  • Title: Influence of ageing on sugar and electrolyte transport in rat jejunum and ileum "in vitro".
    Author: Esposito G, Tosco M, Orsenigo MN, Battistessa R, Faelli A.
    Journal: Boll Soc Ital Biol Sper; 1984 May 30; 60 Suppl 4():169-74. PubMed ID: 6147149.
    Abstract:
    In vitro experiments on everted sacs of jejunum and ileum of very young, adult and old rats have shown that intestinal transport activity (D-glucose, Na+ and water transports) decreases with age and that a contemporaneous electrolytes embalance of the enterocyte, occurs. Experiments with brush border membrane vesicles of enterocytes of different ages seem to suggest that the entry mechanism of solutes into the cell is, to same extent, involved.
