Six such donors were chosen and agreed to provide plasma for leukemic children as required. Donors were subjected to plasmaphieresis as often as the recipient required platelet transfusions but in no case was any donor used more than twice in one week. The donors were studied by determining hematocrit, huenuoglobin, reticulocyte count.5 white blood cell count,6 platelet count4 and total protein (hiuret) concentration at the start of each plasmapheresis, at the end of each procedure and after termination of a period of plasmapheresis. Isohemagglutinin titers7 were performed periodically on the donors’ sera to obtain a practical measurenuent of antibody activity during and after the period of plasmapheresis. In addition, the donors were observed by a physician during the From Institutes the Division of Biologic-s Standards’ and the National of Health, Bethesda, Md.
