Title: Inhibitory effect of sodium salicylate on ADP-induced platelet aggregation and on 45Ca2+ uptake into platelets. Author: Irino O, Saitoh K, Ohkubo K, Hashimoto S. Journal: Thromb Res; 1985 Aug 01; 39(3):369-77. PubMed ID: 2996170. Abstract: The effects of sodium salicylate (SS) on ADP-induced platelet aggregation and on a metabolism of calcium in platelets were studied, using gel-filtrated platelets (GFP). SS inhibited dose-responsively ADP-induced aggregation in the presence of fibrinogen and Ca2+. It was found that extracellular 45Ca2+ was rapidly taken up into platelets after stimulation by ADP, while SS significantly inhibited this activity. On the other hand, SS had no effect on platelet aggregation induced by 0.11-1.0 microM ionophore A23187. Therefore, it was found that the inhibitory effect of SS on ADP-induced platelet aggregation may be due to the inhibition of the active influx of extracellular Ca2+ into platelets during aggregation.[Abstract] [Full Text] [Related] [New Search]
