A sensitive and specific high-performance liquid chromatographic assay was developed for the simultaneous determination of p-aminohippuric acid (PAH), acetyl-p-aminohippuric acid (aPAH), and iothalamate in human plasma and urine. Plasma samples were prepared by protein precipitation with acetonitrile followed by evaporation, reconstitution in mobile ...

The metabolism of p-aminohippuric acid and p-acetylamino-hippuric acid
Clinica Chimica Acta, 1967Abstract p-Aminohippuric acid or p-acetylaminohippuric acid administered to patients orally instead of intravenously as a method to determine their kidney function was found to give erroneously low clearance values. It was found that these compounds lost the glycine moiety by hydrolysis in the alimentary tract and were converted in the tissues to ...

Synthesis of p-aminohippuric acid analog and its labeling by technetium-99m
International Journal of Radiation Applications and Instrumentation. Part A. Applied Radiation and Isotopes, 1989A procedure is described for the synthesis of p-[(bisacarboxymethyl)aminomethyl carbamino] hippuric acid (PAHIDA). The compound was identified by i.r. and NMR spectroscopy. A lyophilized complex was prepared and labeled with 99mTc. The purity of the preparation is better than 98%. The stability of the 99mTc-PAHIDA complex is achieved 8 h after labeling.

Clinical investigations of 99mTc–p-aminohippuric acid as a new renal agent
Nuclear Medicine Communications, 200999mTc-p-aminohippuric acid (PAH) is a new radiopharmaceutical rapidly secreted by the kidneys in a manner consistent with tubular secretion. A comparative study of renal scintigraphy and clearance with 99mTc-PAH, diethylene triamine pentaacetic acid (DTPA) and mercaptoacetyltriglycine (MAG,) was performed.99mTc-PAH was prepared from a lyophilized kit ...

Hexachloro-1:3-butadiene (HCBD) and potassium dichromate (Cr6+) are chemicals toxic for the pars recta and the pars convoluta, respectively. PAH accumulation takes place in the basolateral membrane of the proximal tubule and its impairment is a sign of damage of the membrane.

p-Aminohippuric acid transport into brush border vesicles isolated from flounder kidney
American Journal of Physiology-Renal Physiology, 1979p-Aminohippuric acid (PAH) transport was investigated in brush border vesicles isolated from renal proximal tubules of the winter flounder. Three characteristics of carrier-mediated transport were demonstrated: 1) unlabeled PAH inhibited the uptake of [3H]PAH; 2)[3H]PAH efflux from the vesicles was stimulated in the presence of unlabeled PAH in the ...
