...Pontalite" is a new plastic, known chemically as methyl methacrylate polymer, which is as clear as optical glass, only half as heavy as common glass, flexible, non-shattering, able to withstand tensions of over four tons per square inch. It can be sawed, cut, drilled, polished, cast into molds. "The transparency, brilliance, strength and permanence of Pontalite are unusual, and the absence of color permits fabrication into delicate tinted shades."-Dr. Harry Robert Dittmar of E. I. du Pont de Nemours...
...William Russell Levis & Edward Lewis Axelman of Philadelphia call theirs a "Modern Method for Prevention of Postoperative Distention." They depend upon a newly synthesized drug to keep the bowels moving and expelling any gas which may form. The drug: dimethyl-carbamic ester of 3-hydroxyphenyl-trimethyl ammonium methyl-sulphate, a chemical compound which has been telescoped to prostigmin. Drs. Levis & Axelman inject small amounts of prostigmin "at the time of operation or shortly thereafter and continue injections for 24 to 48 hours at four to six hour intervals, or until such time that we feel the condition of the patient...
...Dame. The chemists gave up working on divinylacetylene and concentrated on the more homely mono-vinylacetylene. They treated it with hydrogen chloride and first thing they knew they had a fine pot of chloroprene. Chloroprene differs from rubber's polymer, isoprene, only in that a chlorine atom replaces the methyl group, so after that the going was fairly easy. They had only to polymerize the chloroprene to the right point, and all of them were experienced polymerizers. When they finished they put a piece of their rubber into a bottle of kerosene, left it 72 hr. When it came...
...under Professor Leopold Lichtwitz in the State Hospital at Altona, later under Professor Alexander von Lichtenberg at St. Hedwig Hospital, Berlin. To Altona, Professor Arthur H. Binz, organic chemist, sent an iodine compound which he wanted Professor Lichtwitz to use on cows infected with streptococci. The compound was N-methyl-5-iodo-z-pyridon. Dr. Swick, inquisitive, knew about all the scientific work going on at Altona. With a retentive memory, he knew that Dr. Leonard George Rowntree of the Mayo Clinic in 1923 had illuminated the kidneys & ureters faintly with sodium iodide. The iodine created the opacity. Dr. Swick...
Whenever vision is suddenly affected by a drug there probably is a methyl radical (CH3) involved. Professor Binz's compound had such a methyl radical. Not worried, he offered to synthesize a more tolerable iodine preparation, soon furnished 5-iodo-2-pyridon-N-acetate of sodium, which he calls Uroselectan and U. S. urologists lopax. Injected in the veins it rapidly collects in the kidneys and shows by means of x-rays the shape of those organs and any stones or malformations there or in the ureters (leading from the kidneys to the bladder...
