Fluorometric measurement of fecal bile acids.
A method is described for the fluorometric determination of fecal bile acids. The method combines solvent extraction and thin-layer chromatography (TLC) isolation tech nics with a fluorometric method for measuring total bile acids. Recoveries of individual bile acids added to feces averaged 107% with a standard deviation of ± 5.6%. Bile acid excretion in normal human subjects on a self-selected...
متن کاملFecal Bile Acids of Xenarthra Species
The analysis of feces is a fundamental tool for field work, especially to identify the presence of certain species in an area. Fecal bile acids and their relative concentration follow patterns that are species-specific, and can be characterized by Thin Layer Chromatography (TLC). This technique has been used for differentiating feces of several mammal species; however it has never been used for...
متن کاملIsolated Fecal Microorganisms Capable of 7 Α-dehydroxylating Bile Acids
Strains of microorganisms capable of 7alpha-dehydroxylation of chenodeoxycholate were isolated from rat and human feces. All the strains were strictly anaerobic, non-motile, moderately themioresistant Gram-positive rods. They showed some saccharolytic properties with the production of both acid and gas. They were H(2)S-positive but indole-, skatole-, citrate-, catalase-, and oxidase-negative. T...
متن کاملBile Acids: An Underrecognized and Underappreciated Cause of Chronic Diarrhea
Bile acid malabsorption is a common cause of chronic watery diarrhea; however, its role appears to be poorly appreciated among clinicians. As such, bile acid diarrhea remains an underrecognized cause of chronic diarrhea, resulting in many patients incorrectly diagnosed and interfering and delaying proper treatment. In this review, we briefly discuss the synthesis, enterohepatic circulation, and...
متن کاملFecal Bile Excretion
Epidemiological studies have shown a positive association between cholesterol gallstones and colonic cancer. These two diseases may be somehow related with bile acids metabolic alterations. The aim of this study was to evaluate the profiles of fecal bile acid in gallstone patients, in order to estimate the quality and amount of fecal bile acids. A fecal bile acid profile of ten gallstone patien...
