Protective mechanism of aqueous curry leaf extract at 200 mg/kg body weight dose against piroxicam induced oxidative stress in rat stomach. (A) The serum PGE level. (B) The gastric tissue PGE level. (C) The gastric tissue free hydroxyl radical level. (D) Xanthine oxidase activity. (E) Xanthine dehydrogenase activity. The bar graphs represent the values of the different parameters studied and all the values are expressed as mean ± S.E.M. where *P ≤ 0.001 vs. control, **P ≤ 0.001 vs. piroxicam treated animals (one-way ANOVA followed by Scheffe’ multiple comparison test).
