Sasanquasaponin, a bioactive compound isolated from seeds of Camellia oleifera, shows central effects in our previous research. In order to investigate its neuroprotective effects, a new kind of nanocapsule with photo responsiveness was designed to deliver sasanquasaponin into the brain and adjusted by red light. The nanocapsule was prepared using sasanquasaponin emulsified with soybean lecithi...

The partial phase behavior of systems composed of lecithin/isopropyl myristate (IPM)/water or ketorolac tromethamine (KT) solutions (2.5, 5, 10 and 50% w/w) at various lecithin/IPM weight ratios (km) have been investigated by the construction of phase diagrams. A commercially available soybean lecithin (namely, Epikuron 200, phosphatidylcholine purity greater than 95%) was used in this study. P...

The aim of this study was to determine the effect of low levels of glutathione on post-thawed buck sperm quality. In this experiment, different concentrations of glutathione [0 (LG-0), 0.5 (LG-0.5), 1 (LG-1), 1.5 (LG-1.5), and 2 (LG-2) mM] were added in a soybean lecithin-based extender. A total of 16 ejaculates from four bucks were collected and pooled. Each pooled sample was divided into five...

A beneficial effect of dietary phospholipid (PL) supplementation in purified diets in terms of survival, growth, resistance to stress tests, and occurrence of deformities has been demonstrated in larval and juvenile stages of various species of fish and crustaceans. The exact, determination of PL requirements in larvae is complicated due to the difficulty to bio-encapsulate PL in live prey. Fur...

Soybean lecithin transphosphatidylated phosphatidylserine (SB-tPS) was prepared from soybean lecithin and L-serine by a transphosphatidylation reaction, and its effect on age-related memory impairment was evaluated in rats by the Morris water maze test. Continuous oral administration of SB-tPS (60 mg x kg(-1) x d(-1) for 60 d) to male aged rats (24-25 mo) significantly improved performance in t...

A two phases process consisting of a soya lecithin (SL)-based soil washing process followed by the photocatalytic treatment of resulting effluents was developed and applied at the laboratory scale in the remediation of an actual-site soil historically contaminated by 0.65 g/kg of polychlorinated biphenyls (PCBs). Triton X-100 (TX) was employed in the same process as a control surfactant. SL and...

The first long-term double-blind placebo controlled trial of high dose lecithin in senile dementia of the Alzheimer type is reported. Fifty one subjects were given 20-25 g/day of purified soya lecithin (containing 90% phosphatidyl plus lysophosphatidyl choline) for six months and followed up for at least a further six months. Plasma choline levels were monitored throughout the treatment period....

Chocolates consist of a suspension of fine cocoa solids and sugar particles dispersed in a continuous lipid phase in a process assisted by emulsifiers, usually a combination of lecithin and PGPR. In the conventional process, the tempering is a pre-crystallization step in which the melted mass is cooled at a controlled rate of temperature decay under continuous shearing action in order to organi...

Background: Trehalose, a non-permeable disaccharide, has a protective role related both to osmotic effect and specific interactions with membrane phospholipids, rendering hypertonic media, causing cellular osmotic dehydration before freezing, and then decreasing the amount of cell injury by ice crystallization. Within this study, an attempt was made to evaluation of two levels of 50 and 100 mM ...

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...
