Experiments have already shown that penicillin attacks certain bacteria more successfully than sulfa drugs do. Unlike sulfa drugs, penicillin's effects are not inhibited by pus and other materials formed in infected wounds. Used in low concentrations in the blood stream, penicillin's action is bacteriostatic, i.e., it prevents bacteria from multiplying and renders them easy prey for white blood corpuscles. Penicillin solutions strong enough to kill bacteria may safely be injected under the skin near a wound or used as a dressing...
...crowd of researchers from the National Exposition of Chemical Industries at Chicago witnessed the demonstrations. They compared photographs already made with the large instrument, revealing unsuspected details in the structure of metals, pigments, powder, oils and in the anatomy of bacteria and viruses. Physicians were especially eager: some expect the conquest of diseases like the common cold, influenza and infantile paralysis, caused by viruses invisible except in the electron microscope...
...little if any more than an electric refrigerator. Westinghouse already has made a two-cell unit selling for $300 that will clean the air in the average six-room home." Savings on cleaning and replacements are substantial; savings on health cannot be figured although the Precipitron catches pollen and bacteria. Not even tobacco smoke, which has the finest particles found in the air (16,000 side by side are no wider than a pinhead), escapes its electrical filter...
...which is a sort of thin glycerine. Results were much better. Then the researchers found that the propylene glycol itself was a potent germicide. One part of glycol in 2,000,000 parts of air would-within a few seconds-kill concentrations of air-suspended pneumococci, streptococci and other bacteria numbering millions to the cubic foot...
...work? Respiratory disease bacteria float about in tiny droplets of water breathed, sneezed and coughed from human beings. The germicidal glycol also floats in infinitesimally small particles. Calculations showed that if droplet had to hit droplet, it would take two to 200 hours for sterilization of sprayed air to take place. Since sterilization took place in seconds, Dr. Robertson concluded that the glycol droplets must give off gas molecules which dissolve in the water droplets and kill the germs within them...
