Transmural potential difference (PD), short-circuit current (Isc), and electrical resistance (R) were measured in the isolated mucosa of duodenum, jejunum, ileum, proximal cecum, rectum order to characterize properties chicken small large intestine. The intestine was classified into three categories, regarding its characteristics: 1) with four five times higher R than other segments lowest PD; 2) group formed by high PD low R; 3) rectum, R. In all segments, addition D-glucose luminal side stimulates Isc, this effect can be reversed phloridzin, indicating that glucose-induced Isc increase is due Na+-D-glucose co-transport. glucose maximal a fivefold increase, suggesting segment may have an important role absorption Na+ as well nutrients co-transported Na+.
