Objective:Using biological technique to probe into the mechanisms of regulating the biliary kinetics of Yang-Gan-Rou-Gan therapy(YGRG)of TCM in the prevention and treatment of pigment gallstone disease Methods:60 guinea pigs were divided randomly into three groups:group A (fed normal diet,n=20),group B(fed lithogenic diet,n=20)and group C (fed lithogenic diet with YGRG drug).

Effect of truncal vagotomy on biliary dynamics in dogs;

Objective To study the relationship of the gallbladder shrinking function and post-cholecystectomy blocked dynamia(PCBD) in patients with cholelithiasis and cholecystitis.

At the end of the feeding period, the gallbladder motility was assessed and then four bipolar silver electrodes were implanted on the antrum, duodenum, jejunum, and ileum.
