Radiation decreases murine small intestinal HCO3- secretion.
June 12th, 2011
While secretagogue-induced diarrhea is rich in chloride (Cl(-)) and bicarbonate (HCO(3) (-)) anions, little is known about diarrhea or its anionic composition following irradiation. We performed studies to characterize the differences between cyclic adenosine monophosphate (cAMP)-stimulated anion secretions in irradiated and non-irradiated mice.
MATERIALS AND METHODS:
HCO(3) (-) secretion was examined in basal, cAMP-stimulated, and irradiated jejunal tissues from BALB/c (Bagg albino) mice. The abdomens of the mice were γ-irradiated using a caesium-137 source.
