To develop osteoclast culture kid suitable for
evaluation of the curing medicines of osteoporosis and arthritis, the
apatite/collagen composite films with excellent bioabsorption characteristics
were prepared using cattle bone-originated apatite and pig-originated
collagen by the wet methods. On the composite films, osteoclast was
cultivated as one of substituted materials of natural dentin. The amounts of
bone substrates that the osteoclast decomposed and absorbed were measured
from the fluorescence intensity in the culture solutions. The quantitative
method for making the rapid determination of bone destruction quantity after
the medicine-additives was discussed. |
