...birthday party for a nonagenarian Texas oil millionaire is an unlikely occasion for the announcement of a new treatment that may be effective against some forms of cancer. No less unlikely, as a source of the promising substance, are common colon bacteria that multi ply in sewage and often result in the contamination and closing of beaches. Yet both these elements were present last week in the excitement over a procedure that has given signs of success in the case of just one cancer parent...
...scarcity. If all Texas were turned into a giant guinea-pig farm, the yield would suffice for only a few patients. The break came in 1963, when researchers at the University of Delaware described an immensely complicated process for extracting the enzyme from colon bacilli, Escherichia coli. These bacteria were already being grown in vats to provide other substances used by biochemists, and New Jersey's Worthington Biochemical Corp, set about extracting L-asparaginase from them. It takes pounds of the microscopic bacteria, and would cost close to $15,000, to produce enough L-asparaginase for a month...
Others included Dr. Walter Gilbert, associate professor of Biophysics, genetic control mechanisms in bacteria and viruses; Dr. Frederick A. Olagson, professor of Education and Philosophy - a study of rational explanation in history; Dr. Thomas F. Pettigrew, associate professor of Social Psychology -- a study of the consequences of varying racial compositions in public schools...
...particles of foreign antigen (antibody-triggering substances) are numerous enough. In the medical equivalent of a massive military diversion, doctors try to overload the immune mechanism temporarily by flooding it with antigen particles. By coincidence, an antigen sufficiently similar to the human type is in some streptococci. So these bacteria, usually rated as harmful, are being mass-produced in a program backed by the National Institute of Allergy and Infectious Diseases. The antigen, chemically removed from its microscopic bacterial source, is being distributed to investigating doctors...
...patient was a man of 20 whose heart had been failing for three months. Under study by special microscope techniques at The Kennedy Institute, the muscle specimens were found to contain particles that could not be identified. The one certain thing about them was that they were neither bacteria nor true viruses. From a second patient's heart, the researchers got samples of particles that seemed to be in four or five successive phases of a life cycle...
