title: Effect of a maltodextrin-electrolyte, a maltodextrin-nutrient-electrolyte and a standard electrolyte solution on water and electrolyte fluxes in the secreting rat intestine.
abstract: The effects of a maltodextrin (dextrose equivalent 12)-electrolyte solution and a maltodextrin-electrolyte solution with added nutrients on net water and electrolyte transport in the secreting rat intestine was compared with the citrate-World Health Organization oral rehydration solution to determine the need for a clinical trial to evaluate the efficacy of these maltodextrin solutions in acute diarrhoea treatment. Cholera toxin consistently produced net water secretion (-36.5 +/- 9.9 mean +/- SEM microliter/min/g dry weight of intestine). All three solutions reversed the cholera toxin-induced net intestinal water secretion to net absorption. Significantly greater net water absorption occurred from the maltodextrin-electrolyte solution compared to the World Health Organization solution (P < 0.05) but not when compared to the maltodextrin-electrolyte-nutrient solution. Net sodium, potassium and chloride fluxes due to the World Health Organization-solution were not significantly different from the maltodextrin-electrolyte solution. These data provide a rationale for initiating a clinical trial.
