Galectin 3 and non-classical monocytes of blood as myocardial remodeling factors at ischemic cardiomyopathy.

Aims: To identify an imbalance of cardiac remodeling mediators and monocytes subpopulation in blood, distribution of myocardium macrophages in patients with ischemic cardiomyopathy (ICMP).

Methods: The study engaged 30 patients with ICMP, 26 patients with coronary heart disease (CHD) without ICMP, 15 healthy donors. Concentrations of TGFβ, MMP-9, MCP-1, galectin-3 were measured in plasma of blood from the coronary sinus and peripheral blood in CHD patients, as well as in peripheral blood in healthy donors, by enzyme immunoassay method.

Association between polymorphisms of cytokine genes and secretion of IL-12p70, IL-18, and IL-27 by dendritic cells in patients with pulmonary tuberculosis.

Proinflammatory cytokines are known to play a crucial role in the pathogenesis of tuberculosis, and gene polymorphisms in the promoter regions of cytokine genes were shown to substantially influence the secretory capacity of immune cells. In the present study, we analyzed the association between polymorphisms of the IL12B, IL18, and IL27 genes and the secretion of the proinflammatory cytokines IL-12р70, IL-18, and IL-27 by myeloid dendritic cells (mDCs) in pulmonary tuberculosis (PTB) patients. The study enrolled 334 patients with newly diagnosed infiltrative and disseminated PTB.

Effect of chelating agents and stress factors on zinc content in paneth cells and prostate gland cells.

The effects of chelating agents dithizone and sodium diethyldithiocarbamate on zinc content in Paneth cells and prostate gland cells were studied on rats preliminary exposed to stress factors (exercise and immobilization). Dithizone induced irreversible triphasic and sodium diethyldithiocarbamate reversible biphasic changes in zinc metabolism in cells. Preliminary stress potentiated the damaging effect of dithizone.

The role of foxp3-expressing regulatory T cells and T helpers in immunopathogenesis of multidrug resistant pulmonary tuberculosis.

Subpopulation structure of regulatory T cells and T helpers of peripheral blood in patients with newly diagnosed pulmonary tuberculosis depending on the clinical form of disease and sensitivity of Mycobacterium tuberculosis to antituberculosis drugs has been analyzed in this work. It has been shown that the leading part in immune suppression at infiltrative, dissemination, and fibrosis-cavity pulmonary tuberculosis is played by natural regulatory CD4(+)CD25(+)Foxp3(+)-T lymphocytes. Thus we estimate increase of their number in blood by drug-resistance and drug-susceptible patients.

Assessment of the relationship of chronic opisthorchiasis to Epstein-Barr virus infection as well as some cytogenetical and immunological parameters in two comparable Siberian regions.

Previous studies have shown an increase in the frequency of chromosomal abnormalities in the peripheral blood lymphocytes from opisthorchiasis patients. Some evidence suggests that there is an association between chronic opisthorchiasis and certain herpes viruses. To study the relationship of opisthorchiasis to the reactivation of Epstein-Barr virus (EBV) infection as well as the influence of opisthorchis infection on some cytogenetical and immunological parameters, we used the indirect immunofluorescence for measuring some virus specific antibodies, the cytokinesis-block lymphocyte micronucleus assay, and the quantitative immunodiffusion method for measuring immunoglobulin concentrations in serum.
