Familial lecithin-cholesterol acyltransferase deficiency.
Familial lecithin-cholesterol acyltransferase deficiency is an uncommon autosomal recessive disorder from a heritable defect in esterification of plasma cholesterol. In 1968, the disease was described by Gjone and Norum in Norway. Our case was a 38-year-old woman. Her disease was manifested by presence of lower extremities edema, proteinuria, corneal opacities, increased plasma cholesterol, and...
متن کاملLecithin Based Pseudoternary Phase Diagrams
Aim: Different promising colloidal delivery systems including microemulsions and liquid crystals could be obtained with suitable combination of oil, surfactants/cosurfactants and water. However, the main problem from a formulation point of view has been to choose the surfactants capable of forming such systems and be physiologically acceptable in the same time. To overcome the later shortcoming...
متن کاملFatty Acids of Liver Lecithin
The phospholipids, along with cholesterol, are now recognized as essential elements of tissues, while the characteristic constituents of the phospholipids are the fatty acids. In any study of the metabolic activity of tissues the nature and proportions of the various fatty acids in the phospholipids therefore become important and have been the subject of increasing interest and speculation. Bec...
متن کاملA simplified purification of lecithin.
A practical and easily reproducible method for preparing lecithin of a high degree of purity is urgently needed in connection with the use of lecithin in cardiolipin antigens (1, 2). Methods devised for this purpose have been published (3, 4), but the procedures, based on the classic studies of Levene and his coworkers (5, 6), were somewhat tedious and the lecithins so prepared have not always ...
متن کاملPassages in Lecithin-Water Systems
Large numbers of tunnel-like structures apparently connecting neighbouring bilayers were found in phase-contrast microscopy of certain preparations of egg lecithin in water. These passages either cause a pairing of the bilayers or form threedimensional lattices. They appear to originate while the lecithin swells in water. Some theoretical aspects of passage formation in fluid bilayers is shown ...
