The morphologic and functional properties of platelets after irradiation with 2500 rads and storage, in first-generation containers, for 48 h in a liquid phase at 20 degrees C with continuous horizontal agitation have been analyzed and compared with a control group of the same platelets which were not irradiated. The preservation technique induced changes in the morphology and aggregation stimulated by ADP and collagen. However, no significant differences were found between the irradiated and non-irradiated groups. Irradiation is not a conditioning factor to add to the hazards of preserving platelets in a liquid phase.

UI MeSH Term Description Entries
D010974 Platelet Aggregation The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS. Aggregation, Platelet
D001792 Blood Platelets Non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. They are mainly involved in blood coagulation. Platelets,Thrombocytes,Blood Platelet,Platelet,Platelet, Blood,Platelets, Blood,Thrombocyte
D001793 Blood Preservation The process by which blood or its components are kept viable outside of the organism from which they are derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).
