【発明の属する技術分野】
本発明は、疾患改善予防用液状組成物及びその製造方法、特に機能性食品を用いた疾患改善予防用液状組成物及びその製造方法の改良に関する。
【0002】
【従来の技術】
近年、食生活の多様性や美食ブームから一般的に若年層から肥満化の傾向にある。また、超高齢化社会やストレス化社会への突入に従って、加齢や生活習慣に関わる疾患が増加することが予測される。さらに循環系疾患の中でも高血圧症は肥満や運動不足から増加する傾向にある。
【0003】
遺伝的素因と日常生活上の不摂生(塩分の過剰摂取、ストレス、運動不足、アルコール、肥満など)以外に高血圧の原因が見つからない場合、本態性高血圧と呼ばれる。このタイプの高血圧は一般に中年以降に発症することが多く、糖尿病やその一歩手前である耐糖能障害、あるいは高脂血症・脂質代謝異常、肥満などの成人病を伴いやすいことが知られている。実際1kgの減量で血圧が1〜2mmHg低下するといわれている。
【0004】
従来の高血圧疾患に対する治療法としては、Ca拮抗薬、β受容体作動薬、アンギオテンシン転換酵素阻害薬を用いる方法が効果的であり、広範に用いられている。しかし、これらの薬物による長期治療での副作用の発現は、患者にとって治療を拒否する原因となっている。
また、肥満の改善方法としては、運動療法、食事療法が主流となっているが、いずれも継続が困難である。
このため、副作用を生じる可能性が低い自然食品や健康食品(機能性食品を含む)に対する関心が高まっている。
【0005】
【発明が解決しようとする課題】
しかしながら、従来の機能性食品においては、高血圧症、高脂血症及び肥満症等の改善・防止効果が必ずしも十分ではなく、より効果的な機能性食品が望まれていた。
本発明は、上記従来技術の課題に鑑みなされたものであり、その目的は、副作用を生じる可能性が低く、且つ優れた高血圧症、高脂血症及び肥満症等の改善・防止効果を持つ疾患改善予防用組成物、及びその製造方法を提供することにある。
【0006】
【課題を解決するための手段】
前記目的を達成するために、本発明者らが鋭意検討を行った結果、酵母を添加した植物抽出液を熟成発酵させた液状組成物は、優れた高血圧症、高脂血症及び肥満症等の改善・防止効果を持つことを見出し、本発明を完成するに至った。
【0007】
すなわち、本発明の第一の主題は、野菜、果物、海草、及び/又は穀物の酵母発酵物と、糖類を含み、酵母が寄託番号FERM P−18540の酵母であることを特徴とする高血圧症、高脂血症、肥満症改善予防用液状組成物である。
前記液状組成物において、糖度が50〜60%であることが好適である。
【0008】
本発明の第二の主題は、下記(A)〜(C)工程を含むことを特徴とする疾患改善予防用液状組成物の製造方法である。
(A) 野菜、果物、海草、及び/又は穀物に寄託番号FERM P−18540の酵母を添加する工程。
(B) 前記(A)工程後、糖類を添加し、原液を抽出する工程。
(C) 前記(B)工程後、原液を発酵・熟成する工程。
【0009】
【発明の実施の形態】
以下、本発明の好適な実施形態を詳細に説明する。
本発明の疾患改善予防用液状組成物において、原材料となるのは旬の物を中心とした野菜、果物、海草、及び穀物等である。
例えば、キャベツ、ホウレンソウ、ニンジン、パセリ、ナス、ピーマン、トマト、キュウリ、カブ、大根、春菊、小松菜、モロヘイヤ、蓮根、サツマイモ、ジャガイモ、ショウガ、リンゴ、ミカン、レモン、カキ、モモ、スイカ、ブドウ、ナシ、イチゴ、パイナップル、キウイ、バナナ、米、麦等が好適に用いられる。
【0010】
図1に示す製造方法について、詳しく説明する。
洗浄・水切り
初めに原材料となる野菜、果物、海草、及び穀物等を水で洗浄し、水切りする。この時使用する水は、清浄なものであれば特に限定されないが、塩素の含有量の少ない地下水等を使用することが好ましい。また、洗浄時には洗剤等を使用しないことが好ましい。
【0011】
仕込み・酵母添加
次に水切りした原材料を適当な大きさに刻み、容器に入れ、酵母を添加する。容器は発酵に適するものであれば特に制限されないが、木桶を使用することが好適である。また、原材料を刻む方法は特に限定されないが、栄養素の破壊を防止するため、刃物の使用は最小限にとどめることが好ましい。加熱に強い抽出物を得るために、酵母は寄託番号FERM P−18540の酵母を使用することが特に好適である。酵母の添加量は、その種類等にもより特に限定されないが、原材料1g当たり106〜107個程度であることが好適である。
なお、本発明にかかる酵母は、平成13年9月20日付でFERM P−18540として工業技術院生命工学工業技術研究所に受託されている。
【0012】

【0016】
糖添加・原液抽出
次に糖添加し、浸透圧により栄養素を破壊することなく、抽出する。また、抽出操作は常圧下、常温下で行うことが好ましいが、1〜5気圧、60〜150℃の加圧、加熱下で抽出してもよい。加える糖はブドウ糖、果糖、麦芽糖、乳糖、ショ糖、蜂蜜、エリスリトール等が好適である。添加量は、糖度30〜40%となるようにすることが好適である。30%より少ないと、腐敗する恐れがあり、40%より多いと、酵母の発酵を妨げてしまう。
【0017】
糖添加
