[Evaluation of specific IgG content to nutritional antigens in patients with metabolic syndrome].

Specific antibodies to food antigens are detected both in healthy individuals and in various pathologies, including those of the gastrointestinal tract, neuro- and autoimmune diseases. In fact, there are no studies concerning the level of specific IgG to food antigens in metabolic syndrome. A comparative analysis of the concentration of specific IgG to food antigens in patients with metabolic syndrome and healthy people was carried out.

[The reasons for the formation of tolerance to food antigens].

One of the main issues of the peculiarities of the immune reactions of the gastrointestinal tract is the mechanisms of ensuring tolerance to food antigens. Concentrations of antibodies to food antigens actually reflect the state of the intestinal mucosa barrier function, and the degree of penetration of antigens into the blood determines the level of immune response to them. of the study was to determine the risk criteria for violation of tolerance to food antigens.

[Role of shedding in the activity of immunocompetent cells with reagin protection mechanism].

In work the data on studying of a parity of the maintenance of the soluble and membrane form of antigen CD23 at almost healthy faces is cited. To the specified sign 3 groups are allocated: in parallel low maintenance membrane and free CD23 (1 group), simultaneous increase of their concentration (2 group) and increase CD23 against significant decrease in concentration sCD23 (3 group). The conclusion becomes that photolytic shedding CD23 is made by the activated cells at increase in the maintenance of phenotypes of lymphocytes CD23+.

Serum apolipoproteins in relation to intakes of fish in population of Arkhangelsk County.

Background: Diets rich in omega-3 fatty acids and low in saturated fat were found beneficially associated with blood lipids and cardio-vascular health. Lean reindeer meet and local cold water white-fish species high in omega-3 are among the main sources of nutrients in the rural area of the Nenets Autonomous Okrug (NAO) in Russia and are not normally consumed by the urban population from the same region. The aims of the study were firstly, to compare serum lipid profiles of residents of urban (Arkhangelsk city) and rural (NAO) regions of Arkhangelsk County, and secondly, to investigate the effects of fish consumption on the predictor of cardiovascular events apolipoprotein (Apo) B/ApoA-I ratio in these populations.

[Immune response to vaccination by Grippol in female northerners from Arkhagel'sk].

The immune-system condition of virtually healthy subjects (aged 35-45) was studied before vaccination ("Grippol") and 1 week later. An intense formation of antibodies to virus hemagglutinin is associated with lymphoproliferative reaction combined with differentiation of immune-competent cells (ICC) and with a higher phagocyte activity. A lack of any changed reactions to the administered antigen is interrelated with a deficit of phagocyte protection and with an activated ICC apoptosis.
