...progress is advancing from the lab to the bedside. Factor VIII is now being extracted from human plasma and concentrated about 30 times. It is given by intravenous drip to victims of hemophilia A and von Willebrand's disease when they have crises of massive bleeding. Except in such emergencies, the usual treatment for all the clotting disorders remains a transfusion of fresh whole blood or plasma-not to replace blood that the patient has lost, but to supply the missing clotting factor and thus keep him from losing more...
...only precautionary measure taken by the Administration, so far has been to administer gamma globulin, a blood plasma rich in antibodies, to roommates and other close friends of the four students. Prout said the disease is "not communicable except in very early stages," and spreads only through close personal contact...
...leukemia patients threatened with uncontrollable hemorrhage. A healthy donor gives two pints of blood at a sitting, instead of the usual single pint. But while he is still on the table, high-speed centrifuges separate the platelets. Most of the rest of the blood (red cells, white cells and plasma) is returned to his veins at once. He can continue such donations twice a week for months on end. Al ready available at the N.C.I, in Bethesda, Md., the equipment that separates the platelets for leukemia patients is now being installed in Boston, Philadelphia, Houston and Los Angeles...

...need the most help-engineering professors. They now teach youngsters who will live well past the year 2000, but their own training of two decades ago might almost as well have been in 1900. As recently as 1950, for example, few engineering undergraduates were learning much about relativity, plasma physics or probability theory, all now of major importance. "This tremendous avalanche of technological progress has outstripped them," says Gordon S. Brown, dean of M.I.T.'s engineering school. The professors furiously read technical journals, adds Brown, "but sometimes even the stuff in the journals is two years behind...
