:i;:v .'i, *uly 18, 1955 Dr. Robert Alan Franklyn 7851 Sunset Boulevard Hollywood k6, California Dear Dr. Franklyn: Your letter of June thirtieth to our Bakelite Company has been referred to me for answering. We do not have or manufacture a silicone sheeting, and we do not know of a nontoxlc vinyl film as far as implantation in human tissue Is concerned. We would refer you to Dr. B. S. Oppenheimer's most reoent article, "Further 8tudles of Polymers as Carcinogenic Agents in Animals," which appeared in CANCER RESEARCH, Volume 15, pages 333-to, June, 1955* We have followed Dr. Oppen heimer's work quite carefully and, therefore, question the safety of implanting such films in humans. Very truly yours. MEDICAL DIRECTOR INDUSTRIAL MEDICAL AND TOXICOLOGY DEPARTMENT Thomas W. Male, M. D. J1 r.. &; UCC 063351
