Description

本発明は、安全な抗老化経口剤に関する。   The present invention relates to a safe anti-aging oral preparation.

戦前、戦後の貧しい食事パターンの時代の主要な死因は感染症や脳卒中であったが、経済の高度成長期を境に食が豊かになると、総摂取エネルギーに対する脂質エネルギー比率が高くなり、動物性脂質摂取やリノール酸の摂取増加、身体活動量の低下を背景として、内臓脂肪型肥満を基礎とした代謝障害が増加し、主要な死因は悪性新生物、心血管疾患や脳血管疾患が上位を占める構造に変化した。特に内臓脂肪に起因する炎症反応と、それによってもたらされる代謝障害が問題視され、健康寿命を延ばすための研究が多く実施されている。   The main causes of death in the period of poor dietary patterns before and after the war were infections and strokes, but when food became abundant during the period of high economic growth, the ratio of lipid energy to total intake energy increased, resulting in animal nature. Metabolic disorders based on visceral fat obesity increase against the backdrop of increased intake of lipid and linoleic acid, and decreased physical activity, leading to the leading causes of malignant neoplasms, cardiovascular diseases and cerebrovascular diseases The structure has changed. In particular, inflammatory reactions caused by visceral fat and metabolic disorders caused thereby are regarded as problems, and many studies for extending healthy life span have been conducted.

IGF−1は中枢神経疾患(アルツハイマー病などの認知症など)、心血管系疾患(心筋梗塞、脳梗塞、高血圧など)、代謝異常疾患(肥満、糖尿病、脂質異常症など)、消化器・内臓疾患(潰瘍、肝機能低下など)、運動器疾患(関節リウマチ、関節炎など)、皮膚化領域疾患(皮膚老化、脱毛など)、免疫賦活作用(NK細胞活性化など)など、多岐に渡り関与することが知られている。例えば、インスリン様成長因子(IGF−1)のレベル上昇による内臓脂肪の低下方法のようにIGF−1のレベルを高める技術(特許文献1)をはじめ、抗老化や疾病予防、治療などへの応用としてのIGF−1の利用が注目されている。   IGF-1 is a central nervous disease (dementia such as Alzheimer's disease), cardiovascular disease (myocardial infarction, cerebral infarction, hypertension, etc.), metabolic disorder (obesity, diabetes, dyslipidemia, etc.), digestive organs / internal organs Involved in various areas such as diseases (ulcers, decreased liver function), motor organ diseases (rheumatoid arthritis, arthritis, etc.), skin diseases (skin aging, hair loss, etc.), immunostimulatory effects (NK cell activation, etc.) It is known. For example, the technology for increasing the level of IGF-1 (Patent Document 1), such as a method for reducing visceral fat by increasing the level of insulin-like growth factor (IGF-1), as well as its application to anti-aging, disease prevention, treatment, etc. The use of IGF-1 as a

ヒトや動物(ウシや豚など)由来や人工的に合成されたIGF−1そのものを投与することは、ポリペプチドであるIGF−1の特性上、経口的に投与することは困難であり、注射剤として使用されている。しかしながら、注射剤の場合は、医師の監視下で行われるため、汎用性のある手段とはいえず、製剤に混入する不純物によっては副作用をきたす可能性もあり、一般的に利用するには問題があった。   It is difficult to administer IGF-1 itself, which is derived from humans and animals (such as cows and pigs) or artificially synthesized, because of the properties of IGF-1, which is a polypeptide. It is used as an agent. However, in the case of injections, since it is performed under the supervision of a doctor, it cannot be said to be a versatile means, and depending on the impurities mixed in the preparation, there is a possibility of causing side effects, which is a problem for general use. was there.

