Effect of ECC-BYF III on pulmonary function of COPD rats. ECC-BYF III (dosage: 6.48 mg/kg, q.d) or N-Acetylcysteine (dosage: 54 mg/kg, q.d) was given treatment groups by intragastric administration from 9 to 16 weeks. A Changes of VT in all groups. B Changes of MV in all groups. C Changes of PEF in all groups. D Changes of EF50 in all groups. E Changes of FEV0.3 in all groups. F Changes of FVC in all groups. H Changes of RI in all groups. I Changes of Cydn in all groups. All data are expressed as the mean ± SE, (n = 6). Animals are randomly selected. **P < 0.01 vs. the normal group; #P < 0.05 vs. the model group, ##P < 0.01 vs. the model group
