Family Analysis of Linkage and Association of HLA-DRB1, CTLA4, TGFB1, IL4, CCR5, RANTES, MMP9 and TIMP1 Gene Polymorphisms with Multiple Sclerosis.

Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system (CNS). Proteins of the immune system, as well as proteins that are involved in the infiltration of activated immune cells in the CNS, play an important role in the pathogenesis of MS. We investigated the association and linkage with MS of the following immune-system genes polymorphisms: HLA-DRB1,CTLA4,TGFB1,IL4,CCR5 andRANTES, as well as of the matrix metalloproteinase 9 (MMP9) and tissue inhibitor of metalloproteinase  1 (TIMP1) genes polymorphisms.

[Analysis of linkage and association of alleles of proinflammatory cytokines genes IL-6, IFNg and TNF with multiple sclerosis using transmission disequilibrium test (TDT)].

Proinflammatory cytokines Interleukin-6 (IL-6), Interferon-gamma (IFNg) and Tumor necrosis factor (TNF) are known as participants of inflammation and play an important role in pathogenesis of multiple sclerosis (MS). Based on literature data about influence of SNPs G(-308)A of TNF gene, A(+874)T of IFNG gene and G(-174)C of IL-6 gene on production of these cytokines, we investigated association of these polymorphic sites with MS. Linkage and association of alleles of these genes with MS was analyzed by transmission disequilibrium test (TDT).

[The heterogeneity of the ospa gene of Borrelia garinii and Borrelia afzelii in western Siberia and Mongolia].

48 full-length Borrelia garinii and Borrelia afzelii from West Siberia and Mongolia ospA gene nucleotide sequences was determined. Four groups of Borrelia garinii were revealed using the analysis of nucleotide sequences. The most variable ospA gene region was demonstrated to be included in region where the antigenic determinants of protein were encoded.

[Symptomatic therapy of bladder hyporeflexia in patients with multiple sclerosis].

Symptomatic therapy of bladder hyporeflexia in patients with multiple sclerosis by intermittent catheterization in cases of insufficient efficacy of alpha-adrenoblockers allows to prevent bacterial infection complications and chronic renal failure and to achieve significant improvement of quality of life of such patients.

[Heterogeneity of the gene P83/100 of Borrelia borrelia burgdorferi sensu lato complex].

The 35 full-length Borrelia burgdorferi sensu lato complex a83/100 gene nucleotide sequences were determined. High level of homology was observed in the nucleotide sequences corresponding to the strains and isolates of Borrelia fzelii. The analysis of the nucleotide sequences revealed two groups of Borrelia garinii.

[New methods of prevention, diagnosis and treatment of tuberculosis in children].

The follow-up included two groups of schoolchildren: 862 were repeatedly given BCG and 725, BCG-M vaccines. It was demonstrated that both vaccines had the same effectiveness and the latter could also be used. Upright tomographic findings in 70 children showed that it was highly informative for the diagnosis of intrathoracic tuberculosis in children, especially for that of bronchoadenitis.
