Figure 3: The effect of 48 h treatment with different concentrations of sodium benzoate (0.125, 0.25, 0.5,1, 2 and 3 mg/mL) against aluminum maltolate (500 μM) cytotoxicity. Cell viability was determined using MTT assay. The values were expressed as mean ± S.E.M of at least three independent experiments. Almal; aluminum maltolate, SB; sodium benzoate. *Significant difference P < 0.05 (#compared to the negative control group, *compared to the 500 μM aluminum maltolate group).
