Summary
This publication describes the results obtained by treatment of haemophiliacs with
factor VIII preparations isolated from Cohn fraction I by use of tannic acid, FI-O-Ta.
The authors stress the rapidity of the disappearance of factor VIII after injection.
Transfusions are generally well tolerated. One reaction of the pyrogen type has been
observed and also a case of activation of the fibrinolytic system.
A second purification method by means of chromatography on DEAE-cellulose is described.
