Basal biliary secretion in conscious chicken and role of enterohepatic circulation

Abstract

1. 1. Enterohepatic circulation of bile salt role. its interruption effects, gallbladder contribution and importance of some electrolytes, on total biliary secretion of chicken have been investigated. 2. 2. The gallbladder, in spite of its anatomical disposition, behaves exactly like that of mammals. When the vesicular duct is tied there is a retrograde now of bile from gallbladder, although it causes no change in the results if a cholecystokinetic stimulus is not introduced. 3. 3. The role of the enterohepatic circulation is important in this species. The results leave out electrolyte loss and indicate bile salt concentration decay as cause of hyposecretion after bile drainage, which agrees with lack of change of flow independent of bile salt. 4. 4. Recovery of all parameters when bile is placed in duodenum shows that the observed effects are genuine and that animals were in good physiological state.
