Influence of nitroxoline on structure мicrobiotic vagina of rats in the chronic inhalation route
Aim. To study the chronic inhaled effect of nitroxolin on the condition of vaginal microbiocenosis in rats. Materials and Methods. In the experiment, 4 groups of nonlinear female rats were used, 3 experimental (10 individuals each), which were formed depending on the concentration of the compound...

To study the chronic inhaled effect of nitroxolin on the condition of vaginal microbiocenosis in rats. Materials and Methods. In the experiment, 4 groups of nonlinear female rats were used, 3 experimental (10 individuals each), which were formed depending on the concentration of the compound - subliminal (5 mg/m3), threshold (5 mg/m3), superfamily (45 mg/m3) and 1 control (6 animals).
