The action of ligustrazine remained in both control and chronically hypoxic rats after administration of an arginine analogue which blocks synthesis of the endothelial relaxant factor nitric oxide. This and previous evidence suggest that ligustrazine is a non-endothelial-dependent pulmonary vasodilator.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/4/10/1223}, eprint = {//www.qdcxjkg.com/content/4/10/1223.full.pdf}, journal = {European Respiratory Journal} }
