Relative concentrations of total cellular iron determined by atomic absorption spectroscopy 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) in comparison with the control; $, $$, and $$$ (2-tailed) iohexol (I) versus iohexol+vitamin D (I+Vit D) groups.
