Toxicological sanitary characterization of titanium dioxide nanoparticles introduced in gastrointestinal tract of rats. Communication 2. Intestinal microbiocenosis condition and allergic sensitivity.

: Intestinal microbiocenosis condition, cytokine IL-6, IL-10 and TNF-alpha levels and allergic sensitivity in experimental systemic anaphylaxis test were studied in rats that received intragastrically nanoparticles of titanium dioxide. The results obtained were discussed from the standpoint of possible health risks related to nanodimensional titanium dioxide exposure.
