Background and purpose: Natural compounds are used for prevention of inflammation. Curcumin has antioxidant and anti-inflammatory properties, and loading it into nano-phytosomes may improve its efficiency. The present study investigates the effects of curcumin and its nano-phytosome on behavioral and biochemical responses in carrageenan-induced inflammation in the mice model.Methods: The mice were divided into six groups and received oral administration of curcumin or its nano-phytosome at a dose of 15 mg/kg for seven days before the administration of carrageenan. Acute inflammation in the mice was induced by administration of carrageenan (1%) into the subplantar region of the left paw. Antioxidant activity and behavioral responses were then evaluated.Results: The results showed that the serum concentrations of antioxidant enzymes were significantly higher in the sal+sal group compared to the cara+sal group (P< 0.05). Using nanophytosome, separately and in combination with indomethacin, increased the levels of antioxidant enzymes compared to the cara+sal group (P< 0.05). Latency was significantly lower in the cara+sal group compared to the cara+sal group (P< 0.05), but it was considerably higher in other groups, especially in the cara+nano.ph.cur+indo group (P< 0.05).Conclusion: It can be stated that the nano-phytosome of curcumin could improve antioxidant and behavioral responses in inflamed mice.
