Effects of cholesterol gallstone induction on gallbladder function and bile salt pool size in the prairie dog model. 1978

P D Meyer, and L Den Besten, and N J Gurll

The prairie dog gallstone model was used to test the following hypotheses: (1) gallbladder stasis occurs in association with gallstone formation, and (2) bile salt pool size decreases as gallstones develop. Bile salt pool sizes and the extent of equilibration of hepatic and gallbladder bile salt over the course of gallstone development were measured. No evidence for bile salt pool reduction was found, but there was significant evidence of progressively inefficient equilibration of hepatic and gallbladder bile salt very early during gallstone formation. These changes, suggestive of gallbladder stasis and observed only in the presence of cholesterol crystals in bile, persisted as cholesterol stones developed and antedated any reduction in bile salt pool size.

D005704	Gallbladder	A storage reservoir for BILE secretion. Gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the CYSTIC DUCT to the DUODENUM, for degradation of dietary lipid.	Gallbladders
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001647	Bile Acids and Salts	Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones.	Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
