The kinetic mechanism of gallstone formation / 中国普通外科杂志

ABSTRACT

Objective To probe into the kinetics of gallstone formation.Methods Fifty seven rabbits were divided into five groups (1) normal control with standard fodder, (2)1 2% cholesterol was added into the fodder,(3)1 2% cholesterol plus indomethacin in the fodder,(4)1 2% cholesterol plus erythromycin,(5) 1 2% cholesterol plus Dong Li San, a Chinese herb compound. All animals were feed four weeks before measurement.Results Gallstone developed in 0 out of 13 in group 1, in 12 out of 14 rabbits in group 2, in 4 out of 10 rabbits in group 3, in 0 out of 10 in group 4, and in 2 out of 10 in group 5. Compared with that in group 1 rabbits in group 2 had higher level of cholesterol and mucin in bile,much higher common bile duct pressure and cystic duct resistance,much lower gallbladder emptying rate ( P
