Figure 2

Changes in the pulmonary function in all groups. (a) Tidal volume (VT), (c) minute volume (MV), and (e) peak expiratory flow (PEF) in rats from week 0 to week 20. (b) Tidal volume (VT), (d) minute volume (MV), (f) peak expiratory flow (PEF), (g) functional residual capacity (FRC), (h) forced vital capacity (FVC), and (i) forced expiratory volume at 0.1 s (FEV 0.1) in rats at week 20. The data are expressed as the means ± SE ( = 8-12). versus the normal group, versus the normal group; versus the model group, versus the model group; versus the APL group, versus the APL group, versus the BY group, and versus the EA group.
