Sulfated glycoproteins in normal human bile.
NAGASHIMA, H., SUZUKI, N. and YOSIZAWA, Z. Sulfated Glycoproteins in Normal Human Bile. Tohoku J. exp. Med., 1974, 113 (3), 225-229 Normal human bile was collected under aseptic condition. Subsequently, it was frozen without preservative until use. A mixture of 40 bile samples was fractionated centrifugally in the presence of salts. The resulting fractions showed strong coagulating effects on c...
متن کاملLack of effect of experimental ascorbic acid deficiency on bile acid metabolism, sterol balance, and biliary lipid composition in man.
Extensive studies in animal models indicate that subclinical ascorbic acid deficiency impairs the conversion of cholesterol to bile acid, elevates plasma cholesterol levels, and predisposes to development of cholesterol cholelithiasis. The present study was designed to see if this is also true in man. Five normal volunteers were hospitalized in a metabolic ward and placed on a controlled diet c...
متن کاملLipid composition of lipoproteins of normal human plasma.
It is now established that human blood plasma contains at least three distinct groups of lipoproteins. Although there are several physical methods of isolating lipoproteins, ultracentrifugation has proved to be the most precise. By this means, lipoprotein groups of known mean hydrated density have been isolated and characterized. These differ from each other in peptide composition (1, 2), lipid...
متن کاملSterol balance in the Smith-Lemli-Opitz syndrome. Reduction in whole body cholesterol synthesis and normal bile acid production.
The Smith-Lemli-Opitz syndrome (SLOS) is a multiple malformation/mental retardation syndrome caused by a deficiency of the enzyme 7-dehydrocholesterol Delta(7)-reductase. This enzyme converts 7-dehydrocholesterol (7-DHC) to cholesterol in the last step in cholesterol biosynthesis. The pathology of this condition may result from two different factors: the deficiency of cholesterol itself and/or ...
متن کاملEffects of fenofibrate on bile lipid composition.
In humans, clofibrate increases the degree of bile cholesterol saturation and predisposes patients to cholesterol gallstone formation. To determine if this activity extends to the related hypolipidemic agent fenofibrate, duodenal bile lipid composition was studied in 15 subjects before they participated in a double-blind study of that drug. Eight subjects were studied again on fenofibrate and s...
