title: Possible neoplastic effects of acrylamide on rat exocrine pancreas.
abstract: We investigated whether the acrylamide formed during cooking carbohydrate-rich foods at high temperatures causes neoplastic changes in rat pancreas. Azaserine, which is an amino acid derivative that has the ability to initiate neoplastic changes in rat pancreas, was injected into 14-day-old male rats once a week for three weeks. Acrylamide was given to both azaserine-injected and non-injected rats at doses of 5 and 10 mg/kg/day in drinking water for 16 weeks after which tissue slides were prepared from the pancreata. Pancreas weights and body weights of rats treated with azaserine and acrylamide together increased significantly compared to the other groups. Moreover, the size, average diameter and volume of atypical acinar cell foci that developed in the pancreata of rats treated with azaserine and acrylamide together increased significantly compared to rats treated with either azaserine or acrylamide alone and control groups. Atypical acinar cell adenoma or adenocarcinoma was not observed in the pancreata of rats in any group.
