Description
亜鉛含有水酸アパタイト多孔質微粒子の作製例と、その表面をポリ乳酸薄膜により被覆した例を示す。
<実施例2>
摘出した組織のCa量の測定結果およびその病理組織図について例示する。
<実施例3>
実施例1のZn0.5HAp微粒子にエリスロポエチンを担持させる方法を比較例とともに以下に例示する。
<実施例4>
実施例1で作製したZn0.5HAp微粒子を400℃で焼成して、エリスロポエチンを担持させる方法を例示する。すなわち、400℃で焼成した試料を用いて、5000IUのエリスロポエチンを溶解させた10%PBS溶液中(10ml)に加え、10分間吸着させた後、遠心分離(3000G・10分間)した。2mlの塩化亜鉛溶液(10mg/ml、pH5.5)を加えて3分間分散させた。その後、遠心分離(3000G・10分間)を行い、精製水にて洗浄後、エタノール(10ml)を加えて遠心分離を行い、乾燥させた。30mgのポリ乳酸(分子量85000〜160000)を1mlの塩化メチレン溶液に溶解させ、さらにエリスロポエチン担持Zn0.5HAp/PLA複合微粒子100mgを分散させ、エバポレータにて粒子を栓塞して乾燥させた。これを試料4とした。
<実施例5>
実施例2および3で作製した試料(1〜4)100mgを5mLの生理食塩水に分散させ、ICR雄マウスに一匹当たり0.5mL皮下投与(500IU/body)した。投与後大静脈より全採決を行い、1,3,8,14日後に血液学的検査およびエリスロポエチン定量を行った血液学的検査は、ヘモグロビン(HGB)、赤血球数(RBC)、ヘマトクリット(HCT)の測定を行った。その結果、試料3および4については極めて優れた徐放効果が得られルことが確認された。
また、試料1および2のPLA被覆しない場合においても、亜鉛を全く担持、含有させない場合に比べて徐放効果が良好であることも確認された。
Claims (8)
