Figure 5

The effects of LRE on bronchial smooth muscle deposition in prolonged OVA-challenged mice. (A) Representative photomicrographs of α-smooth muscle actin (α-SMA)-stained. All figures are in 10× magnification. (B) Peribronchial smooth muscle deposition was quantified as the thickness of peribronchial α-SMA-stained layer. Values are expressed as means ± SEM (n = 7 per group). OVA-group is significantly different from the normal group. *p < 0.05; **p < 0.01, ***p < 0.001 and ****p < 0.0001 indicates significant difference from OVA.
