Aim: The aim of this study was to investigate the frequency of polymorphic variants of genes CYP2E1 and GSTA1 in patients with pathology of the hepatobiliary system (PHS) and healthy individuals in the Republic of Bashkortostan, as well as an analysis of possible associations of genotypes of this gene with the development of PHS. Materials and methods: There were examined 81 patients with pathology of the hepatobiliary system. Was studied association analysis of polymorphic loci of genes CYP2E1 and GSTA1. Results: The study demonstrated that a marker of risk of developing the disease is AA genotype (OR = 2,09; 95% CI 1,07-4,10) polymorphic locus gene rs3957357 GSTA1.

In chemical manufacturing along with alimentary factors, workers are exposed to occupational hazards resulting in reduced antitoxic protective properties of the organism. The purpose of the present work was to develop a preventive method for reducing antitoxic functions of the body of healthy workers exposed to chemical factors. We have produced the drink containing carrot juice, honey, olive oil. The study involved 50 employees (the average age was 37.4±5.5 years) with experience of over 15 years. The main group (25 people) were workers with reduced antitoxic function who received the drink before each day's work shift for 10 days, the control group - workers with normal anti-toxic function, which did not take a drink. It was found that antioxidant drink intake by healthy employees of a chemical complex lead to the decrease of the level of molecules of average mass at λ=254 nm and at λ=280 nm by 15.1±7.2%, the activity of gammaglutamyl transferase - by 19.1%, alaninaminotransferase - by 44.1%, aspartataminotrans-ferase - by 34.7% (indicators of the syndrome of endogenous intoxication), the decrease of the content of malondialdehyde (as an indicator of an excessive accumulation of products of lipid peroxidation) - by 43.8%, while the activity of catalase, that indicates an increase in the antitoxic functions of the organism, increased by 37.5%.

Follow-up of patients with nickel carbonyl acute poisoning varying in severity revealed a pathologic trend--functional and organic disorders of nervous system with asthenic vegetative, asthenic organic dysfunctions, toxic encephalopathy, bronchopulmonary diseases (toxic bronchitis with subsequent pneumosclerosis), toxic myocardium dystrophy, hepatobiliary system affection--toxic hepatopathy.

The-174G alpha-->C polymorphism of the interleukin 6 (IL-6) gene promoter and the-308G alpha-->A polymorphism of the tumor necrosis factor alpha (TNF alpha) gene promoter were tested for association with multiple myeloma (MM) varying in severity. Of 69 patients, 19 had aggressive MM, 26 had benign MM, and 24 had unidentified MM. The control group (N = 102) matched the test group in age and sex composition. The two groups did not significantly differ in allele and genotype frequencies of the IL-6 and TNF alpha genes. Genotype CC, which determines low-level expression of IL-6, occurred at a frequency of 0.35 in patients with low-progressing MM and was absent from patients with aggressive MM. The TNF alpha gene showed no association with predisposition to MM or clinical variant of the disease. On this evidence, the polymorphic variants of the cytokine genes were assumed to have no effect on predisposition to MM. As for MM progression, genotype CC of the IL-6 gene was associated with milder clinical signs in patients from Bashkortostan.
