Throughout his research career Pappenheimer has retained a keen interest in infectious disease. In particular, the diphtheria bacillus has fascinated him. This microscopic organism produces one of the most potent poisons known in biology. The toxin is, in fact, so powerful that a few molecules of it suffice to kill a cell. An easily made by product of the toxin, diphtheria toxoid, is harmless and serves as an excellent immunizing agent. With the virtually universal immunization of children in Europe and the United States, diphtheria has been "licked" in the medical sense. But it still provides many challenging biological questions...
...cytochrome synthesis would produce readily detectable effects. The Cecropia silk worm satisfied the requirement. During both the caterpillar phase and the period of adult development Cecropia produces substantial quantities of cytochromes. In the dormant pupa stage, though, the enzymes occur in only trace amounts. By showing that resistance to diphtheria toxin in the pupa stage is much greater than during other phases, Pappenheimer furnished compelling evidence for his theory...
...year-olds, and in the second, among one-and two-year-olds. Now it is worst among the one-to three-year-olds. Bowing to the statistics, the Public Health Service has recommended that doctors begin polio shots for youngsters two to three months old along with vaccine for diphtheria, tetanus and whooping cough...
...DIPHTHERIA. Steadily on the decline since 1946, the disease struck 23% fewer victims last year than the year before. Of the 1,211 total, Michigan accounted for 100 in December alone...
...Twirling Dials, $40. The tariff was stiffer in Bryan, where Mrs. Keene complained of headache and stomachache. There, Naturopath Charles Moore told her she still had diphtheria toxins in her throat from a childhood attack, that she also had colitis; her spleen, pancreas and liver were not working right; she was anemic and her pulse was too slow. He sold her special foods for $9, and for the examination (done by twiddling the dials of a machine that looked like a short-wave radio) he charged...
