Urinary metabolites levels in workers exposed to chlorobenzene.
Chlorobenzene is a colorless volatile compound widely used as an organic solvent or a chemical intermediate. There is, however, a potential risk for people engaged in the manufacture and the handling of this compound. The threshold limit value of the time-weighted average (TLV-TWA) for chlorobenzene in air has been set at 75 ppm (350 mg/m3).1) Animals exposed to chlorobenzene excrete this compo...
متن کاملIdentification of urinary metabolites of isoprene in rats and comparison with mouse urinary metabolites.
Isoprene, a major commodity chemical used in production of polyisoprene elastomers, has been shown to be carcinogenic in rodents. Similar to findings for the structurally related compound butadiene, mice are more susceptible than rats to isoprene-induced toxicity and carcinogenicity. Although differences in uptake, and disposition of isoprene in rats and mice have been described, its in vivo bi...

Isolation and identification of urinary metabolites of kakkalide in rats.
Kakkalide is a major isoflavonoid from the flowers of Pueraria lobata (Willd.) Ohwi, possessing the protective effect against ethanol-induced intoxication and hepatic injury. The metabolism of kakkalide was investigated in rats. Thirteen metabolites were isolated by using solvent extraction and repeated chromatographic methods and identified by using spectroscopic methods including UV, IR, mass...
متن کاملSpectrophotometric estimation of urinary taurine.
The amino-acid taurine has been shown to be a normal urinary constituent (Dent, 1948). Employing a quantitative chromatographic technique a diminished taurine excretion in cystinuria (Stein, 1951) and in Wilson's disease (Stein, Bearn, and Moore. 1954) has been detected. An increased taurine excretion. on the other hand, has been used as a sensitive index of minor liver damage in infectious hep...
