[Effect of pH on the motility of isolated jejunal loops in dogs].
Thirty-Vella jejunal loops are perfused at a constant rate with solutions of variable pH (1.55-11.25). Net loop absorption and motility of the oral segment do not significantly vary between pH values of 2.2 to 10.0. At a more acid pH, there exists a strong increase in the amplitude of pressure waves accompanied by a decrease in their frequence.
