Final body weights and organ weights of the lung and mediastinal lymph nodes of male rats after repeated inhalation exposure to CWAAP-A. Results of the high-concentration intermittent inhalation experiment. Final body weights (A), right lung weights (B), and mediastinal lymph node weights (C) were measured at each sacrifice. Statistical significance was analyzed using Dunnett’s multiple comparison test compared with age-matched control (sham air) groups: *p < 0.05, **p < 0.01 and ***p < 0.001
