Quantitative endoscopic ultrasound elastography: an accurate method for the differentiation of solid pancreatic masses.

abstract：BACKGROUND & AIMS:Activated pancreatic stellate cells have recently been implicated in pancreatic fibrogenesis. This study examined the role of pancreatic stellate cells in alcoholic pancreatic fibrosis by determining whether these cells are activated by ethanol itself and, if so, whether such activation is caused by t...
