  1. Lung function was measured 12 weeks after the start of CS exposure (group 1) or 29 days after the start of intraperitoneal injection of CSE (group 2). CS, cigarette smoke; CSE, cigarette smoke extract; N1, controls of CS exposure group; C1, CS exposure group; N2, controls of intraperitoneal injection of CSE group; C2, intraperitoneal injection of CSE group; Raw, airway resistance; Cdyn, lung dynamic compliance; PEF, peak expiratory flow; Ti, inspiratory time; Te, expiratory time. Valus are means ± standard deviation, ★P < 0.01 compared with the respective group N.
