Abstract:
The increased incidence of pancreatic cancer in the Western world and its grave prognosis has resulted in an urgency for research in this area. Until now the available data on toxicology of the pancreas has been few and fragmentary, scattered throughout the literature. A benchmark volume, Toxicology of the Pancreas pulls together information in this neglected area of toxicological research and highlights fundamental research performed in the last ten years. Leaders in the field discuss important structures, the detoxification and toxification process at the cellular and sub-cellular level, the distribution of phase 1 and phase 2 drug-metabolizing enzymes and their role in pancreatic disease, and the role of diet and toxicants on pancreatic disease. The book also covers the role of altered genes in the integrity of the pancreas and explores comparative toxicology in humans and in the lab species used in testing. Illustrated with histological, electron microscopical, and immunohistochemical formats, this book provides a comprehensive and novel presentation of biological and toxicological data. It stands alone as a reliable resource of information easily accessible to professionals in different disciplines.
