[Effect of the total replacement of fats in the diet with a phospholipid concentrate on oxidative phosphorylation in liver mitochondria and the lipid composition of the plasma and liver in rats].

Experimental rats were given rations with 100% substitution of fats for phospholipid concentrate, during 1 and 3 months. It was found that such rations produced hypolipidemic and hypocholesterolemic effects, that were most pronounced at the end of the experiment. A control ration with sunflower oil containing high levels of unsaturated fatty acids induced accumulation of lipid peroxides in the hepatic tissue and blood plasma of the animals fed with the ration during 3 months. The ration containing the phospholipid concentrate did not produce such an effect. The data obtained have evidenced a positive influence of the phospholipid concentrate on the lipid metabolism parameters studied.
