Boughton, K., Gandy, G., and Gairdner, D. (1970). Archives of Disease in Childhood, 45, 311. Hyaline membrane disease. H: Lung lecithin. The lecithin content of lung, together with its surface tension properties, were determined in 34 stillbirths, and 61 neonatal deaths. Lecithin content ranged widely from 1-5 to 18 6% of dry lung tissue. In 24 cases the 'palmitic-lecithin' was also measured; i...

We have shown previously that ox and pig bile accelerate in vitro growth of Giardia lamblia. We have now investigated the possible mechanisms by which mammalian biles promote parasite growth. Growth effects of (a) ox, pig, guinea pig, and human biles, (b) pure bile salts, and (c) egg and soybean lecithins were studied in the presence of a lecithin-containing growth medium. Individually, dilute ...

Four barrows of approximately 40 kg initial body weight, fitted with post-valvular T-cecum cannulas, were used to study the effect of lecithin as an external emulsifier on apparent ileal and overall digestibility of crude fat, fatty acids, and other dietary nutrients (DM, N, GE, crude fiber [CF], P, Ca, and Mg), as well as the utilization of N, GE, Ca, P, and Mg. Two levels of lecithin (0 and ....

Experiments on the transport of cholesterol, desmosterol and hydroxycholesterol from aqueous sodium taurocholate-lecithin and aqueous sodium cholatelecithin micelle systems into hexadecane have been carried out as a function of lecithin to bile salt concentration ratios. These data strongly support the previously proposed hypothesis that the kinetics of transport of cholesterol, desmosterol and...

Thioglycollate Broth Medium was used for culturing the test bacteria. Thioglycollate Broth Medium containing 0.5% sodium thiosulfate, O.S^o Tween ® 80, and 0.07% lecithin was used as the transplant medium. The sodium thiosulfate inactivates free iodine which mav be carried over. The Tween ® 80 and lecithin serve as inactivators for the quaternary compounds and hexachlorophene, and thioglycollat...

The aim of this study was to establish a freeze-drying process for melatonin-loaded lecithin/chitosan nanoparticles (NPs) to preserve their chemical and physical stability for a longer time period that what is possible in an aqueous suspension. Glucose and trehalose were investigated as potential excipients during freeze-drying of NP suspensions. Lecithin/chitosan NPs were characterised by mean...

Enzymes, capable of hydrolysing lecithin to liberate inorganic phosphate, are present in the kidney and intestinal mucosa (King, 1931). Since several pathways may lead from lecithin to inorganic phosphate and more than a single bnzyme must have been involved, it is uncertain which enzyme was the rate-limiting one in this investigation. In a recent paper Schmidt, Bessman & Thannhauser (1957) des...

Topical iodine forms are used for infected and necrotic pressure ulcers. Despite antimicrobial advantages several potential disadvantages were observed with controversial results. To clarify the controversy, the reactivity of povidone-iodine (PI) sugar ointment and cadexomer-iodine (CI) ointment toward biological components was investigated. L-Tyrosine as a component of proteins and egg lecithi...

In the absence of sterol, amphotericin B at 5 x 10(-6) M caused maximum marker release from the saturated dipalmitoyl lecithin liposomes, minimum release from the unsaturated dioleoyl lecithin liposomes, and an in-between response from egg lecithin liposomes. Nystatin at 2.5 to 4.0 x 10(-5) M induced appreciable marker release from all three types of sterol-free liposomes. The amphotericin B- a...

Psychiatric inpatients with tardive dyskinesia (TD) were treated with either lithium alone (n = 9) or with a combination of lithium and lecithin (n = 9) for 5 weeks in a double-blind, placebo-controlled experiment. A statistically significant but clinically unimportant improvement of TD occurred during both treatments. The addition of lecithin to lithium had no effect.
