Effect of LPS on the protein expression of CRP, IL-2, and SOD in hFOB1.19 cells, as determined by ELISA. ELISA analysis demonstrated that after treatment with LPS, the concentrations of CRP and IL-2 gradually increased in hFOB1.19 cells and then decreased after 24 h of treatment (A and B). SOD activity gradually decreased in hFOB1.19 cells and then increased after 24 h of treatment (C). The data are expressed as the means ± SDs (**p < 0.01, *p < 0.05)
