| Abstract | AKR/J mice, 80-90% of which ordinarily die of spontaneous lymphocytic leukemias by 12 months of age, were significantly protected from developing leukemia in the initial experiment by a single course of treatment with AKR serotype-specific antibodies mad in goats and processed as immune gamma globulin (IgG). In experiment 1, IgG was given on the day of birth and on four additional days, and finished on day 14. This schedule resulted in suppression of over 4 logarithms of normal virogene expressions up to 25 days of age and led to partial viral suppression for over 200 days of age. At 365 days of age, 20 of 24 (83.3%) control animals were dead of leukemia whereas six of 30 (20%) treated animals had died of leukemia. In a second experiment, only four inoculations of IgG were given from birth to 20 days, after which they were given three inoculations of radiation-killed vaccine specific for AKR-Gross leukemia virus and one injection of murine sarcoma virus-Gross leukemia virus 10 days later. This combined immunization procedure provided significant virus suppression up to 288 days of age. At 300 days of age, 30 of the 50 (60%) controls had died of leukemia while only 1 of 24 (4.2%) of the immunized mice developed fatal leukemia; the significance of protection for each of the experiments was P LESS THAN 0.001. We conclude that these data establish in classical fashion with type-specific immunosuppression the determining role of type-C endogenous virogenes in leukemogenesis and, at the same time, also established the feasibility of nearly total prevention of leukemia in AKR mice. |

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.
