Sažetak
The effect of Tamm-Horsfall protein isolated from urine of healthy subjects on calcium oxalate precipitation was studied in model systems of precipitation. The study was performed using following conditions: concentrations of calcium chloride 10 mmol/l, sodium chloride 150 mmol/l, oxalic acid 300 mumol/l ; pH 6.0, and temperature 310 K. The concentration of Tamm-Horsfall protein varied between 1-10 mg/l. The kinetics of calcium oxalate precipitation was observed by measuring the number and volume of particles in the suspension, and the precipitate composition by an optic microscope. In all the studied systems, the precipitate morphology corresponded to pure calcium oxalate monohydrate. Tamm-Horsfall protein was found to inhibit the growth of calcium oxalate monohydrate crystals and stimulate their aggregation in the given experimental conditions. Both effects were enhanced by increase in the concentrations of Tamm-Horsfall protein and were most pronounced at the concentration of Tamm- Horsfall protein of 10 mg/l.
