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...

  Abstract   Objective: To determine the effect of oral zinc sulfate supplementation given with   coamoxiclav when compared with coamoxiclav alone for treatment of otitis media   with effusion (OME). The efficacy of the drug was assessed 3 and 6 weeks after administration .   Methods: In a double-blind, randomized trial 4 to 14 years old children with OME   who referred to ear, nose and throat ...

We investigated the effect of locally applied zinc on the healing of partial-thickness skin wounds in the domestic pig using two zinc compounds (zinc oxide and zinc sulfate) in two different vehicles (a gauze compress and a collagen sponge). The rate of re-epithelialization was determined morphometrically 48 and 64 hr after infliction of standardized square wounds (4.8 cm2 and 400-microns deep)...

Zinc sulfate is a known olfactory toxicant, although its specific effects on the olfactory epithelium of zebrafish are unknown. Olfactory organs of adult zebrafish were exposed to zinc sulfate and, after 2, 3, 5, 7, 10 or 14 days, fish were processed for histological, immunohistochemical, ultrastructural, and behavioral analyses. Severe morphological disruption of the olfactory organ was observ...

In 1948, Duggan and Luck (1) observed that certain organic anions in appropriate concentrations prevented the rise in viscosity of bovine serum albumin caused by 6 M urea. Among the anions studied, dodecyl sulfate was found to be the most effective. In 1957, Markus and Karush (2) showed that the rise in levorotation of human serum albumin caused by 6 M urea could also be prevented or reversed b...

The objective of this study was to compare zinc sources and levels of supplementation on laying hen performance. Bovan White Leghorn hens were fed one of six dietary treatments in a 2x3 factorial arrangement consisting of two zinc sources (Availa®Zn or zinc sulfate) and three levels (40, 80, or 120 ppm). Treatments were randomly assigned to 48 cages with five hens/cage. Blocks provided eight re...

to study the effect of type and different nitrogen fertilizers on controlling egyptian broomrape, field and greenhouse studies based on randomized complete block with three replications, were conducted at ferdowsi university of mashhad. greenhouse study treatments were consisted of ammonium nitrate, ammonium sulfate and urea each of which applied at four rates (75, 150, 300 and 350 kg/ha). fiel...
