Bone is a dynamic tissue which is constantly remodelled by subsequent cycles of
bone resorption and formation. Glucocorticoid and vitamine D3 are known
as regulating substances in bone metabolism. In vitro experiments using bone tissue, it
was suggested that glucoccorticoid inhibits bone resorption, whereas the effect of
glucocorticoid on bone formation are complex- increasing or decreasing effect. The
active form of vitamin D3, 1,25-dihydroxycholecalciferol
¡²1.25-(OH)2D3¡³, has been reported to stimulate osteoblastic
activities including the production of ALP, type ¥°collagen, and osteoclacin.
The purpose of this study was to evaluate the effect of admixture of vitamin
D3 and dexamethasone, one of glucocorticoids, on osteblastic cell
line(MC3T#-E1). Alkaline phosphatase(ALP) and MTT assay were conducted in the
cultivated cells with 1, 10, 100§¬/§¢ of 1,25-(OH)2D3 and/or
10nM/§¢, 100nM/§¢, 1¥ìM/§¢ of dexamethasone.
The observed results were as follows.
1. The activity of osteoblastic cells with 1¥ìM/§¢ of dexamethasone was significantly
increased at 1-day cultivation with comparison to control group, but was decreased
afterwards. But the activity of ALP was greatest in 1¥ìM/§¢ of dexamethasone and
increased with time lapsed.
2. The activity of osteoblastic cells with vitamin D3 was significantly
increased dose-dependently at 1-day cultivation, but was significantly decreased in
10nM/§¢ or 100nM/§¢ at 2-day or 3-day cultivation, and was greatest in 100nM/§¢ at
3-day cultivation.
3. In case of admixture of dexamethasone and vitamin D3 at 2-day
cultivation, but was increased again at 3-day cultivation, which was greater than that in
control or dexamethasone only group. The activity of ALP was decreased at 1-day
cultivation, but was increased in the admixture of 10nM/§¢ or 100nM/§¢ of
dexamethasone with 100nM/§¢ of vitamin D3 at 2-day cultivation, and was
again decreased at 3-day cultivation.
