 of the pretreatment with different concentration of resveratrol (RSV) on methemoglobin formation induced by DDS-NHOH.\ Erythrocytes were pretreated with different concentrations of RSV(00, 000, 000 and 0000 μM) for 0 h at 00°C, then these cells were incubated with different concentrations of DDS-NHOH (0.0; 0.0 and 0.0 μg/mL) for 0 h at 00°C. Data are reported as means ± S.E.M from three independent experiments done in triplicate.
