| Abstract | BACKGROUND: Lead exposure is a global environmental problem that induces lifelong adverse health effects. Our aim was to investigate the effect of dietary supplements and natural antioxidants on blood lead levels (BLL) in lead-exposed mice, and observe their impact on the absorption of calcium, iron and zinc in vivo. RESULTS: All of selected dietary supplements (calcium lactate, zinc sulfate, ferrous sulfate, ascorbic acid and calcium-rich milk) and natural antioxidants (extract of Chinese wolfberry, extract of Hangzhou white chrysanthemum and antioxidant extract of bamboo leaves) have promising capacity of reducing BLL in lead-exposed mice with an reduction range from 56.2% to 65.1%. The metal ion-mediated chelating and competitively inhibitory mechanisms may elucidate their reduction effect. Besides, blood calcium, iron and zinc levels were not significantly changed in all of the experimental groups, indicating that the intake of all additives does not disturb the absorption of essential mineral elements in mice. CONCLUSION: All the studied additives not only effectively reduce BLL, but also maintain normal calcium, iron and zinc absorption in mice. The formulation of calcium, iron and zinc supplements and/or polyphenol and vitamin-rich antioxidants may constitute an important secondary prevention effort to reduce BLL and lead exposure. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
