Whole-protein-based enteral formula stimulates intestinal ornithine decarboxylase activity more than single amino acids but does no affect mucosal adenosine triphosphate content in early postsurgical refeeding
|
ABSTRACT. Background: To restore intestinal integrity after starvation and trauma, luminal nutrients are essential. Specific nutrients such as glutamine support mucosal proliferation and energy metabolism. The aim of this study was to compare effects of enteral formula vs specific amino acids on ornithine decarboxylase (ODC) activity and adenine nucleotide metabolism in jejunal mucosa. Methods: Male Wistar rats (240 to 280 g) were starved for 48 hours and subjected to intestinal transection, gastrotomy, and jejunal instillation of 5-mL nutrient solution. In the first experiment, standard ...
