| Abstract | OBJECTIVE: Diabetes mellitus has been known to be associated with a high risk of osteoporosis. Rubus coreanus Miquel, a traditional Asian herbal medicine, has various uses, such as antiobesity and antiosteoporosis treatment, among others. We investigated the effect of R. coreanus extracts on diabetic osteoporosis. METHODS: Rats were not treated, or treated with streptozotocin or R. coreanus, or ovariectomized, in various combinations. After 6 weeks of treatment, the rats were killed, and serum biochemistry, histopathology, immunohistochemistry, and semiquantitative reverse transcription polymerase chain reaction were performed. In addition, in vitro studies were performed in MC3T3-E1 and RAW 264.7 cells. RESULTS: Rats treated using R. coreanus showed significant improvement in trabecular bone histopathology. Increased expression of osteocalcin was observed in rats treated with streptozotocin and R. coreanus, whether ovariectomized or not. In addition, the expression levels of cannabinoid receptors 1 and 2 and receptor activator for nuclear factor κß ligand were increased in rats that were ovariectomized and treated with streptozotocin and R. coreanus but decreased in those treated with streptozotocin and R. coreanus alone. These results indicate that the antiosteoporotic effect of R. coreanus in postmenopausal diabetic osteoporosis is attributable to the cannabinoid receptor-dependent maximal up-regulation of osteoblastogenesis. CONCLUSIONS: The present study shows that R. coreanus may rescue diabetic osteoporotic bone loss by simultaneous alteration of activation in osteoblasts and osteoclasts. Furthermore, these effects may be partially influenced by the up-regulation of the endocannabinoid system. In conclusion, dietary R. coreanus may be of use in improving the conditions of diabetic osteoporosis. |

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.