さらに糖添加する。加える糖はブドウ糖、果糖、麦芽糖、乳糖、ショ糖、蜂蜜、エリスリトール等が好適である。添加量は抽出物に対して、50〜60質量%であることが好適である。50質量%より少ないと、腐敗する恐れがあり、60質量%より多いと、糖度が高すぎて本発明の効果が損なわれてしまう恐れがある。
以下の工程においては、糖度が50%未満とならないように調製することが好ましい。
【0018】
熟成発酵
次に熟成発酵させる。
熟成発酵の条件としては、15〜40℃、特に好ましくは20〜35℃の温度下で、1〜7時間、特に好ましくは2〜5時間熟成発酵させることが望ましい。である。15℃より低い温度、あるいは1時間より熟成発酵期間が短いと、本発明の効果が十分に発揮されず、40℃を越える温度、あるいは5時間より長く熟成発酵させても、本発明の効果がよりあがることは期待できない。
【0019】
原液熟成
さらに熟成させる。熟成の条件としては、2〜20℃、特に好ましくは5〜12℃の温度下で、15〜30時間、特に好ましくは18〜25時間熟成させることが望ましい。15時間より熟成期間が短いと、本発明の効果が十分に発揮されず、25時間より長く熟成させても、本発明の効果がよりあがることは期待できない。また、20℃を越える温度であると品質を損なう恐れがある。
【0020】
濾過・滅菌
次に原液を濾過し、雑菌を滅菌する。

【0023】
本発明の疾患改善予防用液状組成物には、本発明の趣旨に反しない公知の賦形剤や添加剤を必要に応じて適宜加えることができる。
本発明の疾患改善予防用液状組成物は、常法により加工して錠剤、カプセル剤、顆粒剤、散剤、液剤等の製剤とすることができる。
また、必要に応じて着色剤、芳香剤、矯味剤等を加えることもできる。
【0024】
本発明の疾患改善予防用液状組成物は経口投与して、高血圧症、高脂血症及び肥満症等の発症予防あるいは治療のために適用する。摂取量は症状により異なり特に限定されないが、成人(体重60kg)1日当たり1〜15ml、特に6〜9mlであることが好適である。1mlより少ないと所望の効果を奏することが難しくなり、15mlを越えて摂取してもさらなる効果は認められない場合がある。
【0025】
【実施例】
以下、実施例を挙げて本発明をさらに詳細に説明するが、本発明はこれに限定されるものではない。
1.高血圧症改善予防剤
(1)試験ラットの飼育、及び被験薬の投与方法
▲1▼予備飼育(6〜7週齢)
日本チャールスリバー(株)より購入した6週齢の雄性自然発症高血圧ラット(SHR)、及び正常血圧のウィスター京都ラット(WKY)を、室温22±1℃、湿度60±10%に調節された飼育室において、白色蛍光灯で1日12時間(7〜19時明期)の光調節を行い、飼料及び水道水を自由摂取させ1週間予備飼育した。
予備飼育後、各個体の体重測定及び血圧測定を行い、1群10頭とし、体重の平均値がほぼ等しくなるようにSHRラットをA〜D群に、WKYラットをE〜F群に分類した。
【0026】
▲2▼被験薬(液状組成物)の抽出方法
野菜、果物等の原材料5kgを洗浄し、水切りする。次に水切りした原材料を適当な大きさに刻み、容器に入れ、酵母(寄託番号FERM P−18540の酵母)を添加する。次にショ糖・麦芽糖を糖度50%となるよう添加し、浸透圧により原液を抽出する。さらに麦芽糖を糖度50%となるよう添加する。15℃下で5時間熟成発酵させる。さらに12℃下で25時間熟成させる。これを濾過し、100℃で30分滅菌する。
【0027】
▲3▼被験薬投与方法(8〜20週齢)
下記の要領で、各群のラットに被験薬投与を行い、8週齢からさらに12週間、20週齢まで飼育した。飼料と水道水を各群とも自由摂取させた。飼育室の環境は、温度22±1℃、湿度60±10%、白色蛍光灯で1日12時間の採光下(7〜19時明期)とした。
各被験薬はすべて経口投与とし、毎日午前10時より施行し、被験薬飲用後は滅菌水を自由摂取させた。なお、どの群においても被験薬投与により、飼料摂取量は変化しなかったが、水の摂取量は用量依存的に増加した。しかしながら、水の摂取量は9ml投与のD群においても、無投与のA、E群の2倍以内であった。
【0028】
A群:SHRラット:無投与
B群:SHRラット:1日に体重1kg当たり前記被験薬3mlを投与する。
C群:SHRラット:1日に体重1kg当たり前記被験薬6mlを投与する。
D群:SHRラット:1日に体重1kg当たり前記被験薬9mlを投与する。
E群:WKYラット:無投与
F群:WKYラット:1日に体重1kg当たり前記被験薬6mlを投与する。
【0029】
(2)結果
▲1▼血圧検査
血圧検査は週1回、被験薬投与前に行った。
結果を表1に示す。
【0030】
【0031】
表1より、SHRラット(A〜D群)はWKYラット(E〜F群)と比較して、血圧値が高かったが、SHRラット無投与群(A群)と比較して、9ml投与のD群では8週齢当たりから、6ml投与のC群では16週齢当たりから血圧上昇が抑制される傾向が見られた。また、WKYラットにおいても、19週齢当たりから血圧上昇が抑制される傾向が見られた。
よって、抽出物を投与することにより、用量依存的に高血圧治療効果があることがわかった。また、正常血圧である場合にも、加齢性の血圧上昇を抑制することがわかった。このように従来の高血圧治療薬のように単に血圧を下げるのではなく、血圧を正常値に近づける効果があり、より安全に服用できることがわかる。
