H2S reduces the number of ED-1-positive cells in lung tissues on the 7th day. a–e Immunohistochemistry staining of ED-1. a In the control group, ED-1-positive cells in the interstitial tissue were rare; b In the model group, the number of ED-1-positive cells were significantly increased; c, d In the treatment group, comparison with the model group, the RA contained significantly fewer ED-1-positive cells in the lung tissues; e In the NaHS group, ED-1-positive cells were equivalent to that of control mice. Data are presented as the mean ± SD. *** P < 0.001 versus control group. ### P < 0.001 versus modle group
