Figure 3From: Prolonged ozone exposure in an allergic airway disease model: Adaptation of airway responsiveness and airway remodelingMethacholine-induced airway responses measured by whole-body plethysmography in BALB/c mice exposed to filtered air and to 2 ppm ozone for 8 h per day for 4, 8, and 12 weeks. Values are means ± SE; n = 6 mice per group. * p < 0.05 compared to the group exposed to filtered air.Back to article page
