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).

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.

Technetium-99m Labeled p-Aminohippuric Acid Analogues: Renal Function Agents

Journal of Pharmaceutical Sciences, 1989
A number of p-aminohippuric acid analogues were synthesized in order to develop clinically useful 99mTc-labeled radiopharmaceuticals for evaluation of renal function measurements. Stable 99mTc-labeled complexes were formed at pH 5.7 using a Sn(II) reduction method with all derivatives.

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.

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 ...

Nalidixic Acid: Intrarenal Distribution and Its Effect Upon Para-Aminohippurate Excretion

Journal of Urology, 1975
Studies performed on the intrarenal distribution of nalidixic acid in dogs show that this weak organic acid is indeed accumulated in the kidney, the highest concentration being attained in the cortex and followed in order by the outer medulla, papillae, and inner cortex. Our results also show that nalidixic acid produces significant changes in the para-
