...years' experimentation with tissue cultures at the Institute, Dr. Wilton R. Earle transformed normal cells to cancerous cells by treatment with 20-methyl-cholanthrene, a coal-tar chemical. In an effort to determine what takes place in the mutant cells, he now plans to destroy existing cultures and re-outfit his laboratory for a fresh attack on the baffling problem...
Northwestern University Dental School's Dr. Leonard S. Fosdick & co-workers may have found an answer. Reporting in the Journal of Dental Research, the experimenters released some long-awaited data on acid-decreasing synthetic vitamin K (2-methyl-1, 4-napthoquinone). They hit on the idea of spreading it on chewing gum. For the experiment, 55 Northwestern students faithfully chomped vitamin K-coated gum for ten minutes after each meal. Another 45 chewed untreated gum. A third group chewed nothing...
