Fig. 5.

Percent of nonvolatile solids content of mucous liquid secreted by gut-corrected CF and non-CF porcine bronchi. Percent solids are shown for each of the indicated treatments. Number of individual airways are shown in parentheses. Means ± SE are shown for non-CF bronchi, whereas only single samples were obtained for bronchi from pigs with CF in each treatment group. Dotted horizontal lines (above and below bars) indicate the 95% confidence intervals for non-CF percent solids in each group. All three single values for mucous liquid percent solids from the CF bronchi fell well outside the 95% confidence intervals for non-CF bronchi responses.
