STUDIES ON THROMBIN-INDUCED PLATELET AGGLUTINATION* BY RICHARD W. SHERMER, REGINALD G. MASON, ROBERT H. WAGNER,:~ PH.D., A~rD

The mechanisms underlying these platelet changes, often referred to as agglutination and viscous metamorphosis, are poorly understood. Since the early work of Wright and Minot (1), many studies have suggested that thrombin may be involved. Widely divergent con...
