Figure 5From: Prolonged ozone exposure in an allergic airway disease model: Adaptation of airway responsiveness and airway remodelingGoblet cell counts in the epithelium of bronchioles of mice exposed to filtered air and to 2 ppm ozone for 4, 8, and 12 weeks. The results are expressed as number of cells per millimeter of basement membrane. Horizontal bars represent median values. * p < 0.05 compared to the group exposed to filtered air.Back to article page
