Immunocytochemical detection of the inducible type of NO synthase (iNOS) in the bronchoalveolar lavage fluid (BALf) cells. Representative photographs are shown in panel A (healthy subject: HS); B (idiopathic pulmonary fibrosis: IPF); and C (eosinophilic pneumonia: EP). iNOS 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.
