Hypercapnia therapy decreased apoptosis in the lung grafts. Representative lung graft TdT-mediated dUTP nick end labeling staining (200×; A) and apoptosis index (B) in sham-operated, isograft, allograft, and hypercapnia groups. Apoptosis of the cell was represented by brown-yellow staining in the nuclei (arrows in A). Differences in apoptosis indices among groups were analyzed by one-way ANOVA followed by the Student–Newman–Keuls post hoc test. #P < 0.05 versus allograft group.
