When the doctors have a patient with a gangrenous foot or strangulated hernia (protruding loop of gut), they wheel him into an operating room, inject fluorescein, a reddish dye, into the vein of his arm. Then they darken the room, shine an ultraviolet lamp on the gangrenous area. The dye should make a circuit of the patient's blood stream in 20 seconds. If the gut or foot is still alive and receiving fresh blood, it will glow yellow green. Then it is safe to tuck the gut back in place, or stimulate circulation...
Occupational Cancers, which are caused by external environmental agents such as X rays, radium rays, ultraviolet rays, certain complex tar and benzine compounds, hundreds of other carcinogenic (cancer-causing) chemicals. Farmers and sailors may develop skin cancer through long exposure to the ultraviolet rays of sunlight. Cotton spinners in Britain, who are constantly exposed to the carcinogenic mineral oil used in lubricating the spindles, may develop "mule spinners' cancer" of the scrotum. Obviously, said Dr. Cramer, occupational cancer is a "preventable disease." Social Cancers, an expression coined by Dr. Cramer, which include cancers of the esophagus, stomach, upper digestive...
Most of the department's work, however, deals with the less spectacular, if more exacting, work of restoring masterpieces as nearly as possible to their original condition. Where the original work of the artist has been painted over, these reworkings are detected by X-ray, ultraviolet, and infra-red rays in Alan Burrough's Department of X-Ray and are removed and the blank spaces carefully filled in to resemble the original. Actual paint, however, is never retouched or covered with new work. Perhaps the most ticklish job of this type was done in 1923, although not by the Fogg...
...demise of a technical "bug" that has been lurking in the luminescent tubes: the unpredictable "lumen slump" (blackened end-bands, dark streaks and splotches) that afflicts many lamps. Cox's bug killer: a technique for dosing each lamp with the exact amount of mercury needed for adequate ultraviolet radiation...
...Because U.S. chickens consume more vitamin D than the U.S. citizenry, Du Pont has developed a synthetic product to replace the cod-liver oil formerly imported and fed to poultry. Made from sterols (solid alcohols) extracted from animal fats and irradiated with ultraviolet light, it is conveniently dry rather than gooey, like fish oils. Poultrymen last year spent thousands of dollars for vitamin D products to insure strong-shelled eggs, high hatching rates, low mortality...
