The effects of different doses of ZnONP and BZnO on antioxidant and oxidant levels in brain tissue were evaluated. Specifically, the levels of SOD (superoxide dismutase), CAT (catalase), GPx (glutathione peroxidase), MDA (malondialdehyde), and ROS (reactive oxygen species) were measured. The results are presented as mean ± SEM (standard error of the mean). Statistical analysis revealed that bars labeled with different letters (a, b, c, d) were significantly different from each other at a significance level of P < 0.05
