1. Gall bladder contractility was present in 16 patients before the procedure.
2. It is currently thought that cholesterol gall stones arise because of a triple hepatobiliary defect: cholesterol supersaturation of gall bladder bile, reduction gall bladder contractility, and increased rate of cholesterol nucleation, probably due to mucin glycoprotein hypersecretion.
3. To measure oesophageal body motility, variables measured were: (1) amplitude of contraction (mm Hg), defined as the difference between the baseline pressure and the maximal pressure during the pressure event; (2) duration of contraction (s), defined as the time elapsed between the start and the end of the pressure event; (3) area under the pressure curve (mm Hgs), calculated from the sum of all pressure values between the start and the end of the pressure event, multiplied by the sampling interval; (4) propagation velocity (cm/s), defined as the speed of a contraction and calculated from the delay time and the distance between the sensors; (5) contractility (mm Hg/s), defined as the maximal increment between consecutive pressure values divided by the sampling interval; (6) total contractions (No/24 h), defined as pressure curves that are not rejected as artifacts; (7) propagated contractions (No/24 h), defined as contractions that are detected by a proximal pressure transducer and followed by a contraction at the distal sensor.
4. To avoid multiple testing, only the major variables of interest were analysed - that is, for acid reflux: total reflux time, number and duration of reflux episodes; for oesophageal motility: contraction amplitude and duration, area under the curve, propagation velocity, contractility, and number of contractions. p Values 0.05 were considered as significant.
5. Elevation of blood glucose, ketone bodies and free fatty acids in particular may be deleterious to the injured area of myocardium and predispose to arrhythmias (Oliver et al, 1968), impaired contractility or larger infarcts (Kjekshus and Mjs, 1972; Liedtke et al, 1978; Vik-Mo Mjs, 1981) compared to non-diabetics, predisposing to cardiogenic shock or left ventricular failure.
6. For example, progesterone impairs gall bladder contractility, and oestrogens may increase cholesterol saturation of bile and gall bladder prostaglandin synthesis, and thus possibly mucin secretion by the gall bladder mucosa.
7. Table III shows that cisapride further increased the orpoagation velocity of oesophageal contractions but had no significant effect on oesophageal contractility (slope of the contraction curve) or on the number of total, propagated, and non-propagatd contractions.
8. Gall bladder contractility was present in nine of the 10 patients at follow up; in two of these patients a non-contractile gall bladder had become contractile and in one patient, gall bladder contractility had been lost.
9. This would facilitate the calculation of peristaltic velocity and the speed of contractility of gut smooth muscle with high temporal resolution.
10. von Scheidt et al assessed haemodynamic variables over a 5 year period (mean 26 months) in patients after heart transplantation and confirmed preserved and normal left ventricular contractility in most cases.
11. Later, circular smooth muscle beneath the acutely inflammed mucosa of patients with ulcerative colitis was shown to have reduced contractility.
12. Alternatively, smoking could exert an effect on gall bladder contractility, possibly by inhibition of prostaglandin synthesis.
