abstract：:Oxidation converts low-density lipoprotein (LDL) into a cytotoxin in vitro. Oxidized LDL exists in vivo in atherosclerotic lesions and possibly in plasma. Many cell functions are altered in vitro by oxidized LDL, but few have been examined in vivo. To test whether oxidized LDL could injure endothelial cells and alter ...
