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
ABSTRACT
Bile collected from 28 cases with various hepatic or biliary diseases during operation was assayed for the ?-glucuronidase level. In Group I consisting of 14 patients with primary intrahepatic stone, the ?-glucuronidase level averaged 2250.67 u/dl, while in Group II consisting of 14 patieats with other hepatic diseases, it averaged only 463.99 u/dl(P = 0.01).The patients of both groups showed a declination of the enzyme level gostoperatively, but in Group I, the enzyme level raised with other hepatic diseases, he T-tube. The AMPS and MP contents of the bile .remarkable inhibitory effect on two substances exert their function in positive remarkable inhibitory effect on at pH4,6. It is believed that. ?-glucuronidase, Group 11 consisting the results of thisles in the reformation of biliary stones reformation biliaryWhen ?-glucuronidase level is lower than 200u/dl.Chinese traditional prescriptions with glycynrhizae liquid extract shows a remarkable inhibitory effect on this enzyme. In Chinese traditonal prescriptions, the drugs which can promote circulation and clear deposit are usually added. According to the results of this study, the authors suggest that the therapeutic effect of glycyrrhizae be emphasized.
