[Lipid peroxidation upon the use of omega-3 polyunsaturated fatty acids in the treatment of hypertension and ischemic heart disease].

Anti-atherosclerotic diet containing 10 or 20 g of ichthyenic oil, used for treatment of 29 patients with cardiovascular diseases, caused an increase in content of polyunsaturated omega 3 fatty acids species in the patients erythrocyte membranes; this pattern may be used as a sensitive criterion of evaluation of the diet fatty component effect. Despite an increase of oxidation potential substrates in tissues, elevation of malonyl dialdehyde in blood plasma and hemolysis of erythrocytes in presence of H2O2 were not observed. This suggests absence of lipid peroxidation induction in adequate consumption of antioxidants.