【0032】
▲2▼血液検査
実験最終日の前日に全ラットを絶食させ、翌日に深麻酔(ネンブタール,45mg/kg,i.p.)し、左心室から20G採血針で可能な限り採血を行った。
採取した血液を用いて、下記の項目において生化学的検査(自動化学分析装置:Auto Lab, Radio lmmuno Assay 法)を行った。得られた成績は、群間比較をWilcoxon U-testで解析し、1%以内の危険率を持って有意差があると判定した(p<0.05)。なお、すべての値は平均値と標準誤差値で表示した。
結果を表2に示す。
【0033】
【0034】
総コレステロール、遊離コレステロール、HDL−Cho、LDL−Cho
表2より、SHRラット(A〜D群)はWKYラット(E〜F群)と比較して、遊離コレステロール、及びLDL−Choの値が高いことがわかった。
コレステロールは、生体細胞膜の構成成分として細胞の形態・機能の維持およびステロイドホルモン、胆汁酸の前駆物質として必須の成分である。血液中コレステロールの70%はエステル型で、残りが遊離型として存在するが、その和を総コレステロールと呼んでいる。
【0035】
遊離コレステロールは、血中に存在している総コレステロールの一部であり、 Tchoの約70%がエステル型、残りの約30%がFchoとして存在する。 Fchoを測定することで、脂質代謝異常をきたす疾患の推測ができる。
またコレステロールは、善玉コレステロール(HDL−Cho)と、悪玉コレステロール(LDL−Cho)とに分けられる。LDL−Choは動脈硬化を促進し、HDL−Choは血管壁に付着したLDL−Choを取り除く働きをする。
よって、これらを測定することにより、脂質代謝異常をきたす疾患の推測ができる。
【0036】
A群と比較して、C、D群では遊離コレステロール、及びLDL−Choの低下が見られ、E群の値に近づいた。一方、善玉コレステロールであるHDL−Choは低下することがなかった。また、正常ラットである場合には抽出液投与により、これらの値には目立った変化(異常)を示さなかった。
よって、高血圧治療効果に伴い、脂質代謝異常の改善効果を有することが推察される。
【0037】
中性脂肪
表2より、SHRラット(A〜D群)はWKYラット(E〜F群)と比較して、中性脂肪値が高いことがわかった。
中性脂肪は、蛋白と結合して水溶性のリポ蛋白として存在する。 中性脂肪の測定は、脂質代謝異常をきたす疾患の診断、予後の判定などの指標として実施される。
A群と比較して、C、D群では中性脂肪の低下が見られ、E群の値に近づいた。また、正常ラットである場合には抽出液投与により、中性脂肪の値には目立った変化(異常)を示さなかった。
よって、中性脂肪値の測定においても、高血圧治療効果に伴い、脂質代謝異常の改善効果を有することが確認された。

尿素窒素、クレアチニン、尿酸
表2より、SHRラット(A〜D群)はWKYラット(E〜F群)と比較して、尿素窒素、クレアチニン、尿酸の値が高いことがわかった。
尿素窒素は、蛋白の最終代謝産物である尿素中の窒素のことである。 尿素は肝で尿素サイクルを経て生成する窒素成分で、血中に放出され腎臓から排泄される。 尿素窒素値は、食品として摂取される蛋白および異化蛋白量と腎臓での排泄量に支配されており、肝・腎機能の指標となる。
【0040】
クレアチニンは、血中非蛋白性窒素化合物の1つである。 尿素や尿酸などと同様に腎を介して尿中に排泄される。 クレアチニンの測定は、腎機能の指標に用いられる。
【0041】
尿酸は肝臓、筋肉、骨髄で生成される核酸構成成分であるプリン体の最終代謝産物である。 尿酸は組織で分解され、少量は胆汁・腸に、大部分は尿中に排泄される。 尿酸の測定は、腎臓における尿酸排泄異常の診断に利用される。
尿素窒素値は、A群と比較して、D群では低下が確認され、E群の値に近づいた。クレアチニン値は、A群と比較して、B〜D群、特にD群では低下する傾向が見られ、E群の値に近づいた。尿酸値は、A群と比較して、B〜D群ではの低下が見られ、E群の値に近づいた。一方、正常ラットである場合には抽出液投与により、これらの値には目立った変化(異常)を示さなかった。
よって、高血圧治療効果に伴い、肝・腎機能の改善も見られることが確認された。
【0042】
A/G比、白血球数
表2より、SHRラット(A〜D群)はWKYラット(E〜F群)と比較して、A/G比、白血球数が低いことがわかった。
A/G比は、血漿蛋白であるアルブミン(Alb)と総グロブリン(Glob)の比率であり、 その値はAlbとGlobの相対的変動に依存する。 A/G比は体内の蛋白質代謝の指標として利用されるが、臨床的に問題となるのは、 A/G比の低下であり、A/G比を知ることで全身の一般状態を推測できる。
A/G比は、A群と比較して、B〜D群ではA/G比が上昇する傾向が見られ、E群の値に近づいた。
【0043】
また、白血球数はA群と比較して、B〜D群では上昇が見られた。
一方、正常ラットである場合には抽出液投与により、これらの値には目立った変化(異常)を示さなかった。
よって、これらのパラメーターの改善効果は高血圧治療効果の強い群と密接な関連を有することが推察される。
