Effectiveness of zinc in modulating perinatal effects of arsenic on the teratological effects in mice offspring
Exposure to arsenic via drinking water is considered as a worldwide problem. Studies have shown that arsenic exposure during pregnancy affects embryogenesis and offspring development in rats and mice. Zinc as a micronutrient regulates many physiological functions, including an antioxidative role und...
