Intestinal absorptive function.
The normal gut is adapted to intermittent feeding with complex macromolecular substrates of low sodium content. The high permeability of the upper small intestine to sodium, together with sodium rich saliva and pancreaticobiliary secretions results in large sodium fluxes into the lumen. These substantial sodium influxes are matched by equally large effluxes from the ileum and proximal colon, wh...
متن کاملDifferences in Intestinal Absorptive Capacity of Chickens for D-Xylose
Background: According to literature, there are differences among different species of animals in respect to absorption of D-xylose. OBJECTIVES: In two experiments, the differences that might exist in absorptive capacity of small intestine for D-xylose, in different types of chicken were tested. METHODS: In experiment one, 2 groups of nine adult layer type males (48 weeks) and females (58 weeks)...
متن کاملEpithelial cell proliferation and intestinal absorptive function during starvation and refeeding in the rat.
1. Intestinal epithelial cell production and intestinal absorption were measured in fed, starved and refed rats. 2. Four days' starvation significantly decreased the crypt cell production rate (CCPR), absorption, small intestinal length and crypt cell population. 3. There was an immediate increase in absorption 1 day after refeeding, which preceded a slower increase in CCPR. The absorption rate...
متن کاملIron absorptive function of neonatal pig intestine.
To define the iron absorptive phase across the intestinal mucosa of neonatal pigs, the final SgFe concentration ratio of serosal to mucosal medium of everted gut sac at 1 hr incubation was measured. With .2 btg carrier iron (ferric citrate with molecular weight of 1,500) per milliliter of both the serosal and mucosal medium, the duodenum transported the iron against the concentration gradient f...
متن کاملImmunocytochemical demonstration of ecto-galactosyltransferase in absorptive intestinal cells
Galactosyltransferase immunoreactive sites were localized in human duodenal enterocytes by the protein A-gold technique on thin sections from low temperature Lowicryl K4M embedded biopsy specimens. Antigenic sites detected with affinity-purified, monospecific antibodies were found at the plasma membrane of absorptive enterocytes with the most intense labeling appearing along the brush border me...
