Abstract
The objective of this study was to investigate the inhibitory effect of taurine and alendronate on the osteoclast differentiation. Osteoblasts and bone marrow cells from 1-2 day old mouse were co-cultured in 10% fetal bovine serum - minimal essential media (FBS-MEM). Osteoclast differentiation was induced by adding the sonicated extracts of Porphyromonas gingivalis (P.gingivalis). Osteoclasts were identified using tartrate resistant acid phosphotase staining (TRAP). Alendronate of 10^{-7}, 10^{-6}, 10^{-5}M and taurine of 500, 1000, 1500㎍/ml were added respectively. The cytotoxic effects of alendronate and taurine were examined using MTT(3-(4,5-dimethylthiazol -2-yl-2,5-diphenyltetrazo- lium bromide) method. After culturing with the sonicated extracts of P.gingivalis, the amounts of IL-6 in the culture supernatant were measured and compared using the ELISA method. The results were as follows : 1. Osteoclasts were differentiated at the concentration of 0.01~0.1㎍/ml sonicated extracts of P.gingivalis. (P<0.05). 2. Alendronate inhibited osteoclasts differentiation at the concentration of 10-5 M when the concentration of sonicated extracts of P.gingivalis was 0.01㎍/ml. 3. Taurine inhibited osteoclasts differentiation at the concentration of 1500㎍/ml when the concentration of sonicated extracts of P.gingivalis 0.01㎍/ml. 4. In cytotoxic test (MTT test), no cytotoxic effect was evident in all concentrations of alendronate and taurine. 5. Taurine (10-5M) and alendronate(1500㎍/ml) did not change the amounts of IL-6 induced by sonicated extracts of P.gingivalis significantly.
