Net absorption of amino acids by portal-drained viscera and hind half of beef cattle fed a high concentrate diet.

Journal of Animal Science, 1985
Two experiments were conducted to measure the effect of level of feed intake on net amino acid absorption by portal-drained viscera of six beef heifers with catheters in a mesenteric vein, portal vein and iliac artery (Exp.

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 ...

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. Scand. 121: 171 : 1917) claim to have demonstrated 110 relative magnitude, but generally lower PXH, either in plasma or in urine, after oral than those observed by Hamburger 8r administration of 4 grams of

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 ...

Drug-induced Fanconi's syndrome.

American Journal of Kidney Diseases, 2003
Fanconi's syndrome (FS) was first described by Lignac in 1924. Associated with numerous varieties of inherited and acquired conditions, FS is characterized by a generalized transport defect in the proximal tubules, leading to renal losses of glucose ...

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.

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.

Renal arginine metabolism in fasted rats with subacute short bowel syndrome.

Clinical science, 1998
1. Arginine can be produced in the kidney from citrulline. An important source of circulating citrulline is the intestinal breakdown of glutamine. Consequently, partial enterectomy leads to decreased plasma citrulline levels. The aim of the present study
