we exposed monolayer cultures of pulmonary artery endothelial cells or plasma membranes derived from these cells to hypoxic ( 0 and 5 % o2 ) and normoxic ( 20 % o2 ; control ) conditions and measured cellular contents of malondialdehyde and conjugated dienes , plasma membrane fluidity and lipid composition , and plasma membrane-dependent transport of 5-hydroxytryptamine ( 5-ht ) .
