To investigate the physiological responses of sunflower (Helianthus annuus L., Alstar hybrid) to water stress under different levels of zinc fertilizer, an experiment was conducted at the Isfahan Agricultural Research Center, Isfahan, Iran, during 2008 and 2009 using a randomized complete block design within a split plot layout with three replications. Five irrigation treatments used in thi...

Sir: While writing my article for this journal titled ‘‘Zinc lozenges as cure for the common cold – a review and hypothesis” [1], I reflected upon the long 25-year history of zinc in treating colds, and also remembered that the history of use of zinc to treat croup in infants and young children was much longer. The first published use that I found for treating croup with zinc was in 1899; yes, ...

an experiment was conducted to optimize consumption of zinc and evaluate of zinc effects on quantitative and qualitative traits of winter wheat under saline soil condition. it was done by three replications in randomized complete block design. the experiment had four treatments as control without zn, 40 kg.ha-1 zn as znso4, 80 kg.ha-1 zn as znso4 in soil and 120 kg.ha-1 zn as znso4 in soil. ele...

Type 2 diabetes mellitus is a chronic illness causing considerable morbidity and mortality. Enormous advances have been made in medical care but more people are still having tendency to use herbal or alternative remedies. This study is a randomized, controlled trial on type 2 diabetic patients. The subject consisted of 60 patients divided randomly into three groups and supple-mented daily with ...

background: since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. the aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of mercuric chloride (hgcl2), lead chloride (pbcl2) and zinc sulfate (znso4) pollutan...

Background: The generation of reactive oxygen species (ROS) in the male reproductive tract has become an actual concern because of their probable noxious effects, at high levels, on physical properties of sperm quality. ROS are extremely reactive oxidizing agents, which a member of the class of free radicals. It was found that uric acid can act as an essential water soluble antioxidant and ther...

Objective: The aim of this study was to evaluate the effect of zinc and magnesium supplementation on glycemic control and serum insulin in type 2 diabetic patients. Materials and Methods: In this randomized clinical trial 70 diabetic patients who referred to Yazd Diabetes Center were selected. Subjects received 500 mg/day magnesium oxide or 100 mg/day zinc sulfate randomly for 8 weeks. At th...

inc alloy electrodeposits are finding increased acceptance as improved replacements for conventional electrogalvanized finishes. Zinc-nickel appears to be experiencing the most widespread use, although zinc-cobalt and zinc-iron also have well-defined market shares. The zinc-manganese system has not been widely reported; however, some investigators have examined its corrosion resistance, polariz...

Effects of zinc sulfate (0 vs 1,142 ppm supplemental zinc from zinc sulfate) and feeding frequency (1 x vs 12x daily) on ruminal protozoa numbers, fermentation patterns and amino acid passage were investigated using four ruminally and abomasally cannulated mature Jersey steers in a 4 x 4 Latin square experiment. Steers (530 kg) were fed a 50:50 roughage:concentrate diet at 1.5 times their NEm r...
