...last reagent of its kind on earth, you can't afford to lose it," Fineberg says...
...virology lab got its usual load of new specimens to analyze, including one from a two-year-old boy admitted the day before to Queen Mary Hospital. Her lab applied the ordinary WHO reagents for H3 and H1, but just as in May, got no reaction. This time Lim tried an H5 reagent supplied by the CDC. And got a positive reading...
With a whirring of gears, a set of spools turns, unrolling a sheet of printing paper against the negative. The technicians meanwhile spread the patented Polaroid chemical reagent-a viscous mixture they call "goo"-onto both sheets simultaneously. After passing between a pair of rollers, the sandwich of photographic papers is raised, by rope and pulley, toward the ceiling. Then the sandwich is lowered to the floor, and the negative is lifted off, revealing the huge full-color print. "It's nothing but a small Polaroid process made larger," says Technician Peter Bass...
...that a single nine-banded armadillo that died recently at Gulf yielded some 300 trillion leprosy bacilli-good news for medical researchers who have been searching for ways to cultivate the bacteria for laboratory studies. Doctors will also be able to use the infected tissue to make a diagnostic reagent called lepromin, which is used to predict the severity of a leprosy patient's disease. The single New Iberia animal has yielded enough of the chemical to perform 15 million tests-about as many as there are leprosy patients in the world...
...pathologists and hematologists compared his blood type and cells with Blaiberg's. By a 12-to-l chance, both had type B, Rh-positive. Droplets of serum containing Haupt's white cells were pipetted onto dime-size disks in a plastic tray, each disk containing a cell-reagent preparation. The intensity of the reactions on different disks was noted, and compared with those already obtained from Blaiberg's cells. The cells, concluded Pathologist Martinus C. Botha, were a fairly good match. Not identical-that is impossible-but similar enough to suggest that Blaiberg's rejection mechanism...
