Definitions
- the present invention relates to a composition for improving biological metabolic parameters, comprising D-psicose as an active ingredient.
- the liver function index component value and the uric acid value are collectively referred to as a biological metabolism parameter.
- the liver is the largest glandular organ in the human body and an indispensable organ for living organisms.
- the liver is composed of a total of about 300 billion cells.
- Functional features of the liver include various biological reactions such as metabolic storage of nutrients, detoxification, phagocytosis of foreign substances and microorganisms, and regulation of blood circulation.
- Representative indicators of this liver function include various indicators such as ⁇ -GTP ( ⁇ -glutamyltransferase), ALT (alanine aminotransferase), AST (aspartate aminotransferase), ALP (alkaline phosphatase in serum). is there.
- ⁇ -GTP is an enzyme involved in drug metabolism in liver microsomes, and its numerical value increases due to cholestasis or alcoholic or drug-induced liver injury, and is therefore a test index used for screening of liver and biliary system functions.
- ALT is an aminotransferase that uses pyridoxal phosphate as a coenzyme, and is a typical liver function test index similar to ⁇ -GTP. ALT is particularly abundant in the liver, is less distributed to other organs than AST, and appears specifically in liver damage, so it is used as a disease index for hepatitis.
- AST like ALT, is an aminotransferase that uses pyridoxal phosphate as a coenzyme, and is a typical liver function test index.
- An increase in the serum concentration of ALP is considered to be an increase in synthesis from organ necrosis or regeneration after destruction, so this value is also used as one of the liver function evaluations.

- Non-Patent Document 1 D-psicose is low in calories (Patent Document 1, Non-Patent Documents 1 and 2) and hardly generates energy. When ingested by humans, 70% of it is absorbed as it is and excreted in the urine. It has been reported that the remaining 30% reaches the large intestine and is excreted in the stool with little utilization by intestinal bacteria. As the functionality, a postprandial blood glucose inhibitory effect (Non-Patent Document 2) has been reported, and the main mechanisms are inhibition of carbohydrate degradation, promotion of glucose uptake in the liver, and the like. Although characteristics such as fat reduction (Patent Document 2) have been clarified, the mechanism of action has not yet been clarified.

Abstract
Description
本発明において、肝機能の指標成分値と尿酸値をあわせて生体代謝パラメーターという。
この肝機能の代表的な指標としては、γ-GTP(γ-グルタミルトランスペプチダーゼ)、ALT(アラニンアミノトランスフェラーゼ)、AST(アスパラギン酸アミノトランスフェラーゼ)、ALP(血清中のアルカリフォスファターゼ)など種々の指標がある。
γ-GTPは、肝ミクロゾームにおける薬物代謝に関わる酵素で、その数値は、胆汁うっ滞又はアルコール性若しくは薬剤性肝障害により上昇するので、肝臓および胆道系機能のスクリーニングに用いる検査指標となる。
ALTは、ピリドキサールリン酸を補酵素とするアミノ基転移酵素で、γ-GTPと同じく代表的な肝機能の検査指標である。ALTは、特に肝臓に多く含まれており、ASTと比較して他臓器への分布が少なく、肝障害に特異的に現れるため、肝炎の病勢指標に用いられる。
ASTもALTと同じく、ピリドキサールリン酸を補酵素とするアミノ基転移酵素で、代表的な肝機能の検査指標である。肝細胞障害により血中に逸脱するが、骨格筋、心筋、赤血球などの破壊によっても数値が上昇する。
ALPの血清中における濃度上昇は、臓器の壊死や破壊後の再生からの合成亢進と考えられるため、この数値も肝機能評価の1つとして用いられる。
実際の肝臓障害判定では、1種類のみの増減ではなく、多種類のパラメーターの結果を見て総合的に判断するが、γ-GTPとALTの数値は、肝機能判断に特に優先度が高いと言われている。
一方で、尿酸値もまた、重要な生体代謝パラメーターであり、血中尿酸濃度が7mg/dLを超えると高尿酸血症となる。
また、尿酸値低下や肝疾患を効果的に治療できる薬剤、日々摂取することで尿酸値低下や肝機能障害を予防または治療できる健康飲食品または動物用飼料の開発が切望されている。本発明の目的は、尿酸値低下や肝機能保護剤または改善剤、尿酸値低下や肝機能保護または改善用飲食品、飼料、医薬品、尿酸値低下や肝機能保護作用または改善作用を有する飲食品用添加剤を提供することにある。

