Immunocytochemical detection of the 3-nitrotyrosine (3-NT) in the BALf cells. Representative photographs are shown in panel A (healthy subject: HS); B (idiopathic pulmonary fibrosis: IPF); and C (eosinophilic pneumonia: EP). 3-NT immunopositivity in BALf cells is correlated with FENO (D) and Calv levels (E). r is the correlation coefficient. The lines and p values correspond to the fitted regression equation.
