Introduction. Hypovitaminosis is currently common among various social groups. The present research offers a new medical formulation that includes a complex of antioxidant vitamins with a highly beneficial synergistic effect. Study objects and methods. The research employed the SF-36 questionnaire to assess the quality of life in patients with chronic diseases, as recommended by the WHO. The SF-36 questionnaire provides a quantitative description of the physical, emotional, and social components of the quality of life. Clinical control was performed on days 31–32 from the onset of the medication. The state of the microcirculatory bed was assessed in laboratory conditions by applying pressure to the nail bed. The concentration of malondialdehyde was determined by the method developed by M. Uchiyama and M. Mihara. Results and discussion. The paper introduces the formulation and describes the properties of each component. The efficacy of the medicine was confirmed experimentally. Twenty education and health workers were administered the medicine for one month. The control group consisted of fifteen volunteers, who were randomized and grouped according to professional factor, sex, and age. The control group consumed the medicine together with standard vitamins A, C, and E in adequate dosages. Conclusion. The developed medicine proved able to improve the physical, social, and emotional aspects of life quality under high psychophysical stress. The polyvalent effect of the components demonstrated a tropism to collagen synthesis. In addition, it showed an antioxidant effect and improved microcirculation. The medicine can be used preventively to reduce the risk of chronic pathology based on the accumulation of excess free radical activity.
The increasing volume of consumption of probiotics and functional food products requires determination of standardized criteria for cultures and their exometabolites used in functional products manufacturing. The study was aimed at developing criteria for the estimation and standardization of exometabolites and the colony-forming ability of probiotic strains for functional food production. The work included such microbiological and physicochemical methods as GC-MS, GPC, UV, and FT-IR-spectroscopy. Based on the results of the study, the comparative analysis of the microbiological properties of probiotic Bifidobacterium strains was provided, the fatty acid composition of the cell wall was described, and the physical and chemical study of the exopolymers produced by them was carried out. According to the data of FT-IR- spectroscopy, the characteristic features of the components of the cell wall of Bifidobacterium strains were established. Bifidobacteria form the unique composition of organophosphorus structures of lipoteichoic acids, which determines the adhesive ability of strains. The authors studied the molecular weight distribution of the samples of exometabolites isolated from the nutrient medium after the cultivation of bifidobacteria, under conditions of gel-permeation chromatography. The spectral (UV, FT-IR) characteristics of the produced metabolites and their chromatographic fractions were compared. The fatty acids of the Bifidobacterium cell membrane were analyzed using the GC/MS method. The fatty acids were extracted from bacterial cells with different hydrophobicity with a mixture of chloroform and hexane. It has been established that the hydrophobicity is determined by different contents of unsaturated and branched fatty acids in the bacterial membrane. Hydrophobic bifidobacteria are the only that contain the isopentadecane (isoC15:0) and methyl-tetradecanoic (13Me-C14:0) acids. With the mean hydrophobicity, a high content of the isopalmitic (isoC16:0) and stearic (C18:0) acids was established. Low-hydrophobic strains are characterized by a low content of monounsaturated fatty acids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
