Cholecystokinin influences pancreatic trophism following total gastrectomy in rats

摘要

In rats, total gastrectomy (TG) has been shown to induce pancreatic hyperplasia and increased tissue concentrations of pancreatic trypsin and amylase, whereas lipase concentration was decreased. We performed total gastrectomy with the additional insertion of a duodenal tube in 17 rats. A central venous catheter was placed after 3 wk. The control groups consisted of sham-operated rats with a gastrotomy plus duodenal tube and a group of rats with only a duodenal tube.
