词汇 | dick test |
词源 | Dick test. Like the more famous curies, Drs. George Freder- ick and Gladys H. Dick form a famous husband and wife scien- tific team. In 1923 they isolated the streptococcus that causes scarlet fever. The following year the Dicks devised the test used to determine an individual’s susceptibility to the disease and developed a serum providing immunity. In the Dick test scarlet fever toxins are injected into the arm; if the individual is not immune, the skin reddens around the injection. George Fred- erick Dick (b. 1881) was professor of clinical medicine at Rush Memorial College when he and his wife made their discoveries. He served as chairman of the department of medicine at the University of Chicago Medical School from 1933 to 1945. |
