...Cole, all of the Washington University Medical School, St. Louis, began research to make possible visualization of the gallbladder by use of the Xray. They found that certain salts injected into the body are eliminated through the bile, which is stored in the gallbladder. They knew that iodin and bromin salts are opaque to the Roentgen ray. They secured a combination of these salts and obtained X-ray pictures of the abdomen in which the gallbladder, previously invisible because of soft tissue, appeared almost as clearly as did the bones themselves. Stones in the gallbladder were localized easily...
...George W. Crile, Cleveland, discussed the present standing of knowledge of the thyroid gland. The abnormal conditions for which physicians are called include increased secretion from the gland, lessened secretion and abnormal growths. In the case of lessened secretion physicians treat the condition by giving small doses of iodin during youth or during periods such as pregnancy when the gland may be heavily drawn on; also by the giving of doses of thyroid extract or of thyroxin. Dr. Crile pointed out that iodin must be given with great caution to grown persons who may have a tendency to thyroid tumor...
Evidence has been accumulating to establish definitely the fact that goitre is due to a deficiency of iodin in the food and water taken into the body. Dr. J. F. McClendon, Professor of Physiology in the University of Minnesota, and Joseph C. Hathaway have completed an analysis of food found in goitrous and non-goitrous regions. In regions where goitre did not prevail the iodin content of the food may be as much as 100% higher than in goitrous regions. The investigators also analyzed the water from various cities in the U. S. It was found that the water with...
...districts with an extremely large proportion of goitres, noted that little had been said relative to babies born with goitre. In his own practice during one year, twelve babies were born with this condition. The goitre of the child is apparently caused by a deficiency of iodin in the diet of the mother. It may be prevented by giving the pregnant woman small doses of iodin regularly during the prenatal period...
Much has been said of the giving of small quantities of iodin regularly to growing children in districts where goiter is frequent, and the accumulated scientific evidence seems to show that the method is efficient. Donald K. Tressler and A. W. Wells of the U. S. Bureau of Fisheries have recently made a study of the amount of iodin contained in various food substances. Iodin is found in all fish and fishery products, mollusks and crustaceans; marine fishes contain more iodin than fresh water fishes. Oysters, clams and lobsters contain 200 times as much iodin as beef steak or milk...
