Radiation decreases murine small intestinal HCO ₃ ⁻ secretion

Abstract

Anion secretions in irradiated mice, being primarily Cl(-) and minimally HCO(3)(-), differ from that of secretagogue-induced anion secretions. Understanding anion loss will help us correct electrolyte imbalances, while reduced HCO(3)(-) secretion in the upper-gastrointestinal tract might also have implications for irradiation-induced nausea and vomiting.
