| Abstract | Antitumor effects of a ginsenoside Rg(3)-fortified red ginseng preparation (Rg(3)-RGP) were investigated in human non-small cell lung carcinoma (H460) cells using in vitro cytotoxicity assay and in vivo nude mouse xenograft model. Immunomodulatory effects of the preparation were also assessed by measuring the facilitating activities on the nitric oxide (NO) release from peritoneal macrophages, in vitro and in vivo lymphocyte proliferation, and the carbon clearance from circulating blood. In a cell level, Rg(3)-RGP exerted H460 cytotoxicity and facilitated splenocyte proliferation at very high concentrations, without affecting NO production. However, oral administration of Rg(3)-RGP (100-300 mg/kg) enhanced carbon particle-phagocytic index of blood macrophages up to 360-397% of control value. In addition, Rg(3)-RGP significantly increased the splenocyte proliferation (23% at 100mg/kg). In tumor-bearing mice, 28-day oral treatment with Rg(3)-RGP (100mg/kg) remarkably suppressed the tumor growth, leading to the decrease of the tumor volume and weight by 30-31%, which was comparable to the effect (27-29% reduction) of doxorubicin (2mg/kg at 3-day intervals). While Rg(3)-RGP did not cause adverse effects, intravenous injection of doxorubicin markedly decreased body and testes weights, and exhibited severe depletion of spermatogenic cells in the atrophic seminiferous tubules. These results indicate that Rg(3)-RGP exerts antitumor activities via indirect immunomodulatory actions, without causing adverse effects as seen in doxorubicin. |

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.
