The growth of DFA III-assimilating bacteria in the intestines of rats fed 3% DFA III for 2 weeks was examined. Sixty-four percent of the DFA III intake had been assimilated on day 3 of ingestion, and almost all of the DFA III was assimilated at the end of the experiment. The DFA III-assimilating bacterium, Ruminococcus productus, in DFA III-fed rats was in the stationary state of 10(8)-10(9) ce...
Bile acids were estimated in the duodenum of infants with protracted diarrhoea and compared with those in a control group. Significantly lower levels of total bile acids were found in infants with protracted diarrhoea, a finding which may be due to ileal dysfunction. Low concentrations of total bile acids may contribute to the poor nutritional state of these patients by impairing the normal dig...
The Na+ -taurocholate cotransporting polypeptide (NTCP/SLC10A1) is believed to be pivotal for hepatic uptake of conjugated bile acids. However, plasma bile acid levels are normal in a subset of NTCP knockout mice and in mice treated with myrcludex B, a specific NTCP inhibitor. Here, we elucidated which transport proteins mediate the hepatic uptake of conjugated bile acids and demonstrated intes...
Gallbladder bile of the bullfrog, R a m catesbezana was found to contain a number of minor bile acids and bile alcohols in unconjugated forms. The following bile acids and bile alcohols were identified by combined gas-liquid chromatography-mass spectrometry: cholic acid, allocholic acid, 3a,7a, 12a-trihydroxy-5a-cholestan-26-oic acid, 3a,7a, 12atrihydroxy-24-methyl-5~-cholestan-26-oic acid, 3a,...
The direct quantitative measurement of total bile acids in serum has been achieved using an enzymatic fluorescent method with a dual-beam spectrophotofluorimeter. By use of a 3alpha-hydroxysteroid dehydrogenase, oxidation of bile acids with NAD is completed in 200 seconds with the observed NADH fluorescence being proportional to the concentration of serum bile acids. This method is rapid (8 min...
Methods currently in use for the quantitative measurement of sulfated serum bile acids usually lead to low recoveries. The present technique uses two internal standards and involves enzymatic hydrolysis followed by extraction of the non-sulfated fraction in ether at pH 4.6. The sulfated fraction is then solvolysed before gas-liquid chromatographic analysis of the individual bile acids of both f...
The composition of bile acids in human bile was determined in bile-rich duodenal fluid on four consecutive days in a group of seven patients with cirrhosis and eight control patients with no liver disease. There was a marked reduction of secondary biliary bile acids in cirrhotic patients. Possible mechanisms for these changes are discussed.
