[Genetic polymorphism of cytogenetic effects of radon bath therapy in the patients presenting with gonosteoarthritis of different etiology based at the Belokurikha health resort].

Background: Borrelia infection is known to develop as a result of the bites of the ixodid ticks while the extremely difficult working conditions and low temperatures contribute to the development of chronic gonosteoarthritis (CGA) associated with ixodid tick-borne borreliosis (ITB) in the residents of the northern part of Siberia.

Aim: The objective of the present study was to elucidate the frequency of occurrence of the synovial cells in the knee joints exhibiting the cytogenetic abnormalities with special reference to trisomy of chromosome 7 and the glutathione-S-transferase (GSTM1) gene polymorphism in the residents of the northern part of Siberia presenting with Lyme borreliosis (LB) whose genotype contains some alleles of the GSTM1 gene before and after the treatment of LB-associated CGA with the use of the radon bath therapy. The secondary objective was to compare the respective characteristics and the results of the treatment with those in the patients with post-traumatic gonosteoarthritis (PTGA) and to evaluate the influence of the above abnormalities on the severity of CGA.

[Age-related traits of cytogenetic abnormalities in synovial cells of knee-joint in residents of the North of Siberia with arthritis of different etiology depending on the GSTM1 gene polymorphism of glutathion-S-transferase.].

It was studied the frequency of cells with cytogenetic abnormalities in the synovial fluid cells of the knee joint in patients of different age groups suffering from chronic arthritis associated with Lyme borreliosis (CAALB) or post-traumatic arthritis (PTA), depending on the polymorphism of the GSTM1 gene of glutathione-S-transferase. The study included 135 residents of the north of the Tomsk and Tyumen regions, 68 of whom suffered from CAALB, and the rest of the 67 patients who made up the control group were diagnosed with PTA. The results of this study have demonstrated that there are significant age-related differences in the frequency of cytogenetic abnormalities of the synovial fluid cells of the knee joint between young and elderly patients of СAALB.

[The computer morphometry of synoviocytes: the diagnostic possibilities and importance for patients with post-traumatic osteoarthritis].

The article deals with the data of computer morphometric analysis ofsynovial cells in 27 patients 35-53 years old with knee joint posttraumatic osteoarthritis stage I-II according Kellgren and Lowrence classification. The proposed technique of image computer analysis made it possible to apply a large specter of cardio-metric studies of pathologic processes in synovia of patients with post-traumatic osteoarthritis. The study results favored the implementation in computer morphometry new indicators characterizing brightness and optical density of image and permitting to evaluate the degree of compactization and amount of DNA in cells nuclei.

[Therapeutic effect of mineral water of the Belokurikha spa resort on the level of antinuclear antibodies and chromosomal aberrations in synovial cells of patients with osteoarthrosis].

The objective of this study was chromosomal analysis and measurement of anti-nuclear antibody level in synovial cells of 28 patients aged between 35 and 50 years with knee joint osteoarthrosis before and after radon therapy at an equivalent doe of 280 mSv per treatment course. It was shown that the presence of osteoarthrosis was associated with a rise in the number of synoviocytes characterized by cytogenetic defects in the form of various chromosomal aberrations the frequency of which positively correlated with the number of anti-nuclear antibodies. Radon therapy brought about a decreases in the titers of antinuclear antibodies in synovial cells and the number of chromosomal aberrations in their nuclear apparatus.

[Rehabilitation of patients with post-traumatic coxarthrosis].

This paper reports the results of rehabilitative treatment of 102 patients with post-traumatic coxarthrosis. The data obtained during clinical and instrumental examination provided a basis for the development of a diagnostic algorithm that allows for objective verification of ethiopathogenesis of structural and functional disturbances in the supporting organ. An original approach is proposed based on distinguishing the principal clinical syndromes associated with post-traumatic coxarthrosis.
