Fig. 5. Effects of hesperidin and hesperetin on protein expressions of NF-κB (A) and iNOS (B) in liver of AAPH-induced rats. Values are mean±standard deviation. Different letters (a-d) are significantly different (P<0.05) among groups by Duncan’s multiple range test. NF-κB: nuclear factor-kappa B, iNOS: inducible nitric oxide synthase, AAPH: 2,2'-azobis (2-aminopropane) dihydrochloride.
