Platelet and Plasma β Thromboglobulin in Mycloproliferative Syndromes and Secondary Thrombocytosis

Abstract
SUMMARY Elevated plasma β thromboglobulin (βtg) and decreased intracellular platelet βtg were found in patients with various myeloproliferative disorders. In secondary thrombocytosis, similar, but less marked changes were found. The abnormalities were increased during episodes of clinical thrombosis and could be suppressed in two‐thirds of cases by aspirin therapy.
