  • Title: [Effects of protamine on blood lipoproteins in the early period of hypercholesterolemia in rabbits].

    Journal: Biull Eksp Biol Med; 1990 Jul; 110(7):40-2. PubMed ID: 2224096.
    Abstract:
    The content of protein, cholesterol and triglycerides in chylomicrons and different classes of blood serum lipoproteins was studied under protamine action in early (1 month) hypercholesterolemia. Except the low density lipoproteins the amount of triglycerides in the particles studied was practically unchanged. The content of proteins in all classes of lipoproteins was greatly increased and this may indicate that protamine activates the blood lipoprotein system. The enrichment of lipoproteins with cholesterol may be taken as being a result of protamine action in early hypercholesterolemia. The peculiar feature in the effect of protamine on mentioned lipoprotein components was that the protein/cholesterol ratio didn't change in chylomicrons, decreased in very low density lipoproteins and low density lipoproteins and increased in high density lipoproteins as compared with controls.
