摘要

AIM: To study the inhibitory effects of copper- aspirin complex (CuAsp) on platelet aggregation. METHODS: With adenosine diphosphate the effects of CuAsp on platelet aggregation in vitro or in vivo were investigated. Radioimmunoassay and fluoro- photometry were used to measure thromboxane B_2 (TXB_2) generation from platelets, the levels of TXB_2 and of 6-keto-PGF_1a, in plasma and the platelet serotonin release reaction. RESULTS: In vitro, CuAsp inhibited arachidonic acid (AA)-induced aggregation (IC_50 = 17 μmol·L~-1, 95/100 confidence limits 9 - 33 μmol·L~-1), the release of 5-HT (IC_50 = 19μmol·L~-1, 95/100 confidence limits: 10 -30 μmol·L~-1), and TXB_2 generation from platelets (P<0.05).
