From: Increase of nitrosative stress in patients with eosinophilic pneumonia
Exhaled nitric oxide (NO) levels in the study subjects. Panels show the fractional exhaled NO (FENO) levels (A), the alveolar NO (Calv) levels (B), airway wall NO (JawNO) (C), and corrected Calv (D). Horizontal lines represent the mean value of the exhaled NO levels. HS = healthy subject; IPF = idiopathic pulmonary fibrosis; EP = eosinophilic pneumonia; N.S = not significant.
