JP 2004-73186 A

本発明は、かかる事情に鑑み、魚類の卵巣膜から抽出された成分の新たな用途を提供することを目的とする。   In view of such circumstances, an object of the present invention is to provide a new use of a component extracted from the ovarian membrane of fish.

かかる目的を達成するために、本発明のIGF−1値上昇剤は、鮭の卵巣膜をタンパク分解酵素で処理することにより抽出された成分を含むことを特徴とする。 In order to achieve such an object, the agent for raising IGF-1 level of the present invention is characterized by containing a component extracted by treating the ovarian membrane of sputum with a proteolytic enzyme .

生体においては、成年期を過ぎると加齢に伴って新陳代謝が衰える、無気力になる、肌の肌理が荒くなる、つや、はりが無くなる、シミ、ソバカスが多くなる等の諸症状が現れてくる。前記加齢に伴う諸症状は、IGF−1値の低下として把握され、通常は、一旦下降したIGF−1値が再度上昇することは無いとされている。   In the living body, after the adulthood, various symptoms appear, such as deterioration of metabolism with aging, becoming lethargic, rough skin texture, no gloss, no stickiness, more spots and freckles. The various symptoms associated with the aging are grasped as a decrease in IGF-1 value, and it is usually said that the IGF-1 value once decreased does not increase again.

ところが、本発明のIGF−1値上昇剤によれば、IGF−1値を再び上昇させることができ、前記加齢に伴う諸症状を緩和、改善することができる。 However, according to the IGF-1 level increasing agent of the present invention, the IGF-1 level can be increased again, and various symptoms associated with the aging can be alleviated and improved.

次に、添付の図面を参照しながら本発明の実施の形態についてさらに詳しく説明する。図1は本実施形態のIGF−1値上昇剤を摂取した場合とプラセボ(偽薬)を摂取した場合とのIGF−1値の経時的変化を示すグラフ、図2は本実施形態のIGF−1値上昇剤を摂取した場合とプラセボ(偽薬)を摂取した場合とのIGF−1値の変化量を示すグラフ、図3は本実施形態のIGF−1値上昇剤を8週間摂取した後の体調と摂取中止から2週間後の体調との比較を示すグラフである。 Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 is a graph showing changes over time in IGF-1 values when an IGF-1 level-increasing agent of this embodiment is ingested and when a placebo (placebo) is ingested, and FIG. 2 is a graph showing IGF-1 of this embodiment. FIG. 3 is a graph showing the amount of change in IGF-1 value when taking a value increasing agent and when taking a placebo (placebo), FIG. 3 shows the physical condition after ingesting the IGF-1 increasing agent of this embodiment for 8 weeks It is a graph which shows the comparison with the physical condition 2 weeks after an intake stop.

本実施形態のIGF−1値上昇剤は、鮭の卵巣膜から抽出された成分(以下、卵巣膜抽出成分と略記する)を含む。前記卵巣膜抽出成分は、鮭の卵巣膜を酵素処理してタンパク質を抽出した溶液を、濾過し、得られた濾液を乾燥させる方法等により得ることができる。 The IGF-1 level increasing agent of this embodiment includes a component extracted from the ovary membrane of rabbit (hereinafter abbreviated as an ovarian membrane extraction component). The ovarian membrane extract component can be obtained by, for example, a method of filtering a solution obtained by performing enzyme treatment on the ovary membrane of salmon and drying the obtained filtrate.

前記方法では、具体的には、まず、鮭の卵巣膜を原料とし、該卵巣膜に対して水を卵巣膜:水=1:1〜1:3の重量比で加えて撹拌、混合し、さらにタンパク分解酵素を卵巣膜の全量に対して1〜3重量%の範囲で添加し、45〜55℃の温度で30分間〜5時間、好ましくは2時間加熱する。このようにすると、前記卵巣膜の成分のうち、前記タンパク分解酵素で分解された成分が水中に溶出し、該成分の水溶液が得られる。   Specifically, in the method, first, the ovarian membrane of the pupa is used as a raw material, and water is added to the ovarian membrane in a weight ratio of ovarian membrane: water = 1: 1 to 1: 3, and the mixture is stirred and mixed. Furthermore, a proteolytic enzyme is added in the range of 1 to 3% by weight with respect to the total amount of the ovarian membrane, and heated at a temperature of 45 to 55 ° C. for 30 minutes to 5 hours, preferably 2 hours. If it does in this way, the component decomposed | disassembled with the said proteolytic enzyme will elute in water among the components of the said ovary membrane, and the aqueous solution of this component will be obtained.

次に、前記水溶液に含まれている前記タンパク分解酵素を失活する。前記失活は、例えば、前記水溶液を90℃の温度で5分間加熱することにより行うことができる。   Next, the proteolytic enzyme contained in the aqueous solution is inactivated. The deactivation can be performed, for example, by heating the aqueous solution at a temperature of 90 ° C. for 5 minutes.