【0044】
また、抽出液投与によって、総タンパク、アルブミン等には異常をきたすことはなかった。
よって血液検査から、本発明にかかる疾患改善予防用液状組成物投与により血圧降下作用を示しても、血液成分には異常をきたさないことが確認された。

In recent years, due to the diversity of eating habits and the gastronomy boom, there has been a general trend toward obesity from a younger age group. Moreover, it is predicted that diseases related to aging and lifestyle will increase in accordance with the entry into a super-aging society and stressed society. Furthermore, among circulatory diseases, hypertension tends to increase due to obesity and lack of exercise.
[0003]
If the cause of hypertension is not found other than genetic predisposition and non-perturbation in daily life (excess salt intake, stress, lack of exercise, alcohol, obesity, etc.), it is called essential hypertension. This type of hypertension generally occurs after middle age, and is known to be easily associated with diabetes, impaired glucose tolerance, or hyperlipidemia, abnormal lipid metabolism, obesity, etc. Yes. In fact, it is said that the blood pressure is reduced by 1 to 2 mmHg with a weight loss of 1 kg.
[0004]
As a conventional treatment method for hypertensive diseases, a method using a Ca antagonist, a β receptor agonist, and an angiotensin converting enzyme inhibitor is effective and widely used. However, the occurrence of side effects in the long-term treatment with these drugs causes the patient to refuse treatment.
Moreover, exercise therapy and diet therapy are mainstream as methods for improving obesity, but both are difficult to continue.
For this reason, there is an increasing interest in natural foods and health foods (including functional foods) that are less likely to cause side effects.
[0005]
[Problems to be solved by the invention]
However, conventional functional foods are not necessarily sufficient for improving and preventing hypertension, hyperlipidemia, obesity and the like, and more effective functional foods have been desired.

It is. If the aging fermentation period is shorter than 15 ° C. or shorter than 1 hour, the effect of the present invention is not sufficiently exhibited. Even if the aging fermentation is performed at a temperature exceeding 40 ° C. or longer than 5 hours, the effect of the present invention can be obtained. I can't expect to go further.
