Platelet adhesion and platelet thrombus formation on subendothelium of human arteries and veins exposed to flowing blood in vitro. A comparison with rabbit aorta. 1979

T B Tschopp, and H R Baumgartner, and K Silberbauer, and H Sinzinger

Subendothelium of blood vessel segments from elderly patients was exposed in a perfusion chamber to citrated blood under arterial blood flow conditions. The resulting platelet adhesion and thrombus formation was assessed morphometrically. The results show that the time course and the extent of platelet adhesion and aggregation were similar to the results obtained previously with subendothelium from rabbit arteries. The extent of surface-induced platelet aggregation was furthermore governed by both the properties of the exposed surface as well as those of the blood perfusate. No significant differences with regard to platelet reactivity were found between veins and arteries and the extent of surface-induced platelet aggregation was rather low.

UI MeSH Term Description Entries
D010973 Platelet Adhesiveness The process whereby PLATELETS adhere to something other than platelets, e.g., COLLAGEN; BASEMENT MEMBRANE; MICROFIBRILS; or other "foreign" surfaces. Adhesiveness, Platelet,Adhesivenesses, Platelet,Platelet Adhesivenesses
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
D011817 Rabbits A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.
