Fig. 4From: Ghrelin therapy improves lung and cardiovascular function in experimental emphysemaCollagen fibre content in alveolar septa (a) and pulmonary vessel wall (b). Representative photomicrographs of alveolar septa (c) and pulmonary vessels (d), stained with the Picrosirius-polarization method. Note the enlargement of alveolar space in the ELA-Sal group. 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-SalBack to article page
