Description
本発明の次の目的は、できる簡単な方法で人体に消化吸収され易い魚鱗由来のハイドロキシアパタイトと魚鱗由来のコラーゲン生体適合性材料の製造方法を提供せんとするにある。
Ca 5 (PO 4 ) 3 OH=5×40.078+3×(30.973762+4×15.9994)+15.9994+1.00794
=502.311426
Caからの換算係数
Ca 5 (PO 4 ) 3 OH/(5×Ca)=502.311426/(5×40.078)
=2.506669125 →2.5067
70.2g÷2.5067≒28.0g
これらの測定はすべて和光純薬工業製の臨床生化学検査薬キットを使用した。
1.複合体は骨密度上昇と骨内部構造改善効果の両者を示すが、むしろ骨密度上昇が主な効果として認められた。そして、骨幹部の皮質骨密度の上昇を示したのは、複合体だけであった。
2.MK−7は骨密度上昇と骨内部構造改善効果の両者を示すが、むしろ骨内部構造改善が主な効果として認められた。
3.MK−4は骨内部構造改善が主な効果として認められた。
