Abstract

|
|
Objectives: This study was performed to evaluate the effect of Samkieumgamibang (SKG) on osteoporosis.
Methods: The osteoclastogenesis and gene expression were determined in RANKL-stimulated RAW 264.7 cell. And, osteoblastogenesis was also determined in rat calvarial cell.
Results: SKG decreased the number of TRAP positive cell in osteoclast. It also decreased the expression of Cathepsin K, MMP-9, TRAP, c-fos, NAFTc1 and JNK1 in osteoclast. SKG increased the expression of iNOS in RANKL-stimulated in osteoclast. Otherwise, SKG inhibited TRAP activity in osteoclast. SKG increased cell proliferation, ALP activity, bone martix protein, collagen and nodule in osteoblast.
Conclusions: It is concluded that SKG might decrease the bone resorption resulted from decrease of osteoclast differentiation and it’s related gene expression. And, SKG might increase the bone formation resulted from increase of osteoblast function.
