Measurements of the body weight and lung function each month. Six- to eight-week-old male C57BL/6J mice were exposed to CS for 6 months or CS for 6 months and an intranasal instillation of LPS on days 1 and 14. a Trends in the body weights of mice in the control group (n = 6), CS group (n = 6) and CS + LPS group (n = 6). b Lung function of mice in the control group (n = 6), CS group (n = 6) and CS + LPS group (n = 6). Penh, enhanced pause. Data are presented as the means ± SD, N = 6; #P < 0.05; ##P < 0.01 for the comparison of the CS group with the control group; *P < 0.05; **P < 0.01; ***P < 0.001 for the comparison of the CS + LPS group with the control group; &P < 0.05; &&P < 0.01 for the comparison of the CS + LPS group with the CS group
