DIAGNOSTIC AND CLINICAL ASPECTS OF NORMOCALCEMIC PARATHYROID HYPERPLASIA AND NON-RENAL SECONDARY HYPERPARATHYROIDISM IN EXPOSED AND NON;EXPOSED TO IONIZING RADIATION INDIVIDUALS (LITERATURE REVIEW AND OWN RESEARCH DATA).

Parathyroids are the key regulators of calcium-phosphorus metabolism. By means of parathyroid hormone they respond to any changes in the serum level of calcium and phosphorus ions and determine the integrity of skeleton, affecting almost all systems and cells where calcium and phosphorus are involved in metabolism and/or signaling.Disorders of parathyroid function are associated with significant complications accompanying secondary hyperparathyroidism.

Serum content of total adipionectin in the ChNPP accident clean up workers of the «iodine period» suffering from type 2 diabetes mellitus (literature review and research data).

Objective: assay of the total adiponectin level in the ChNPP accident clean up workers (ACUW) of the «iodine peri od» exposed to ionizing radiation in a young age and suffering now from type 2 diabetes mellitusMaterials and methods. The Chernobyl Nuclear Power Plant accident clean up workers (ACUW) of the iodine period (n=111) exposed to ionizing radiation at a young age (18-35 years) were examined in two groups: Group I (main study group, n=66) of persons with type 2 diabetes mellitus (DM) and Group II (comparison group, n=45) of persons with normal glucose challenge test results. Total radiation doses varied in the range of 10.

Peculiarity of prooxidant-antioxidant balance indicators in patients with nonalcoholic fatty liver disease who have been exposed to ionizing radiation due to the Chornobyl NPP accident.

Objective: To define the features of prooxidant antioxidant balance in patients with nonalcoholic fatty liver disease who have been exposed to radiation as a result of the Chornobyl accident.

Methods: using Indicators characterizing the processes of oxidative modification of macromolecules by blood lev els of compounds with isolated double bonds (CIDB), diene conjugates (DC) oxodiene conjugates (ODC), secondary products of lipid peroxiodation reacting with thiobarbituric acid, products of oxidative modification of proteins in blood serum by levels of neutral and basic 2,4 dynitrofenilhidrazones, superoxide dismutase and catalase content in erythrocytes and ceruloplasmin in plasma were determined for the diagnosis of oxidative stress. The factor of antiox idant state was calculated.

Expression of Cyclin d1 protein and CCND1 та PNKP genes in peripheral blood mononuclear cells in clean up worker of Chornobyl accident with different state of immune system.

Objective: to investigate the Cyclin D1+ cells levels changes, associated CCND1 and PNKP genes in peripheral blood mononuclear cells in clean up workers of Chornobyl accident with different state of immune system in depends on the dose irradiation.

Material And Methods: Relative level of Cyclin D1+cells in peripheral blood mononuclears of 39 clean up workers, men, irradiated in dose range (0,01-2,00) Gy have been analyzed. Immunological status of examinee' subjects was determined by CD3/19, CD4/8, CD3/HLA DR, СD3/16/56 testing using flow cytometry method and Ig A,M,G testing by immunoenzymatic assay in blood.

[Assessment of functional activity of phagocytic system in patients suffered from Dupuytren's contracture with hepatic fibrosis].

Dupuytren's contracture--a pathology that should not be seen as an isolated lesion tendon-aponeurotic structures of the palmar surface of the hand, but as a disease that requires careful research and a comprehensive, differentiated approach to treatment.
