High Performance Liquid Chromatography Determination of Urinary Hippuric Acid and Benzoic Acid as Indices for Glue Sniffer Urine
A simple method for the simultaneous determination of hippuric acid and benzoic acid in urine using reversed-phase high performance liquid chromatography was described. Chromatography was performed on a Nova-Pak C18 (3.9 x 150 mm) column with a mobile phase of mixed solution methanol: water: acetic acid (20:80:0.2) and UV detection at 254 nm. The calibration curve was linear within concentratio...
متن کاملStudies in the Synthesis of Hippuric Acid in the Animal Organism. Ii. the Synthesis and Rate of Elimination of Hippuric Acid after Benzoate
The question of the extent of the ability of the human organism to detoxicate benzoic acid by conjugation with glycocoll and elimination as hippuric acid in the urine has frequently been raised. Lewinsk? observed in the urine of men to whom 12 to 20 grams of benzoic acid had been given in small doses during t,he course of twelve hours, neither free benzoic acid nor benzoyl glycuronates. With la...
متن کاملBenzoylated Amino Acids in the Animal Organism. Iii. a Method for the Determination of Hippuric Acid* and a Study of the Synthesis of Hippuric Acid in Rabbits.? by Wendell H. Griffith
In 1877 Salkowski (1) noted the presence of a reducing substance in the urine of rabbits following the administration of sodium benzoate. Later Magnus-Levy (2) reported that this substance was benzoyl glycuronic acid and stated that less was found in the urine of rabbits than in the urine of dogs and sheep. At the present time it is the general assumption that rabbits detoxicate ingested benzoi...
متن کاملEvaluation of Toluene Exposure in Workers at Industrial Area of Sidoarjo, Indonesia by Measurement of Urinary Hippuric Acid
Background: Toluene is a harmful substance still being used as a solvent and catalyst in many industries that can increase the level of urinary hippuric acid (UHA). This study was designed to examine the level of toluene and UHA among workers of industrial site in seven companies in Sidoarjo, Indonesia and to analyze the risk factors for abnormal UHA. Methods: This study was an analytical cross...
متن کاملA Sensitive Simultaneous Determination of Uric Acid, Norepinephrine and Indomethacin using a Cadmium Sulfide Nanoparticles/Multi-Walled Carbon Nanotubes Modified Gold Electrode
In this study a novel method was developed to fabricate cadmium sulfide nanoparticles/multiwalled carbon nanotubes composite modified gold electrode (CdSNPs/MWCNTS/AuE) to measure trace amounts of norepinephrine(NE), indomethacin (IND), and uric acid (UA) simultaneously. Electrochemical investigations were carried out using cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chron...
