We hypothesize that functional alterations of pulmonary endothelium are likely to affect both reactivity and growth of pulmonary vessels. In this respect, NO probably has a pivotal role in modulating pulmonary vascular tone and controlling pulmonary vascular remodelling in health and disease.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/5/6/757}, eprint = {//www.qdcxjkg.com/content/5/6/757.full.pdf}, journal = {European Respiratory Journal} }
