Patients and methods: Thirty male Wistar rats randomly were divided into five experimental groups of six animals each. The animals were received 50, 100, 200, and 400 mg/kg CNPs for 14 consecutive days. At the end of the experiment, the rats were euthanized and histopathological evaluation of the liver and renal tissues, as well ass, the markers of serum oxidative stress including thiobarbituric acid reactive substances, total sulfhydryl content, and antioxidant capacity (using ferric reducing/antioxidant power assay) were assessed. Hematological parameters and the activity of liver function enzymes were also measured. Results: The results of this study showed that CNPs caused no significant changes in the activity of liver enzymes, hepatic and renal histopathology and hematological parameters, while significantly improved serum redox status. Conclusion: Acute administration of pullulan-mediated CNPs is safe and possess antioxidant activity. Keywords: green synthesis, metal oxide, sol-gel, toxicology, radical scavenger
