21.   This causes a build up of pressure in the solution compartment until, at equilibrium, the pressure exactly counteracts the tendency for further solvent flow.

22.   Measurements of hepatic venous pressure gradient with the balloon occlusion technique, however, estimate the sinusoidal perfusion pressure in a relatively large area of the liver.

23.   Previous study of colonic pressures in paediatric patients has been limited mainly to the rectosigmoid area, because of relative inaccessibility of the proximal colon.

24.   There is minimal information about patterns of USO pressure in children with problems believed to be related to oesophagopharyngeal reflux.

25.   Nadir pressure was referenced to the prevailing midoesophageal body pressure in that second and so took into account changes of basal oesophagela body pressure produced by common cavity episodes.

26.   When the level of arousal was taken into account there was no significant difference of UOS pressure in this group compared with any of the other three symptom groups.

27.   Our study has monitored UOS pressure in unsedated children and established the occurrence of transient UOS relaxations in children, which may contribute to oesophagopharyngeal reflux.

28.   Bethanechol produced a dose dependent increase in intraluminal gall bladder pressure in animals treated with saline.

29.   Resting anal pressure in older patients did not differ significantly from that in younger patients either before or after the operation.

30.   Resting and pressure in older patients did not differ significantly from that in younger patients, either before or after operation.