[0019]
Stock solution aging
Aged further. As aging conditions, it is desirable to age at a temperature of 2 to 20 ° C., particularly preferably 5 to 12 ° C. for 15 to 30 hours, particularly preferably 18 to 25 hours. If the aging period is shorter than 15 hours, the effect of the present invention is not sufficiently exerted, and even if the aging time is longer than 25 hours, it cannot be expected that the effect of the present invention is further improved. Further, if the temperature exceeds 20 ° C., the quality may be impaired.
[0020]
Filtration / sterilization
The stock solution is then filtered to sterilize the germs.
The sterilization conditions are preferably a temperature of 90 to 130 ° C. and a time of 1 second to 5 minutes. If the temperature is less than 90 ° C. or less than 1 second, miscellaneous bacteria cannot be sufficiently sterilized, and if the temperature exceeds 130 ° C. or longer than 5 minutes, the effect of the present invention may be diminished.

If it is less than 1 ml, it will be difficult to achieve the desired effect, and even if it exceeds 15 ml, no further effect may be observed.
[0025]
【Example】
EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated further in detail, this invention is not limited to this.
1. Antihypertensive agent
(1) Rearing of test rats and administration of test drug
(1) Preliminary breeding (6-7 weeks old)
Breeding 6-week-old male spontaneously hypertensive rats (SHR) and normal blood pressure Wistar Kyoto rats (WKY) purchased from Nippon Charles River Co., Ltd., adjusted to room temperature 22 ± 1 ° C. and humidity 60 ± 10%. In the room, light adjustment was performed for 12 hours a day (7-19 o'clock light period) with a white fluorescent lamp, and feed and tap water were freely ingested and preliminarily raised for 1 week.
After pre-breeding, each individual was weighed and blood pressure was measured, and 10 animals were grouped. SHR rats were classified into groups A to D and WKY rats were grouped into groups E to F so that the average values of body weights were almost equal. .
[0026]
(2) Extraction method of test drug (liquid composition)
Wash 5 kg of raw materials such as vegetables and fruits and drain. Next, the drained raw material is chopped to an appropriate size, placed in a container, and yeast (yeast with deposit number FERM P-18540) is added. Next, sucrose / malt sugar is added to a sugar content of 50%, and the stock solution is extracted by osmotic pressure. Furthermore, malt sugar is added so that the sugar content is 50%. Aged and fermented at 15 ° C for 5 hours. It is further aged for 25 hours at 12 ° C. This is filtered and sterilized at 100 ° C. for 30 minutes.
[0027]
(3) Test drug administration method (8-20 weeks old)
In the following manner, each group of rats was administered a test drug and reared from 8 weeks of age to 12 weeks and 20 weeks of age. Feed and tap water were freely given to each group. The environment of the breeding room was a temperature of 22 ± 1 ° C., a humidity of 60 ± 10%, and white fluorescent lighting for 12 hours a day (7-19 o'clock light period).
Each test drug was administered orally, and was conducted every day from 10:00 am. After taking the test drug, sterilized water was ingested freely. In any group, the feed intake did not change with the administration of the test drug, but the water intake increased in a dose-dependent manner. However, the amount of water intake was within twice that of the non-administered groups A and E even in group 9 administered 9 ml.
[0028]
Group A: SHR rats: no administration
Group B: SHR rat: 3 ml of the test drug is administered per kg body weight per day.
Group C: SHR rats: 6 ml of the test drug is administered per kg body weight per day.
Group D: SHR rats: Administer 9 ml of the test drug per kg of body weight per day.
Group E: WKY rats: no administration
Group F: WKY rat: 6 ml of the test drug is administered per kg body weight per day.
[0029]
(2) Results
▲ 1 Blood pressure test
The blood pressure test was performed once a week before administration of the test drug.
The results are shown in Table 1.
[0030]
[0031]
From Table 1, SHR rats (Groups A to D) had higher blood pressure values compared to WKY rats (Groups E to F), but compared to the SHR rats non-administered group (Group A), The increase in blood pressure tended to be suppressed from around 8 weeks of age in Group D and from around 16 weeks of age in Group C administered with 6 ml. Moreover, also in the WKY rat, the tendency for the blood pressure rise to be suppressed from around 19 weeks of age was observed.
Therefore, it was found that administration of the extract has a hypertension treatment effect in a dose-dependent manner. Further, it was found that even when the blood pressure is normal blood pressure, the increase in age-related blood pressure is suppressed. Thus, it is understood that the blood pressure is not simply lowered as in the case of conventional antihypertensive drugs, but has an effect of bringing the blood pressure close to a normal value and can be taken more safely.
[0032]
(2) Blood test
The day before the last day of the experiment, all rats were fasted, and the next day, deep anesthesia (Nembutal, 45 mg / kg, i.p.) was taken, and blood was collected from the left ventricle as much as possible with a 20 G blood collection needle.