次に、前記水溶液を30メッシュ程度の金網で簡易濾過し、未分解の卵巣膜等の粗大物を除去する。そして、得られた濾液に活性炭を添加して、該濾液の脱臭、脱色、脱脂を行う。前記濾液の脱臭、脱色、脱脂は、前記原料としての卵巣膜の全量に対して2〜4重量%の範囲の活性炭を該濾液に添加し、例えば60℃の温度で30分間加熱することにより行うことができる。   Next, the aqueous solution is simply filtered through a wire mesh of about 30 mesh to remove coarse materials such as undecomposed ovarian membranes. Then, activated carbon is added to the obtained filtrate to deodorize, decolorize, and degrease the filtrate. The deodorization, decolorization, and degreasing of the filtrate is performed by adding activated carbon in the range of 2 to 4% by weight to the total amount of the ovarian membrane as the raw material and heating the filtrate at a temperature of 60 ° C. for 30 minutes, for example. be able to.

前記活性炭による脱臭、脱色、脱脂処理後、前記濾液を例えばフィルタープレスにより濾過し、得られた濾液を、減圧下、例えば60℃の温度で濃縮した後、例えば80℃の温度に10分間維持して滅菌する。そして、滅菌後の前記濾液をスプレードライにて乾燥させることにより、前記卵巣膜抽出成分を得ることができる。前記卵巣膜抽出成分は、アミノ酸、ペプチド、ビタミン、ミネラル、糖類、酵素、核酸及びその代謝物、各種成長因子、サイトカイン等を含んでいる。   After the deodorization, decolorization, and degreasing treatment with the activated carbon, the filtrate is filtered by, for example, a filter press, and the obtained filtrate is concentrated at a temperature of 60 ° C. under reduced pressure, for example, and then maintained at a temperature of 80 ° C. for 10 minutes, for example. And sterilize. Then, the ovarian membrane extract component can be obtained by drying the sterilized filtrate by spray drying. The ovarian membrane extract component contains amino acids, peptides, vitamins, minerals, sugars, enzymes, nucleic acids and their metabolites, various growth factors, cytokines, and the like.

本実施形態のIGF−1値上昇剤は、前記卵巣膜抽出成分を、例えば錠剤等の形に製剤したものであり、例えば健康食品等の食品として摂取することにより、加齢により低下したIGF−1値を再び上昇させることができ、前記加齢に伴う諸症状を緩和、改善することができる。 The IGF-1 level increasing agent of the present embodiment is prepared by, for example, formulating the ovarian membrane extract component in the form of a tablet or the like. 1 value can be raised again, and various symptoms accompanying the aging can be alleviated and improved.

次に、本発明の実施例と比較例とを示す。   Next, examples of the present invention and comparative examples will be described.

本実施例では、まず、鮭の卵巣膜抽出成分を錠剤の形に製剤して、IGF−1値上昇剤を製造した。前記錠剤は、前記卵巣膜抽出物245mg、賦形剤(ラブリワックス(登録商標))5mgからなり、8mmの直径を備えている。 In this example, first, an ovarian membrane extract component of salmon was formulated in the form of a tablet to produce an IGF-1 increasing agent . The tablet consists of 245 mg of the ovarian membrane extract and 5 mg of excipient (Loveli wax (registered trademark)) and has a diameter of 8 mm.

次に、38〜42歳の健康な女性モニター10名に、前記錠剤を健康食品として1日当たり4錠、8週間に亘って摂取させた。尚、各モニターは、1ヶ月前からサプリメント、薬品(漢方薬を含む)の摂取を行っていない。   Next, 10 healthy female monitors aged 38 to 42 years old took 4 tablets per day for 8 weeks as a health food. Each monitor has not taken supplements or medicines (including herbal medicines) since one month ago.

そして、摂取開始前、摂取開始4週間目、摂取開始8週間目に、血液検査を行い、IGF−1値を測定した。前記モニター10人のIGF−1値の平均値を図1に、摂取開始から4週間目まで、摂取開始から8週間目までのIGF−1値の平均値の変化量を図2に、それぞれ示す。尚、図1中、摂取開始前を「0週」、摂取開始4週間目を「4週」、摂取開始8週間目を「8週」と記載し、図2中、摂取開始から4週間目までを「0−4週」、摂取開始から8週間目までを「0−8週」と記載する。   And before the start of ingestion, 4 weeks after the start of ingestion and 8 weeks after the start of ingestion, a blood test was performed to measure the IGF-1 value. The average value of IGF-1 values of the 10 monitors is shown in FIG. 1, and the amount of change in the average value of IGF-1 values from the start of intake to the 4th week and from the start of intake to the 8th week is shown in FIG. . In FIG. 1, “0 week” is shown before the start of ingestion, “4 weeks” is the 4th week of ingestion, and “8 weeks” is the 8th week of ingestion. “0-4 weeks” and “8-8 weeks” from the start of intake are described.

