Lipoxygenase inhibitors alter aggregation and adhesiveness of human blood platelets from aspirin-treated patients

The influences of arachidonic acid (AA) and of inhibitors of lipoxygenases (eicosetetraynoic acid-ETYA- and nordihydrogusiaretic acid -NDGA-) on platelet aggregation evoked by collagen or adenosinediphosphate (ADP) as well as platelet adhesiveness to collagen f platelet-rich-plasma (PRP) from aspiri...
