99Tcm-p-aminohippuric acid as a new renal agent

Nuclear Medicine Communications, 1999
99Tcm-p-aminohippuric acid (99Tcm-PAH) is a new renal radiopharmaceutical prepared from a lyophilized kit by the addition of sodium pertechnetate (Na99TcmO4). Each vial contains PAH, the calcium trisodium salt of diethylenetriamine pentaacetic acid (CaNa3DTPA) and stannous chloride (SnCl2.2H2O) in an inert atmosphere. It is a stable radiopharmaceutical

Clearance of para-aminohippuric acid in wethers consuming locoweed

New Zealand Veterinary Journal, 2005
To validate the use of para-aminohippuric acid (PAH) as a marker for measuring blood flow in wethers consuming a mixed diet of locoweed and blue grama hay.Fourteen sheep, stratified by bodyweight (BW), were assigned to one of three treatments: 0.8 mg swainsonine (SW)/kg BW (HI), 0.2 mg SW/kg BW (LO), and no SW (Control).

Simultaneous determination of p-aminohippuric acid, acetyl-p-aminohippuric acid and iothalamate in human plasma and urine by high-performance liquid chromatography

Journal of Chromatography B: Biomedical Sciences and Applications, 1998
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, 1967
Abstract 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 ...

p-Aminohippuric acid accumulation in kidney slices in cloudy swelling

Experientia, 1959
L'incorporazione dell'acidop-aminoippurico nelle sezioni di rene di ratto e diminuita nel rigonfiamento torbido provocato dal trattamento parenterale con tossina stafilococcioa, con dinitrofenolo o con tiroxina. Tutti questi trattamenti provocano anche dissociazione delle fosforilazioni dalle ossidazioni.

Clearance Determinations After Oral Administration of Para-Aminohippuric Acid [PDF]

Scandinavian Journal of Clinical and Laboratory Investigation, 1950
1) The substance was absorbed and demonstrable in both plasma and urine. 2) The concentrations were of the same Brun, IIilden & Raaschou (.lcta Yed.

THE EFFECT OF PARA-AMINOHIPPURIC ACID ON PLASMA CONCENTRATION OF PENICILLIN IN MAN [PDF]

Journal of the American Medical Association, 1944
Since the original announcement by Beyer, Peters, Woodward, Verwey and Mattis1three reports have been submitted for publication or appear in the literature to the effect that when sodium para-aminohippurate and penicillin were administered simultaneously the former compound competed with penicillin for the same renal tubular excretory mechanism.

Probenecid infusion in mares: Effect on para-aminohippuric acid clearance

American Journal of Veterinary Research, 1988
SUMMARY Para-aminohippuric acid (paha, 0.1 mg/min/kg of body weight) was infused iv into 2 mares, followed by concurrent iv infusion of paha and probenecid (0.075, 0.15, 0.25, or 0.35 mg of probenecid/min/kg). Probenecid infusion reduced the clearance of paha at serum probenecid concentrations > 55 μg/ml.

Clinical investigations of 99mTc–p-aminohippuric acid as a new renal agent

Nuclear Medicine Communications, 2009
99mTc-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 ...

Untersuchungen �ber die Para-Aminohippurs�ure-Clearance in Acidose [PDF]

Naunyn-Schmiedebergs Archiv f�r Experimentelle Pathologie und Pharmakologie, 1965
Die Clearance von Para-Aminohippursaure (PAH) und von Kreatinin wurde an narkotisierten Hunden bei niedrigem Harnflus bestimmt. Durch i.v. Infusion von Bicarbonatlosung bzw. von verdunnter Salzsaure wurde das Harn-pH systematisch verandert. Es fand sich keine Abhangigkeit der Clearancewerte vom Harn-pH.
