Effects of acid and bile salts on the rabbit esophageal mucosa
Digestive Diseases and Sciences, 1981We used the rabbit esophagus as a model to study clinically significant variables which may be important in the pathophysiology of reflux esophagitis in man.* Increased permeability to hydrogen ion, as indicated by a net acid flux (NAF) out of the lumen, was our index of injury.

Effects of oleic acid and bile salts on canine villous motility
Life Sciences, 1989The effects on canine villous motility of mucosal Tyrodes solution containing oleic acid (10 mM) and/or either taurocholic or cholic acid (15 mM) in the presence or absence of IV atropine (1 mg/kg) was used to assess the neural mediation of the effects of luminal nutrients. Villous motility was measured over 12 min periods by in vivo videomicroscopy of

Effect of bile salts and bile acids on human gastric mucosal epithelial cells
Journal of Nanjing Medical University, 2008Abstract Objective To explore the effect of bile salt and bile acid on cultured eternalized human gastric mucosa epithelium GES-1cells. Methods Cultured eternalized human gastric mucosa epithelium GES-1 cells were treated with media containing 6 different kinds of bile salts and 3 different kinds of bile acids and their mixture with different ...

Group separation of bile acids and salts by silicic acid column chromatography
Analytical Biochemistry, 1978Abstract Group separations of unconjugated and conjugated bile acids and salts were performed using mixtures of conventional solvents by chromatography on columns of silicic acid. The results suggest that this method is useful for group separations of mono-, di-, and trihydroxycholan-24-oic acids and their conjugates with good recoveries. This method

Bile and pancreatic secretion in chickens: the effects of bile salts, feeding and acid
Comparative Biochemistry and Physiology Part A: Physiology, 1978Abstract 1. 1. Bile production decreased after bile diversion, but increased when bile was returned to the duodenum, and during i.v. infusion of chenodeoxycholic and of taurocholic acid. In chickens, unlike rabbits, rats and guinea pigs, only a small fraction of bile flow was apparently independent of bile salt secretion. 2. 2.

Bile acid and bile salt disrupt gastric mucosal barrier in the dog by different mechanisms
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1982The present study was undertaken to assess the mechanism by which protonated taurocholic acid disrupts the gastric mucosal barrier. By the criterion of lecithin solubilization, the critical micellar concentration of taurocholic acid (pH 1) was 4.5 mM, as opposed to 3.0 mM for sodium taurocholate (pH 7).

Bilirubin, the yellow-orange tetrapyrrole pigment of jaundice, is essentially insoluble in pure water, but is much more soluble in solutions of bile salts such as sodium taurocholate. The biophysical chemistry of bilirubin in bile salt solutions is affected by changes in the pH of the solution in the range 5-9, suggesting that interactions with bile ...

Adsorption of bile acid by chitosan salts prepared with cinnamic acid and analogue compounds
Journal of Biomaterials Science, Polymer Edition, 2006A chitosan (CS) powder treated with cinnamic acid and an analogue compound (CN) was prepared as CS-CN. Using it, bile acid adsorption by CS-CN and the release of CN were investigated in vitro. When CS-CN was soaked in a taurocholate solution, it released CN and simultaneously adsorbed the bile acid.

Summary:Breast milk jaundice has been reported to be associated with increased lipase activity and elevated free fatty acid (FFA) concentrations within breast milk. We have previously shown that bile salts are present in small concentrations in breast milk and the aim of this study was to examine the relationship of bile salt‐stimulated lipase (BSSL ...

Activities and viscosities of aqueous bile acid salt-lecithin solutions
Journal of Solution Chemistry, 1972Isopiestic and viscosity measurements on aqueous sodium cholate-lecithin solutions are reported at high concentrations which include the physiological region as a lower limit. At low cholate concentration, the addition of lecithin increases the activity of water, consistent with earlier studies showing increases of micellar weights.
