title: [Effect of continuous enteral feeding on pancreas exocrin function in rats].
abstract: The aim of this study was to examine the effects of continuous enteral feeding (CEF) on the exocrine pancreas in rats. Eight male Wistar rats were intrajejunally cannulated and CEF was started on postoperative day 6. In 10 control animals, laparotomy was followed by intragastric feeding (GF) with the same nutriment (Osmolite, Abbott, 254 mosm/l) from postoperative day 6. The daily discharge was 24 kcal in both groups. After five days of feeding, the pancreas was removed, its weight and its protein, DNA, trypsin and lipase contents were determined. The results revealed no significant difference in body weight loss between the two groups of animals, whereas the pancreas weight/body weight ratio was lower (p < 0.01) in the CEF group. The pancreatic protein, DNA, trypsin and lipase contents were decreased (p < 0.01) after CEF as compared with the values for the GF group.
