title: [Age and biosynthesis and breakdown of thrombocyte proteins].
abstract: Platelet protein biosynthesis and catabolism in adult and one-month-old rabbits was studied with lysine-14C in vivo. Free radiolysine-14C failed to pass through the membrane of the circulating blood platelets, and its appearance within the platelets was possible only at the stage of platelet production. Platelet protein synthesis in one-month-old rabbits was shown to be slower than that of adults. The half-life period of platelet protein in adults averaged 2 days and in one-month-old rabbits-3 days. Slowing down the platelet protein circulation was noted at the early postnatal ontogenesis.
