LEVELS AND RELATIVE RISKS OF MORTALITY OF CHORNOBYL CLEAN-UP WORKERS IN 1986-1987 YEARS FROM MAIN NON-NEOPLASTIC DISEASES (OBSERVATION PERIOD 1988-2021).

Unlabelled: The emergency destruction of the 4th reactor of the Chornobyl nuclear power plant necessitated large-scale emergency work, which involved large contingents of specialists. Analysis the mortality of Chornobyl clean-up workers isan important and relevant basis for planning medical protection measures in conditions of a potential threat ofemergency and other radiation situations.The objective of this work is to determine the levels and relative risks of mortality of Chornobyl clean-up workers in1986-1987 years from major non-tumor diseases depending on the received dose of radiation exposure, taking intoaccount age and time after the accident (period of epidemiological studies 1988-2021).

Distribution and appearance of myosin, dystrophin, and collagen IV in strabismus-affected extraocular muscle tissue compared with control tissue.

Objective: Extraocular muscles have complex development processes. The present study aimed to analyze the presence of myosin, dystrophin, and collagen IV in the strabismus-affected extraocular muscle.

Methods: This research was an observational case-control study.

BRAIN AND EYE AS POTENTIAL TARGETS FOR IONIZING RADIATION IMPACT. PART V - ORGANIC AND FUNCTIONAL CHANGES CORRELATION ON THE EXAMPLE OF CERTAIN DISEASES.

The question about correlation between organic and functional changes in persons, exposed to radiation is still insufficiently studied. Dynamics of morbidity for different forms and classes of non-tumour diseases periodisation, proposed by epidemiologists, suggests the identification of three main periods: «early» (the first 6 post-Chornobyl accident years); «distant» (12-21 years) and «late» (22-30 years). However, the correspondence this periodisation to the results of epidemiological data, without taking into account the clinical features of the diseases, may contribute to the impression, that in the first period after a radiation disaster functional disorders (or autonomic regulation disorders, etc.

PREVALENCE OF AGE-MACULAR DEGENERATION IN PERSONS OF WORKING AGE WHO APPLIED TO PARTICIPATE IN WORK IN ACTION CONDITIONS IONIZING RADIATION: PRELIMINARY RESULTS.

Unlabelled: In recent decades, several large-scale epidemiological surveys of the eyes have been conducted to determine the global prevalence of retinal degenerative diseases (for example, the Blue Mountains Eye Study). The results of such studies were evaluated several decades, and the studies themselves required significant material resources. Such large-scale projects have not been carried out in Ukraine.

RETINA VESSELS CHANGES IN CHORNOBYL NUCLEAR POWER PLANT EMPLOYEES WHO EXPERIENCED LONG-TERM ABNORMAL RADIATION EXPOSURE AT THE WORKPLACE AS A RESULT OF THE OCCUPATION OF CHORNOBYL NUCLEAR POWER PLANT IN 2022.

Unlabelled: During the occupation of the Chornobyl Nuclear Power Plant (ChNPP) in 2022, a group of employees remained in the working town for a long time. These personnel were exposed to long-term radiation and non-radiation factors of the production environment, as well as stress and other factors. These factors could result in negative changes of health.
