| Abstract | ETHNOPHARMACOLOGICAL RELEVANCE: Panax quinquefolius L. has been used as a proverbial tonic in oriental countries for hundreds of years. It is used as a traditional medicinal herb to nourish vitality. AIM OF THE STUDY: The purpose of our study was to inquiry the activation effects on murine peritoneal macrophages of a novel protein separated from the roots of Panax quinquefolius L. MATERIALS AND METHODS: In our work, a novel protein of the roots of American ginseng (AGNP) was separated and purified from the roots of Panax quinquefolius L. The characteristic was investigated with SDS-PAGE, high pressure gel filtration chromatography (HPGFC) and matrix-assisted laser desorption ionization/time-of-flight mass (MALDI-TOF-MS) spectrometry method. The method of neutral red was carried out to investigate the phagocytosis of peritoneal macrophages. And Griess method and colorimetry were executed to detect the level of nitric oxide and iNOS activity respectively. Tumor necrosis factor- and interleukin-6 were analyzed by enzyme linked immunosorbent assay (ELISA). RESULTS: Our results demonstrated that the subunit molecular weight of AGNP determined by SDS-PAGE was 15kD and the content of proteins determined by Bradford assay was 2.31mg/mL. The molecular weight of the AGNP was15, 114Da both of electrophoresis and MS purity. And the result of HPGFC showed that the molecular weight of AGNP was 31,086Da, Immunological studied indicated that AGNP could conspicuously increase phagocytosis of macrophages, facilitate the nitric oxide production, Tumor necrosis factor- and interleukin-6 production. What is more, AGNP dose-dependently stimulated NO formation through the up-regulation of iNOS activity. CONCLUSIONS: In conclusion, AGNP had good immunoregulatory effects supporting the traditional claims and may provide a valuable therapeutic strategy to promoting immune function and metabolism. |

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.
