...basic technique was worked out at the Rockefeller Institute for Medical Research by a team including famed Microbiologist René J. Dubos and Dr. Gardner Middlebrook. Between 5 and 7 cc of blood (less than two teaspoons) are drawn from an arm vein. The serum (amber fluid) is separated from the cells and added to a specially treated preparation containing the red cells of sheep's blood. The mixture is kept at blood heat for two hours and then left at room temperature overnight...
...contents of the test tube are unclotted in the morning, the patient has no active tuberculosis. But if the patient is tuberculous, his blood serum will contain antibodies manufactured in the body to combat the tubercle bacilli. These antibodies will cause the sheep's red blood cells to clot. The extent of the clotting gives a measure of the severity of the disease. Thus, repeated tests can show whether or not a course of treatment is working effectively...
...Sidney Rothbard put the technique to wide practical use at Montefiore Hospital in The Bronx. Last week he reported at a meeting of the New York Tuberculosis and Health Association that on 1,200 serum samples from 950 patients the test was 92.3% accurate. "This test," said he, "gives the doctors a new tool. It should not be thought of as a test to displace the X ray or any other standard method...
...week, for all the forced-draft accomplishments of the years since V-J day, the city and its satellite towns were still grappling with a multiplicity of problems. The prosaic business of supplying new homes with gas, sewage lines and electricity had taken on the breathless urgency of a serum flight to Nome. Under Bowron's administration 50 miles of cast-iron water mains had been laid every month to keep up with the city's mushrooming growth. Los Angeles had built 34 new schools in ten years and still needed "a new one every Monday morning." Though...
Safer Blood. Stockpiling whole blood and plasma is now known to be risky: some recipients get a serious liver disease called homologous serum jaundice. One donor who carries the jaundice virus in his blood might infect a pool given by 5,000 donors. Drs. Frank W. Hartman and George H. Mangun of Detroit's Henry Ford Hospital think they have found a way to sterilize the blood and kill the virus without making the blood harmful or useless. They have used nitrogen mustard, a war gas, and are now experimenting with a chemical called dimethyl sulphate. To prove...
