Quantitative determination of azure A in urine.
HE INTRODUCTION OF the carboxylic acid cation exchange Amberlite XE-96 (or IRC-50) Azure A resin’ as the medium for hydrogen ion exchange in place of the quininium exchange resin has simplified greatly the determination of gastric acidity without intubation (1). Solvent extraction and fluorimetry are no longer required. The amount of blue dye excreted in the urine is readily measured by visual ...
متن کاملThe determination of prostaglandin metabolites in human urine.
A method has been developed in which the human urinary prostaglandin metabolites are converted into stable prostanoic and prostanediotic acid homologues. The urine is reduced with sodium borohydride and the organic compounds, isolated with an Amberlite XAD-2 column, are treated with fuming hydrogen iodide, followed by treatment with zinc in methanolic hydrogen chloride, to yield dimethyl tetran...
متن کاملQuantitative determination of tryptophan metabolites (via kynurenine) in biologic fluids.
HE POSSIBILITY OF 1)ETERMINING QUANTITATIVF LY some products of tryptophan metabolism (1) has been examined previously by one of the authors. Paper chromatography was used as a tool for the separation of kynurenine, 3-hydroxykynurenine, anthranilic, 3-hydroxyanthranilic, kynurenic, and xanthurenic acids. The purpose of this paper is to report on the quantitative determination of these products ...
متن کاملOn the Quantitative Determination of Acetone in the Urine.’
Although a number of methods have been devised for the quantitative estimation of acetone in the urine, at the present time the method of Messinger,2 as modified by Huppert,s is the one most frequently employed, and is usually regarded as the most accurate one at our command.4 A recent paper by Folin5 offers the first satisfactory method for separately determining the acetone and diacetic acid ...
متن کاملNew colorimetric method for quantitative determination of protein in urine.
Total urinary protein is rapidly precipitated at room temperature by tannic acid. The tannic acid/protein precipitate, dissolved in aqueous triethanolamine/ferric chloride solution, gives a purple-violet color of high absorptivity. Absorbance at 510 nm is linearly related to concentration from 0.05 to 1.50 A for a protein content of 0.05 to 1.50 g/liter, and less than 5 mg/liter can be detected...
