This study evaluated, in vitro, the erosive potential of pediatric liquid medicines in primary tooth enamel, depending on the exposure time. Sixty deciduous incisors were randomly assigned to 4 groups (n=15), according to the immersion solutions: guaifenesin; ferrous sulfate; salbutamol sulfate and artificial saliva. The immersion cycles in the medicines were undertaken under a 1-min agitation,...

In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...

The aim of this study was to develop a method for the preparation of ferrous fumarate and folic acid oral dispersible tablets and their quality evaluation through HPLC and spectrophotometry. The formulation was optimized with dissolubility and dispersed uniformity as reference parameters by singlefactor and orthogonal experiments. The results exhibited that the optimal formulation contained: 18...

Ferrous carbonate was precipitated from the reaction of ferrous sulfate and sodium carbonate in an aqueous medium. The precipitate was calcined at different~eating rates (2, 5 and 10 °C/min, respectively) up to 500°C and the iron oxides produced were found to be magnetic. X-ray diffraction studies indicated the presence of gamma ferric oxide as a major phase in all the cases. It was found that ...

The title complex, [Fe(C(6)H(4)N(5))(2)(H(2)O)(2)], was synthesized by the reaction of ferrous sulfate with 5-(2-pyrid-yl)-2H-tetra-zole (HL). The Fe(II) atom, located on a crystallographic center of inversion, is coordinated by four N-atom donors from two planar trans-related deprotonated L ligands and two O atoms from two axial water mol-ecules in a distorted octa-hedral geometry. The Fe(II) ...

OBJECTIVES To assess the prevalence of anemia among children attending public preschools in Ilhabela, state of São Paulo, Brazil, and their response to a treatment regimen. METHODS Between 2007 and 2008, the weight, height, and hemoglobin levels of 667 children were measured in the school setting. Anemic children were prescribed a 12-week course of ferrous sulfate, and follow-up assessment vi...
