| Abstract | Scanning electron microscopy of the epithelial cells of the female hamster harderian gland reveals a range of surface features. Some cells exhibit a uniform covering of microvilli while others, often with swollen apices, are relatively devoid of microvilli. Surface pitting is frequent for all cells; pits represent regions of exocytotic lipid vacuole release. A similar range of surface appearances occurs in the male gland but here cells with uniform microvilli represent type I cells (characterised by small lipid vacuoles) while swollen cells with sparse microvilli are type II cells (characterised by large lipid vacuoles). It is suggested that different cell forms represent a single cell type in varying activity states. Luminal debris is often marked, consisting chiefly of lipids. Solid porphyrin accretions, sometimes surrounded by neutrophils, are numerous in female (but not male) glands. Interstitial mast cells are also numerous in the female gland. The gland contains fenestrated capillaries and extensive lymphatics. The duct of the gland, which has received little attention, possesses ciliated cells, nonciliated cells and basal cells. Ciliated cells possess kinocilia and relatively tall thin microvilli, as well as some lipid vacuoles. Nonciliated cells bear shorter microvilli, apically located mucoid granules, and lamellar formations of smooth endoplasmic reticulum. The basal cells are squat and pyramidal; their lateral walls, which interdigitate with the main duct cell types, show pronounced folding. |

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.
