Maximum tolerated dose (MTD) of 150 nm ZrO2 was determined as 500mg/kg. Hematology analysis and blood biochemical assay were determined for the evaluation of oxidative damage caused by ZrO2. Biodistribution of ZrO2 was investigated by ICP-OES and TEM.Results: Mice treated with higher dose (500mg/kg) showed significant spread in white blood cell counts (p<0.05). Especially, the serum ALT levels of 500mg/kg groups increased significantly (p<0.05) compared with the control group. ZrO2 particles would not induce any changes in appearance and micromorphology of liver at 100 and 350mg/kg. Spleen samples showed no significant changes in micromorphology of the lymphoid follicles and in the size of the red pulp after injection of ZrO2 at all doses. The serum of ZrO2-treated animals (350 and 500mg/kg) has reduced levels of SOD compared to the control group (p<0.05). ZrO2 persists in membrane-enclosed vesicles called lysosomes in the liver and spleen macrophages without abnormal changes of ultrastructure.Conclusion: These findings would contribute to the future development of ZrO2-based drug delivery system and other biomedical applications.Keywords: zirconia nanoparticles, toxicity, biodistribution, oxidative damage, ICP-OESYang YBao HChai QWang ZSun ZFu CLiu ZLiu ZMeng XLiu TDove Medical Pressarticlezirconia nanoparticlestoxicitybiodistributionoxidative damageICP-OESMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 14, Pp 5175-5186 (2019)
