Summary of immunohistochemistry of NF-κB. a. NF-κB p65 expression in remnant right lung in each group. Statistical differences were tested using ANOVA with post hoc Tukey test. *p < 0.05, ** p < 0.01 between the indicated groups. b. Upon double staining for NF-κB and pro-SPC, majority of NF-κB positive cells revealed colocalization with pro-SPC positive immunoreactivity in the remnant right lung at 12 h after pneumonectomy. Double positive cells were fewer at 48 h after pneumonectomy
