Figure 3. Healthy naïve BALB/c mice exhibit increased respiratory resistance to methacholine (MCh) following 3-day exposure to N-SOA.

Figure 3

(a) The total lung resistance (Rrs) to methacholine shows a dose-response relationship to increasing concentrations of N-SOA with the methacholine dose-responsive curves for N-SOA 100 μg/m3 and N-SOA 150 μg/m3 (#p < 0.05, n = 6–11/group). (b) The maximum resistance (Rrs max) showed significant dose-responsive increased to progressively higher concentrations of N-SOA (p < 0.05, r = 0.627, Spearman correlation, n = 6–11/group).
