A cross-sectional survey of 2819 adults aged 20 years and above was undertaken in 2002 in Jiangsu Province. Zinc intake was assessed using a consecutive 3-day 24-h dietary recall method. Insufficient and excess intake was determined according to the Chinese Dietary Recommended Intakes. Four distinct dietary patterns were identified namely "traditional", "macho", "sweet tooth", and "healthy". In...

The aim of this study was to determine the relationship between seminal zinc concentration and spermatozoa-zona pellucida (ZP) binding and the ZP-induced acrosome reaction (ZPIAR) in subfertile men. Semen analyses and seminal zinc concentration assessments were carried out according to the World Health Organization manual for 458 subfertile men. A spermatozoa-ZP interaction test was carried out...

This factorial experiment with a randomized complete block design was performed in 4 replicates in order to examine the effect of foliar application of iron, zinc, and selenium on alfalfa’s yield under rainfed conditions in Aligoudarz, Iran. The experimental treatments included the iron at 3 levels: the control (non-use of iron), iron sulfate at the concentration of 3/1000, and complete liquid ...

Patients with liver disease may be at risk of zinc depletion. We measured polymorphonuclear cell, mononuclear cell, plasma, and erythrocyte zinc values, and erythrocyte carbonic anhydrase activity to assess zinc status in 17 patients with non-alcoholic liver disease (primary biliary cirrhosis and chronic active hepatitis) and 13 patients with alcoholic liver disease. The plasma zinc concentrati...

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...

Background: Thalassemia constitutes a major public health problem causing a significant burden on children and their families. Zinc deficiency plays an important role in many thalassemia-related complications like growth retardation, hypogonadism and delayed puberty which are frequently noted in adolescent age. Although zinc is supplemented to thalassemic patients visiting Day Care Center, Yang...

BACKGROUND Zinc is an essential micronutrient for human health and has numerous structural and biochemical roles. The search for a reliable, sensitive, and specific index of zinc status has been the subject of considerable research, which has resulted in the identification of a number of potentially useful biomarkers. OBJECTIVE The objective was to assess the usefulness of biomarkers of zinc ...

The concentration levels of salivary calcium, magnesium and zinc can vary in different localized oral, as well as systemic diseases and conditions. So far changes in the concentration levels of specific electrolytes in stimulated parotid saliva in HIV-positive/AIDS patients have been proven. The objective of this research was not only to study the concentration levels of calcium in non-stimulat...

The present study aimed at investigating the effects of copper and zinc in Vigna mungo (L.) growth and metabolism. Physiological parameters decrease consequently with increasing copper and zinc concentration in nutrient medium. Copper at 0.2mM concentration led to 32.12% and 47.82% reduction in fresh weight and dry weight respectively whereas, zinc at 1.50mM concentration resulted in 23.83% and...
