One More Clue
In the endless search for a criminal substance which can be provedguilty of causing the explosive growth of cancer cells, suspicion hassettled on an enzyme, hyaluronidase, already known to be a "spreadingfactor." Last week a slim, blonde, 24-year-old graduate student at theUniversity of Wyoming announced that she had picked up another jot ofevidence against hyaluronidase: it is found in abnormally large amountsof sarcoma in mice —a disease muchlike human sarcoma.
Mrs. Rosalie Reynolds did the work for her Master of Science degree. Itwas a hard job, because hyaluronidase is an elusive substance that hasnever been isolated in pure form. Mrs. Reynolds could find none intissue taken from healthy mice. She induced cancer in 50 mice andproduced uniformly heavy concentrations of the enzyme. The percentagewas equally high regardless of the cancer's size or the substance usedto produce it.
Mrs. Reynolds' evidence was not strong enough to convict hyaluronidase.But it was enough to touch off more inquiries in the century's biggestpiece of science detection.
