PD ameliorated oxidative stress by up-regulating the Nrf-2 signaling pathway in CRKP-infected A549 cells. CRKP-induced cellular injury induced by PD and ML385 was detected by LDH (A). The cells were incubated with CRKP and PD for 12 h and the concentration of SOD (B), MPO (C) were assessed by corresponding kits. A representative result of the protein expression of Nrf-2 among all groups was analyzed by western blot, and a statistical result was calculated (D-E). ##P < 0.01 vs. the control group; *P < 0.05 and **P < 0.01 vs. the CRKP alone group.
