Evaluation of Nialamide on the Coagulation of Blood : Introduction of a New Technic for Measuring Adhesiveness of the Platelets

Nialamide at a single oral dose of about 3 mg./Kg. body weight produced decreased prothrombin activation by rendering the platelets less effective. It also decreased the adhesiveness of the platelets as measured by two different technics. A new technic for measuring the adhesiveness of the platelets has been described. It utilized a principle by which venous blood directly circulated through a column of fine glass beads, after which the platelets were reduced in number.
