IONPs induced oxidative stress in the animals treated for one week and its attenuation by thymoquinone. Bar diagrams showing decrease in catalase activity after IONPs exposure and its attenuation by co-exposure of thymoquinone (A,B), decrease in superoxide dismutase activity after IONPs exposure and its attenuation by co-exposure of thymoquinone (C,D), decrease in reduced glutathione level after IONPs exposure and its attenuation by co-exposure of thymoquinone (E,F), an increase in malondialdehyde (MDA) level after IONPs exposure and its attenuation by co-exposure of thymoquinone (G,H). Data are statistically significant at (*p < 0.05). NC, Negative Control; PC, Positive Control.
