The Role of Regulatory T Cell in Nontypeable Haemophilus influenzae-Induced Acute Exacerbation of Chronic Obstructive Pulmonary Disease
Lung function testing on mice. Invasive lung function was investigated with anesthesia and tracheal instrumentation. FEV0.1 (forced expiratory volume in 100 ms), FRC (functional residual capacity), and RI (airway resistance) in the NC, CS, NTHi, and NTHi + CS groups were shown in (a), (b), and (c), respectively. (d) Dynamic lung function, with x-coordinate representing lung volume and y-coordinate representing airflow. (e) Lung volume at the end of each inspiration. n = 5–7 in each group; each test was repeated three times. Data was expressed as mean ± SD. Analysis of differences among groups was conducted with one-way ANOVA-LSD. ,, and versus NC; and versus CS.
