in this study, the effects of dietary egg lecithin on digestive enzymes and body biochemical composition of juveniles mesopotamichthys sharpeyi was evaluated. four experimental diets including control diet (with 0% egg lecithin) and three diets containing 2%, 4% and 6% egg lecithin were used. at the end of the experiment, digestive enzymes activity (lipase, amylase and alkaline phosphatase) and...

The activity of egg lecithin in preventing the antifungal action of the two imidazole antimycotics, clotrimazole and miconazole, was confirmed. However, addition of this phospholipid could not relieve an existing imidazole inhibition. Compared with egg lecithin, reduced egg lecithin showed no such protective effect. The addition of egg lecithin to an aqueous suspension of the imidazole drugs ch...

the effect of various amount of soybean lecithin replaced with egg yolk to protect the ram semen in times of one hour after semen collection, as well as 24 and 48 hours after the semen store at 5°c was evaluated. semen was collected weekly for 8 weeks from 10 rams with 2-3 years old and average body weights of 64 kg. semen samples were pooled and divided into 4 parts. each part was diluted with...

Proton nuclear magnetic resonance (PMR) spectra at 270 MHz of aqueous dispersions of nonsonicated egg lecithin, dipalmitoyl lecithin, egg lecithin-cholesterol (1 : 1 ) and dipalmitoyl lecithin-cholesterol (1 : 1), together with PMR spectra of mitochondrial membranes and their extracted lipids, have been obtained. Carbon-13 nuclear magnetic resonance (CMR) spectra at 25.2 MHz of egg lecithin, eg...

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 ...

. 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...

Surface potentials of mixed monolayers of dicetyl phosphate and eicosanyl trimethylammonium bromide (1:1) were the same on subsolutions of 0.02 M NaCl or 0.01 M CaCl(2), which indicated that ionic phosphate does not interact with Ca(++) in the presence of a neighboring trimethylammonium group. Surface potential-pH plots of dicetyl phosphate, and of dipalmitoyl, egg, and dioleoyl lecithins showe...

this study was conducted to evaluate the effect of different lecithin sources and their levels on growth performance and resistance to anoxia stress of rainbow trout (oncorhynchus mykiss) alevin with initial weight of 120 ± 4.08 g for 40 days. soybean and egg lecithin at 2, 4 and 6 ? levels were added to the diets. seven treatments by three replications were used in this experiment. therefore, ...

Egg yolk low-density lipoproteins (LDL) and soybean lecithin were evaluated as replacements for egg yolk in extenders used for the cryopreservation of brown-bear spermatozoa. The motility, viability and acrosomal status of post-thawed spermatozoa were analysed, and an egg-yolk extender was used as a control. The total antioxidant capacity of these extenders was tested. Soybean lecithin showed a...
