...With Oxygen. Drs. Harold Atkins and William Seaman of New York's Colum bia-Presbyterian Medical Center told of progress toward licking a basic problem-radiosensitivity. Since Wilhelm Roentgen discovered X rays, in 1895, radiotherapists have been trying to get radiation to destroy diseased tissue while letting healthy nearby tissue survive...
First at London's St. Thomas's Hospital, and lately at Columbia-Presbyterian, plain oxygen has proved to be a useful ally toward this goal. Cells are more easily destroyed if they have a large supply of oxygen, but tumor cells are frequently oxygen-starved; they grow so rapidly that they outstrip their blood supply. Radiotherapists speculated that they might make up the deficiency by putting the patient in a chamber where he could breathe oxygen at a pressure four times that of the atmosphere. A high concentration of oxygen could then be carried in the bloodstream...
...practice, Drs. Atkins and Seaman and others on the Columbia-Presbyterian team, pick patients with advanced cancer to treat with oxygen and radiation. According to a carefully devised procedure, such a patient gets an anesthetic injected into his veins, and a rubber hose is threaded down his windpipe so that he will not choke while asleep. His eardrums are pricked so that oxygen pressure will not perforate them. Monitoring devices, including a microphone that allows the anesthesiologist to listen to respiration, are attached to the body. The patient is put on a stretcher that is placed in the oxygen chamber...
...earlier failures. But last week's Atlas was beefed up for its job, and it performed perfectly; the MA4 accelerated surely into its planned orbit. Strapped in the capsule instead of a man sat an oblong box that performed most of an astronaut's functions: it consumed oxygen, excreted carbon dioxide and water vapor, and it also talked-feeding the recorded voice of NASA Communications Engineer Howard Kyle into a microphone to test the Mercury communication system. Out of a porthole and periscope peered two cameras. Special instruments recorded the assorted stimuli that would have assaulted a human...
...Conference. NASA officials reported that almost everything on the capsule had worked perfectly. One electrical part (an alternator) had misbehaved, but its functions were taken over by a backup duplicate. The oxygen system leaked a little, but not enough to matter. The "man" on board survived the trip, exactly as a human would have, but since he was only a simulated astronaut, he could not hold a press conference...
