The effect of colonic distension and changes in intraluminal pH and osmolality have been investigated in patients with well established colostomies. Small volumes of acidic buffer (pH4) and hypertonic saline (4%) were found to be only a very weak peristaltic stimulus. Strong hypertonic solutions (glycerine BP) induced a poorly sustained peristaltic response in the majority of cases. Distension ...
Peristaltic pumping induced by a sinusoidal traveling wave in the walls of a two-dimensional channel filled with a viscous incompressible fluid mixed with rigid spherical particles is investigated theoretically taking the slip effect on the wall into account. A perturbation solution is obtained which satisfies the momentum equations for the case in which amplitude ratio (wave amplitude/channel ...
