1.   As expected there was direct correlation between total net solute absorption and net water absorption both in normal and secreting intestine.

2.   Net absorption of sodium decreased in patients with acute diarrhoea in the absence of liminal SCFA, but returned to normal with luminal SCFA.

3.   Net absorption of water and electrolytes was calculated using standard formulas.

4.   Table II shows that control subjects had net absorption of water and sodium with solutions I and II.

5.   A large net fluid absorption was then recorded.

6.   Radioactive tracer studies suggested that the increase in the SCC reflected a change in sodium and chloride transport from net absorption to net secretion.

7.   Net absorption is the difference between the amount of space leased and the amount given up through departures.
