Effects of drug treatment on expression of cytokine mRNA in airway tissue in the chronic challenge model.

<p>Values are fold expression relative to naïve animals, shown as mean ± SEM (<i>n</i> = 8). Significant differences compared to naïve animals are shown as *(p<0.05), **(p<0.01) and ***(p<0.001); compared to the vehicle-treated group as ^#(p<0.05), ^##(p<0.01) and ^###(p<0.001).