Using the collected blood, biochemical tests (automatic chemical analyzer: Auto Lab, Radio lmmuno Assay method) were performed on the following items. The obtained results were analyzed by the Wilcoxon U-test for comparison between groups, and judged to have a significant difference with a risk rate within 1% (p <0.05). All values were expressed as average values and standard error values.
The results are shown in Table 2.
[0033]
[0034]
Total cholesterol, free cholesterol, HDL-Cho, LDL-Cho
From Table 2, it was found that SHR rats (Groups A to D) had higher values of free cholesterol and LDL-Cho than WKY rats (Groups E to F).
Cholesterol is an essential component for maintaining cell morphology and function as a constituent of biological cell membranes and as a precursor for steroid hormones and bile acids. 70% of blood cholesterol is in the ester form and the rest is in free form, but the sum is called total cholesterol.
[0035]
Free cholesterol is part of the total cholesterol present in the blood, with approximately 70% of the Tcho present as the ester form and the remaining approximately 30% as the Fcho. By measuring Fcho, it is possible to estimate a disease that causes abnormal lipid metabolism.
Cholesterol is classified into good cholesterol (HDL-Cho) and bad cholesterol (LDL-Cho). LDL-Cho promotes arteriosclerosis, and HDL-Cho works to remove LDL-Cho attached to the blood vessel wall.
Therefore, by measuring these, it is possible to estimate a disease that causes abnormal lipid metabolism.
[0036]
Compared with the A group, the C and D groups showed a decrease in free cholesterol and LDL-Cho, approaching the values of the E group. On the other hand, HDL-Cho, which is good cholesterol, did not decrease. In the case of normal rats, no significant change (abnormality) was observed in these values after administration of the extract.
Therefore, it is guessed that it has the improvement effect of lipid metabolism abnormality with the hypertension treatment effect.
[0037]
Neutral fat
From Table 2, it was found that SHR rats (A to D group) had higher triglyceride values than WKY rats (E to F group).
Neutral fat binds to protein and exists as water-soluble lipoprotein. Neutral fat is measured as an indicator for diagnosis of diseases causing abnormal lipid metabolism, determination of prognosis, and the like.
Compared with the A group, a decrease in neutral fat was observed in the C and D groups, approaching the values of the E group. Further, in the case of normal rats, no significant change (abnormality) was observed in the value of neutral fat by administration of the extract.
Therefore, it was confirmed that the measurement of triglyceride levels also has an effect of improving lipid metabolism abnormalities with the effect of treating hypertension.
[0038]
β-lipoprotein
From Table 2, it was found that the SHR rats (A to D groups) had higher β lipoprotein values than the WKY rats (E to F groups).
β-lipoprotein is a general term for lipoproteins that migrate to the β-position by electrophoresis. The main function is to transport cholesterol from the liver to each organ. β-lipoprotein measurement is used as an indicator of diseases of abnormal lipid metabolism such as hyperlipoprotein leukemia.
Compared with the A group, a decrease in the β lipoprotein value was observed in the BD groups, approaching the value of the E group. On the other hand, in the case of normal rats, the administration of the extract showed no noticeable change (abnormality) in the β lipoprotein level.
Therefore, it was confirmed that improvement in lipid metabolism abnormality was also observed in the β lipoprotein level with the effect of hypertension treatment.
[0039]
Urea nitrogen, creatinine, uric acid
From Table 2, it was found that SHR rats (Groups A to D) had higher values of urea nitrogen, creatinine, and uric acid than WKY rats (Groups E to F).
Urea nitrogen is nitrogen in urea, which is the final metabolite of protein. Urea is a nitrogen component produced through the urea cycle in the liver, and is released into the blood and excreted from the kidney. The urea nitrogen level is governed by the amount of protein and catabolic protein ingested as food and the amount excreted in the kidney, and is an index of liver / kidney function.
[0040]
Creatinine is one of the non-protein nitrogen compounds in blood. It is excreted in the urine via the kidney like urea and uric acid. Measurement of creatinine is used as an indicator of renal function.
[0041]
Uric acid is the final metabolite of purines, which are nucleic acid components produced in the liver, muscle, and bone marrow. Uric acid is broken down in tissues, and a small amount is excreted in bile / intestine and most in urine. The measurement of uric acid is used for diagnosis of abnormal uric acid excretion in the kidney.
Compared with the A group, the urea nitrogen value was confirmed to decrease in the D group and approached the value of the E group. The creatinine value tended to decrease in the B to D groups, particularly the D group, as compared with the A group, and approached the value of the E group. The uric acid level decreased in the B to D groups compared to the A group, and approached the E group value. On the other hand, in the case of normal rats, no significant change (abnormality) was observed in these values after the administration of the extract.
