Protective action of aqueous curry leaf extract at 200 mg/kg body weight on piroxicam induced altered activities of mitochondrial Kreb's cycle (A–D) and electron transport chain enzymes (E and F). (A) The pyruvate dehydrogenase activity. (B) The isocitrate dehydrogenase activity. (C) The alpha-ketoglutarate dehydrogenase activity. (D) The succinate dehydrogenase activity. (E) The NADH-cytochrome c oxido-reductase activity. (F) The cytochrome c oxidase activity. Bar graphs represent the values of activity levels of the enzymes 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).
