Abstract

Acetylsalicylic acid (ASA, aspirin) and sodium salicylate inhibit platelet aggregation induced by collagen, antigen-antibody complexes, gamma globulin-coated particles or thrombin. These compounds suppress the release of platelet constituents, such as adenosine diphosphate (ADP) and serotonin, induced by such stimuli. Since ASA and sodium salicylate do not inhibit ADP-induced platelet aggregation, it appears that their effect on the action of the other stimuli is due to a decrease in the amount of ADP released. The administration of ASA to rabbits (in doses which inhibited collagen-induced platelet aggregation) impaired hemostasis, prolonged platelet survival, and diminished the amount of deposit formed in an extracorporeal shunt.

摘要

乙酰水杨酸(ASA,阿司匹林)和水杨酸钠可抑制由胶原蛋白、抗原 - 抗体复合物、γ球蛋白包被颗粒或凝血酶诱导的血小板聚集。这些化合物可抑制此类刺激诱导的血小板成分释放,如二磷酸腺苷(ADP)和5-羟色胺。由于ASA和水杨酸钠不抑制ADP诱导的血小板聚集,因此它们对其他刺激作用的影响似乎是由于ADP释放量的减少。给兔子服用ASA(剂量足以抑制胶原蛋白诱导的血小板聚集)会损害止血功能,延长血小板存活时间,并减少体外分流中形成的沉积物量。
