Levels of (a) lipid peroxidation, (b) thiol protein, (c) catalase, and (d) superoxide dismutase activity in Vero cells treated with iohexol at a concentration of 100 mg iodine/mL or pretreated with 1 μM vitamin D3. Results are represented as . One-way ANOVA and Tukey posttest () were used to analyse the results. ns: not significant; , , and (2-tailed) versus control; ^$, ^$$, and ^$$$ (2-tailed) iohexol (I) versus iohexol+vitamin D (I+Vit D) groups.
