We determined the distribution of lecithin molecular species between vesicles and mixed micelles in cholesterol super-saturated model biles (molar taurocholate-lecithin-cholesterol ratio 67:23:10, 3 g/dl, 0.15 M NaCl, pH approximately 6-7) that contained equimolar synthetic lecithin mixtures or egg yolk or soybean lecithins. After apparent equilibration (48 h), biles were fractionated by Supero...

Cholesterol and dietary phospholipids are important to the growth and survival of crustaceans. Soy lecithin enhances cholesterol solubilization while phosphatidylcholine transfers cholesterol from the hepatopancreas to the hemolymph. To study the influence of dietary lecithin on digestibility and transport of cholesterol to the hemolymph in Artemesia longinaris, diets with different levels of s...

IT has been reported in a previous communication [Spiegel-Adolf, 1932, 1] that, contrary to the Hofmeister series, colloidal solutions of egg-lecithin show a greater decrease in viscosityon addition of bromides than on addition of chlorides, iodides and thiocyanates. These results combined with more recent interferometric studies [Spiegel-Adolf, 1932, 2] were explained as due to reaction of mol...

The main objective of this work was to increase the retarding effect of the acid dye Telon(®) Blue RR (C.I. Acid Blue 62; DyStar, Frankfurt, Germany) release on polyamide fibres dyeing by encapsulation of the dye in liposomes as an alternative to synthetic auxiliaries, in order to reduce effluent pollution. The retarding effect achieved with the use of mixed cationic liposomes of dioctadecyldim...

CHOLESTEROL IS THE MAIN COMPONENT of human gallstones. It is held in solution in bile by mixed micelles of lecithin and bile salts [l]. Presence of both lecithin and bile salts are ersential for the solubilization of cholesterol in bile [2]. Normal human gallbladder bile is almost saturated with cholesterol [3]. Therefore, a small change in lecithin concentration might disturb the micellar solu...

Infertility is well-established harmful effect in chronic alcoholism and so far, there is no effective treatment for this condition. The study was conducted to determine the effects of lecithin, a known hepatoprotective on ethanol induced testicular injuries in male albino rats of Wistar strain. Five groups (n=6) of animals were used. Group I served as control. Group II received daily 1.6 g eth...

It has been known that the addition of bile salts to lecithin organosols induces the formation of reverse wormlike micelles and that the worms are similar to long polymer chains that entangle each other to form viscoelastic solutions. In this study, we further investigated the effects of different bile salts and bile acids on the growth of lecithin reverse worms in cyclohexane and n-decane. We ...

fhere have been many works on lecithin contained in the brain of human and mammal living on land as well as on lecithin in the egg of hen. The works on lecithin in the brain of human and mammal were reported by Yokoyama & Suzuki (1932 ab) md Levene & Rolf (1921, 1922). Reviewing the works on lecithin in the brain )f sea mammal, Igarashi & Zama (1955) studied on lecithin in the brain of sperm wh...

. Egg and soy lecithins are commonly used in the food industry as emulsi®ers (E322). The possibility of residual proteins leads to suspicion of their role in allergic manifestations in subjects allergic to egg or soy. Two cases are reported in which the double-blind, placebo-controlled oral challenge (DBPCOC), the ``gold standard'' of diagnosis, led to con®rmation that lecithin had caused lesio...
