In conclusion, exogenous surfactant may modulate the inflammatory response of the airways by affecting the chemoattractant-induced polymorphonuclear neutrophil activation. Surfactant preparations with inhibiting properties on neutrophil activation may participate in the prevention of neutrophil-induced lung damage.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/9/4/752}, eprint = {//www.qdcxjkg.com/content/9/4/752.full.pdf}, journal = {European Respiratory Journal} }
