| Abstract | Rabbits were immunized with an antigen of specific gravity, 1.15-1.21 isolated by density gradient sedimentation of the centrifuged medium of long-term monolayer cultures derived from spleens involved by Hodgkin's disease. The globulin fraction of the antiserum was absorbed to reduce reactivity with normal cellular antigens and tissue culture components, and was tested by the indirect fluorescent antibody technique with cells from 18 different Hodgkin's disease cultures, and 16 normal cultures derived from adult spleen and fetal spleen and thymus. With anti-Hodgkin's disease globulin diluted 1:40 and 1:80, positive surface staining was observed in 48% and 41%, respectively, of viable cells from Hodgkin's disease cultures, and in less than 5% of cells cells from normal cultures. Fluorescent staining of the cytoplasm without nuclear staining was observed in 51% of acetone-fixed cells from the Hodgkin's disease cultures and in 4-8% of cells from normal cultures. Reactivity of the antiserum with Hodgkin's disease target cells could be removed by absorption of the antibody with additional antigen of density 1.15-1.21 obtained from other Hodgkin's disease cultures. Antisera to fractionated medium from a normal spleen culture and to noncultured Hodgkin's disease tumor tissue were used as controls: 2-10% of viable and acetone-fixed target cells reacted and no difference was observed between Hodgkin's disease and normal cell cultures. In vitro propagation of tumor cells from patients with Hodgkin's disease is needed for detection of the Hodgkin's disease tissue culture antigen; the antigen could not be demonstrated in noncultured Hodgkin's disease tissue. |

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.
