[Immunity and normal pharyngeal microflora in persons living in a technogenically exposed area].

The impact of industrial emissions of an aluminum plant of immunity and pharyngeal mucosal biocenosis were studied in healthy individuals living in the Sovetsky district. The effect of sodium fluoride in various concentrations on the activity of metabolic enzymes in the bacterial Staphylococcus epidermis cells isolated from the pharyngeal mucosa of the healthy individuals was also studied. The persons living in the Sovetsky district were found to have higher values of cellular immunity, an increase in the quantitative composition of the oral microflora being observed when its qualitative composition was worse. Various concentrations of sodium fluoride were ascertained to have a heterodirectional impact on microbial metabolism.
