Objective To investigate the effect of nitric oxide(NO) inhalation in endotoxin-induced acute lung injury mice. Methods Ninety SPF mice were randomly assigned to the normal group(group A), ALI group(group B)and ALI+NO group(group C). The number of endothelial progenitor cells was counted and the level of Interleukin-10(IL-10) and myeloperoxidase (MPO) were measured. Results Endotoxin administration resulted in pulmonary edema. The pulmonedema was lightened and the level of MPO were decreased by the inhalation of nitric oxide while the level of IL-10 increased. Conclusion NO inhalation can mitigate acute lung injure. The decline of EPCs and MPO and the increase of IL-10 may be one of the mechanism.
