the goal of this study was the evaluation of semen extender filtration on post-thawed buck sperm quality. a total 16 ejaculates were collected from four buck (4 ejaculates from each buck) twice a week. after semen collection and primary evaluation, collected semen samples were pooled and divided into two equal parts. each part was diluted with one of the following extenders: 1) non-filtered lec...

Egg lecithin is a complex mixture of phosphatides that consists mainly of phosphatidylcholine and phosphatidylethanolamine, combined with various amounts of other substances such as triglycerides and fatty acids [1]. As pharmaceutical excipient lecithin is used in parenteral emulsions, liposomes and mixed micellar solutions. It has been proved, that aqueous dispersions of lecithin (Water-Lecith...

Probiotic formulations containing lecithin phospholipids have been shown to extend their viability. However, the protective effect of and properties mixtures probiotic cells in aqueous media not fully documented. The aim this study was investigate interactions between Bifidobacterium animalis ssp. lactis (Bifido) probiotics lecithin. lecithin-Bifido were dependent on concentration. FTIR Raman s...

Incorporation of dietary phospholipids into lymph chylomicrons was studied in rats fed corn oil containing either radioactive lecithin or lysolecithin. The specific activity of lecithin-s2P in chylomicrons relative to that in the oil increased directly with the amount of lecithin fed, whereas the lecithin content of chylomicrons was constant. About 40% of the phospholipid in chylomicrons was de...

Lecithin, a naturally small molecular surfactant, which is widely used in the food industry, can delay aging, enhance memory, prevent and treat diabetes. The interaction between zein and soy lecithin with different mass ratios (20:1, 10:1, 5:1, 3:1, 2:1, 1:1 and 1:2) in ethanol-water solution and characterisation of zein and lecithin composite colloidal nanoparticles prepared by antisolvent co-...

The purpose of this review is to give an insight into the considerable potential of lecithin based nanocarriers. The lecithin microemulsion and closely related microemulsion based systems are currently of interest to pharmaceutical researchers. Conventional systems for topical delivery of drugs meet many hindrances like reduced permeation and entrapment efficiency. Lecithin nanocarriers with th...

Amniotic fluid phospholipids from 346 patients' specimens were quantified and evaluated against the clinical outcome (i.e., respiratory distress syndrome or normal respiratory function). Concentrations of lecithin, sphingomyelin, phosphatidylglycerol, and the lecithin/sphingomyelin reflectance ratio were evaluated by ordered frequency distribution and stepwise discriminant function analysis. Th...

Injection of choline-(3)H into choline-deficient rats resulted in an enhanced incorporation of the label into liver lecithin, as compared to the incorporation of label into liver lecithin of normal rats. The results obtained with the use of different lecithin precursors indicate that in the intact liver cell, both in vivo and in vitro, exchange of choline with phosphatidyl-choline is not signif...

We describe a new method of complete analysis for lecithin, lysolecithin, and sphingomyelin in amniotic fluid. The analysis is based on alkaline hydrolysis of the lecithins and the enzymic hydrolysis of sphingomyelin. The choline formed in each instance is enzymically phosphorylated with [gamma-32P]ATP to yield [gamma-32P]phosphorylcholine, which is isolated by anion-exchange chromatography and...

The present study was performed to determine whether the degree of lecithin hydrophobicity regulates bile metastability and, therefore, affects the process of cholesterol crystallization. Supersaturated model bile (MB) solutions were prepared with an identical composition on a molar basis (taurocholate/lecithin/cholesterol, 73:19.5:7.5; total lipid concentration 9 g/dl) except for the lecithin ...
