From: Ghrelin therapy improves lung and cardiovascular function in experimental emphysema
Immunohistochemistry for F4/80 (total macrophages (a), iNOS (M1 macrophages (b) and arginase-1 (M2 macrophages (c). C: control; ELA: elastase-induced emphysema; Sal: i.p. injection of saline; Ghr: i.p. injection of ghrelin. Boxes show the interquartile range (25th–75th percentile), whiskers encompass the range (minimum–maximum), and horizontal lines represent the median in 10 animals/group. * vs. C-Sal. # vs. ELA-Sal
