Abstract
Summary
The phospholipid partition (lecithin, cephalin and sphingomyelin) of hemophilic plasma revealed no lack of the clot-aiding phospholipid cephalin.
A tested technic showed only minute traces of “free” phospholipid in normal and hemophilic plasma. Measurable amounts of uncombined cephalin and other phospholipids were found, however, in lipemic plasmas. Attempts to liberate cephalin by tryptic digestion of plasma were unsuccessful. Added cephalin combined with the plasma proteins to a large extent, except in lipemias.
The lysis of platelets in the presence of calcium (yielding an active thromboplastic solution) gave lysates containing little or no phospholipid, free or combined.
