...member of the University of Rochester faculty for 18 years, Berry has conducted extensive research in birds, animals, and man related to such diseases as psittacosis (parrot fever), yellow fever, and encephalitis (inflammation of the brain). He has also studied the relationships of certain viruses to cancer, and has been especially concerned with the mechanisms of virus infections...
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...
Other highlights reported from the continuing war against cancer: A virus may be one of the causes of cancer, researchers have long suspected. In 1936, a viruslike "milk factor" was discovered in mice. Last week a five-man Columbia University team reported that it had succeeded, after twelve years of work, in isolating, identifying and photographing (in an electron microscope) a virus that causes breast cancer in mice. The virus is so powerful that an injection of eight one-thousandths of a gamma (a gamma is one-thousandth of a milligram) produced cancer even in male mice. Next step, already...
...York Post raised a hue & cry against the dangers of DDT, with a series of articles called "DDT and You." Deutsch based his original assertions on research by Manhattan's Dr. Morton Biskind, printed in The American Journal of Digestive Diseases. Deutsch contended that the mysterious ailment called virus X, which rose to epidemic proportions in Los Angeles about two years ago, has the same symptoms as DDT poisoning and may be traced to indiscriminate use of the chemical. X disease, which has attacked herds of cattle in 37 states, also looks suspiciously like DDT poisoning. What...
...articles had prompted health officials to some replies and explanations. The main theme of the experts: there is no cause for alarm. No dangerously contaminated samples of milk have yet been found. Further, said a U.S. Public Health official: "Statements that DDT is responsible for causing the so-called virus X disease of man and X disease of cattle are totally without foundation. Both of these diseases were recognized before the utilization of DDT as an insecticide." Nonetheless, one Department of Agriculture warning was repeated: "DDT should not be used for insect control on dairy cows . . . Presence of the chemical...
