Tests Without Animals:
The Cosmetic, Toiletry, and Fragrance Association, Washington, DC, which provided a three-year, $1 million grant in 1981 to establish the Johns Hopkins Center for Alternatives to Animal Testing, Baltimore (JAMA [MEDICAL NEWS] 1981;246:2013-2014 and 1982;247:1389), has awarded the center an additional two-year grant, totaling $700,000.Alan M. Goldberg, PhD, center director, says 22 studies are under way at Hopkins and other institutions in an effort to replace use of live animals in some product safety testing. Among other approaches, researchers are impregnating filter paper with fat molecules to simulate the absorptive properties of human skin, studying fibroblast response to irritating chemicals, and attempting to culture cells that develop in ways more nearly resembling the complex structure of human skin.—P.
