background: there have  been  several studies  done  on the role of metals in the occurrence  of multiple sclerosis (ms) disease, but their roles have not been confirmed yet. because of the lack of information on this issue, this study compared  the  serum  level  of  copper and zinc in ms patients with their levels in a control group. methods: this  was  an  analytical,  cross-sectional  study...

To investigate the impact of calcium, magnesium, zinc, and copper in blood and seminal plasma on semen parameters, 107 fertile and 103 subfertile males provided a standardized blood and semen specimen. Total calcium and magnesium concentrations were determined with colorimetric end point assay procedures. Zinc and copper were determined by flame atomic absorption spectrophotometer (AAS). Semen ...

Zinc deficiency is clearly teratogenic in animals (1). The catabolism of maternal tissues during pregnancy, however, seems to protect the fetus from the teratogenic effects of hypozincemia (2). In humans, most evidence suggesting the importance of zinc during pregnancy comes from patients with acrodermatitis enteropathica, an inherited severe zinc deficiency state. These patients have spontaneo...

apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. infants and young children are very susceptible to amount of trace elements. copper and zinc are two elements that add in infant food. lead and cadmium are heavy metals that enter to food chain unavoidably. dpasv is a benefit and applicable method for measurement of trace elements in food produc...

Wilson’s disease (WD) is an inherited autosomal recessive disorder that lead to copper accumulation in the liver, brain, cornea, and other organs [1]. WD is treatable by life-long decoppering therapy with the aim of removing excess copper and preventing re-accumulation. This is accomplished with two main groups of drugs: chelating agents, including d-penicillamine (DPA) and trientine, that prom...

Introduction: Copper and zinc play a key role in oxidative reactions and in vivo studies have shown their different effects. In this study we examined the influence of exposure to copper and zinc on catalase and superoxide dismutase (SOD) activities in erythrocytes, total serum antioxidant capacity and malondiadehyde (MDA) production of copper industry workers. Methods: In the present study...

In plants, copper is an essential micronutrient required for photosynthesis. Two of the most abundant copper proteins, plastocyanin and copper/zinc superoxide dismutase, are found in chloroplasts. Whereas plastocyanin is essential for photo-autotrophic growth, copper/zinc superoxide dismutase is dispensable and in plastids can be replaced by an iron superoxide dismutase when copper is limiting....

Background: Intra uterine devices (IUDs) are among the most commonly used contraception methods around the world. The most common form of IUDs used in Iran, is IUD Copper T-380A. As recently there is great emphasis on the role of blood zinc levels on general health conditions, this study was performed to assess the effects of IUD T-380-A insertion on zinc and also copper serum levels. Materials...

Zinc and copper were histochemically localized in rat ocular tissues. Zinc was demonstrated by the dithizone method, and copper by the rubeanic acid and rhodanine methods. The retinal photoreceptor's outer segment showed the presence of zinc, but no zinc reaction was seen in other parts of the retina or other ocular tissues, even in rats fed excess zinc. It seems that photoreceptor cells contai...
