Alteration of aquaporin mRNA expression after small bowel resection in the rat residual ileum and colon.

 · 1970

BACKGROUND: Diarrhea occurring after small bowel resection gradually improves due to intestinal adaptation. It is known that several water channels, termed aquaporins (AQP), are expressed in the gastr…
