“…The borosilicate glass test tubes of 2.5cm diameter and 20cm length were used as crystallizing vessels. In a single diffusion gel method, gel was set by mixing sodium meta silicate solution of density 1.03g/cm -3 was adjusted to a PH of 6 by adding 5% glacial acetic acid (11). Calcium chloride (0.1M) and manganese chloride (0.001M) one of the reactants was incorporated inside the gel.…”

Urinary stone disease is one of the major diseases in the human history. The human urinary calculi are mainly formed from calcium oxalate, Struvite and uric acid crystals. It is important for the physician and surgeon to distinguish the two types of hydrates of calcium oxalate mainly mono and di-hydrate. Manganese doped Calcium Oxalate Monohydrate (MnCaOxM) crystals were grown by silica gel method. Manganese is a trace mineral that is present in tiny amounts in the body. It is found mostly in bones and blood clotting factors. It is also plays a role in fat and carbohydrate metabolism. Manganese is also necessary for normal brain and nerve function. The grown crystals were characterized by FTIR, FT-Raman XRD, SEM-EDX, TGA/DTA analysis and UV-Visible analysis.

Abstract:The conditions for the gel growth of barium oxalate single crystals in silica gels were studied in this paper. We describe the growth mechanism, effect concentration of feed solution, interchanging of the reactants, the effect of temperature and detailed study of microstructures of barium oxalate single crystals. At higher concentration of feed solution dense fibers were observed. With interchanged feed solution precipitate and spherulites have been obtained. The effect of temperature on growth barium oxalate crystals showed that there was a decrease in nucleation density at higher temperature. The crystals growth were observed under the electron microscope which revealed that the crystal have needle and spherulites structures. We also report the FTIR studies of barium oxalate crystals.

“…Gel growth (in vitro) of a few urinary stone constituents and the inhibitory role played by some extracts or juices of natural products in crystal growth were studied earlier [20][21][22] . This technique has been successfully used to study the growth inhibition of calcium oxalate crystals [23] and calcium hydrogen phosphate dihydrate (CHPD), i.e., Brushite crystals [24] using herbal extracts of Tribulusterrestris Linn.…”

To investigate the inhibitory effect of lemon and orange juices on the growth of struvite crystals. Struvite crystals were grown by the single diffusion gel growth technique and the inhibitory effect of lemon and orange juices on the growth of struvitecrystals has been studied. With an increase in the concentration of lemon and orange juices, the weight of the formed crystals was gradually reduced from 2.49 g to 0.09 g (lemon juice) and 2.49 g to 0.21 g (orange juice) for the struvite crystals, respectively. The crystals harvested from the treated lemon and orange juices were characterized by Fourier Transform Infrared Spectroscopy (FTIR) to confirm the functional groups. Results obtained indicated that lemon juice has the potential to inhibit the formation of struvitecrystals as compared to orange juice. This study confirms that using lemon juice can promote the formation of ammonium magnesium phosphate hexahydratecrystals and reduce the nucleation rate of struvitecrystals, a major component of urinary stone.
