TOS: total oxidant status, GPx: glutathione peroxidase activity, and TAC: total antioxidant capacity. The data were presented as the mean ± SD. The one-way ANOVA test was used to compare all the groups, and the post hoc (Tukey) test was performed to compare two groups. SD: standard deviation. P < 0.05 was considered as bold values.
