Relative fluorescence intensity showing quantitatively the effect of roxithromycin on iNOS expression in SM-exposed SAE and BTE cells. Average fluorescence intensities were computed from cells (n ≥ 10) in each sample and are expressed relative to the control (unexposed cells). RXM, roxithromycin. ***P < 0.001 versus cells exposed to SM only.
