Impact of different experimental groups on l-arginine (l-arg)-induced pulmonary injury in rats; (a) Histopathological changes of the pulmonary tissue stained with H&E. Black arrows and arrow heads point to congestion and perivascular leukocytic cell infiltration, respectively. (b) Pulmonary destruction score. Data are represented as median and interquartile change, (n = 6). *, *** significantly difference at p-value < 0.05 and 0.001, respectively, using Kruskal–Wallis test followed by Dunn multiple comparison test (b), (magnification X: 400, bar = 25 μm).
