Effects of resveratrol on iNOS expression (a), NO production (b), COX-2 expression (c), and PGE₂ production (d) in CBNPs-treated A549 cells. Cells were pre-treated with resveratrol for 1 h before addition of CBNPs (25 μg/mL) for 24 h. Bars represent the mean ± S.E.M. from six independent experiments. ^###P < 0.001 vs. control group (without any treatment). ^*P < 0.05, ^**P < 0.01, ^***P < 0.001 vs. CBNPs (25 μg/mL) group
