ABSTRACT
We studied the effect of an experimental synthetic organoselenium compound 2,6-dipyridinium- 9-selenabicyclo[3.3.1]nonane dibromide (974zh) on the cell composition of the red bone marrow and peripheral blood in white mice. The study drug co-administered with Yersinia pestis EV vaccine strain (103 CFU) potentiated maturation and migration of mature neutrophils from the bone marrow into the circulation. Reducing the dose of the live vaccine and the anti-inflammatory properties of the study drug made it possible to reduce the allergic reaction during the vaccination process.

We studied immunotropic properties of synthetic selenium-organic preparation 2,6-dipyridinium-9-selenabicyclo[3.3.1]nonyl dibromide (974zh). The experimental preparation reduced the cAMP/cGMP ratio, which indicated an increase in proliferative activity of cells of immunocompetent organs (thymus and spleen) in experimental animals. It was shown that 974zh intensified the immune response to Yersinia pestis EV thereby increasing the resistance to the plague agent.

We studied the effect of the organoselenium compound 2,6-dipyridinium-9-selenium-bicyclo[ 3,3,1]nonan dibromide (974zh) on the severity of pathological changes in the organs of experimental animals immunized with live tularemia and brucellosis vaccines. It was found that 974zh reduced reactogenicity of vaccines for experimental animals. Our findings indicate the prospects for further studies of the effects of 974zh on the functional state of experimental animals.