安全性を重視して、生体が本来もっている機能を賦活化してIGF−1レベルを高める技術が公開されている。具体的なIGF−1の有用性に関連した先行技術は、例えば、糖尿病に有効な組成物として食品たんぱく質を利用し、生体内でIGF−1を誘導する技術(特許文献2)、同じく食品たんぱく質を利用するものとして、加齢に伴う諸症状(肌荒れ、肌艶、肌の張りの低下、しみ、そばかすの増加、気力の低下など)の緩和としてサケの卵巣膜をプロテアーゼ処理し抽出したIGF−1値上昇剤(特許文献3)、肌荒れ改良剤(特許文献4)、末梢血液循環を改善する加速度脈波加齢指数上昇剤(特許文献5)がある。また、カルシトニン遺伝子関連ペプチドを介してIGF−1を誘導するカルシトニン遺伝子関連ペプチド産生及び放出促進作用を有する胃粘膜傷害予防・治療用可食性組成物および育毛用可食性組成物(特許文献6)、育毛や美容効果を持った植物由来の苦味配糖体ゲンチオピクリンを含んだIGF−1産生促進剤(特許文献7)、老化による皮膚のしわ、たるみを軽減するα-D-グルコピラノシルグリセロールを含有するIGF−1産生促進剤(特許文献8)が公知となっている。   A technique that raises the IGF-1 level by activating the functions inherent to the living body with an emphasis on safety is disclosed. Specific prior arts related to the usefulness of IGF-1 include, for example, a technique that uses food protein as a composition effective for diabetes and induces IGF-1 in vivo (Patent Document 2), and also a food protein. IGF- extracted from salmon ovarian membrane with protease treatment to relieve various symptoms associated with aging (roughness, skin gloss, decreased skin tension, blots, freckles, decreased energy, etc.) There are 1-value elevating agents (Patent Document 3), rough skin improving agents (Patent Document 4), and acceleration pulse wave aging index elevating agents (Patent Document 5) that improve peripheral blood circulation. In addition, an edible composition for preventing and treating gastric mucosal injury and an edible composition for hair growth having a calcitonin gene-related peptide production and release promoting action that induces IGF-1 via a calcitonin gene-related peptide (Patent Document 6), IGF-1 production promoter containing plant-derived bitter glycoside gentiopicrin with hair growth and beauty effects (Patent Document 7), α-D-glucopyranosyl that reduces skin wrinkles and sagging due to aging An IGF-1 production promoter containing glycerol (Patent Document 8) is known.

しかしながら、食品たんぱく質をベースとしたものや苦味配糖体、イソフラボノイド類、カプサイシンなどIGF−1産生を促進する従来技術は、におい、苦味、辛味、渋みなどの特徴から利用を継続するにはなお課題を残していた。
また、IGF−1を産生促進するために多量の炭酸ガスナノバブルを発生させる技術として、血流量およびインスリン様成長因子増加装置、並びに血流量およびインスリン様成長因子増加方法(特許文献9)が公知となっているが、コストの面から、汎用性に問題がある。
However, conventional technologies that promote IGF-1 production, such as food protein-based products, bitter glycosides, isoflavonoids, capsaicin, etc., cannot be continued due to characteristics such as smell, bitterness, pungent taste, and astringency. I left a challenge.
Further, as a technique for generating a large amount of carbon dioxide nanobubbles in order to promote production of IGF-1, a blood flow volume and insulin-like growth factor increasing device and a blood flow volume and insulin-like growth factor increasing method (Patent Document 9) are known. However, there is a problem in versatility from the viewpoint of cost.

<Example of preparation of ASG fraction>
After removing neutral lipids in the lipid component from brown rice bran and germinated brown rice bran with hexane, a crude extract of ASG fraction was prepared for each residue using hexane, chloroform and methanol. This ASG extract was extracted with a chloroform: methanol (2: 1) mixture, and the ASG fraction was prepared by silica gel carrier column chromatography. Extraction of the ASG fraction used in the test was carried out using 200 kg of koji (koji accuracy 10%) obtained by scouring about 2,000 kg of germinated brown rice.
An amount of hexane soaked with rice bran (500 g) was added and stirred sufficiently, followed by filtration with gauze to obtain a defatted koji. After that, the defatted soot from which hexane is volatilized is added to 1.5 kg of chloroform: methanol 2: 1 (3 L) to extract the total lipid fraction (TL), and the extract is dried to dryness with an evaporator. Obtained.

採取した暗緑色の溶液はエバポレーターで乾固させ試験に供した。以下に各ポイントでの収量を示す。
The dried product was dissolved in 300 ml of chloroform: hexane = 1: 1, and the whole solution was applied to a column of 10 cm in diameter and 100 cm in length (packed with 80 cm of Merck silica gel 60) swollen with chloroform. After all the solution had soaked into the iatrobeads, chloroform: hexane = 1: 1 (7,840 ml), chloroform (20,160 ml), chloroform: methanol = 9: 1 (10,080 ml) were passed in this order. Only a dark green solution separated by passing chloroform: methanol = 9: 1 was collected.
The collected dark green solution was dried to dryness using an evaporator. The yield at each point is shown below.

<Animal test (1)>
[Test animals and feed]
For the test, 8-week-old male senescence accelerated mice (SAMP-8) were used. The test feed was prepared by adding 0.079% and 0.794% of the ASG fraction fractionated by the above method to the AIN93G diet, and adjusting the weight with corn starch. Table 3 shows the composition of the test feed. The AIN93G diet refers to a standard purified feed using mice and rats published in 1993 by the National Institute of Nutrition (AIN).

