Died. Dr. Charles Armstrong, 80, an Ohio-born research physician for the National Institute of Health who, in 1939, cultured a strain of human polio virus that could paralyze mice, thus giving scientists a low-cost laboratory animal, a breakthrough that inaugurated 16 years of intense research, climaxing in development of the Salk vaccine; of uremia; in Chevy Chase...
...Asparaginase. The story of L-asparaginase traces back to a 1953 observation by Cornell University's Dr. John G. Kidd that serum from normal, healthy guinea pigs killed some-but by no means all-types of cancer in mice, without harming the animals' other tissues. It took Cornell's Dr. John...
...organs. But his red-blood cells were being destroyed as an apparent side effect and treatment had to be stopped. The boy died of his leukemia. The problem of purification remains. Even the presumably safer material extracted from bacteria, in its currently purest form, causes allergic reactions in mice-as it did to some extent in the case of young Frank Hayes...
...testified that they had found bacterial contamination in batches of the vaccine. Dr. Roderick Murray of the U.S. Public Health Service's Division of Biologics Standards said that Rand's report on tests of the toxicity of the vaccine covered only one horse, twelve rabbits and 40 mice. There was evidence that the vaccine had moved across state lines to New York, Idaho, Wisconsin, Washington and Florida without having FDA approval...
...prove that they had really isolated an infectious agent, the researchers had to grow it; they found it would multiply only in a medium containing living heart muscle itself. When the crop was injected into mice, the animals died in much the same way as heart-failure patients. What can the particles be? The investigators can only speculate that they may be a hitherto unknown form of life, with some of the properties of protozoa (such as malaria parasites) and some properties of viruses. If they are right, they may be on the track of other unexplained diseases...
