Hydroxyethyl Starch Inhibits Endothelium-Derived Relaxation in Porcine Coronary Arteries
Pharmacology, 2008<i>Objective:</i> Hydroxyethyl starch (HES) solutions are widely used for fluid resuscitation. We studied the effects of HES on endothelium-dependent relaxation (EDR), especially on the endothelium-derived hyperpolarizing factor (EDHF). <i>Methods:</i> Four-millimeter-long rings of fresh porcine coronary arteries from the local ...

Hydroxyethyl derivatives of the amylopectin starch from waxy maize
Chemistry of Natural Compounds, 1975A gas-liquid chromatographic method has been used for analyzing the degree of substitution of a number of samples of hydroxyethylated partially hydrolyzed amylopection starch. A new method of plotting a calibration graph differing from that used previously is proposed.

Maize‐ or potato‐derived hydroxyethyl starches: is there any thromboelastometric difference?
Acta Anaesthesiologica Scandinavica, 2010Background: Hydroxyethyl starches (HES) could differ with regard to the origin, and the influence on the coagulation of the raw material is unknown. This study compared the effects of a new potato‐derived HES with a maize‐derived HES and two crystalloid solutions.Methods: Whole blood from 10 healthy individuals was diluted by 20% and 40% using either

Mass spectrometry of partially methylated alditol acetates derived from hydroxyethyl starch
Journal of Mass Spectrometry, 2000The degradation and derivatization of hydroxyethyl starch to partially methylated alditol acetates (PMAAs) allows its detection by gas chromatography/mass spectrometry. The derivatization was performed by permethylation of the carbohydrate, hydrolysis of the permethylated polysaccharide, reduction of the resulting monosaccharides to alditoles and ...

Cationic starch, cationic cellulose derivatives, and hydrophobically modified cationic cellulose were physically adsorbed from aqueous solution onto oppositely charged hydrophobic polyester (poly(ethylene terephthalate)) fabric and nonwoven, and this resulted in hydrophilic surface properties.

Pharmacology, 2010
<i>Background:</i> In a pilot study we could show that hydroxyethyl starch (HES) induced a significant reduction of endothelium-dependent relaxation (EDR) and the endothelium-derived hyperpolarizing factor (EDHF). In this follow-up study we investigated whether this effect of HES was dose-dependent and whether it could be replicated with ...

Russian Chemical Bulletin, 2014
Approaches to the synthesis of hydroxyethyl starch derivatives containing phenylpropanoic acid fragments with various degree of substitution were suggested. Esterification of hydroxyethyl starch in heterogeneous aqueous organic medium gave rise to the corresponding esters of ferulic, p-coumaric, and sinapinic acids.

Esters based on 2,6-diisobornylphenol carboxy-containing derivatives and hydroxyethyl starch were synthesized in order to obtain water-soluble forms of pharmacologically active substance 2,6-diisobornyl-4-methylphenol. Esterification of phenolcarboxylic acid derivatives with the polysaccharide was accomplished in heterogeneous aqueous organic medium or
