zinc sulphate is currently used for treatment of zinc deficiency. its uptake by the body is poor, necessitating the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailability of zinc, several zinc complexes have been designed and synthesized using bidentate ligands of hydroxypyranones and hydroxypyridinones. elemental analysis in eac...

In this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. For CaSnO3 preparation ammonia was used as precipitation agent. The effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. By changing in Ca(Sal)2 as a new precursor different morphologies were obtained. Ligand as a capp...

after iron deficiency, zinc deficiency is the major micronutrient deficiency in developing countries, and staple food fortification is an effective strategy to prevent and improve it among at-risk-populations. no action has been taken to reduce zinc deficiency via flour fortification so far in iran, and little is known about the influence of zinc fortification of flour on serum zinc and the iro...

desferroxamine (desferal) is used tochelate iron in thalassemia, a disease of very high prevalence in various parts of lran. we have investigated intestinal zinc absorption in desferal-treated rats which, in pilot experiments, showed low serum levels of both iron and zinc. intraperitoneal administration of ten 0.5 g doses of desferal (one injection every other day) to male rats produced severe ...
