Fig. (1) The cytotoxicity of skin sensitizers in MCF-7 cells and BALB/3T3 clone A31 cells under normal or high glucose conditions. MCF-7 cells were incubated in various concentrations of eugenol (A, C), CA (B, F), DNCB (C, G), and isopropanol (D, H) under normal or high glucose conditions for 24 hours. Cytotoxicity was evaluated by LDH cytotoxicity assay. All experiments were performed in triplicate.
