Hypochlorous acid contributes to cochlear injury. (A) MTT assays show that sodium hypochlorite (NaOCl) inhibits the viability of HEI-OC1 cells in a dose-dependent manner. (B) Combination of hydrogen peroxide (H2O2) and myeloperoxidase (MPO) augments cisplatin cytotoxicity to HEI-OC1 cells. (C) N-Acetyl-L-cysteine (NAC) and ML-171 inhibit the enhancement of cisplatin cytotoxicity by the combination of H2O2 and MPO. Data are mean ± SD (n = 3). *p < 0.05.
