| Abstract | Naphthalene, a bicyclic aromatic hydrocarbon, has toxic effects on animals and humans. Although recent studies stressed on the genotoxic and cytotoxic effects of naphthalene and its metabolites on eukaryotic cells, there is a big controversy among the results of these studies. The aim of this study is to investigate the effects of naphthalene and its metabolites on the cytotoxicity and genotoxicity in the human lymphocytes in the culture. The genotoxic and cytotoxic effects of naphthalene and its metabolites, 1-naphthol and 2-naphthol, were studied using cytotoxicity test (lactate dehydrogenase and cell proliferation (WST-1) assays) and DNA fragmentation assay (terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay). Naphthalene and its metabolites had no significant cytotoxic effect on treated samples when compared with untreated ones. This result was also confirmed by WST-1 assay. In the TUNEL assay, DNA fragmentation was induced significantly by all concentrations of naphthalene and 2-naphthol and 50 and 100 µM concentrations of 1-naphthol (p < 0.05 or 0.001). In the DNA fragmentation, the most effective dose of 2-naphthol (63%) was 100 µM, when compared with negative control group (13%). These results suggest that naphthalene and its metabolites, 1-naphthol and 2-naphthol, may cause DNA damage on human lymphocytes. |

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.
