Effect of DDS on viability of paraquat (PQ) treated HDFs. DDS was added to HDFs, and let stand for 3 h before treatment with 1 mM paraquat. Cell viability was assessed after 48 h with a Cell Counting Kit-8. Positive controls were treated with DPI (5 µM) for 30 min or with NAC (2 mM) for 3 h prior to paraquat exposure. Data are normalized to control and the results are expressed as means ± SE of three experiments. Results expressed as % of control rate. Marks indicate the significant difference, P <0.005 (#, from untreated control cells (CC); *, from only paraquat treated control cells (C)).
