Effectof Albuminand Lamellar Bodieson FluorescencePolarizationof AmnioticFluid
ثبت نشده
چکیده
Using a probe and procedure developed for the Abbott TOx analyzer, we investigated the influence of albumin on fluorescence polarization of amniotic fluid. Polarization readings increased when albumin was added to either “mature” or “immature”amnioticfluids. Albumin added to a fraction rich in lamellar bodies (10 000 x g pellet) greatly increased polarization readings, but albumin added to the lamellarbody-free fraction resulted in only small increases. Adding increasing amounts of the lamellar-body-rich fraction from mature and immature pools to a constant amount of albumin decreased the polarization readings. We saw no correlation between amniotic fluid polarization and albumin concentration but found a significant correlation between polarization values and either total extractable phospholipids (r = 0.725, P <0.001) or the ratio albumin/total extractable phospholipids (r = 0.784, p <0.001). The concentration of albumin in amniotic fluid was variable and correlated poorly with gestational age.

Characterizationof AmnioticFluid LametlarBodiesby Resistive-PulseCounting:Relationshipto Measuresof Fetal Lung Maturity
Resistive-pulsecounting studies of amniotic fluid lamellar bodies are presented and demonstrate a strong concordance with the predictions of accepted measures of fetal lung maturity. Uncentrifuged as well as centrifuged specimens could be evaluated, because cells and debris are rejected electronically. The technique is not affected by bilirubin or debris of lysed whole blood, and only mildly by...

The interest to nanoobjects is mainly attracted by the fact that their properties (and also biological in particular interest to the project) differ drastically from the properties of either bulk material or constituent molecules. The fundamental task is correlation between structure of the nanoparticles and their interaction with surrounding media. The aim of project is a study of interaction ...
