| Abstract | Many employed chemicals in industries have estrogenic hormone effects on organisms, and these are called as environmental estrogens. Environmental estrogens have adverse effects on development and function of reproductive organs of the birds. Bisphenol A (BPA) is one of the best known environmental estrogens widely found in plastic products. In this study, we injected BPA and the synthetic estrogen diethylstilbestrol (DES) in ovo and then examined and compared the effects of those on the uteri (shell gland) of the adult hens by histological methods. Five groups have been designed in the current study. Only vehicle substance was given in ovo to the control group and BPA (67 or 134 μg/g egg) and DES (0.02 or 0.2 μg/g egg) were administered in the experimental groups. Tissue specimens were taken from uteri of hens at 21 weeks of age, prior to the laying period. Estrogen receptor alpha (ERα) was immunohistochemically stained. It was observed that the hatching proportion in BPA (67 μg and 134 μg/g) was lesser than the other groups (P < 0.01). Uterine tubular glandular density and thickness of tunica mucosa were found to have reduced (P < 0.01) in BPA (134 μg/g) and DES (0.2 μg/g) groups, in comparison with those of the control and the other experimental groups. Uterine gland epithelium revealed positive immunoreaction for ERα. These findings suggested that administration of BPA and DES at high doses affected embryonic development in a negative way, and this adverse effect was seen less in adult period. |

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.
