| Abstract | The separation of haemocytes from the mussel Mytilus edulis was carried out on continuous Percoll gradients. The haemocytes separated into three distinct layers, the first comprised 97% basophilic cells, the third comprised 84% eosinophilic cells and the middle layer was a mixture of eosinophilic and basophilic cells. Enzyme cytochemistry demonstrated arylsulphatase, phenol oxidase and peroxidase associated with the haemocytes from the third layer. Lectin-binding studies showed differential binding of lectins to the separated cells. The ultrastructural morphology demonstrated that the first layer of cells was composed predominantly of small agranular cells with a high nucleus to cytoplasm ratio. The second layer comprised a mixture of cells with the majority being granular cells with small granules. The third layer was almost exclusively composed of granular cells with small and large granules. Assays to assess the function of the different cells demonstrated that respiratory burst activity, measured as the reduction of cytochrome-c, was carried out almost entirely by the eosinophilic haemocytes. Similarly, levels of phagocytosis, measured as uptake of Escherichia coli, were much higher in the eosinophilic haemocytes. Of the potential mitogenic factors investigated, concanavalin A and pokeweed mitogen showed some evidence of inducing haemocyte proliferation. |

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.
