| Popis: | The recommended conservative treatment of hyperoxaluria is mainly based on hyperhydration and ingestion of inhibitors of crystallization. In accordance with this context, the aim of this study was to determine the in vitro effect of Hordeum vulgare on calcium oxalate crystallization oxalo-dependent. The crystallization of calcium oxalate monohydrate in supersaturated aqueous solution at 37 °C, was followed in a model turbidimetric continuous in a closed system. The proposed model is very good reproducibility (CV < 10%), crystallization was monitored continuously in the presence of Hordeum vulgare at different concentrations (0.0625 to 1 g/L). The comparison of turbidimetric parameters, that characterize the growth stage of monohydrated oxalate calcium crystals and observation of the crystals obtained at the end of crystallization into scanning electron microscopy, have been able to demonstrate the inducing effect of Hordeum vulgare to 0.0625 g/L and a slight inhibitory effect at the others concentrations. |
