McDermott of New York Hospital-Cornell Medical Center. Reporting on their findings at a Veterans Administration conference in Atlanta last week, Dr. Hinshaw explained that Tibione belongs to a group of chemicals (the thiosemicarbazones) which are new to medicine. It is unrelated to the antibiotic streptomycin - or to para-amino-salicylic acid (P.A.S.), the only other chemical previously known to be effective against tuberculosis...
Professor Williams and his associate, Paul Charles Zamecnik, Harvard associate in medicine, have a serious purpose. They are trying to study the structure of protein, the basic substance of living creatures. Fibroin, the principal constituent of silk, is a protein. Scientists know that it is made of certain amino acid molecules linked together in chains. What they do not know is how the chains are put together. The plan is to find out how the silkworms do it. Professor Williams is injecting mature worms with various amino acids which are made radioactive by carbon 14. After a while the worms...
...instead of shapes. (Low point: a head of Christ with a crown of bona fide barbed-wire thorns and chandelier pendants for tears.) But the abstractions seemed little better: Theodore Roszac's spiny steel Recollection of the Southwest looked no more handsome than a broken bedspring, and Leo Amino's colored plastic Remembrance of Things Past might have been mistaken for a highly original gumdrop display. Such eccentric exhibits made the few conservative examples of academic excellence (including a pair of female nudes by Raymond Puccinelli and Oldtimer William Zorach, both entitled Invocation) look even, finer than they...
After trying "more things than you can shake a stick at," Drs. Atlas and Hottle found that tryptophane (an amino acid) and perchloric acid changed the color of a solution if the virus was present. The color deepened from pinkish brown to dark brown according to the quantity of virus present; if there was no virus, the solution stayed clear. The exact strength of the virus can be fixed by using a spectrophotometer, which measures color by comparing it with a standard. The researchers have been able to make as many as 112 tests a day; normally they...
...Tuberculosis of the intestines is one of the most feared complications of TB of the lungs. The newest hope is eight-year-old PAS (for para-amino-salicylic acid). A highly optimistic report of its use by two Swedish doctors appeared in the Swedish medical journal Laekartidningen. Drs. Bo Carstensen and Stig Sjoelin reported trying PAS on 22 men & women whose chances were "hopeless or dubious" by ordinary methods of treatment. After two to four weeks' treatment (five to 14 grams of PAS a day) all 22 were "completely or almost completely" cured of abdominal symptoms. Pain disappeared completely...
