... interventions. Some data suggest that increased oral magnesium (Mg) intake decreases recurrent calcium oxalate stone formation by lowering intestinal oxalate absorption and/or binding urinary oxalate. In this study, we tested the hypothesis that elevated Mg content in the diet would reduce urine SS and CaOx...

...R. Selvam; M. Adhirai The in vivo effect of cyclosporin A (CsA) on renal calcium oxalate (CaOx) crystal retention in experimental hyperoxaluric rats was investigated. Further, the effect of pretreatment of vitamin E on the above conditions was also studied. Male Wistar rats were divided into two...

... The possibility of more than one urinary protein being simultaneously associated with calcium oxalate (CaOx) crystallization in vivo was investigated by examining the localization of Tamm-Horsfall protein (THP) and osteopontin (Opn) in a rat model of nephrolithiasis. CaOx crystal deposits were...

... and Urinary Oxalate Excretion Key Words Calcium oxalate Plasma oxalate Hyperoxaluria Kidney transplant Abstract Serum levels of oxalate are elevated in uremic patients on dialysis. The effect of living related donor kidney transplants on serum and urine oxalate levels was studied in 8 patients. Serum...

... of renal stone formation. Among the studied admixtures, citrate was determined as the most effective substance preventing the phosphate particle formation. Indeed, in the presence of citrate, some calcium oxalate monohydrate crystals were found. Pyrophosphate induced the formation of calcium oxalate...

...M.H. Gault; M.D. Paul; L. Longerich To compare the frequency of urine infection in calcium oxalate and calcium phosphate stone formers, we reviewed charts from patients whose last renal stone submitted for analysis was predominantly composed of calcium phosphate in 118 and of calcium oxalate in 223...

...A. Conte; P. Roca; C. Genestar; F. Grases Uric acid is implicated in calcium oxalate kidney stone formation. Conspicuously so far, two hypotheses have been proposed: direct induction of calcium oxalate precipitation by uric acid, and uric acid as anti-inhibitor by binding urinary glycosaminoglycans...

...W.G. Robertson; M. Peacock Hypercalciuria is common in patients who form calcium oxalate urinary stones and is considered by many to be the cause ofthe disorder. This review shows that there is little relationship between either the rate of stone-formation or calcium oxalate crystalluria...

...Takahiro Yasui; Motohiko Sato; Keiji Fujita; Yasunori Ito; Shintaro Nomura; Kenjiro Kohri Background: The inhibitory effect of allopurinol on calcium oxalate urolithiasis has been reported, but its effect on stone matrix proteins has not been studied in vivo. To clarify the effect of allopurinol...

... endocytosis by Madin-Darby canine kidney (MDCK) cell cultures. Phyllanthus niruri Calcium oxalate Madin-Darby canine kidney cells Endocytosis Renal stone MDCK cells obtained from the American Type of Culture Collection from passages 75 to 90 were cultured in Dulbecco’s modified Eagle...

...JohnC. Lieske; Sergio Deganello; F.Gary Toback Background: Renal tubular fluid in the distal nephron is supersaturated with calcium and oxalate ions that nucleate to form crystals of calcium oxalate monohydrate (COM), the most common crystal in renal stones. How these nascent crystals are retained...
