| Abstract | In this study, male Chinese loaches were exposed to 17ß-estradiol (E2), bisphenol A (BPA) and their mixtures, respectively, for 42 days using a semi-static exposure system. Plasma vitellogenin (Vtg) in male Chinese loaches was used as the determining endpoint. The results demonstrated that male Chinese loaches were sensitive to E2, and the vitellogenic responses showed time- and dose-dependent increase. Similarly, BPA induced the estrogenic effects in male Chinese loaches, and the vitellogenic response increased in a time- and dose-dependent manner. The synthesis of Vtg was initiated by the exposure to higher level of BPA (500µg/L) within 7 days, and a relative long-term exposure to lower concentrations of BPA (10-100µg/L) also led to the production of Vtg. The estrogenic effect of the binary mixture of E2 and BPA also showed a time- and dose-dependent response, which was more potent than that of individual compounds, and Vtg contents in the binary mixture group were higher than the summation of Vtg contents in the single-compound groups at the same concentration. |

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.
