| Research Abstract |
SULFATIDES (GALACTOSYLCERAMIDE I^3-SULFATE), WHICH ARE FOUND IN SERUM LIPOPROTEINS OF VARIOUS MAMMALS,EFFECTIVELY INCREASED PROTHROMBIN TIME (ANTICOAGULANT EFFECT) AND ALSO EFFECTIVELY PROLONGED BLEEDING TIME (ANTI-PLATELET EFFECT). WHEN EQUAL VOLUMES OF A HOMOGENEOUS MICELLAR SOLUTION OF SULFATIDE AND FIBRINOGEN IN PHOSPHATE BUFFERED SALINE WERE MIXED,AN INSOLUBLE COMPLEX PRECIPITATED.ANALYSIS OF THE PRECIPITATED COMPLEX SHOWED THAT THE MOLAR RATIO OF SULFATIDE TO FIBRINOGEN WAS ABOUT 400 : 1. THESE RESULTS INDICATE THAT THE SULFATIDE MICELLEBINDS TIGHTLY TO FIBRINOGEN AND THEREBY INTERFERES WITH BOTH FIBRIN GEL FORMATION (ANTICOAGULANT ACTIVITY) AND PLATELET FUNCTION.
