PURPOSE To investigate the aqueous humor, lens, and serum concentrations of zinc, iron, and copper in patients with pseudoexfoliative cataract and compare with patients who have senile cataract without pseudoexfoliation. METHODS Twenty-five patients with pseudoexfoliative cataract and 25 patients with senile cataract as control group were enrolled in the study. Samples from aqueous humor, ser...

The concentrations of zinc, copper, cadmium and lead in surface water, sediments and two native snail species, Bellamya bengalensis and Melanoides tuberculata from Latipada reservoir were determined. The concentrations of cadmium and lead in surface water were higher than the WHO recommended limits for drinking water standards; where as those of zinc and copper were within the permissible limit...

patients and methods serum zn and cu level of 43 patients with brucellosis (34 men and 9 women) were compared with 43 matched healthy controls. serum micronutrient concentrations were measured by automatic absorptive spectrophotometry. results mean serum cu concentration was significantly higher in subjects with brucellosis when compared with agematched healthy controls (p<0.05). mean serum zn ...

Concentrations of heavy metals, pH, and particle size distribution parameters were measured in Dragica stream and Djetinja River water receiving wastewaters from copper rolling mill industry, Sevojno. The concentrations of copper, zinc, lead, and mercury were determined for water samples collected in summer 2009. It was found that Copper Rolling Mill Sevojno was the significant source of water ...

Cobb 500 broilers were fed diets that were zinc deficient (35ppm), supplemented with 70ppm zinc sulfate, or 70ppm zinc sulfate + 35ppm organic zinc (MINTREXTM Zn or zincmethionine). Half the birds were given a coccidiosis vaccine (ADVENT® coccidiosis control) at day of age, and challenged with all three species on day 24. MINTREX Zn and zinc-methionine both significantly increased intestinal br...

determination of trace elements in food is of great importance, as some of them have nutritional significance, whilst others are toxic. long-term exposure to low levels of toxic metals could be important, especially in relation to children. differential pulse anodic stripping voltammetry (dpasv) is applied to simultaneous determination of lead, cadmium, copper and zinc in dry ash infant formula...

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...

Background: Contamination of the environment due to heavy metals is a major concern to human life and the environment. This study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in Arak, Iran. Methods: Four industrial estates were considered for the experimental design, including Arak 1, Arak 2, Arak 3, and Ghotbe Sanaati. For prelimin...

The aims of this study were to evaluate zinc, copper, and iron concentrations in the transitory milk of Korean lactating mothers and to investigate the relationship between these concentrations and maternal diet. Human milk samples were collected between 5 and 15 days postpartum from 96 healthy, lactating mothers in postpartum care centers in Seoul, Korea. Dietary intake during lactation was de...
