From: Prevention of hyperoxia-induced bronchial hyperreactivity by sildenafil and vasoactive intestinal peptide: impact of preserved lung function and structure

Figure 5

Percentages of TUNEL-positive nuclei counted in lung cryosections (panel A) collected from rats exposed to room air (Group C) subjected to hyperoxia without any additional treatment (Group HC) and hyperoxic rats treated either with sildenafil (Group HS) or VIP (Group HV). *: p < 0.05 vs. Group C, #: p < 0.05 vs. Group HC. Representative images for TUNEL in cryosections from the studied groups are shown in panel B. Arrows indicate TUNEL-positive nuclei (green).
