Only Setback. For human subjects he chose Ohio's Chillicothe Federal Reformatory. Of 30 volunteers (between the ages of 21 and 30), 26 got a minute droplet of a single strain of polio virus in a teaspoon-ul of milk. The human guinea pigs proved even more susceptible than the chimpanzees to the desired kind of infection. They did not get sick in any apparent way Yet the virus multiplied in their digestive tracts, boosted their antibody levels and was excreted in the stools for one to twelve weeks. It was in this connection Dr. Sabin reported his only...
...handling blood so that all its parts will be as fully utilized as a pig in a packinghouse. Of outstanding importance was the news about red cells. There are 5,000,000 or more of these (each about one four-thousandths in. in diameter) in a cubic-millimeter droplet of blood. It has always been easy to separate them, and recently a method of freezing them in glycerin was perfected. The trick is to get them out of the giycerin undamaged, and that has taken hours of complex effort...
...Enders reported that these test-tube cultures provided a test for the presence of polio and similar viruses, it used to take a monkey a month to confirm a single diagnosis of polio. That was impractical. Many physicians relied (and still do) on a microscopic examination of a droplet of fluid taken by puncture from the patient's spinal column. In normal, healthy fluid, there are few or no cells-not more than eight to the cubic millimeter. In victims of virus diseases like polio there may be 500 cells or more. This is still only a rough & ready...
Facts for the Surgeon. No less important is the mass of red blood cells in the body. Some researchers hold that the "count" of red cells in a droplet of blood is not precise enough. Lawrence now gets a more accurate estimate by tagging the red cells with phosphorus. Then there is the question of blood volume; a surgeon needs to know how much blood may have been lost by injury before he undertakes an amputation, and then how much is lost during the operation. With iodine-131 or phosphorus-32 and a Geiger counter this too, is relatively easy...
...Stefan Zweig's novel, one of those puddle-depth stories that, draining themselves with a sort of literary eye dropper, pretend to contain oceans of ideas. The tedious technique might seem justified if it conveyed vivid people, or even lively situations. Beware of Pity conveys only one droplet of an idea (there are two kinds of pity: good & bad) diluted in gallons of plot...