Therefore, it was confirmed that improvement of liver / kidney function was observed with the effect of hypertension treatment.
[0042]
A / G ratio, white blood cell count
From Table 2, it was found that SHR rats (Groups A to D) had lower A / G ratios and white blood cell counts than WKY rats (Groups E to F).
The A / G ratio is the ratio of plasma protein albumin (Alb) to total globulin (Glob), and its value depends on the relative fluctuation of Alb and Glob. The A / G ratio is used as an index of protein metabolism in the body, but the clinical problem is a decrease in the A / G ratio, and the general state of the whole body can be estimated by knowing the A / G ratio. .
The A / G ratio tended to increase in the BD groups compared to the A group, and approached the value of the E group.
[0043]
In addition, the leukocyte count increased in the BD groups compared to the A group.
On the other hand, in the case of normal rats, no significant change (abnormality) was observed in these values after the administration of the extract.
Therefore, it is inferred that the improvement effect of these parameters is closely related to the group with strong antihypertensive effect.
[0044]
In addition, administration of the extract did not cause abnormalities in total protein, albumin, and the like.
Therefore, it was confirmed from the blood test that even if the blood pressure-lowering effect was exhibited by administration of the liquid composition for preventing disease according to the present invention, the blood components were not abnormal.
[0045]
2. Anti-obesity agent
The inherited form of Zucker rats is an autosomal simple recessive inheritance pattern, and only individuals (fa / fa) that have a homologous etiology gene (fa gene) are obese (Zucker-fatty rats: (ZUC) -fa / fa), heterozygotes (fa / +) and wild type (+ / +) do not exhibit obesity (Zucker-lean rats: (ZUC) -lean). Zucker-fatty rats are obese by weight gain and appearance from around 4 weeks of age. Obesity progresses rapidly by around 10 weeks of age, and then gradually progresses thereafter. Furthermore, it is known to show hyperlipidemia, hyperinsulinemia, hyperleptinemia and abnormal glucose tolerance. Using this Zucker-fatty rat and a Zucker-lean rat as a comparison, the effect of improving obesity was tested.
[0046]
(1) Rearing of test rats and administration of test drug
(1) Preliminary breeding (5-6 weeks old)
A 5-week-old male Zucker fatty rat and male Zucker-lean rat purchased from Nippon Charles River Co., Ltd. were placed in a breeding room adjusted to room temperature 22 ± 1 ° C and humidity 60 ± 10% with a white fluorescent lamp. Light adjustment was carried out for 12 hours a day (7-19 o'clock light period), and feed and tap water were freely taken and pre-bred for 1 week.
After preliminary breeding, the weight of each individual was measured to make 5 animals in one group, and Zucker fatty rats were classified into G to K groups and Zucker-lean rats were classified into L to M groups so that the average values of body weights were almost equal. .
[0047]
(2) Extraction method of test drug (liquid composition)
Wash 5 kg of raw materials such as vegetables and fruits and drain. Next, the drained raw material is chopped to an appropriate size, placed in a container, and yeast (yeast with deposit number FERM P-18540) is added. Next, sucrose / malt sugar is added to a sugar content of 50%, and the stock solution is extracted by osmotic pressure. Furthermore, malt sugar is added so that the sugar content is 50%. Aged and fermented at 15 ° C for 5 hours. It is further aged for 25 hours at 12 ° C. This is filtered and sterilized at 100 ° C. for 30 minutes.
[0048]
(3) Test drug administration method (6 to 16 weeks of age)
The test drug was administered to each group of rats in the following manner and further reared for 10 weeks to 16 weeks of age. Feed and tap water were freely given to each group. The environment of the breeding room was a temperature of 22 ± 1 ° C., a humidity of 60 ± 10%, and white fluorescent lighting for 12 hours a day (7-19 o'clock light period).
Each test drug was administered orally, and was conducted every day from 10:00 am. After taking the test drug, sterilized water was ingested freely. In any group, the feed intake did not change with the administration of the test drug, but the water intake increased in a dose-dependent manner. However, the amount of water intake was within twice that of the untreated G and L groups even in the 12 ml administered K group.
[0049]
Group G: Zucker-fatty rat: No administration
Group H: Zucker-fatty rat: 3 ml of the test drug is administered per kg of body weight per day.
Group I: Zucker-fatty rat: 6 ml of the test drug is administered per kg of body weight per day.
Group J: Zucker-fatty rat: Administer 9 ml of the test drug per kg of body weight per day.
Group K: Zucker-fatty rat: 12 ml of the test drug is administered per kg of body weight per day.
L group: Zucker-lean rat: No administration
Group M: Zucker-lean rat: 6 ml of the test drug is administered per kg of body weight per day.
