title: [Arachidonic acid metabolism affected by cellular interactions regulating leukocyte adherence].
abstract: Increased leukocyte adherence to endothelium is recognized to be the first step following the development of unstable angina and cerebrovascular disease. In this paper, the methods to determine leukocyte adherence and the conditions which influence the result of the assay are discussed. We administered aspirin, TxA2 synthetase inhibitor or TxA2 receptor antagonist to healthy volunteers. Leukocyte adherence was inhibited following the administration of these antiplatelet agents. The effect on leukocytes may prevent thrombosis formation. Although the role of the leukocyte adherence in the pathogenesis of thrombosis has not been fully elucidated. Several forms of stimuli may cause expression of adhesive glycoproteins, which have a RGD sequence, on the surface of leukocyte and thus lead to thrombotic formation.
