... peroxidation in both control and hyperoxaluric rats. A twofold increase in oxalate concentration was observed in the nucleus as well as the nuclear subfractions in hyperoxaluria. Hyperoxaluric rat kidneys showed increased H1 and oxalate binding activity, and the distribution of H1B was higher than...

... that received combined treatment. On pretreatment with vitamin E the observed increased urinary activities of the enzymes and oxalate, histopathological changes and the deposition of CaOx crystals by administration of CsA in hyperoxaluria were prevented suggesting that vitamin E could be supplemented to prevent...

... normal by 72 h after transplant. Rapid clearance of oxalate after transplant leads to transient hyperoxaluria until normal levels of serum oxalate are reached. 6 09 1993 17 12 2008 © 1994 S. Karger AG, Basel 1994 Copyright / Drug Dosage / Disclaimer Copyright: All rights reserved...

... intoxication. Despite urinary calcium excretion control, the danger of nephrocalcinosis in treated patients has been emphasized. It has recently been suggested that hyperoxaluria might be a causative factor of nephrocalcinosis other than calcium in phosphate-treated XLH patients. We measured urinary oxalate...

Vianello We describe the case of a patient in end-stage renal failure due to primary hyperoxaluria type I (PHI) who started hemodialysis in 1977and is still alive and active. The diagnosis...

...% in the trial with 100 g chocolate and reached the amounts found in cases with primary hyperoxaluria. The administration of ranitidine had no influence on oxalic acid absorption. The transient hyperoxaluria observed seems to be an important factor for the formation of calcium oxalate calculi in patients on risk...

...S.H. Morgan; P. Purkiss; R.W.E. Watts; M.A. Mansell In order to separate the effect of oxalate retention in primary hyperoxaluria with renal failure from that of excessive oxalate synthesis and to determine the optimum time for renal transplantation in primary hyperoxaluria, we have studied...

...P. Boer; J.A.C. Prenen; H.A. Koomans; E.J. Dorhout Mees The 14 C-oxalate clearance was determined in 13 healthy subjects and 22 patients with various diseases and varying degrees of renal functional impairment, including 5 patients with primary hyperoxaluria (PH). The clearances of oxalate (C ox...

... hyperoxaluria as urinary oxalate excretion greater than 2 SD above normal, 50% of stone-forming people were found to be hyperoxaluric. When stone formers were classified in normo- and hyperoxaluric, the prevalence of hypercalciuria, hyperuricuria, family history of stone disease and recurrencies in stone...

... and the urinary excretion of calcium. There is, however, a strong relationship between these parameters and the urinary excretion of oxalate which is slightly, but significantly, elevated in stone-formers compared with normals. It is concluded that this mild degree of hyperoxaluria may be much more important than...

...Ramasamy Selvam; Selvakumar Balakrishnan; Periandavan Kalaiselvi Proteins are thought to play a major role in stone formation and structurally abnormal proteins have been reported to be present in the urine of stone formers. This study was aimed to determine whether hyperoxaluria modifies...

... hyperoxaluria. Methods: Urolithiasis was induced in experimental rats by oral feeding 1% ethylene glycol (EG). The microsomes were carboxylated in presence of reduced vitamin K and COM binding activity was determined. Results: Microsomal proteins adsorbed maximally with COM crystals. On carboxylation...

.... Calcium nephrolithiasis Calcium oxalates Calcium phosphates Hypercalciuria Hyperoxaluria Hypocitraturia Calcium nephrolithiasis (CaNL) is the most common type of lithiasis in western countries, since calcium is the principal constituent of up to 70–80% of all renal stones. Under...
