[Increase in the lipid peroxide content in the blood and aortas of rabbits with experimental atherosclerosis]

Content of lipid peroxides was estimated in blood and aorta of intact rabbits by means of highly sensitive polarographic method, using a mercuric electrode. Content of lipoperoxides in blood and aorta was increased 4.4- and 3.6-fold, respectively, in animals with pronounced experimental atherosclerosis. The oxidation of lipoperoxides caused a distinct increase in content of intermolecular bindings in amino-containing phospholipids in aorta of rabbits with pronounced atheromatosis.
