Effects of MgIG on body weight and pulmonary function in COPD rats. A Changes of body weight of the rats during 30-day COPD model construction. B Changes of body weight of the rats in different groups during treatment. C Comparison of FEV0.3 of rats in different groups after treatment for pulmonary function evaluation. D Comparison of FVC of rats in different groups after treatment for pulmonary function evaluation. E, Comparison of FEV0.3/FVC of rats in different groups after treatment for pulmonary function evaluation. All data were presented as mean ± standard deviation (n = 10 in each group). Statistical significance of differences were determined by one-way ANOVA. ***P < 0.001 and **P < 0.01 compared to CON group. ^###P < 0.001, ^##P < 0.01 and ^#P < 0.05 compared to MDL group. Abbreviations: FEV0.3, forced expiratory volume in 0.3 s; FEV0.3/FVC, forced expiratory volume in 0.3 seconds/forced vital capacity; FVC, forced vital capacity
