RESUMO
We investigated the association of gene IL6 G(-174)C polymorphism and gene IL10 G(-1082)A polymorphism with coronary artery disease (CAD) in the Russian population. A total of 1145 patients with CAD diagnose on the basis of clinical studies in cardiological hospitals of Moscow, St -Petersburg, Kazan, Chelyabinsk, Perm, Stavropol and Rostov-on-Don. Supervision term was 9.10 +/- 5.03 months (the maximum term 18 months). In case of gene IL10 G(-1082)A polymorphism we determined that patients with CAD diagnose and A alleles gene IL10 had unfavorable outcome more often than patients with homozygous G alleles. Survival time from end point from carrier genotype GA and AA is 11.68 +/- 0.67 months against 12.69 +/- 0.65 months from carrier phenotype GG gene IL10 (chi2 = 4.13, p = 0.042). The group studied do not differ significantly with respect to the distributions of gene IL6 G(-174)C alleles and genotypes. However in case combined group studies of gene IL10 G(-1082)A polymorphism and IL6 G(-174)C polymorphism we determined that patients with CAD diagnose and carrier genotype GG gene IL6 and genotype GA and AA gene IL10 had unfavorable outcome more often (survival time 11.01 +/- 1.24 months) than patients with genotype CC and CG gene IL6 and genotype GG gene IL10 (survival time 13.28 +/- 0.83 months) chi2 = 10.23, p = 0.017. The obtained data allows assuming the important role of the IL6 and IL10 genes which are responsible for functioning of inflammation system, in the accelerated formation of failures at the patients who had a coronary syndrome.

We investigated the association of polymorphisms of genes FGB G(-455)A and PROCC(-1654)T with coronary artery disease (CAD) in the Russian population. A total of 1145 patients with CAD diagnose on the basis of clinical studies in cardiological hospitals of Moscow, St. Petersburg, Kazan, Chelyabinsk, Perm, Stavropol and Rostov-on-Don. Supervision term was 1.14 +/- +/- 0.33 years (the maximum term 3.2 years). The group studied do not differ significantly with respect to the distributions of G(-455)A alleles and genotypes. However in case of gene PROC C(-1654)T polymorphism we determined that patients with CAD diagnose and Talleles of PROC gene had unfavorable outcome more often than patients with homozygous C alleles. Survival time from end point from carrier phenotype TT and CTis 2.19 +/- 0.18 r. years against 2.46 +/- 0.16 from carrier phenotype CCgene PROC. The obtained data allows to assume the important role of the genes which are responsible for functioning of system of a hemostasis, in the accelerated formation of failures at the patients who had a coronary syndrome.

We studied the level of lipid peroxidation and the activity of antioxidant enzymes (superoxide dismutase and catalase) in various tissues of adult Xenopus laevis after an initial exposure to hyperbaric oxygenation at the developmental stage 38. We have found that irrespective to the mode of treatment, the level of lipid peroxidation and activity of antioxidant enzymes in the brain, lungs, and blood of these animals were higher as compared to control animals. We demonstrate that, after the exposure of adult animals to hyperoxia, if they were earlier subjected to hyperbaric oxygenation (0.2 MPa) at stage 38, there was no intensification of lipid peroxidation or changes in the activity of superoxide dismutase and catalase. In adult animals initially subjected to hyperbaric oxygenation at the same stage of development but at the pressure--0.7 MPa, the second exposure to hyperoxia led to a drastic intensification of lipid peroxidation in the brain; in some animals, an increased level of lipid peroxidation products in the lungs was observed.

Mice were exposed to helium-oxygen conditions (3.6 MPa, 5 sessions). Compression lasted for 6 h, isopression - 5 days, decompression - 18 h. The interval between sessions was 10 days. The present study has revealed that hyperbary increases the level of diene conjugates and shift bases in the erythrocyte membranes and plasma only after 1 and 3 sessions. Superoxide dismutase is suppressed after 3 and 5 sessions. Catalase activity remains unchanged. The effect of hyperbary on the induction of chromosome aberrations in bone marrow, cornea of the eye and germinal tissues has been studied. Bone marrow has been detected as more sensitive to hyperbary. Induction of aberrations in bone marrow cells has observed for 3 months.
