Insulin modulates rat intestinal glucose transport: effect of hypoinsulinemia and hyperinsulinemia.


The current studies were designed to evaluate the role of plasma insulin and glucose as regulators of intestinal glucose transport in vivo. Initially, rats received either intravenous glucose infusion or intraperitoneal streptozotocin to induce sustained hyperglycemic hyperinsulinemia or hyperglycemic hypoinsulinemia. Net jejunal uptake rates of glucose… (More)