[0050]
(2) Results
▲ 1 ▼ Weight fluctuation
Body weight was measured once a week before administration of the test drug. The average value of the body weight of each group of rats was determined. The results are shown in Table 3.
[0051]
From Table 3, the Zucker-fatty rats (G to K groups) showed a significant increase in body weight compared to the Zucker-lean rats (L to M groups). In comparison, suppression of weight gain was observed from the age of 8 weeks in the administration group (H to K group). The inhibitory effect on weight gain was higher in the higher dose group.
In addition, in Zucker-lean rats having normal weight, suppression (abnormal) of weight gain was not observed.
Therefore, it was found that administration of the extract shows an effect of suppressing obesity in a dose-dependent manner. Moreover, since the weight gain inhibitory effect works only in the case of obesity, it was confirmed that taking is safe.
[0052]
(2) Blood test
The day before the last day of the experiment, all rats were fasted, and the next day, deep anesthesia (Nembutal, 45 mg / kg, i.p.) was taken, and blood was collected from the left ventricle as much as possible with a 20 G blood collection needle.
Using the collected blood, biochemical tests (automatic chemical analyzer: Auto Lab, Radio lmmuno Assay method) were performed on the following items. The obtained results were analyzed by Wilcoxon U-test for comparison between groups, and judged to have a significant difference with a risk rate within 1% (p <0.05). All values were expressed as average values and standard error values.
The results are shown in Table 4.
[0053]
[0054]
Neutral fat, phospholipid, total lipid
From Table 4, it was found that Zucker-fatty rats (G to K group) had higher values of neutral fat, phospholipid, and total lipid than Zucker-lean rats (L to M group).
As described above, measurement of neutral fat is performed as an index for diagnosis of a disease causing abnormal lipid metabolism, determination of prognosis, and the like.
[0055]
Phospholipids are involved in maintaining membrane permeability as a constituent of cell membranes in vivo. Phospholipids in blood are synthesized mainly in the liver and secreted into the blood as a surface component of lipoproteins.
Total lipid is the sum of total cholesterol, neutral fat, free fatty acid, phospholipid, and the like, which are lipid components in blood. Measurement of total lipids is important to gain a comprehensive understanding of lipid metabolism.
[0056]
Compared with the G group, the HK group showed a decrease in neutral fat, phospholipid, and total lipid in a dose-dependent manner, approaching the values of the L group. Moreover, although the phospholipid important as a component of the cell membrane was reduced, the decrease was small compared with the neutral fat and the total lipid, and it was not less than the value of the L group.
[0057]
Moreover, there was no remarkable change (abnormality) in these values in Zucker-lean rats (normal rats).
Therefore, it was confirmed that the lipid metabolism was improved with the obesity suppressing effect.
[0058]
Total cholesterol, free cholesterol, HDL-Cho
From Table 4, it was found that Zucker-fatty rats (G to K group) had higher values of total cholesterol and free cholesterol than Zucker-lean rats (L to M group).
By measuring the cholesterol level as described above, it is possible to estimate a disease that causes abnormal lipid metabolism.
Compared with the G group, the total cholesterol and free cholesterol decreased in the HK group. Moreover, with respect to the decrease in these values, the value of HDL-Cho, which is good cholesterol, did not decrease, but rather increased. Moreover, there was no remarkable change (abnormality) in these values in Zucker-lean rats (normal rats).
Therefore, improvement in lipid metabolism was also confirmed in the cholesterol level with the obesity suppressing effect.
[0059]
β-lipoprotein
From Table 4, it was confirmed that Zucker-fatty rats (G to K group) had higher β lipoprotein values than Zucker-lean rats (L to M groups).
As described above, β-lipoprotein measurement is used as an indicator of diseases of abnormal lipid metabolism such as hyperlipoprotein leukemia.
Compared with group G, the H-K group showed a decrease in β-lipoprotein level in a dose-dependent manner, approaching that of group L. Therefore, it was confirmed that improvement in lipid metabolism abnormality was also observed in the β lipoprotein level with the obesity suppressing effect.
[0060]
Creatinine
From Table 4, it was found that Zucker-fatty rats (G to K group) had lower creatinine values than Zucker-lean rats (L to M groups).
As described above, the measurement of creatinine is used as an index of renal function.
Compared with group G, creatinine levels increased in a dose-dependent manner in groups HK. Therefore, it was confirmed that the renal function was improved along with the obesity suppressing effect.
[0061]
Further, administration of the extract did not cause abnormalities in total protein, albumin, A / G ratio, urea nitrogen value, and the like.
Therefore, it was confirmed from the blood test that the blood component was improved with the obesity suppression effect by administration of the liquid composition for preventing disease prevention of the present invention, and that normal values were not abnormal.
[0062]
