...eggs, fertilized in a finger bowl with five drops of sand-dollar sperm, were put into the individual compartments of a plastic ice-cube tray (300 eggs to a "cube"), and kept in sea water. As they grew, Dr. Karnofsky added various concentrations of drugs known to be useful in treating cancer and noted the kind and degree of their effects. Against this base line, he could test hitherto untried substances and estimate their probable usefulness against cancer. The method will not replace the testing of drugs in animals, Dr. Karnofsky told the American Association for Cancer Research, but will...
...made surgically pure by being pumped through a 7-ft. cube housing 72 small cylinders, each containing an ultraviolet arc. The cylinders were designed so that every passing air particle swirled within 3 in. of a germ-killing arc light. Since ultraviolet rays kill germs more effectively at close range-their germicidal effect is proportionate to the square root of the distance-a microbe had only 1/256th as much chance of surviving a trip through the cylinders as it would have under an ultraviolet lamp hanging 4 ft. above the operating table...
