Effect of antioxidants on hydroquinone (HQ)-induced IL-8 secretion in NHK cultures. Cells were pretreated for 30 minutes with 1% DMSO, 1 mM TMTU, or 0.5 mM NAC and exposed to HQ (125 μM). Asterisk (*) represents a significant (p < 0.05) increase from the vehicle control. Values represent the mean ± SD of four to six cultures.
