Changes in electrical potential difference and sodium-potassium ATPase of canine mucosa after jejunal-ileal bypass surgery.

Changes in electrical potential difference and sodium-potassium ATPase activity of rectal mucosa in dogs were examined before and after jejunal-ileal bypass surgery. The potential difference in the postoperative period was significantly higher (P less than 0.05) than the preoperative value. The potential difference increased by 160% at the 3rd day after the… (More)
