We investigated the effects of trace element deficiency on drug-metabolizing enzymes in rats. Weanling rats were fed a selenium-deficient diet (Torula yeast) or a normal diet (0.5μg selenium) until 20 weeks. After six weeks of the selenium-deficient diet, an increase in aniline hydroxylase activity was observed in the selenium-deficient rats, but the activity of aminopyrine N-demethylase was re...

Zinc deficiency is not only the cause of low productivity of crops, but it also results in low zinc content in seeds, which leads to poor dietary zinc intake. To study the effect of zinc foliar application on improving plant yield and seed zinc content for human consumption, chickpea plants were raised in refined sand culture with deficient (0.2 μM) and sufficient (1μM) supply of zinc under gla...

Since similar symptoms and findings can be seen in the deficiencies of both iron and zinc, we aimed to evaluate the serum zinc levels of women with iron deficiency anemia(IDA). This study was conducted on women with iron deficiency and healthy control group. When serum zinc levels compared, it was found to be lower in the IDA group which was statistically significant. With the help of these stu...

Zinc (Zn) deficiency is a common aliment predicted to affect 17% of the world's population. Zinc is a vital micronutrient used for over 300 enzymatic reactions and multiple biochemical and structural processes in the body. Although whole blood, plasma, and urine zinc decrease in severe zinc deficiency, accurate assessment of zinc status, especially in mild to moderate deficiency, is difficult a...

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: a growing body of investigations demonstrated the essence role of zinc on growing and maintaining bone tis sue .the idea that zinc could enhance bone content and adjourn or prevent osteoporosis in men, has been experimented as a hy pothesis. methods: six hundred healthy men (age 20-69 yr) through iranian multicenter osteoporosis study (imos) which is a na tional project running in 5...

Adequate zinc stores in the body are extremely important during periods of accelerated growth. However, zinc deficiency is common in developing countries and low maternal circulating zinc concentrations have previously been associated with pregnancy complications. We reviewed current literature assessing circulating zinc and dietary zinc intake during pregnancy and the associations with preecla...

Abstract Background: Convulsion in neonatal period is a considerable clinical issue because of its potential brain damage.One of the benign neonatal seizures known as the  fifth day fits ,is due to zinc deficiency. Zinc is a rare element which has spread throughout the body fluids and tissues especially central nervous system. Reduction of neurons’ stimulation has been ascribed as the main eff...

OBJECTIVE To present an overview of micronutrient status of Mexican children in 2006. MATERIALS AND METHODS Data on iron, zinc, folate and vitamin B12 deficiencies and low serum copper and magnesium were gathered and critically analyzed from the 2006 National Health and Nutrition Survey. RESULTS Iron deficiency is still the main nutritional deficiency in children (13%-26%). Zinc deficiency ...

In atherosclerosis and diabetes mellitus, the concomitant presence of low-grade systemic inflammation and mild zinc deficiency highlights a role for zinc nutrition in the management of chronic disease. This review aims to evaluate the literature that reports on the interactions of zinc and cytokines. In humans, inflammatory cytokines have been shown both to up- and down-regulate the expression ...
