Roles of Antioxidant Enzymes in Erythrocytes on Hypoxic Pulmonary Vasoconstriction
Hypoxie pulmonary vasoconstriction (HPV) is of importance in egulating the distribution of blood flow in the lung, thus allowing the lung to maintain a pertinent matching between ventilation and blood flow. Recently, several authors (cf. Archer et al, 1989b) have reported that endogenous products of reactive O2 species (ROS) in the lung are the important factor for initiating HPV.