(6)肝機能保護または改善用飲食品、飼料、医薬品、医薬部外品、口腔用組成物、化粧品、または肝機能保護作用または改善作用を有する飲食品用添加剤である上記(1)ないし(4)のいずれかに記載の組成物。
また、本発明により、尿酸値低下や肝疾患を効果的に治療できる薬剤、日々摂取することで尿酸値低下や肝機能障害を予防または治療できる健康飲食品または動物用飼料を提供することができる。すなわち、尿酸値低下や肝機能保護剤または改善剤、尿酸値低下や肝機能保護または改善用飲食品、飼料、医薬品、尿酸値低下や肝機能保護作用または改善作用を有する飲食品用添加剤を提供することができる。
本発明のD-プシコース含有素材の機能を具体的に示すと、尿酸値や肝機能指標であるγ-GTP、AST、ALT、ALPの低下作用であり、そのことは肝細胞その他の保護効果を示す。
得られたD-プシコース液は、必要により、例えば、除蛋白、脱色、脱塩などの方法で精製され、濃縮してシラップ状のD-プシコース製品を採取することができ、さらに、カラムクロマトグラフィーで分画、精製することにより99%以上の高純度の標品も容易に得ることができる。このようなD-プシコースは単糖としてそのまま利用できる。

特に機能性を持たせた飲料としては、コーラなどの炭酸飲料、スポーツ飲料、果汁飲料、乳性飲料、茶系飲料などを挙げることができるが、特に大量飲用により肥満の問題の生ずる炭酸飲料が格好のターゲットと言うことができる。
本発明の組成物の、前記生体作用改善を目的とした食品素材あるいは食品添加物としての使用形態としては、錠剤、カプセル剤、飲料などに溶解させる粉末あるいは顆粒などの固形剤、ゼリーなどの半固形体、飲料水などの液体、希釈して用いる高濃度溶液などがある。

