Fig. 1. ARO inhibits neutrophils/macrophages influx in experimental COPD mice. (A) The images of neutrophils/macrophages were obtained using Diff-Quik staining and microscopy (magnification, x400; scale bar, 25 μm). Number of (B) neutrophils and (C) macrophages in BAL fluid of mice (green arrows indicate the neutrophils and red arrows indicate the macrophages). Data are expressed as the mean ± SD (^#p < 0.05 for comparison with normal control; *p < 0.05 for comparison with COPD group). NC: normal control mice; COPD: cigarette smoke exposed/LPS-administered mice; ROF: 5 mg/kg ROF-treated COPD mice; ARO 5: 5 mg/kg ARO-treated COPD mice; and ARO 10: 10 mg/kg ARO-treated COPD mice.
