Effect of the addition of l-arginine (20 mmol/l) and l-NAME (20 mmol/l) to the perfusion solution on cholera toxin (CT) induced small intestinal water and electrolyte secretion
| CT | CT+ PES +l-arginine | CT+ PES + l-NAME | |
| Number | 16 | 8 | 8 |
| Net Cl− movement | −11.6 (−15.3 to −10.3) | −9.2 (−13.8 to −7.5) | −8.5 (−13.0 to −7.5) |
| Net Na+ movement | −17.1 (−18.1 to −13.5) | −17.0 (−18.1 to −13.5) | −15.9 (−16.4 to −12.7) |
Data are expressed as median (interquartile ranges) in μmol/min/g dry weight.
CT + PES + l-arginine, NS versus CT; CT + PES +l-NAME, NS versus CT.
