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...

In normal serums of the majority of mammalian and avian blood there exists certain substances capable of activating venom haemolysin. They are extractable from serum by means of ether, and are capable of conferring upon the originally non-activating serum a power to activate venom, when mixed with the latter. The ethereal extract consists of fatty acids, neutral fats and possibly also some ethe...

The purpose of this study was to investigate the effect of dietary lecithin on skeletal muscle gene expression of collagen precursors and enzymes involved in collagen synthesis and degradation. Finisher gilts with an average start weight of 55.9 ± 2.22 kg were fed diets containing either 0, 4, 20 or 80 g/kg soybean lecithin prior to harvest for six weeks and the rectus abdominis muscle gene exp...

Ultracentrifugal analysis of the plasma of squirrel monkeys at various times after the injection of [Me-(14)C]choline revealed the specific activities of lecithin in both high (HDL) and low (LDL) density lipoproteins to be similar. This was also true for sphingomyelin. The exchange of phospholipids in vitro was studied by incubating unlabeled plasma with labeled LDL and HDL isolated 40 hr after...

We elucidate the effects of incorporating surfactants into electrospun poly (ɛ-caprolactone) (PCL) scaffolds on network homogeneity, cellular adherence and osteogenic differentiation. Lecithin was added with a range of concentrations to PCL solutions, which were electrospun to yield functionalized scaffolds. Addition of lecithin yielded a dose-dependent reduction in scaffold hydrophobicity, whi...

Lecithin-cholesterol acyltransferase (LCAT) is a plasma enzyme which catalyzes the transacylation of the sn-2-fatty acid of lecithin to cholesterol, forming lysolecithin and cholesteryl ester. We have recently proposed a covalent catalytic mechanism for LCAT in which lecithin cleavage proceeds via the formation of a transition state tetrahedral adduct between the oxygen atom of the catalytic se...
