| Research Abstract |
In pancreaticobiliary maljunction, reflux of pancreatic juice causes many conditions including inflammation, and may be relate to carcinogenesis. However, mechanism is not well known. This time, we administered DBTC torats and made the model of pancreaticobiliary maljunction. Single dose of 8mg/kg DBTC caused biliary stasis and papillary growth of epithelium, and we confirmed high expression of Ki-67, COX2 and HDAC by immunohistochemistry. However, papillary growth was recovered 4 weeks after administration. As Rats died by frequent dose of DBTC and we could not observe in long time, we try to make mouse model of pancreaticobiliary maljunction by surgical technique.
