TUNEL-stained lung tissue sections showing inhibition of DNA fragmentation (shown in red) by the PPI esomeprazole. Animals injured by bleomycin instillation were treated with vehicle or esomeprazole (prophylactic) prior to sacrifice and staining for DNA fragmentation. Representative images are shown. The nuclei are stained with DAPI. DAPI 4′,6-Diamidino-2-Phenylindole.
