o D 3 0 FOURTEEN MEDFORD (OREGON) MAIL TRIBUNE Monday, August 8, 1955 Science Finds Easier Way To Make Salk Polio Vaccine Safer By DELOS SMITH United Pri Scianc Editor New York (U P.) Science has come up with a new and easier way of making the Salk anti-polio vaccine safe and surer. It may speed the perfection of vaccines against other virus caused diseases. By the new way, live viruses can be all but completely separ ated from the substances in which they are grown. What you get are concentrations of viruses which contain just about noth ing else. The three scientists who per . formed this amazing feat made a kind of emergency report to the American Association for the Advancement of Science. They wanted to get an outline of the method to other scientists, especially those involved in mak ing the Salk vaccine, , as quickly as they could. Has 'Many Applications' These scientists Joseph Smolens, Lewis Coriell and A. Green, of the School of Medi cfie, University of Pennsylvania said the method's "many ap plications" were "obvious." For one thing, it can be used as a comparatively simple "safe ty test" of the Salk vaccine. For another, it can greatly simplify the "killing" or deactivation of the live polio viruses used in the vaccine. For still another, it can assure the "antigenic stab ility" of the vaccine in other words, any given "shot" of vac cine would be just as effective as any other "shot" in stimulat ing blood chemistry into produc ing anti-bodies against polio vir uses. Their feat was based upon the discovery of Dr. E. J. Cohn of Harvard that heavy metals will assist in separating various com ponents of blood plasma. The Cohn techniques had been used to concentrate and purify influ enza viruses. Smolens, Greene and Coriell adapted them to pol io viruses. Method Utilizes Zinc To monkey tissue cells in a nutrient bath in which polio vir uses had grown, they added zinc lactate. The temperature, degree of acidity, and the proportion of zinc had to be regulated in order to get the maximum af finity of viruses for zinc. Vir uses and zinc "fell out" of the solution and were separated from it by whirling. Then they had a pure com pound of polio viruses and zinc lactate. The latter either was washed out or removed chemic ally. Repeated analysis showed that either method was remark ably effective that less than two parts zinc remained for each 1,000,000 parts of viruses. Analysis of the solution, after the viruses and zinc were whirl ed out of it, showed that it con tained 0.1 per cent viruses, that meant that 99.9 per cent of the viruses it contained originally had been removed. Further tests showed that the viruses had not been changed or affected. TRAIN DERAILED Rugby, England (UP.)

Mindszenly Slaying In Hungarian Castle Vienna U.R) Josef Cardinal Mindszenty, Roman Catholic pri mate of Communist Hungary, is staying at a castle near the city of Pecs in southern Hungary, church officials said today. The government last month announced the release from prison of the cardinal after more than six years imprison ment.
