1. 65Zn was injected intravenously during transjugular liver biopsy and, from simultaneous hepatic and peripheral venous blood samples, hepatointestinal 65Zn extraction was calculated. Hepatic zinc content was measured in biopsy specimens. 2. On the same occasion samples of liver tissue were taken and their zinc content was measured by atomic absorption spectrophotometry. 3. Seven patients with...

conclusions our study showed minority of cases had zinc deficiency, which is different from previous reported results, because the most subjects in this study had normal level of zinc. we recommend further studies on diet in our population. it seems the only reason for the obtained result in this part of iran with low socioeconomic status may be related to the diets containing high levels of zi...

background: recurrent herpes labialis (rhl) is one of most common infective vesiculoulcerative lesions. according to some studies administration of topical and/or systemic zinc compositions has been effective in treatment and prevention. this article aims to comparison of zinc level in healthy subjects and rhl patients in acute and convalescent phases. materials and methods: this was a retrospe...

A method for determination of zinc contents in very small samples of hair was developed in order to estimate the zinc concentration in the human body. All steps from weighing of samples to ashing and preparation of the test solution were done in a tube designed by us to prevent contamination and to improve handling. Zinc concentration was determined with flame atomic absorption spectrophotometr...

Plasma concentrations of some micronutrients are altered in the setting of acute infectious or inflammatory stress. Previous studies have provided conflicting evidence concerning the extent and direction of changes in plasma zinc concentrations during the acute phase response. We carried out an observational cohort study in 689 children enrolled in a randomized trial of zinc supplementation dur...

11-409 12015 Zinc, as a cofactor for numerous enzymes in the body, plays an important role in growth and development, wound healing, taste acuity and appetite, immune function, and gene expression (1-4). Although zinc is needed in only small amounts by the human body, some people are vulnerable to mild to moderate zinc deficiency (1). Zinc deficiency results not only from a diet low in zinc-ric...

Employing the oxidative coupling of phenylacetylene with benzaldehyde as a model reaction, a density functional theory (DFT) study combined with extended X-ray absorption fine structure (EXAFS) experiment was carried out to reveal the difference between dinuclear and mononuclear zinc mediated nucleophilic addition. Newly reported DFT method M11-L computed results suggest that the mononuclear zi...
