Immunogenesis in White Mice Infected with Yersinia pestis with Different Plasmid Composition.

Morphological changes in the immunocompetent organs of white mice with experimental plague infection manifested in activation of the immune response of different degree and pathological process of different severity that depended on the plasmid composition of Y. pestis. Widening of the T-dependent zones in the immune organs of white mice infected with isogenic strains of Y.

Intensity of Oxidative Stress in Mongoloid and Caucasian Patients with Type 1 Diabetes Mellitus.

Specific features of LPO were studied in Mongoloid and Caucasian patients with type 1 diabetes mellitus. The intensity of LPO in Mongoloid patients was lower than in Caucasians: the level of primary and intermediate products was by lower 1.53 and 1.

Changes in Peripheral Blood Monocytes and Liver Macrophages in Male Rats after Benzo(a)pyrene Injection.

Intraperitoneal injections of benzo(a)pyrene to male rats in a total dose of 60 mg/kg modified the production of ROS and the phagocytic potential of blood monocytes by modulating their potential bactericidal activity. The lysosomal system (particularly the secondary lysosomes) of liver macrophages was activated, which promoted fusion of the hydrolytic potentials of macrophages and monocytes. These results indicated that the toxin modulated the cellular immune homeostasis and the level of general nonspecific resistance.

Lipid peroxidation and mitochondrial superoxide dismutase-2 gene in adolescents with essential hypertension.

The study of LPO processes in adolescents of different races with essential hypertension revealed that Mongoloids exhibit oxidative stress by altering the level of the formation of diene conjugates, the primary LPO products. Caucasians increased the levels of both primary and end products of LPO, diene conjugates, and malondialdehyde. The revealed differences can be genetically determined because ethnic differences in the frequency of SOD2 gene Ala16Val polymorphism and its contribution to the biochemical phenotype were reported.
