Fig. 5From: Basal Nucleotide Levels, Release, and Metabolism in Normal and Cystic Fibrosis AirwaysATPase activity in nasal lavages. ATPase activity in baseline lavages (B), after methacholine treatment (M), and after ipratropium bromide followed by methacholine (I+M) from normal (n = 4) and cystic fibrosis (CF; n = 3) patients. For comparisons, * denotes p < 0.05, and ** denotes p < 0.005.Back to article page
