THE EXPERTISE OF THE CAUSAL RELATIONSHIP BETWEEN THE DEVELOPMENT OF ARTERIAL HYPERTENSION WITH PARTICIPATION IN WORKS FOR LIQUIDATION OF THE CONSEQUENCES OF CHORNOBYL NPP ACCIDENT IN REMOTE POSTACCIDENTAL PERIOD.

Unlabelled: Loss of health and work ability, as well as deaths from diseases of the circulatory system (DCS), first of all arterialhypertension (AH), due to radiation exposure (RE) in the conditions of Chernobyl catastrophe (ChC) in the performance of professional, military or official duties and / or living on radiation-contaminated areas, additional exposurenot through their own fault but due to a radiation accident, caused the development of a special form of medicalexpertise as part of the of medical social protection system for these suffered contingents.

Objective: to optimize decision-making criteria for the expert estimation of the casual relationship between development and progression of AH under the influence of RE in clean-up workers of the Chornobyl NPP accident (CWs)in the remote postaccidental period based on the study of odds ratio (OR) of the course of the disease.

Material And Methods: A retrospective analysis of the structure of 16073 cases of victims of the Chornobyl NPP(ChNPP) accident, considered by the Central Interagency Expert Commission of Ministry of Health of Ukraine for diseases, reason of disability and death causal relationship to ChNPP accident (CIEC) during 2014-2016, allowed toform a group of 401 cases of CW with AH to determine the OR of the course of the disease.

Radiomodifying and antitoxic effect of natural polymineral substances on the viability of the cell line L929 under the combined exposure to ionizing radiation and ions of heavy metals.

Objective: to study the radiomodifying and antitoxic effect of natural polymineral substances on cell viability in vitro under the combined exposure to ionizing radiation and ions of heavy metals.

Materials And Methods: Research was performed on an inoculated proliferating culture of the L929 cell line. Water soluble salts of lead acetate, copper, nickel and chromium oxide were added to the cell line culture at concentra tions of 0.

Features of cellular effects under combined effects of nickel ions and ionizing radiation.

Unlabelled: Under current conditions the probability of simultaneous effects of radiation and chemical factors on biological objects increases, and that's why the issue of combined influence of factore different by their nature becomes progressively important. The objective was to study the cytotoxicity of nickel ions in a test-system of cell culture and to detect the cellular reactions under a combined impact of nickel ions and ionizing radiation.

Materials And Methods: Studies were performed on inoculated cell culture line L929.

Features of cellular effects of combined exposure to ionizing radiation and copper ions.

Unlabelled: The constant increase in the scale of the use of chemicals and ionizing radiation in various industries, medicine and science increases their impact on all environmental components. Therefore, the probability of simultaneous effects of radiation and chemical factors on biological objects is growing. In this regard the issue of combined exposure to different by virtue of the nature factors is becoming more and more challenging.
