| Abstract | The effect of acyclovir [9-(2-hydroxyethoxymethyl)guanine] on Epstein-Barr virus (EBV) DNA replication in the lymphoblastoid cell lines P3HR-1 and Raji is reported. Acyclovir at a concentration of 100 microM completely inhibited EBV DNA synthesis in superinfected Raji cells, but did not inhibit DNA synthesis in mock-infected cells. The number of EBV genome equivalents per cell in the virus-producing cell line P3HR-1 was significantly reduced by acyclovir, whereas the number of latent EBV genomes in Raji cells was not affected by the drug. In situ cytohybridization performed on untreated P3HR-1 cultures revealed the presence of relatively large amounts of EBV DNA in 15 to 20% of the cells. After a 100 microM drug treatment, no P3HR-1 cells contained levels of EBV DNA detectable by in situ cytohybridization. Indirect immunofluorescence studies demonstrated that during treatment with 100 microM acyclovir for 7 days, the percentage of P3HR-1 cells expressing viral capsid antigen was reduced. The EBV DNA remaining in P3HR-1 cells after treatment with 100 microM acyclovir (approximately 14 genomes per cell) had the properties of covalently closed circular DNA with an average molecular weight of 108 X 10(6), as determined by contour length measurements. |

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.
