| Abstract | The dominant lethal assay was utilized to assess the reproductive performance in male mice, possible genetic hazards, and persistent damage of aluminum (Al). Al chloride, AlCl(3), was administered subcutaneously to CD-1 adult male mice at dosages of 0, 7, or 13mg Al/kg body weight/day for 2 weeks of pre-mating periods. Females were not dosed at any time during this study. At the end of the exposure period, each male was caged with three virgin females each day. The mean mating frequencies of the Al-treated groups reduced consistently from week 4 to 6, and a dramatic reduction in male fertility was also observed. However, the mating frequency restored to near normal control levels as the experiment terminated. Results showed significantly higher numbers of post-implantation losses, foetal mortality, and induced petechial haemorrhage; also significant decreases in body weights of viable foetus throughout weeks 3-8 in the Al-treated groups. The weights of the reproductive organs of the Al-dosed animals decreased significantly as Al accumulation increased in the testes. The spermatogenetic impairment within the seminiferous tubules was also apparent. Nevertheless, these disturbances disappeared at the end of the experiments. In summary, the results demonstrated that Al exerted substantial hazards on male reproductive function and produced genetic toxicity. However, these effects were found to be reversible. |

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.
