background: pemphigus vulgaris is a life threatening, blistering skin disease. it is an autoimmune abnormality. due to involvement of oral cavity and pharynx, patients are at risk of nutrients deficiency. the aim of this study was to evaluate the status of selenium, copper, and zinc in these patients. methods: in a case-control study, 43 newly diagnosed pemphigus vulgaris patients were compared...

Concentrations of copper, zinc, mercury, and arsenic were measured in the muscle, gill and liver tissues of Coreius heterodon and Pelteobagrus vachelli collected from the rare and endemic fish nature reserve in the upper reaches of the Yangtze River. The concentrations of copper and zinc in the tissues of these two fish species were higher than those of mercury and arsenic. Highest metal concen...

The zinc and copper content of seventy-four foods was determined by atomic absorption spectrophotometry. Each of these foods was reported to have been consumed by practicing vegetarians. Legumes, seeds, nuts, whole grains, hard cheeses, and some nutritional supplements were found to be excellent sources of both zinc and copper. Vegetables, fruits, and their products were generally poor sources ...

AIM The main objectives of this study were for comparing the effect of batteries and deep litter rearing systems of domesticated Japanese quail, Coturnix coturnix japonica, on the concentration levels of cadmium, copper, lead, and zinc from the quail meat and offal in Ismailia, Egypt. MATERIALS AND METHODS A total of 40 quail meat and their offal samples were randomly collected from two main ...

OBJECTIVE The role of leptin in the acute stress response to extracorporeal circulation has been well documented, however, the relationship between leptin and zinc has not been investigated previously. We aimed to research the circulating leptin, zinc, and copper levels before, during, and after the extracorporeal circulation, and effect of preoperative zinc administration to these. METHODS T...

Wilson's Disease (WD) is an autosomal recessive disorder of copper metabolism resulting in a pathological accumulation of this metal, initially in the liver and later in other organs, mainly brain. Treatment with copper chelating agents and zinc salts results in a depletion of copper deposits and prevents or reverses the clinical manifestations. Copper deficiency may cause haematological and ne...

The essential metal copper, zinc and iron content in starved virgin and pregnant rat tissue has been studied. The copper content of the whole rat, which was actually increased in pregnant rats, decreased in starved pregnant rats. The differences were significant in 19-day pregnant rats. The total copper content of the conceptus was not affected by starvation. Iron distribution and net tissue co...

We studied the mechanisms by which excess copper exerts, and zinc mitigates, toxic effects on HepG2 cells. Survival and cell growth were reduced in media containing greater than 500 microM copper chloride for 48 h; LD50 was 750 microM. At 1,000 microM copper for 1 h, there was a general reduction of protein synthesis, and no recognizable changes in cellular ultrastructure. Incubation of cells w...

Serum zinc and copper concentrations of 156 healthy children (6-12 years old) were measured by the atomic absorption spectrophotometric method. The average serum zinc concentration was 92 +/- 13 mug/100 ml (mean +/- S.D.) with a range of 62-127 mug/100 ml. No statistically significant age or sex differences were found in serum zinc levels. The mean serum copper level was 109 +/- 17 mug/100 ml w...

Plasma copper and zinc in 20 ewes, healthy or infected with chronic postpartum metritis or mastitis, have been determined by atomic absorption spectrophotometry. Plasma protein profile was measured by electrophoresis on cellulose acetate plates, and albumin and ceruloplasmin were determined colorimetrically. For the ten initial days, plasma copper and ceruloplasmin increased in plasma zinc decr...
