[Local immunity and methods for its assessment upon exposure to ambient air-polluting biologicals].

The investigators studied the impact of biological air contamination by the dusts resulting from protein feedstuff manufacture and grain on local immunity of the mucosae in children and adults living in the areas that were differently distant from industrial objects, the sources of contamination, as well as in workers of the shops contaminated by dust containing various amounts of protein. The studies showed that the workers of a biochemical plant exhibited a considerable change in the majority of immunological parameters (lysozyme activity, heterophile antibody titers, salivary and skin bactericidity, salivary total and R-protein, and immunoglobulins A, M, G, and E). There was a significant decrease in salivary IgA activity.

[Experimental data for evaluation of biological effect during exposure to chemical and biological factors].

Joint effects of lysin, eprin and formaldehyde in acute and subacute experiments were investigated. As shown, this effect can be evaluated as a partial summing with coefficient 1.84.
