| Abstract | Several trace elements, particularly, manganese (Mn) and zinc (Zn), are essential in bone metabolism as cofactors for specific enzymes. It has been reported that there exists the relationship between osteoporosis and trace element-deficiency and the efficacy of Ca, Mn and Zn supplementation on spinal bone mineral density in postmenopausal women. Traditional Chinese medicines (TCM), such as Herba epimedii, were proved to be effective for prevention of osteoprosis in vivo; however, the efficacy of the main constituents and/or crude extract was not ideal in vitro, which suggested that they may work in another way. The purpose of the present study was to examine whether the combination of icariin and total flavonoids (TF) from Herba epimedii with mineral elements, which were abundant in Herba epimedii, would have a more beneficial effect on the viability and differentiation of primary osteoblasts than either agent alone, and to analyze the dada for a possible synergistic, additive or antagonistic effect. The combinations of 10 μmol/L Zn, Ca and Mn with icariin and total flavonoids greatly improved the cell viability and meanwhile dramatically enhanced the alkaline phosphatase activity as compared to each agent alone. On the other hand, an increased cell growth inhibition was also observed by combining 0.1 μmol/L, 1 μmol/L Zn with 10 μmol/L icariin, and 10 μmol/L Mn with 0.06 μg/mL total flavonoids. Meanwhile a decreased alkaline phosphatase activity was also found in several icariin-Zn/Mn and total flavonoids-Zn/Ca/Mn combinations. These results suggested that mineral elements (Zn, Ca, Mn) greatly enhanced the efficacy of icariin and total flavonoids from Herba epimedii on the viability and differentiation of primary osteoblasts by certain combinations. |

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.