[投与・試料採取]
群分けは、一般状態が良好な個体を各群の平均体重に差がないよう無作為に3群(白米飼料群、低ASG飼料群及び高ASG飼料群)に振り分け実施した。飼料は粉末給餌とし、群分け後から、それぞれの被験飼料を105日間自由摂取させた。また、分取したASG画分は、AIN93Gをベースとした7%脂肪食に0.079%及び0.794%を添加して給餌した。なお、ASG画分の影響を比較検討するために、白米飼料で飼育したマウスを対照とした。
[Dosing / Sample collection]
For grouping, individuals with good general condition were randomly assigned to 3 groups (white rice feed group, low ASG feed group and high ASG feed group) so that there was no difference in the average body weight of each group. The feed was powdered and each test feed was ingested freely for 105 days after grouping. The fractionated ASG fraction was fed with 0.079% and 0.794% added to a 7% fat diet based on AIN93G. In order to compare and examine the influence of the ASG fraction, a mouse raised on a white rice diet was used as a control.

[測定]
一般状態の観察は群分け日から投与終了翌日の採血・解剖日までの105日間毎日行い、死亡した個体については記録を行い、生存率を算出した。投与終了翌日には4時間以上絶食を行い、エーテル麻酔下で採血を実施した。採血した血液は血漿を分離し、各種項目血液成分の測定用とした。

The general condition was observed every day for 105 days from the day of grouping to the day of blood collection and dissection on the day after the end of administration, and the dead individuals were recorded and the survival rate was calculated. The day after the administration was completed, the animals were fasted for 4 hours or more, and blood was collected under ether anesthesia. The collected blood was separated from plasma and used for measuring blood components of various items.

〔統計解析〕
各評価項目は、一元配置分散分析後、有意差があった場合には、多重比較検定としてTukey検定を実施した。各群間の有意水準はP<0.05とした。
〔Statistical analysis〕
Each evaluation item was subjected to Tukey test as a multiple comparison test when there was a significant difference after one-way analysis of variance. The significance level between each group was P <0.05.

[測定結果]
白米飼料群では105日間飼育後には、試験開始時に比較して生存率が約6割になっていたのに対して、低ASG飼料、高ASG飼料を摂取していた群では試験期間中に死亡する個体は見られなかった(図1)。
[Measurement result]
The white rice feed group had a survival rate of approximately 60% after 105 days of breeding compared to the start of the test, whereas the group that had consumed the low ASG and high ASG diets died during the test period. No individual was seen (Fig. 1).

〔測定結果〕
屠殺時の血中IGF−1濃度は白米飼料摂取群と比較して、低ASG飼料群、高ASG飼料群では有意に上昇していた
〔Measurement result〕
The blood IGF-1 concentration at the time of slaughter was significantly increased in the low ASG diet group and the high ASG diet group compared to the white rice diet intake group

<動物試験(2)>
順化期間3週間を経た8週齢の雄性老化促進マウス(SAMP−8)を用いて、ASG画分が、老齢マウスの持久力に及ぼす作用機序を検討した。飼料は表3に示す3種類を用いたほかの飼育条件は先に記載した動物試験(1)と同様とした。
[持久力評価試験]
運動量測定試験は、試験終了(屠殺実施)1週間前に実施した。具体的には半径25cmの円筒形の筒の中に25℃の水を水深14cmとなるように満たし、その中でマウスを5分間遊泳させた。マウスの遊泳時間(動時間)を測定することにより運動時間とした。
<Animal test (2)>
Using an 8-week-old male aging-promoted mouse (SAMP-8) after an acclimatization period of 3 weeks, the mechanism of action of the ASG fraction on endurance in old mice was examined. The other breeding conditions using the three types of feed shown in Table 3 were the same as in the animal test (1) described above.
[Endurance evaluation test]
The exercise amount measurement test was performed one week before the end of the test (slaughter). Specifically, 25 ° C. water was filled in a cylindrical tube with a radius of 25 cm so that the water depth was 14 cm, and the mouse was allowed to swim for 5 minutes. The exercise time was determined by measuring the swimming time (movement time) of the mouse.

試験結果はKruskal-Wallis検定を行い、各群間に有意差が認められた場合には多重比較検定としてSteel-Dwass検定を実施した。*<0.05, **<0.01として試験結果を図2に示す。
試験結果は、白米飼料群に比べて、低ASG飼料群及び高ASG飼料群は有意に遊泳時間が長いことが示された。
したがって、強制的な運動環境設定した本試験において、遊泳時間が延びたことは、それぞれの個体の持久力を示しているものである。一般食にあたる白米飼料に比べて、発芽玄米糠から抽出したASG飼料を投与した個体は持久力が向上していることを示していることとなる。
The test results were subjected to the Kruskal-Wallis test. When a significant difference was observed between the groups, the Steel-Dwass test was performed as a multiple comparison test. The test results are shown in FIG. 2 with * <0.05 and ** <0.01.
The test results showed that the swimming time was significantly longer in the low ASG feed group and the high ASG feed group than in the white rice feed group.
Therefore, in this test in which a forced exercise environment is set, the extended swimming time indicates the endurance of each individual. Compared with the white rice feed which is a general meal, the individual | organism | solid which administered the ASG feed extracted from the germinated brown rice bran has shown that the endurance is improving.
