[Subpopulations of Regulatory T-lymphocytes in the Peripheral Blood of Patients with Rheumatoid Arthritis].

Background: Rheumatoid arthritis (RA) is an inflammatory rheumatic disease associated with a dysfunction of the T cell-mediated tolerance and leading to the disability of working population. The regulatory CD4' T cells play an important role in the regulation of autoimmunity and can suppress immune responses. With that, there is no consensus on the content of these lymphocytes and their role in the pathogenesis of RA.

[Circulating regulatory T-cells and changes in the subpopulation composition of lymphocytes in colorectal cancer patients].

Data on the frequency of peripheral Treg cells, their functional activity, as well as their relationship to changes in characteristics of cellular immunity in patients with colorectal cancer (CRC, n=42) and healthy donors (n=34) are presented in the article. Assessment of the expression of molecular markers of lymphocytes was performed by multicolor flow cytometry. It was shown that the number of these cells is significantly increased in CRC patients (p<0,05).

[The effectiveness of BACTEC MGIT 960 system hit analysis of surgery material of patients with tubercular spondylitis].

The article considers the comparison of effectiveness of cultivation of 290 surgery samples from focus of destruction in patients with tubercular spondylitis in liquid medium Middlebrook 7119 with fluorescent detection of growth and two dense egg medium -Levenschtein-Yensen and Finn-II. The sensitivity of methods of inoculation in liquid medium Middlebrook 7H9 and in dense egg mediums has no difference (38.2% and 43.

[Alterations of lymphocyte subsets and indicators of immune suppression in patients with acute pancreatitis].

The Aim Of Study: Assessment of changes in lymphocyte number and some indicators of the immune suppression (frequency of regulatory T cells (Treg), the level of expression of CTLA-4 (cytolytic T lymphocyte-associated antigen 4) and interleukin (IL)-10) in patients with acute pancreatitis (AP).

Materials And Methods: Peripheral blood samples of 21 patients with AP (including 11 patients with pancreatic necrosis (PN)) were studied for analysis of lymphocyte subsets and 11 blood samples of healthy donors were estimated as control. Evaluation of the expression of molecules of lymphocytes was carried out by flow cytometry.

[Use of transpedicular fixation in the surgical treatment of tuberculosis spondylitis and chronic hematogenous osteomyelitis of the vertebral column].

The efficiency of applying various posterior instrumental fixation modes (semirigid constructions and transpedicular fixation (TPF)) was comparatively analyzed in 91 patients with tuberculosis and and osteomyelitis of the spine. TPF was shown to have some advantages in correcting its deformity and preventing the latter's losses, reducing the number of complications in the area of anterior spondylodesis.
