Further R. aquatica root also claimed to have diuretic effect 24 and diuretic effects

may also reduce stone development when total fluid intake and output increased, and such effects have been attributed to several herbal preparations. Herbal extracts may contain substances that inhibit the growth of CaOx crystals. This property of plants may be important in preventing kidney stone formation; CaOx crystals induced by urinary macromolecules was less tightly bound to epithelial cell surfaces, which are then excreted with urine.32 The extract may also contain substances that inhibit CaOx crystal aggregation; the agglomeration of particles is a critical step in urinary stone formation, as larger crystals

are less likely to pass spontaneously in the urinary tract.33 If the extract keeps CaOx particles dispersed in solution they are more easily selleck compound eliminated. The aqueous extract of R. aquatica root have inhibitory Bortezomib solubility dmso effect on CaOx crystallization thus may be beneficial in the treatment of urolithiasis but there is a need of detailed investigation in elaborated preclinical experimentations and clinical trials to establish the use of plant as antiurolithiatic agent. All authors have none to declare. The authors are very grateful to the University Grants Commission New Delhi (UGC letter No: F.No.39-434/2010 (SR)) for financial support of this major because research project work. “
“Nanotechnology can be defined as the design, synthesis, and application of materials and devices whose size and shape have been engineered at the nanoscale.1 It exploits

unique chemical, physical, electrical, and mechanical properties that emerge when matter is structured at the nanoscale. One of the most important aspects in nanotechnology relies on the synthesis of nanoparticles with well-defined sizes, shapes and controlled monodispersity. One of the major challenges of current nanotechnology is to develop reliable and non-toxic experimental protocols for the synthesis of nanoparticles with regards to non-toxic, clean and eco-friendly.2 Biotechnological route has emerged as a safe and alternative process in synthesis of nanoparticles by employing ambient biological resources. Perusal of studies reported by far express biological synthesis of nanoparticles from simple prokaryotic Libraries organism to multi cellular eukaryotes such as fungi and plants.3, 4, 5 and 6 The adaptation to heavy metal rich environments is resulting in microorganisms which express activities such as biosorption, bioprecipitation, extracellular sequestration, transport mechanisms, and chelation. Such resistance mechanism forms the basis for the use of microorganisms in production of nanoparticles.