これらの治療剤および予防剤は、ヒト以外の動物、例えば、牛、馬、豚、羊などの家畜用哺乳類、鶏、ウズラ、ダチョウなどの家禽類、は虫類、鳥類或いは小型哺乳類などのペット類、養殖魚類などにも用いることができる。
日本においては、生活習慣病特に糖尿病の患者が増えていることが問題視されている。そこで、糖尿病に関わる被験者を募集し臨床試験を行いD-プシコースの生体代謝パラメーターの変動を検討した。被験者としては、糖尿病境界域被験者(空腹時血糖値が110~126mg/dl:12名)及び糖尿病患者(糖尿病の薬物治療を受けている2型糖尿病患者:6名)(同意取得時において20歳以上の男女)を募集した。摂取期間は12週間とし、摂取量としては、毎食5gD-プシコースとした。D-プシコースは株式会社希少糖生産技術研究所から購入した。検査日は、摂取開始日(0週)、摂取2週間後(2週)、摂取4週間後(4週)、摂取8週間後(8週)、摂取12週間後(12週)および摂取終了4週間後(16週:後観察期間)として、試験日前日の夕食以降は絶食とした。測定項目は、γ-GTP、ALT、ALP、尿酸値とし測定は株式会社BMLに委託した。統計は、摂取前後を対応のあるt検定で比較した。図中の有意差は、*:0.05<P、**:0.01<P
によって示した。
結果はγ-GTP、ALPについては図1-1、尿酸値については図1-2に示した。γ-GTPは摂取4週目から有意な低下を示した。ALPは、摂取2週目から有意な低下が認められた。
これらのことから、D-プシコース(5g/1回程度)の2~4週間程度の反復摂取によって、γGTP、ALPの明らかな減少が認められヒトにおいて生体機能のパラメーター(主に肝機能)が改善することが明らかとなった。また、糖尿病境界域、糖尿病患者と層別解析した結果、糖尿病境界域のγ-GTPでは摂取後4週目に有意な低下が(P<0.01)、糖尿病患者のγ-GTPでは摂取後8週目に有意な低下が(P<0.01)認められた。ALPに関しては、糖尿病境界域、糖尿病患者とも摂取後2週目から有意な低下が(P<0.05)認められた。これらのことから、糖尿病境界域、糖尿病患者のそれぞれにD-プシコースが有効であることが明らかとなった。検査値の減少程度から、1週間程度、もしくは今回の半量程度の摂取によっても効果があることが推察される。尿酸値に関しても、摂取2週目から有意な低下が認められた。層別解析では、糖尿病境界域の摂取2週目から有意な低下が認められたことから、特に糖尿病罹患前の状態でより効果が大きいことが推察される。
一方、ALTに有意な低下は認められなかったので、結果は示していない。
健常者(空腹時血糖値が110mg/dl:8名)及び糖尿病境界域被験者(空腹時血糖値が110~126mg/dl、或いはHbA1cが5.9~6.5%:6名)(同意取得時において20歳以上の男女)を集めてD-プシコースの4週間の摂取試験を行った。摂取量としては、1日1回15gのD-プシコース摂取とした。
D-プシコースは株式会社希少糖生産技術研究所から購入した。検査日は、摂取開始日(0週)、摂取2週間後(2週)、摂取4週間後(4週)、および摂取終了4週間後(8週:後観察期間)として、試験日前日の夕食以降は絶食とした。測定項目は、γ-GTP、ALT、ALPとし測定は株式会社第一臨床検査センターに委託した。統計は、摂取前後を対応のあるt検定で比較した。図中の有意差は、
*:0.05<P、**:0.01<P
によって示した。
結果は図2に示した。γ-GTP、ALT、ALP共に摂取2週目から有意な低下を示した。これらのことから、D-プシコース(15g/1日)の2週間程度の反復摂取によって、γGTP、ALT、ALPの明らかな減少が認められヒトにおいて生体機能のパラメーターが改善することが明らかとなった。特に、ALTは本試験での15g/1回の摂取により低下が認められたので、15g程度の摂取が必要であることが推察される。また、健常者、糖尿病患者と層別解析した結果、特に健常者のγ-GTP、ALPでは摂取後2週目に有意な低下が(P<0.01)認められた。検査値の減少程度から、1週間程度、もしくは今回の半量程度の摂取によっても効果があることが推察される。
実験動物として3週齢のWistar系雄性ラット(日本クレア株式会社)を1群7匹で14匹用いた。馴化期間の1週間は固形飼料CE-2(日本クレア株式会社)にて飼育した。馴化期間終了後に体重に準じて群分けを行った。飼料の基本組成は表1に示した。希少糖含有シロップは、異性化糖10%(w/v)溶液を、温度60℃、強塩基性イオン交換樹脂に送液し作成した(樹脂:アンバーライトIRA900J[Cl])。反応溶液の糖組成は、D-グルコース40%、D-フラクトース31%、D-プシコース7%、D-マンノース及びD-アロース等を含むその他糖質22%であった。
飼料ならびに飲料水は自由に摂取させ、それぞれ8週間飼育した。飼育終了後,エーテル麻酔下で順次ラットを開腹し、腎臓下の腹部大動脈よりヘパリン処理した注射器を用いて採血した。血漿の測定として、AST(GOT)、ALT(GPT)、尿酸値を市販キットにより測定した。実験データを平均値±標準誤差で示し、各群間の平均値の有意差検定については、対応の無いt検定を用いた。
表2に示す様に、AST、ALT、尿酸値に関して希少糖含有シロップを摂取させることで、有意な低下を示す結果が得られた。
これらのことから、アルカリ異性化により異性化糖を再異性化し、D-プシコースを含ませた組成物は、AST、ALT、尿酸値に対して改善傾向を示すことが明らかとなった。
