Figure 2

Equivalent doses of methacholine required to cause a 50% elevation in airway resistance (ED 50 , panel A) and the end-expiratory lung volumes (EELV, panel B) measured in 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.
