Urinary calcium oxalate crystal growth inhibitors.
Calcium stones occur because renal tubular fluid and urine are supersaturated with respect to calcium oxalate and phosphate. The process of stone formation includes crystal nucleation, growth, aggregation, and attachment to renal epithelia. Urine contains macromolecules that modify these processes and may protect against stone formation. Attention has focused especially on inhibitors of crystal...
متن کاملNormal calcium oxalate crystal growth inhibition in severe calcium oxalate nephrolithiasis.
Urine from mammalian kidneys is regularly supersaturated with respect to calcium oxalate monohydrate, the most common solid phase in human nephrolithiasis, and also inhibits the nucleation, growth, and aggregation of calcium oxalate crystals. Nephrolithiasis is often associated with increased supersaturation, and it is assumed that this increase overbalances the inhibition effects, causing ston...
متن کاملIsolation from Human Calcium Oxalate Renal Stones of Nephrocalcin , a Glycoprotein Inhibitor of Calcium Oxalate Crystal Growth
We have determined that the organic matrix of calcium oxalate kidney stones contains a glycoprotein inhibitor of calcium oxalate crystal growth (nephrocalcin) that resembles nephrocalcin present in the urine of patients with calcium oxalate stones and differs from nephrocalcin from the urine of normal people. Pulverized calcium oxalate renal stones were extracted with 0.05M EDTA, pH 8.0; nephro...
متن کاملExtracellular cyanobacterial substances inhibit microbial growth.
Cyanobacteria are able to produce extracellular substances with different biological activities and behaviors. The marine cyanobacteria Anabaena sp. strain Hi 26 and Oscillatoria subtilissima strain Bo 62 cause significant color changes in their growth media, while viscosity of the medium is influenced by Rivularia sp. strain Bo 85 and Oscillatoria limnetica strain Flo 1. Sterile-filtered media...
متن کاملMolecular modulation of calcium oxalate crystallization.
Calcium oxalate monohydrate (COM) is the primary constituent of the majority of renal stones. Osteopontin (OPN), an aspartic acid-rich urinary protein, and citrate, a much smaller molecule, are potent inhibitors of COM crystallization at levels present in normal urine. Current concepts of the role of site-specific interactions in crystallization derived from studies of biomineralization are rev...
