The role of cholestanol in the pathogenesis of cholesterol gallstones . Review : Hypothesis and Conception ( 1991 ) Jacob

چکیده

The results allow proposing a novel hypothesis and concept of cholesterol gallstone pathogenesis in man: cholestanol may be responsible for the cholesterol supersaturation of gallbladder bile, aseptic inflammation of the gallbladder mucus and consecutive hypersecretion of glycoprotein mucin, gallbladder hypomotility as well as for the heterogenic nucleation process and precipitation of cholesterol monohydrate crystals. Collectively, those data may suggest that cholestanol is likely to play an important role in cholesterol gallstone formation and the cholestanol/cholesterol ratio may be an initializing factor in this process. An increased ratio of cholestanol to cholesterol in bile may be a marker of cholesterol gallstone disease before cholesterol gallstone formation.

Relation of cholesterol metabolism to pediatric gallstone disease: a retrospective controlled study

BACKGROUND Cholesterol metabolism may be involved in pediatric gallstone disease. We aimed to reveal cholesterol metabolites and phytosterols and their relation to stone composition of sterols in children having black pigment and cholesterol stones. METHODS We performed retrospective controlled clinical study, in which we examined parameters of cholesterol metabolism and liver function values...

The concentration of heavy trace elements in pigment and cholesterol humangallstones: Comparative studies by PIXE analysis.

Background: The method of proton induced X-ray emission (PIXE) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. The sensitivity of this powerful method is in the order of ppm .The aim of this work is to analyze structural composition of 4 heavy trace elements with Z greater than 24 (Mn, Fe, Cu, Zn) in two kinds of gallstones and to...

High levels of plant sterols and cholesterol precursors in cerebrotendinous xanthomatosis.

We measured the cholestanol, cholesterol precursor (lathosterol), and plant sterol (campesterol and sitosterol) concentrations of serum and bile in 11 patients with cerebrotendinous xanthomatosis. The mean values of serum cholestanol, lathosterol, campesterol, and sitosterol were, respectively, 8.4-, 2.5-, 2.7-, and 1.4-times higher in the patients than in normal control subjects (n = 26). Chol...

Gallstone disease.

Gallstone disease is one of the most prevalent gastrointestinal diseases with a substantial burden to health care systems that is supposed to increase in ageing populations at risk. Aetiology and pathogenesis of cholesterol gallstones still are not well defined, and strategies for prevention and efficient nonsurgical therapies are missing. This review summarizes current concepts on the pathogen...

Experimental cholelithiasis in the rabbit induced by cholestanol feeding: effect of neomycin treatment on bile composition and gallstone formation.

Fed cholestanol is converted by the rabbit to 5alpha-bile acids which coprecipitate with the normally occurring 5beta-bile acids to form gallstones composed of calcium and sodium glycoallodeoxycholate and glycodeoxycholate. The present study shows that oral administration of large doses of neomycin prevents gallstone formation in the cholestanol-fed rabbit and reduces the elevated concentration...
