Effects of Pb on PS-MP induced ROS production for 24 h by ROS assay and induced nitric oxide production for 24 h by NO assay in RAW 264.7 cells. Cells were adjusted to 106 cells/mL were treated for 24 h with Pb and PS-MP (100 μg/mL). Control was treated with medium only. Results are show by mean ± S.E.M. (n = 3). *P < 0.05 versus only PS-MP, **P < 0.01 versus only PS-MP.
