| Abstract | Aflatoxin B1 (AFB1) has been consistently shown to be a potent mutagen and carcinogen in humans and animals. On the other hand, resveratrol (RSV), a polyphenol, has several positive biological actions such as protection of cells against DNA damage. In the present study, the antigenotoxic effect of RSV was studied against a genotoxic dose of AFB1 using the damage parameters of chromosomal aberrations (CAs) and sister chromatid exchanges (SCEs) in cultured human lymphocytes. Whole blood samples from three healthy male donors were used for this experiment and the effects of various concentrations of RSV (0, 10, 15, 25, 40, 75 and 100 µM) and AFB1 (10 µM) were tested. The results revealed that the frequencies of SCEs and CAs in lymphocytes were significantly (p < 0.05) increased by AFB1 as compared to controls. The results also showed that RSV was not genotoxic. Moreover, the number of SCEs and micronuclei induced by AFB1 could be significantly minimized by the presence of RSV. Our results suggest for the first time that RSV can antagonize the ability of AFB1 to cause DNA damage that leads to the formation of SCEs and CAs. |

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.
