[Lipid peroxides and atherosclerosis. Free radical peroxidation of polyene lipids in the blood in ischemic heart disease].

Examination of blood in 114 males (35--60 years of age) with stage III of lipid hydroperoxides, acylhydroperoxides, intermol ecular cross-links in the aminophosphatides and secondary products of lipoperoxidation was increased considerably as compared to that in practically healthy males (30) of the same age. The activity of blood glutathione lipoperoxidase in the examined group of patients was sharply reduced.
