Ethanol and platelet intracellular free calcium concentrations.

The effect of 0.8 g kg-1 absolute ethanol orally on platelet intracellular free calcium was assessed in a random order study in 24 normotensive subjects with an isocaloric control. Platelet calcium was measured 90 min and 12 h after treatment by the Quin 2 method. The study had 90% power of detecting a 16.5% change. After 90 min, breath ethanol was 37 +/- 9 micrograms 100 ml-1, blood pressure was unchanged and heart rate rose slightly. Platelet calcium was unchanged by ethanol after 90 min or 12 h.
