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...

Serum level of zinc, copper, β-carotene, vitamin A, and concentrations of Zn and Cu in hoof of 97multiparous Holstein dairy cows with different locomotion scores (LSs) were evaluated. Simultaneously, Znand Cu concentrations of close up, fresh and high yielding cattle rations were 77, 94, 75 and 31, 28, 22 ppm, respectively. Based on LSs, despite normal serum copper levels in all three groups, w...

1. Distribution of zinc between the metalloprotein alpha 2-macroglobulin and albumin was determined in samples of serum obtained from twenty-three women in their third trimester of pregnancy and eighteen women who were not pregnant. 2. The decrease observed in total serum zinc in the group of pregnant women could be accounted for in large part by a decreased concentration of albumin-bound zinc....

introduction: neonatal jaundice is the most common cause of hospitalization.animal study demonstrated a decrease in serum bililrubin level after zinc treatment in hyperbilirubinemic rats. the objective of this study was the investigation of serum zinc level in the neonates with idiopatic .   materials and methods: a case-control study was undertaken on 263 neonates in a neonatal intensive care ...

BACKGROUND Food acidulants, β-carotene-rich vegetables and sulfur compound-rich Allium spices are known to improve zinc bioaccessibility from food grains. This animal study evaluated the positive influence of these promoters of zinc bioaccessibility on zinc status during zinc repletion in Wistar rats previously rendered zinc-deficient by feeding a zinc-deficient semi-synthetic diet for 4 weeks....

background & aim: in some studies, changes in trace elements of abuse of addictive substances have been mentioned. due to the effects of trace elements on the immune system and their effects on susceptibility to infectious agents, the purpose of this study was to investigate the effect(s) of morphine dependency on the concentration of trace elements (copper, zinc and manganese) levels in serum ...

Febrile convulsions (FC) are the most common neurologic disorder in children 6-60 months of age. Zinc (Zn) and copper (Cu) play role as cofactors in more than 300 enzymatic activities significantly. The aim of this study was to evaluate the relationship serum levels of Zn and Cu with seizure occurrence in febrile children. In this case-control study, 270 children with 6 month to 6 years were ev...

OBJECTIVE To evaluate the impact of zinc supplementation on the clinical course, stool weight, duration of diarrhoea, changes in serum zinc, and body weight gain of children with acute diarrhoea. DESIGN Randomised double blind controlled trial. Children were assigned to receive zinc (20 mg elemental zinc per day) containing multivitamins or control group (zinc-free multivitamins) daily in thr...
