A rapid headspace-gas chromatography (HS-GC) method was developed for the analysis of ethylene glycol and propylene glycol in plasma and serum specimens using 1,3-propanediol as the internal standard. The method employed a single-step derivitization using phenylboronic acid, was linear to 200 mg/dL and had a lower limit of quantitation of 1 mg/dL suitable for clinical analyses. The analytical m...

the effect of adding sodium stearoyl-2-lactylate (ssl) and propylene glycol (pg) (0 - 0.5 g/100g) to emulsifier gel formulation on the crumb and crust characteristics of barbari bread fortified with soy flour in order to optimize these characteristics were evaluated. the obtained results showed that addition of ssl caused an increase in the crumb and crust l* and cell density. the a*, b*, avera...

Hypokalemia is a fatal metabolic, pathological and induced disorder of Potassium, manifested by low serum levels generally encountered in lactating animals during thermal-stress. Currently Potassium given normal saline intravenously very slowly. This method costly, risky laborious. To study the effect oral administration 12 g elemental 200 ml Propylene glycol orally hypokalemic cows. After esti...

It has been found that propylene glycol vapor dispersed into the air of an enclosed space produces a marked and rapid bactericidal effect on microorganisms introduced into such an atmosphere in droplet form. Concentrations of 1 gm. of propylene glycol vapor in two to four million cc. of air produced immediate and complete sterilization of air into which pneumococci, streptococci, staphylococci,...

The main goal of this study was to describe the method of the synthesis of the dodecyl-, tetradecyl-, hexadecyl- and octadecyl-propylene glycol emulsifiers in the presence of selected anionic and nonionic surfactants. Acyl propylene glycol emulsifiers were produced by esterification of propane-1,2-diol (propylene glycol, PG) with C12:0-C18:0 fatty acids in the presence of anionic sodium dodecyl...

The delivery method of [continuous (CONT) vs. every other day or intermittent (INT)] a glucogenic precursor (GP) which was contained glycerin (500 g/kg), mono-propylene glycol (250 g/kg), calcium propionate (150 g/kg), niacin (1 g/kg) and sulfate-Co (350 mg/kg) on performance, selected blood metabolites and liver enzymes were evaluated. Twenty-four multiparous Holstein fresh cows were ...

To the Editor: We wish to substantiate the important observations of LeGatt and Tisdell (1) cautioning against the use of propylene glycol as an internal standard for quantifying ethylene glycol. A 32-yearold woman presented to our emergency department in an agitated state after the ingestion of multiple drugs in an attempted suicide. Gastric lavage and charcoal were administered as well as int...

<p class="Default"><strong>Background. </strong>Propylene glycol has been used successfully since the 1950’s for him acute and prophylactic treatment of ketosis in dairy cows however; its use poorly evaluated beef cattle meat sheep.<strong> Objective</strong>. Evaluate effects different doses propylene on productive parameters, blood metabolites ruminal parameters ...

Bovine rumen fluid was fermented anaerobically with 25 mM R-propylene glycol, S-propylene glycol, or glycerol added. After 24 h, all of the propylene glycol enantiomers and approximately 80% of the glycerol were metabolized. Acetate, propionate, butyrate, valerate, and caproate concentrations, in decreasing order, all increased with incubation time. Addition of any of the three substrates somew...
