dc.description.abstract Pleurotus ostreatus (P.o) is a culinary mushroom which is commonly called as “oyster mushroom” belonging to the Basidiomycetous fungi of the order Agaricales and family Pleurotaceae. Objectives. 0e present study investigates the antiinflammatory potential of P.o and the underlying mechanisms of activity. Materials and Methods. Anti-inflammatory activity was evaluated using suspensions of freeze-dried and powdered (SFDP) P.o and acetone extract (AE) of P.o in normal and alloxaninduced diabetic rats using the carrageenan-induced rat paw oedema model. 0e mechanisms by which P.o is mediating the antiinflammatory activity were studied using in vivo and in vitro assays. Results. At doses of 500–1000 mg/kg, the SFDP of P.o showed long-lasting activity at both early and late phases of carrageenan-induced rat paw oedema. 0e dose of 750 mg/kg showed the most potent inhibitory activity (92% inhibition) in healthy rats. 0e AE of P.o showed maximum inhibition of oedema of 87%. P.o exerted protective effects on the inflammatory pathologies in rats with diabetes. 0e possible mechanisms by which P.o mediates the anti-inflammatory activity were antihistamine activity (52.1%), inhibition of cell migration to the site of inflammation (45.4%), in vitro membrane stabilizing activity (52.6%), and inhibition of nitric oxide (NO) production (91.2%) (P < 0.05). Dose-dependent inhibition of NO production was seen with in vitro treatment of rat peritoneal cells with AE of P.o (r � 0.95; P < 0.05). Discussion and Conclusion. 0e promising activity of culinary mushroom P.o against inflammation suggests its potential application as a functional food during inflammatory conditions. en_US
