そこで本発明は、従来よりも生体親和性が高いハイドロキシアパタイトを提供することを目的とするものである。
[1]Mgを含有するハイドロキシアパタイト、
[2]微小結晶のハイドロキシアパタイトを含む、[1]のハイドロキシアパタイト、
[3]化学式(Ca:Mg)10(PO4)6(OH)2
(上式において、(Ca:Mg)10はCaとMgとの合計元素数が10であることを意味し、Caは9~7、Mgは1~3である。)
で表される、[1]又は[2]のハイドロキシアパタイト、
[4]生物由来の材料からなる、[1]~[3]のいずれかのハイドロキシアパタイト、
[5]さらに、Na、K及びSiから選ばれる少なくとも一種のミネラルを含む、[1]~[4]のいずれかのハイドロキシアパタイト、
である。
本発明のハイドロキシアパタイトは、Mg(マグネシウム)を含む。Mgは、生体骨に含まれているミネラルの一種であり、生体骨においてMgは、骨芽細胞や破骨細胞を活性化し、骨細胞を促進させる作用を有している。このような作用を有するMgを含んでいる本発明のハイドロキシアパタイトは、従来のハイドロキシアパタイトに比べて、食品添加物、化粧品原料、医薬品原料、人工骨などの生体材料の用途において、より高い生体親和性を有しているのである。
具体的にX線構造解析において、2θが31.500~32.500°に現れるピークにおける結晶子サイズが10~200Åであるハイドロキシアパタイトは、微小な結晶化したハイドロキシアパタイトのみのものであること、又は微小な結晶したハイドロキシアパタイトと結晶化の程度が低い、低結晶型ハイドロキシアパタイトとが混合されたものであるといえる。
なお、結晶子サイズとは、結晶粒の大きさを表し、結晶性を表す目安となる数値である。結晶子サイズの数値が大きいほど、測定対象である物質の結晶性が高いことを意味する。逆に言えば、結晶子サイズの数値が小さいほど、ハイドロキシアパタイトは低結晶又は微小な結晶化したものであることを意味する。結晶子サイズは、例えば、株式会社リガク社製のX線解析装置である、型番:RINT2200V/PCにより測定できる。
好ましくは、2θが31.500~32.500°に現れるピークの結晶子サイズが30~150Å、より好ましくは50~120Åである。

(上式において、(Ca:Mg)10はCaとMgとの合計元素数が10であることを意味し、Caは9~7、Mgは1~3である。)
で表されるものであることが好ましい。つまり、ハイドロキシアパタイトを構成するCaの一部がMgと置換された構造のものであることが好ましい。
また、生物由来の材料からなることにより、カルシウム補給剤として用途のような、経口して服用する用途や食用としても人体に安全なハイドロキシアパタイトとすることができる。
CaOの原料として卵殻を1000℃で20時間焼成したものを用いて製造したハイドロキシアパタイトとCaOの原料としてサンゴを1000℃で20時間焼成したものを用いて製造したハイドロキシアパタイトを用意した。また、比較のために市販のハイドロキシアパタイト(試薬)を用意した。これらのハイドロキシアパタイトをICP発光分析装置(島津製作所(株)製 ICPS-8100)を用いて微量元素の分析を行った。分析に当たって、試薬には和光純薬社製の標準液 Mg、Na、Kのそれぞれ1000ppmのものを用いた。また、各試料は1.00gを50mLメスフラスコにとり、少量の塩酸で溶かしたのち、50mLにメスアップしたものを測定した。
分析結果を表1に示す。なお、表1中の数値は、質量ppm(mg/kg)を示している。
卵殻由来のハイドロキシアパタイトについて、疑似体液(SBF)を用いた生体活性評価を行った。この評価は、試料を疑似体液(SBF)中に浸漬し、一定時間後試料表面へのハイドロキシアパタイト生成量を測定したものである。ここに、疑似体液は、ヒトの体液とほぼ等しい無機イオン濃度を有するものであり、以下の成分により調製された。
その後、各試料の質量を測定して、ハイドロキシアパタイトの質量増加量を計算した。
ハイドロキシアパタイトAの測定結果を表2に示す。
