Toxicological sanitary characterization of silver nanoparticles introduced in gastrointestinal tract of rats

AbstractWater suspensions of silver nanoparticles were introduced intragastrically to growing male Wistar rats daily for 28 days. There were studied animals mass gain, relative masses of viscera, intestinal barrier resistance against protein macromolecules, DNA oxidative damage, tissue non-protein thiol levels, first and second phase of xenobiotic detoxication system activity, lysosomal membranes stability in liver together with routine blood biochemical and hematological indices and caecal’s microbiocenose state. The data testifying to possible toxic risks, connected with reaction of silver’s nanoparticles is obtained.
