Urolithiasis is a stone disease known from ancient times, but still now the causes for the formation of the different kinds of stones are unknown. The high rate of recurrences of urinary stone disease provides a medical challenge which leads to social and economic problems of considerable magnitude and pursues the researchers to carry out in-vitro studies on these urinary stone crystals. The investigations were carried out to analyse the promotery/inhibitory effects of various allopathic medicines consumed normally for headache, fever, stomach disorder, diabetes etc. The investigations show that the urolithiasis is promoted due to the consumption of allopathic drugs.In this study the Cetapin XR, an allopathic medicine and Mathumagachooranam tablet, are taken for consideration. We have grown three struvitecrystals by adding these drugs separately with 10 mg concentration. The characterization such as powder XRD and UV-Vis spectral analysis are carried out.The crystallite size calculated from the XRD shows that Mathumagachooranam is of small size. The strain values are analyzed using Williamson Hall plot. Due to drug addition the considerable changes have been observed.

“…Inorganic phosphate compounds contain a large class of diverse materials whose application includes: catalysis, ion exchange, proton conductivity, food additive, fertilizer, detergent, fuel cell, intercalation chemistry, photochemistry, pigment, surface coating, bond and teeth [1][2][3][4][5]. They have attracted more and more interests on synthesis, crystallography, electro-optical material, morphology and so on [5][6][7][8][9][10].…”

Barium hydrogenphosphate, BaHPO4 was synthesized for the first time through simple and rapid method using BaCO3-H3PO4-NaOH, pH =9.0 at room temperature for 30 min. The studied BaHPO4 decomposed in a single well-defined stage via deprotonated hydrogenphosphate reactions, revealed by TG/DTG and DSC techniques. The calculated wavenumbers based on DSC peak were comparable with FTIR results, which support the breaking bonds of P-OH (HPO42-) in the deprotonated hydrogenphosphate reactions. The thermodynamic functions (ΔH*, ΔG*, and ΔS*) for the deprotonated hydrogenphosphate reactions calculated from DSC data indicate that the deprotonated HPO42- reaction occur a lower-energy pathway and spontaneous process. The FTIR, XRD and SEM data of the studied BaHPO4 and its decomposed product Ba2P2O7 are also reported.

“…Strontium hydrogen phosphate (SHP), calcium hydrogen phosphate (CHP) and barium hydrogen phosphate (BHP) are grown in silica gel medium at room temperature (Sundaramoorthi et al 2008). The next approach is to grow mixed crystal in silica gel medium at different environments, which contains two major elements (calcium, phosphate), and one inhibitor (magnesium).…”

Kidney stone consists of various organic, inorganic and semi organic compounds. Mineral oxalate monohydrate and di-hydrate are the main organic constituents of kidney stones. However, mechanisms leading to the formation of mineral oxalate kidney stones are not clearly understood. The effect of some urinary stone constituents such as ammonium oxalate, calcium citrate, proteins and trace elements were reported by us. The calcium magnesium hydrogen phosphate (CaMHP) crystals were grown in SMS gel medium which provides the necessary kidney stimuli growth medium. The growth processes were done by single diffusion method for different physical and chemical parameters. The pH range in which HPO 2 4 -ions dominates were considered which in turn is necessary for the growth of CaMHP crystals. In the present study, calcium magnesium hydrogen phosphate (CaMHP) crystals are grown in three different growth faces to attain the total nucleation reduction. As an extension of this research, many characterization studies have been carried out like XRD, FTIR, TGA, SEM and etching and the results are reported.
