Micrographs of the lung (A) in CTL (a), Db (b); Ex (c); Db + Ex (d) groups. Comparison of histological score (B) and mean alveolar number (MAN) (C) in the lung tissue of different groups illustrated in this figure. (Magnifcation:×40, scale bar: 40 μm).Blue arrows indicate inflammation and orange arrows indicate congestion. Data are means ± SEM .*** P < 0.001 compared to the CTL. # P < 0.05 & ## P < 0.01 compared to the Db