また、各モニターの自己申告による体調について、摂取開始8週間目と、摂取中止から2週間後との状態を比較した。結果を図3に示す。
〔比較例〕
本比較例では、まず、前記実施例のIGF−1値上昇剤に代えて、コーンスターチ125mg、乳糖125mgからなるプラセボ(偽薬)を、直径8mmの錠剤の形に製剤した。
次に、前記実施例とは異なる38〜42歳の健康な女性モニター10名に、前記偽薬のカプセル剤を1日当たり4錠、8週間に亘って投与した。尚、各モニターは、1ヶ月前からサプリメント、薬品(漢方薬を含む)の摂取を行っていない。
Moreover, regarding the physical condition by self-report of each monitor, the state of the 8th week from the start of intake and the state after 2 weeks from the stop of intake were compared. The results are shown in FIG.
[Comparative Example]
In this comparative example, first, a placebo (placebo) consisting of 125 mg of corn starch and 125 mg of lactose was formulated in the form of a tablet with a diameter of 8 mm instead of the IGF-1 level increasing agent of the above example.
Next, the placebo capsules were administered 4 times a day for 8 weeks to 10 healthy female monitors aged 38 to 42 years different from the Examples. Each monitor has not taken supplements or medicines (including herbal medicines) since one month ago.

次に、前記実施例とは異なる38〜42歳の健康な女性モニター10名に、前記偽薬のカプセル剤を1日当たり4錠、8週間に亘って投与した。尚、各モニターは、1ヶ月前からサプリメント、薬品(漢方薬を含む)の摂取を行っていない。   Next, the placebo capsules were administered 4 times a day for 8 weeks to 10 healthy female monitors aged 38 to 42 years different from the Examples. Each monitor has not taken supplements or medicines (including herbal medicines) since one month ago.

そして、前記実施例と全く同一にして、IGF−1値を測定した。前記モニター10人のIGF−1値の平均値を図1に、摂取開始4週間目、摂取開始8週間目のIGF−1値の平均値の変化量を図2に、それぞれ示す。   Then, the IGF-1 value was measured in exactly the same manner as in the above example. The average value of the IGF-1 values of the 10 monitors is shown in FIG. 1, and the amount of change in the average value of the IGF-1 values at the 4th week of ingestion and the 8th week of ingestion is shown in FIG.

図1から、本実施形態のIGF−1値上昇剤(実施例)によれば、摂取開始4週間目には摂取開始前に比較してIGF−1値が増加しており、摂取開始8週間目には摂取開始4週間目よりもさらに増加しており、単調に増加していることが明らかである。これに対して、プラセボ(比較例)によれば、摂取開始8週間目には摂取開始前に比較してIGF−1値が増加しているものの、摂取開始4週間目には摂取開始前に比較して一旦IGF−1値が減少しており、単調な増加ではないことが明らかである。 From FIG. 1, according to the IGF-1 level-increasing agent (Example) of the present embodiment, the IGF-1 value increased in the 4th week after ingestion compared to before the start of ingestion, and 8 weeks after the start of ingestion. In the eyes, it is further increased than the fourth week after ingestion, and it is apparent that the number is increasing monotonously. On the other hand, according to the placebo (comparative example), the IGF-1 value increased in the 8th week after ingestion compared to before the start of ingestion, but before the start of ingestion in the 4th week after ingestion. In comparison, it is clear that the IGF-1 value has once decreased and is not a monotonous increase.

また、図2から、本実施形態のIGF−1値上昇剤によれば、IGF−1値の増加量がプラセボよりも大きいことが明らかである。 Moreover, it is clear from FIG. 2 that the amount of increase in the IGF-1 value is greater than that of the placebo according to the IGF-1 value increasing agent of the present embodiment.

さらに、図3から、本実施形態のIGF−1値上昇剤を摂取開始後、8週間目の体調の方が、摂取中止から2週間後の体調よりも優れていることが明らかである。これは、本実施形態のIGF−1値上昇剤を摂取開始後、8週間目には、IGF−1値の増加により体調が好転していたものが、摂取中止に伴いIGF−1値増加の効果が低減したものと考えられる。 Furthermore, it is clear from FIG. 3 that the physical condition at 8 weeks after the start of ingestion of the IGF-1 level-increasing agent of this embodiment is superior to the physical condition at 2 weeks after ingestion. This is because in 8 weeks after the start of ingestion of the IGF-1 level increasing agent of this embodiment, the physical condition improved due to the increase in IGF-1 value, but the increase in IGF-1 value with the discontinuation of intake It is thought that the effect was reduced.
