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

Figure 4

Representative images of hematoxylin/eosin-stained lung sections (panel A) collected from control rats exposed to room air(C), rats subjected to hyperoxia without any additional treatment (HC), and hyperoxic rats treated with either sildenafil (HS) or VIP (HV). Mean linear intercept values (panel B) and percentage of edema surface (panel C) were determined from the lung sections of the rats in the protocol groups. *: p < 0.05 vs. Group C, #: p < 0.05 vs. Group HC.
