CORRECTION CRITERIA FOR THE BONE TISSUE STRUCTURE DISORDERS IN CHILDREN LIVING IN RADIOLOGICALLY CONTAMINATED TERRITORIES AFTER THE CHORNOBYL NPP ACCIDENT.

Objective: To determine the structure of abnormalities of bone tissue and substantiate the management tactics inacute lymphoblastic leukemia (ALL) pediatric patients and in children with no oncohematological disorders, livingin radiologically contaminated territories (RCT).

Materials And Methods: Children (n = 220) living in RCT were the study participants i.e.

DRIVERS OF HYPERFERREMIA IN CHILDREN LIVING ON RADIOLOGICALLY CONTAMINATED TERRITORIES AFTER THE CHNPP ACCIDENT IN UKRAINE.

Objective: assessment of clinical-hematological and metabolic-biochemical parameters of the of bone tissue and hormonal regulation depending on the serum iron content and radiation dose values in children living on radiologically contaminated territories after the ChNPP accident in Ukraine.

Materials And Methods: Children (n = 271) living on radiologically contaminated territories (RCT) of Ukraine were involved in the study. Three study groups were formed according to the serum iron level (SIL), namely group I with SIL 10.

FACTORS AFFECTING MECHANISMS OF INCREASED BONE DENSITY FORMATION IN CHILDREN LIVING ON RADIOLOGICALLY CONTAMINATED TERRITORIES AFTER THE ChNPP ACCIDENT.

Objective: to determine the causes of increased bone mineral density (BMD) based on case history, clinical and laboratory data, including the assay of hormones involved in ossification processes in children, living on radiologically contaminated territories (RCT) after the accident at the ChNPP, compared to the normative BMD patterns.

Materials And Methods: There were 289 children involved in the study. The 1st group included persons with a BMD above 100 IU, 2nd group - with normative BMD (100-85 IU).

THYROID DISEASE IN THE LATE OBSERVATION PERIOD UPON CHEMO AND RADIOTHERAPY IN CHILDREN/SURVIVORS OF ACUTE LYMPHOBLASTIC LEUKEMIA.

Objective: to assess the thyroid disease in the late observation period in children who had received chemo- andradiotherapy for the acute lymphoblastic leukemia (ALL) taking into account gender, age period and disease sub-type.

Materials And Methods: The incidence and nature of thyroid disease (hypothyroidism, thyroiditis, and thyroid can-cer) were studied in children-survivors of acute lymphoblastic leukemia (ALL) being in remission from 6 to 25 years.The distribution of patients by leukemia subtypes was as follows: «common» - 67.

ASSESSMENT OF QUALITATIVE CHANGES IN PERIPHERAL BLOOD CELLS IN CHILDREN - RESIDENTS OF RADIOLOGICALLY CONTAMINATED TERRITORIES IN THE LATE PERIOD AFTER THE ChNPP ACCIDENT.

Objective: to establish the relationship between quantitative and qualitative parameters of peripheral blood cells(lymphocytes, neutrophilic granulocytes, monocytes, platelets) depending on the type of somatic diseases andannual internal radiation doses from 137Cs in children - residents of radiologically contaminated territories in thelate period after the Chornobyl Nuclear Power Plant (ChNPP) accident.

Materials And Methods: There were 175 children included in the study comprising residents of radiologically con-taminated territories (n = 79) aged from 4 to 18 years. Annual internal radiation doses in children from 137Cs rangedfrom 0.

MORBIDITY OF THE CIRCULATORY SYSTEM DISEASES OF RESIDENTS FROM RADIOACTIVELY CONTAMINATED AREAS. ANALYSIS OF THE EFFECT OF CHRONIC LOW/DOSE IONIZING RADIATION.

Objective: to study post-accident levels of illnesses system diseases of residents from radioactively contaminatedareas aged 0-60 years on the date of the Chornobyl accident, and to analyze the effect of chronic low-dose ionizingradiation.

Materials And Methods: Epidemiological research and analysis of morbidity of circulatory system diseases of resi-dents of radioactively contaminated areas (RCA) has been carried out. The individuals who were studied includedRCA residents aged 0-60 (98, 902 persons) on the date of the Chornobyl accident.

Psychosocial state of the adult evacuees and risk factors of negative change.

Unlabelled: Numerous scientific studies have been carried out since the ChNPP accident indicating that the last one has caused a severe psychosocial stress in survivors. Population of radioactively contaminated territories, people migrated from the areas of strict radiation control, and accident consequences clean up participants in 1986 1987 were covered by the conducted research projects. Nature of the stress herewith is polygenic and includes factors directly related to the Chernobyl catastrophe, and factors being a result of social and economic circumstances.

Social and psychological state of the Chornobyl clean up workers. Risk factors for negative changes.

Unlabelled: It is generally recognized that the Chornobyl nuclear accident caused strong psychosocial stress affecting the entire population of Ukraine, primarily people involved in recovery operations. But what are the reasons? What is the struc ture of stressors? What are their social, medical and biological consequences, what are strategy and preventive meas ures? Issues that require special research and development.

Objective: To study social and psychological state of the Chornobyl cleanup workers 1986-1987, and to determine regularities of changes and dangerous risk factors.
