This study shows clear evidence of an association between dyslexia and low concentrations of zinc in sweat. As in previous studies, higher concentrations of copper, lead, and cadmium and no differences in zinc concentrations were found in hair from dyslexic children compared with controls. In a study of adults one of us (SD) found that when sweat zinc concentration is very low hair zinc concent...

Zinc supplementation decreases the morbidity of lower respiratory tract infection in pediatric patients in the developing world. We sought to determine if zinc mediates a specific inhibitory effect against the major cause of pediatric lower respiratory tract disease, respiratory syncytial virus (RSV). We determined the in vitro inhibitory effect of three zinc salts (zinc acetate, lactate, and s...

objective: to determine the status of serum zinc in pregnant women in different gestational ages and correlation with socio-demographic and anthropometric factors in iranian women referring to prenatal care public health clinics . materials and methods: we analyzed the zinc concentrations in plasma samples obtained at different gestational ages from 961 women and recorded bmi at the first trime...

Zinc is an essential element important for growth, the nervous system, and especially the immune system. Zinc deficiency as well as levels well above normal, due to high-dose treatment, showed an impaired immune function. This review summarizes the current status of zinc's significance for leukocyte biology and health. In detail, the physiology of zinc and the impaired immune functions in zinc ...

BACKGROUND Zinc is an important trace element essential for numerous bodily functions. It is believed that a deficiency of zinc can lead to various conditions, including depression, on which this study is focused. It is still not known if hypozincemia leads to the development of depression or whether zinc deficiency is a result of depression. It is hypothesized that zinc may be a therapeutic ag...

Zinc is known to be essential for all highly proliferating cells in the human body, especially the immune system. A variety of in vivo and in vitro effects of zinc on immune cells mainly depend on the zinc concentration. All kinds of immune cells show decreased function after zinc depletion. In monocytes, all functions are impaired, whereas in natural killer cells, cytotoxicity is decreased, an...

Zinc concentration in erythrocytes is a suitable marker of peripheral tissue response to thyroid hormones. Therefore, the determination of erythrocyte zinc concentration has become an important marker for duration of preexisting hyperthyroidism in the clinical laboratory. We compared a new indirect erythrocyte zinc determination method with a commonly used direct method in 42 euthyroid and 14 h...

Three each of 3-year-old Angus and Simmental heifers, surgically modified to collect bile, were used to measure the effects of pregnancy and breed on bile flow, biliary copper and zinc excretion and plasma copper and zinc concentrations. Bile copper excretion was significantly higher at 7-mo of pregnancy when samples from both breeds were pooled. From then onwards it declined to its lowest, one...

Sickle cell anaemia (SCA) is associated with zinc deficiency; zinc supplementation may ameliorate some of its clinical manifestations including the relief of painful crisis. Subjects and Methods. Serum zinc levels were determined in 71 children with SCA and painful crisis and in equal numbers in steady state. Seventy-one children with AA genotype acted as controls. Qualitative assessment of zin...
