[Cow colostrum: component composition, biological properties and application practice].

Bovine colostrum (ВС) has a high biological value, which allows it to be used for the development of new functional products. The aim of the study was to assess the possibility of using BC for the prevention and treatment of infectious and non-infectious diseases. Material and methods. The search for scientific information on the study of the component composition, immunobiological properties and the use of BC in clinical practice was carried out using the databases of the RSCI, CyberLeninka, ScienceDirect, PubMed. Results. The macro- and micronutrient composition of BC is presented, its changes over time from the moment of calving are described. A comparative analysis of the content of various components in milk and colostrum is presented. A detailed list of antimicrobial factors that increase nonspecific resistance and provide immunocorrective, antimicrobial and anti-inflammatory effects is submitted. The possibility of using BC in clinical practice as a part of complex therapy in the treatment of various infectious diseases, including severe acute respiratory syndrome caused by the new coronavirus infe ction SARS-CoV-2, as well as in cardiovascular diseases, allergies, autoimmune and oncological diseases, has been demonstrated. Conclusion. According to the literature, BC has a high safety profile and is applicable to all age groups of the population. Given the wide range of biological activity of BC components, a promising area of scientific research is the development of the products for therapeutic and prophylactic purposes, including dietary supplements, based on its ingredients, which have the desired properties for correcting the immune status, preventing non-communicable and infectious diseases, as well as for prevention of occupational diseases among persons working in harmful working conditions.

[Radiative and hygienic certification in Armed Forces, problems of its implementation and ways of perfection].

Radiative and hygienic passportization is one of the most actual pattern of socio and hygienic monitoring in Armed Forces. Radiative and hygienic passport is the main document which characterizes the safety control in military unit and uses the sources of ionizing radiation. Sanitary and epidemiologic institutions were imputed to control the formation of radiative and hygienic passports, analysis and generalization of its data, formation of conclusions about the condition of radiation security in the military units. According to radiative and hygienic passportization, which took place in 2009, the radiation security in the Armed Forces and organizations is satisfactory, but there are some problems of providing of radiation security of personnel under the professional and medical radiation. The salvation of its problems requires the effective work of official functionary of radiac object and institutions of state sanitary and epidemiological supervision in Armed Forces of Russian Federation.
