Toxicological Assessment Of Intra‐Tracheal Instilled Nanoceria On Kidneys Of Sprague‐Dawley Rats, Geeta Nandyala
Theses, Dissertations and Capstones
Recent studies suggest that use of nanoceria in industry is associated with increased risk of human and environmental exposure. How inhaled nanoceria might affect the kidneys is not yet known. To investigate this possibility, Sprague Dawley rats were exposed to a single dose of 7mg/kg body weight cerium oxide nanoparticles by intratracheal instillation. Animals were sacrificed at day 1, 3, 14, or 28 days after exposure and the kidneys collected for histological and biochemical analysis. No significant difference was observed in kidney to body weight ratio between the different groups. Hematoxylin and eosin staining did not reveal any significant changes …
