本発明は、唾液および他の胃分泌物がかなりの量のリンを含むという発見に基づく。特に、唾液は、リンの主要な供給源(該リンは次いで、身体中で再循環される)であると考えられる。
本発明の目的のために、経口組成物は、被験者に経口経路によって投与することができるいずれかの組成物であると企図する。
徐放性水酸化マグネシウム:250mg、
徐放性水酸化アルミニウム:250mg、
スクロース粉末、デンプン、ソルビトール、マンニトール、芳香剤、サッカリンナトリウム、ステアリン酸マグネシウム。
唾液中のリンの測定
a)透析処置を受けている尿毒症の患者
週に3回、ポリスルホン透析器を用いて定期的に重曹透析(HD)を受けている68尿毒症患者(47男性および21女性、年齢61.6±9.4)、および同年齢の30コントロールの健康被験者を含んだ。
−血中Ca 8.73 mg/dl(幾何学的平均値)−95% CI、8.49〜8.98;
−唾液中Ca 7.21 mg/dl(幾何学的平均値)−95% CI、6.58〜7.91;
−血中P 5.73±1.31 mg/dl(平均値)−95% CI、5.41〜6.04;
−唾液中P 30.27 mg/dl(幾何学的平均値)−95% CI、26.50〜34.58;
−PTH 5.73±143.63 pg/ml(平均値)−95% CI、110.57〜167.69;
−唾液中P 30.27 mg/ml(幾何平均値)−95% CI、26.50〜34.58。
−唾液中P 12.66±5.25 mg/dl(平均値)−95% CI、10.58〜14.73。
保存療法下での110患者(59男性および51女性、年齢65;17〜90)は、メッシーナ(Messina, イタリア国)におけるパラルド病院(Papardo Hospital)での透析ユニットでランダムに選別した。リンアッセイを妨害することが知られる薬物を用いた処置下にある患者を排除するように、注意を払った。治験プロトコールは、血中クレアチニンアッセイおよび血中リンアッセイ、並びに唾液中リンアッセイを含んだ。終夜の絶食後に、血液(4ml)および唾液(2ml)の試料を午前8時に採取した。糸球体濾過率(GFR)を、下記のMDRD式に従って算出した。
[GFR (ml/分/1.73 m2) = 186×(血中クレアチニン)-1.154×(年齢)−0.203×(女性の場合は、0.742)]

キトサン製剤
リン酸塩の量を分離した中および低−粘性のキトサンを、1次元スペクトル取得を有する500MHzの高分解能31P−NMR(HR−NMR)によって300°Kで測定した。
a)低−と中−粘性のキトサン(フルカ社製, カタログ番号50494およびカタログ番号28191)および、PBS(リン酸塩緩衝化生理食塩水−シグマ社製)を有する異なる濃度の溶液との相互作用を研究し、そして同じ実験条件下での純粋なPBSおよびキトサン含有PBSの間でのリン酸塩の量の差違を比較し;
b)文献(チャング(Yong Zhang)およびチャング(M. Zhang)による, J. Biomed. Mater. Res., 2002, Dec. 5, 5, 62(3): 378-86)に従って、PBSと異なる濃度の中粘性キトサン溶液との相互作用を研究した。
低−および中−粘性のキトサンの0.2、1.0、および1.5gを、PBS(10ml)に加えて、2、10、および15%p/vのキトサン溶液を得た。
中−粘性キトサンのそれぞれ1.0および2.0gを0.2M 酢酸(10ml)中に溶解して、10および20%p/vのキトサン溶液を得た。その後に、該得た溶液を50℃で約2時間撹拌して、均一な高分子溶液を得た。該溶液をろ過して空気泡を除いた。該ろ過溶液にPBS(0.0931g)を加えて、そしてこれを−20℃で凍結して固体を分離した。液相を、NMR分析のために除去した。
