Urinary hippuric acid, which decreased during the attack, increased as the patient recovered and was able to eat. The severity of her clinical condition correlated most closely to the plasma isovaleric acid concentration and urinary excretion of ketone bodies, lactic acid and 2-hydroxy-n-butyric ...

Hydroxyhippuric acid is also considered a microbial derived end-product and both originate from polyphenol metabolism by intestinal microflora. Feature #9 is another microbial-dependent metabolite, methyluric acid (Table 2). All three compounds are significantly elevated in patients taking metoprolol. ...
1. After administration of styrene to rat, phenaceturic acid, a new metabolite, was isolated. After administration of d8-styrene to rat, deuterium-labelled phenaceturic acid was excreted in the urine. 2. Two metabolic pathways are proposed, based on mass spectra of the deuterium-labelled phen...

The urinary methyl hippuric acid (MHA) level was analysed by using Shimadzu UV-Visible Spectrophotometer method. Results: The urinary Methyl hippuric acid level was significantly higher in petroleum station employees than in healthy individuals (p<0.001). Conclusion: The urinary MHA level is a ...
