[The use of a computer program to study gallbladder motor function].
Gallbladder motility was studied in 30 women by means of an ultrasonographic method. Gallbladder volume was examined during intravenous infusion of ceruletide (15 ng Takus/min in 0.9% NaCl solution). It was several dozen less than the dose given intramuscularly. The volume and ejection fraction were defined by the ellipsoid Dodds method in the computer programme Cardio 500. During the infusion of ceruletide it was possible to identify exactly the dose of the drug in every moment and to correlate it with the gallbladder volume. Contour's analysis in Simpson's method made possible to evaluate the contractility of individual parts of the gallbladder.
