Ammonium effects on colonic Cl- secretion: anomalous mole fraction behavior
RT Worrell, J Oghene… - American Journal of …, 2004 - journals.physiology.org

Mechanism of cholinergic regulation of electrolyte transport in rat colon in vitro
TW Zimmerman, JW Dobbins… - American Journal of …, 1982 - journals.physiology.org

Cholinergic ion secretion in human colon requires coactivation by cAMP
M Mall, M Bleich, M Schurlein, J Kuhr… - American Journal …, 1998 - journals.physiology.org
Cl− secretion in the colon can be activated by an increase of either intracellular Ca2+ or
cAMP. In this study we examined a possible interdependence of the two second-messenger …

Segment-specific effects of epinephrine on ion transport in the colon of the rat
S Hörger, G Schultheiß… - American Journal of …, 1998 - journals.physiology.org
The effect of epinephrine on transport of K+, Na+, Cl−, and HCO 3− across the rat colon was
studied using the Ussing chamber technique. Epinephrine (5× 10− 6 mol/l) induced a …

[PDF][PDF] Disturbance of cholinergic regulation of electrogenic epithelial ion transport in the inflamed colon
T Yamamoto, Y Katuki, M Kadowaki - Digestive Disease Week, 2010 - academia.edu
The colon has mechanisms for both absorbing and secreting water and electrolytes through
the epithelial transport systems. These transport systems are considered to play important …

Basolateral Ca2+‐dependent K+‐channels play a key role in Cl—secretion induced by taurodeoxycholate from colon mucosa
The diarrhea associated with malabsorption of bile salts such as the secondary hydrophobic
taurodeoxycholate (TDC) may be partly explained by the TDC‐induced increase in colon …
