摘要:
AbstractWashed human platelets take up arachidonic acid from plasma and incorporate the fatty acid into the major classes of complex lipids. Thrombin impairs net incorporation. It activates endogenous phospholipases which liberate arachidonic acid from phospholipids. As a consequence of thrombin induced aggregation platelets release arachidonic acid intermediates formed by the action of platelet fatty acid cyclooxygenase and by platelet fatty acid lipoxygenase. Cyclooxygenase, but not lipoxygenase, is inhibited by aspirin and indomethicin. Analysis of the pathways of arachidonic acid metabolism may furnish new insight into platelet function and into disorders of primary hemostasis.
