Current Issues in Toxicology The Selection of Doses in Chronic Toxicity/Carcinogenicity Studies: Age-Associated (Geriatric) Pathology: Its Impact on , (Paperback)

The International Life Sciences Institute (ILSI) is a scientific foundation which addresses critical health and safety issues of national and international concern. ILSI promotes international cooperation by providing the mechanism for sci- entists from government, industry and universities to work together on co- operative programs to generate and disseminate scientific data. The members and trustees of the Institute believe that questions regarding health and safety are best resolved when scientists can examine and discuss issues, as an in- dependent body, separate from the political pressures of individual countries and the economic concerns of individual companies. Frequently, meaningful assessment of the risk of a test substance is hindered by the inherent inconsistencies in the system. The development and refinement of methods and systems to evalute the safety of chemicals have evolved in a rapid and largely unplanned fashion. Attempts to improve the system have largely been directed toward broad general concerns, with little attention being given to specific problems or issues. A failure to resolve these problems has frequently resulted in increased testing costs and complications in the assessment and extrapolation of the results. In response to these difficulties, ILSI has assembled highly qualified and renowned scientists from research institutes, universities, government and in- dustry, with relevant scientific knowledge and expertise regarding the issues that complicate risk assessment procedures.
