    Abstract

    The excretion of 2,3-dinor-6-keto prostaglandin F1 alpha, a major urinary metabolite of prostacyclin, and the formation of thromboxane B2, a stable metabolite of thromboxane A2, by platelets stimulated by adenosine diphosphate, were studied in alcoholics, who had been admitted for detoxification. Once prolonged heavy drinking had stopped, platelet count and thromboxane formation, calculated either per 10(7) platelets or per litre of blood, significantly increased (p less than 0.05), while the skin bleeding time and urinary excretion of the metabolite of prostacyclin decreased (p less than 0.05). The balance between prostacyclin and thromboxane therefore seemed to favour the excretion of prostacyclin while it shifted to favour thromboxane formation about a week later.
