...abscesses and scars. Victims develop a hacking cough, run a low fever. Lipid or oil pneumonia is difficult to diagnose, for few physicians know much about it, and different oils cause different symptoms. In old people oil pneumonia is sometimes mistaken for cancer of the lung. Pneumonia caused by bacteria can be successfully combated with serums and sulfapyridine or sulfathiazole; for lipid pneumonia there is no treatment. At present, said Dr. Cannon, oil pneumonia is recognized chiefly at autopsy...
Pneumonia is an inflammation of the lungs. It can be caused by any one of 33 types of pneumococci, by many other bacteria, or by viruses. Last fortnight, in the Journal of the American Medical Association, Dr. Paul Roberts Cannon of the University of Chicago warned physicians of another, "manmade" form of the disease: oil pneumonia...
...Cannon believes that such oils may carry bacteria and viruses from the nose into the lungs. But cod-liver oil, though it is "extremely injurious to pulmonary tissues," is often essential for a child's diet. It should never be given to struggling children, never be fed to infants while they are lying on their backs. Safe procedure: give a few drops at a time, or use vitamin concentrates...
Nobody knows exactly why teeth decay. Dentists generally agree on one clue to the mystery: certain acid-forming bacteria, such as lactobacilli, grow on tooth enamel, ferment crumbs of sweet and starchy foods which lodge in tooth crevices. The acid thus formed dissolves calcium in the teeth, causes cavities...
Like sweat and urine, saliva contains urea, a nitrogen compound. Dr. Stephan found that two groups of antagonistic bacteria flourish in saliva: 1) the destructive lactobacilli; 2) harmless germs of the staphylococcus family. By brewing an enzyme called urease. the staphylococci split up urea in the saliva into an ammonium compound, which neutralizes the erosive acid. Dr. Stephan's conclusion: teeth may decay when the saliva does not contain enough urea, or when the staphylococci are sluggish...
