Eduard De Rober-tis and Francis Otto Schmidt of M.I.T. showed a Toronto convention of the Electron Microscope Society of America some remarkable pictures of the polio virus marching in orderly files along a nerve fiber...
...cells. They found that the fibers were cables made up of many hollow tubes about one-millionth of an inch in diameter. The discovery gave them an idea. The "neuro-tubules" seemed ideally adapted for conducting submicroscopic objects around the body. Perhaps, thought the doctors, they conducted the polio virus on its missions of paralysis and death...
...dramatic results. It cured mice in the early stages of polio; all mice in control groups not getting the drug died. The mice that survived were immune to reinfection. Mice getting a single dose of the drug by mouth did not develop the disease when injected with mouse polio virus...
Phenosulfazole does not act directly on the virus; it seems to affect tissue cells. Without destroying the cells, it changes their physiology to make them unpalatable to the virus...
