In this study, the effects of dietary chicken egg lecithin on some blood biochemical factors of Mesopotamichthys sharpeyi juveniles and resistance to thermal shock was investigated. Juveniles with initial average weight of 3.10±0.17 were stocked in 12 fiberglass tanks. Four isolipidic and isonitrogenic diets containing 0% (control), 2%, 4% and 6% chicken egg lecithin were used to feed the fish ...

BACKGROUND Previous studies have shown that plasma and urinary free choline concentrations decrease significantly during a marathon, and that these decreases may be associated with decreased performance. OBJECTIVE In a pilot study, we sought to determine whether lecithin supplementation prior to a marathon would maintain plasma free and urinary choline concentrations and improve performance v...

1. The soluble phospholipase D of cabbage was purified by heat treatment, acetone precipitation and electrophoresis on a density gradient of aqueous glycerol. 2. The purified enzyme slowly attacked a lecithin suspension whereas ultrasonically treated lecithin was hydrolysed more rapidly. 3. Diethyl ether stimulated the hydrolysis of both the lecithin suspension and ultrasonically treated lecith...

Introduction: Astaxanthin, a highly active oxidant, possesses potential effect on human health. However, with the oily characteristic, ability to disperse in an aqueous environment has limited its application. Therefore, aim of this study is fabrication stable astaxanthin emulsion water. Methods: In study, was fabricated using polysorbate (tween 60/80) or lecithin. The dispersing methods magnet...

A rapid and accurate single step procedure is described for the assay of lecithin-cholesterol acyltransferase activity. After incubation, using radiolabeled cholesterol as the substrate, an ethanolic solution of digitonin is added directly to the incubation mixture to extract the lipids. Excess cholesterol is then added, and the labeled cholesterol-digitonide along with denatured proteins are s...

1. The hypodermic administration of tethelin increases markedly the rate of growth of the primary tumor and the tendency to form metastases in rats inoculated with carcinoma, in this, as in other respects, reproducing the action of the whole anterior lobe of the pituitary body. 2. Other alcohol-soluble extractives of the anterior lobe of the pituitary body, with the exception of the lecithin fr...

Four patients with Friedreich's ataxia took part in an open trial, in which they consumed 50-100g/day lecithin granules (containing approximately 22% phosphatidycholine) for 16 weeks, but no improvement resulted. Several unwanted effects including diarrhoea, nausea, depression, "hot flushes" and weakness were experienced. Resting levels of free-choline in plasma were within the range found in 1...

Serum lipoamide dehydrogenase activity and kinetics were studied in nine patients with Friedreich's ataxia before and three months after therapy with oral lecithin. Results disclosed a significant reduction in LAD inhibition by NADH in all patients after therapy. Three patients normalized their increased Km for lipoamide and one patient showed the opposite results after therapy. Two patients ce...

Lipid-containing artificial tears are a type of artificial tears that use lipid components in order to restore the lipid layer of the tear film. One of these components is lecithin which can be applied in spray solutions containing lecithin liposomes. In this work the behavior of three of these commercial tears based on lecithin, Innoxa, Opticalm and Optrex, are studied using the Langmuir techn...
