactorial genesis. The leading mechanism of its development is a long-term imbalance of the physiological balance between the inorganic component of the teeth hard tissues and the liquid biofilm formed on their surface, the predominance of the demineralization processes in hard tissues over the processes of remineralization. The use of dental enamel sealants has proven to be effective in preventing and reducing the intensity of dental caries. Modern bioactive polymer sealants for enamel contain such remineralizing agents as sodium fluoride, nanoamorphous calcium phosphate, beta-tricalcium phosphate, and particles of bioactive glass. For all dental composite filling materials, mechanical stability is one of the prerequisites for the long-term clinical success of restorations and fillings, and accordingly, temporary protective structures made of sealants. \u0000Aim: to compare the flexural strength and modulus of elasticity of three modern photocomposite enamel sealants. \u0000Materials and methods. In laboratory conditions for three modern photocomposite dental materials for sealing fissures and pits of enamel \"Fissurit FX\" (VOCO), \"Clinpro™ Sealant\" (3M™ ESPE™) and \"Jen-Fissufil\" (Jendental-Ukraine LLC) a flexural strength (three-point test) and elastic modulus were determined in accordance with the requirements of the international standard ISO 4049:2019. 6 samples of each material, polymerized and kept for a day in humid conditions, were examined. \u0000Results.

In the structure of purulent complications, peritonitis, destructive lesions of abdominal organs, and, as a rule, advanced forms of these diseases occupy one of the first places - 15-25% of urgent surgical diseases are complicated by peritonitis. It is generally known that the leading role in the triggering mechanism of the development of peritonitis belongs to the systemic inflammatory reaction, a component of which is phagocytosis, cellular and humoral immunity. However, the results of research on the state of functional activity of the endothelium in experimental peritonitis are limited. \u0000Aim: to study the activity of NO-synthase, FV and endothelin-1 in rats with experimental peritonitis. \u0000Materials and methods. Experimental studies were conducted on 24 non-linear laboratory rats, which were divided into 2 groups: 1 group – intact control (animals received distilled water), 2 group – animals of the control pathology group. According to the \"Methodological recommendations for preclinical study of medicinal products\", experimental peritonitis was studied on the model of V. A. Lazarenko. Indicators of vascular-platelet and coagulation hemostasis were determined according to generally accepted methods. Indicators characterizing endothelial dysfunction were studied according to generally accepted methods. \u0000Results. The most likely mechanism that is damaged in the endothelium during peritonitis is the activation of the synthesis of inducible NO-synthase by neutrophils/macrophages in response to infection. It is possible that the hyperproduction of nitric oxide, on the one hand, is aimed at destroying microflora and oxidizing toxins, and on the other hand, at suppressing the expression of tissue factor and cell adhesion molecules. platelet aggregation and cascade disorders in the hemostasis system. In animals with experimental peritonitis against the background of oxidative stress, there was an increase in the number of circulating desquamated endothelial cells in the blood, which is a highly specific marker of endothelial dysfunction. The level of the Willebrand factor also increased, which indicates the pathogenetic dependence of the factors that damage the endothelium of the vascular wall on the concentration of the Willebrand factor, which helps to reduce the permeability of blood vessels by adhesion of platelets to the endothelium. Confirmation of the development of endothelial dysfunction in peritonitis is an increase in the concentration of endothelin-1, which is a regulator of the process of vascular neoangiogenesis in response to endothelial damage. \u0000Conclusion. Hyperproduction of nitric oxide not only reflects the processes that occur in the focus of vascular endothelium damage, but also affects the severity of the inflammatory process and the consequences of the disease.","PeriodicalId":52737,"journal":{"name":"Medichna nauka Ukrayini","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48354896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zokrema, in a group of animals with a modeled ischemic stroke, the latent period of entry to the dark chamber of growth (p<0.05), as well as in the eyes with comorbid pathology (p<0.05) was compared with the intact group. \u0000There was a decrease in the hour of perebuvannya in clarified sleeves, as well as the number of clarified sleeves in both experimental groups of creatures. \u0000Conclusion. Significant changes in psychophysiological tests were noted for the minds of an ischemic stroke, however, in animals with a modeled comorbid pathology, there were more manifestations of changes in all indications, which indicated a strengthening of the anxiety of that change. Obtained results require the destruction of pathophysiological mechanisms of depressive-anxious disorders on aphids of cerebrovascular changes.","PeriodicalId":52737,"journal":{"name":"Medichna nauka Ukrayini","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46838521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The article is devoted to an analytical review of the methods of using stem cells in the treatment of diabetes mellitus (DM). \u0000Aim: to analyze, based on the data of the literature, the prospects of using stem cells for the treatment of DM. \u0000Materials and methods. Review of scientific literature in the international electronic scientometric databases PubMed, Scopus, Web of Science by keywords for the period 20017-2023. The search was carried out by three independent authors. 98 sources were selected for analysis, of which 33 were used that met the search criteria. \u0000Results. DM is a serious problem for the health care system worldwide, which requires the development of new innovative and effective therapeutic approaches. The use of stem cells is one such promising strategy for solving this problem. The ability of stem cells to differentiate into various body cells, including beta cells of the pancreas, was analyzed. Animal studies have demonstrated the ability to improve insulin synthesis and lower blood glucose levels. The use of stem cells in the treatment of DM is not a widespread approach and requires additional clinical studies. General information on the use of stem cells in the treatment of diabetes is presented and the prospects of this method of therapy are outlined. \u0000Conclusions. The use of stem cells in the treatment of diabetes is a promising technology that may open new opportunities for the treatment of this disease. However, more research needs to be done, a number of technical, ethical, and legal issues need to be addressed, as well as regulatory standards for the production and use of stem cells.","PeriodicalId":52737,"journal":{"name":"Medichna nauka Ukrayini","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43237073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
