Effect of roxithromycin on SM cytotoxicity in SAE and BTE cells. Various concentrations of roxithromycin were added to cells exposed to 100 μM SM. Cell viability was measured using the MTS assay 24 h after exposure, and is expressed as a percentage of the value obtained from cells unexposed to SM ("U"). ***P < 0.001 versus control (cells exposed to SM without roxithromycin, "C").
