The effect of PM014 on goblet cell number. The right lower lobes of mice were dissected and stained with periodic acid Schiff. A) The arrow indicates the PAS-positive cells. B) Periodic acid Schiff (PAS)-positive mucosal goblet cells around the bronchial airway were counted and are depicted as the percentage of goblet cells, as described in the Materials and Methods section. Data are shown as mean ± S.E.M. Statistical analyses were conducted by one-way ANOVA followed by Newman-Keuls Multiple Comparison test (***p < 0.001vs. CON, ###p < 0.001 vs. CS).
