Abstract:
Objective To establish a pancreatic cancer model in Sprague Dawley(SD) rats,and to study the distribution and the counts of myofibroblast(MF) in pancreatic cancer and non-cancerous pancreatic tissues.MethodsDirectly implanted DMBA into pancreas parenchyma of SD rats and established TSA intervening group and control group. The carcinogenesis of rats executed within 3~5 months were inspected by HE stain and microscopy for pathomorphological changes.Myofibroblast(MF) was stained by Heidenains method. Results (1)The prevalence of pancreatic cancer in experimental group was 48.7%(18/37), including 17 pancreatic ductal adenocarcinoma and 1 fibrosarcoma. The prevalence of pancreatic cancer in intervering group was 33.3%(12/36), including 11 pancreatic ductal adenocarcinoma and 1 fibrosarcoma. The maximal diameters of tumor mass of experimental group was higher than that of intervering group (P
