Probiotics for the management of kidney stone disease
Kidney stones contain various combinations of chemicals, however, 80% consist of calcium oxalate. Oxalate in humans is either absorbed into the urinary tract and excreted in urine or degraded by gut bacteria. Oxalate-degrading gut bacteria play a critical role in human oxalate homeostasis, …

The isolation and partial characterization of rat kidney stone matrix induced by magnesium deficiency
… deficiency in rats has been employed to generate kidney stones in a relatively short period of time. Stones have been observed in situ and examined histochemically. Techniques have been devised for the isolation of the kidney stones and for the demineralization of the stones. The gross …

The effect of Ascorbic acid ingestion on the risk of calcium oxalate kidney stone formation
… of ascorbic acid on the risk of calcium oxalate kidney stone formation. Ten healthy male subjects (ages 20 to 30 years) participated in the study. Each was required to ingest a daily dose of 4 g ascorbic acid per day for a period of 5 days. Twenty-four hour urines were collected at various times …

The use of ¹H-NMR analysis of urine to discriminate between calcium oxalate kidney stone patients and healthy controls
NMR has been used to study the metabolites found in body fluids, like urine, in the past three decades. It has more recently been used to study a lare range of diseases and the toxicolgoical effect of drugs on animals, by looking at metabolite patterns in the urine. The major advanteges of using …

Evaluating oxalate-degrading Lactobacillus spp. for their ability to be used as probiotics in the treatment of kidney stone disease
Although the direct cause of kidney stone formation is not known, reports have suggested it is probably a multifactorial disease. Lactobacillus strains which potentially had increased ability to degrade oxalate were previously isolated from a healthy low kidney stone risk group. The aim of this …

Urinary prothrombin fragment 1 : a potential role-player in the protection of South African blacks from calcium oxalate kidney stone disease
The incidence of kidney stones amongst South Africa's black population is rare. This is in contrast to the white population, whose stone rate is similar to that in Western society. Urine composition alone does not account for these differences. This thesis presents a study of the inhibitory role of …

Investigation of the in vitro and in vivo effects of some herbal preparations on risk factors for calcium oxalate kidney stone disease
… Phyllanthus niruri, Orthosiphon stamineus and Cystone®) were investigated as potential therapeutic and prophylactic agents for kidney stone disease. These studies were executed in the context of the existence of a virtually stone-free (black) and a stone-prone (white) population group in South …

Modeling Uric Acid Kidney Stones Disease in D. melanogaster using RNAi and Dietary Modulation
… major predictor for gout and forming uric acid kidney stones is elevated uric acid in the serum and urine respectively. It is known that uric acid is an end metabolite of purine degradation in humans, but in other species from <em>D. melanogaster </em>to lower apes,<em> </em>uric acid can be …

Kidney stone rarity in South Africa's black population : investigation of the biochemical and physico-chemical properties of Tamm Horsfall Mucoprotein as a possible contributory factor
… in South African black and white healthy and stone—forn1ing male subjects. THP was isolated by salt precipitation, purified by column chromatography and verified by electrophoresis on SDS-polyacrylamide gels. MALDI-TOF mass spectroscopy was used to determine the molecular weights of the protein …

Studies of the effects of various lithogenic and antilithogenic dietry supplements on calcium oxalate kidney stone risk factors in South African black and white subjects
… groups have been reported, but the rarity of kidney stone disease in the black group remains a riddle. The studies described in this thesis were undertaken to address aspects of this phenomenon. Carbohydrate and oxalate-containing dietary agents were identified as being of interest since …

Investigation of the effect of hydroxycitric acid on urinary calcium oxalate risk factors for kidney stone formation in artificial urine: theoretical modelling and in vitro crystallisation experiments
… or urolithiasis, commonly known as kidney stones, is a common medical problem. Kidney stones are composed of different mineral types. Calcium Oxalate is the most common kind of stone. The principal aim of this research was to establish whether hydroxycitrate (HCA) affects and/or …

Characterization of the physiochemical and biochemical properties of the urinary protein bikunin in South African black and white subjects with respect to calcium oxalate kidney stone formation
… Western world are likely to suffer at least one kidney stone in their life. The incidence of kidney stone disease in South Africa is similar in white males; however stone occurrence in the South African black population is extremely rare. The difference between the incidences of kidney stones in …

Investigation of the role of dietary myo-inositol hexakisphosphate (phytate) on the relative risk of calcium oxalate kidney stone formation in black and white male South African subjects
… studies have shown that caJclum oxalate (CaOx) stone-formers have lower urinary concentrations of myo-inositol hexakisphosphate (phytate or IPe) than healthy individuals, that dietary intake of this substance leads to its increased urinary excretion and that it is an inhibitor of CaOx nucleation …
