For long-range work he used giant binoculars mounted on a tripod; with these he could make out the scent gland of the hind leg of a butterfly a quarter of a mile away. "I often wondered," he says, in a sentence of purest Beebe, "what the soaring vultures, looking down, made of this strange creature with great tubular eyes and five legs...
...good example of the interaction of research and clinical study is the work of Rawson's group and of Dr. L. D. Marinelli on the treatment of thyroid cancer with radioactive iodine. Since the thyroid gland eagerly absorbs iodine (which it uses to make a hormone), doctors have hoped that a cancerous thyroid would absorb radioactive iodine 131 in sufficient quantity to kill the unruly cells. Unfortunately, this effort was none too successful. The normal thyroid took up nearly all the iodine. The cancerous thyroid cells, particularly the metastases in distant parts of the body, took up so little...
Elements Absorbed by Gland...
Chiefly concerned are isotopes of elements which the thyroid, especially in cases of toxic goiter, has the property of absorbing and concentrating at the afflicted portion of the gland. This process enables the radiation emitted by the radioactive isotopes to destroy harmful growths. Other elements which do not become concentrated in the body as iodine does, may be used in research on body chemistry, since by their effect on a Geiger counter, their progress through the body may be traced--thus they are termed "tracer elements...
...week later, pain and muscular stiffness had almost disappeared. But improvement ended when the drug was stopped. After varying periods without the drug, the patients were back where they started. Two other patients are being treated, with similar results, with another hormone called ACTH (adrenocorticotropic hormone), a pituitary gland secretion that stimulates the adrenals Oee below...
