The effect of vitamin E on the adenosine diphosphate induced platelet aggregation.

(1-4). These facts suggest that vitamin E may affect not only on blood coagulation but also on the platelet function. Recently, we found that ƒ¿-tocopheryl ace tate (referred as Toc-ac) inhibited time depen dant decrease of platelet number in the preser ved blood with EDTA-K2 as anticoagulant (5). In the present paper, the effect of Toc ac and ƒ¿-tocopheryl acetophosphate (Toc-acp) on the ADP induced platelet aggregation is reported. MATERIALS AND METHODS
