さらに、本発明は、第四に、安全性の高い天然物の中から、サイクリックAMPホスホジエステラーゼ阻害作用を有する物質を見出し、それを有効成分とした脂質代謝改善用組成物を提供することを目的とする。
【0009】
【課題を解決するための手段】
上記目的を達成するため、本発明は、ノブドウ抽出物を有効成分として含有する線維芽細胞増殖用組成物を提供する。
【0011】
本発明の線維芽細胞増殖用組成物において、前記ノブドウ抽出物が、水溶性有機溶媒、含水水溶性有機溶媒又は水を抽出溶媒とした抽出処理により得られたものであることが好ましい。
【0014】
【発明の実施の形態】
以下、本発明について詳細に説明する。
本発明において、「ノブドウ抽出物」には、ノブドウを抽出原料として得られる抽出液、該抽出液の希釈液若しくは濃縮液、該抽出液を乾燥して得られる乾燥物、又はこれらの粗精製物若しくは精製物のいずれもが含まれる。
【0015】
抽出原料として使用するノブドウの部位は特に限定されるものではないが、例えば、地上部を使用することができ、その中でも特に茎部、蔓部及び葉部の1種又は2種以上を使用することが好ましい。
【0016】
抽出原料として使用するノブドウは、採取後ただちに乾燥し粉砕したものが適当である。乾燥は天日で行ってもよいし、通常使用される乾燥機を用いて行ってもよい。また、ヘキサン、ベンゼン等の非極性溶媒によって脱脂等の前処理を施してから抽出原料として使用してもよい。脱脂等の前処理を行うことにより、ノブドウの極性溶媒による抽出処理を効率よく行うことができる。
【0017】
抽出処理の際には、抽出溶媒として極性溶媒を使用することが好ましい。ノブドウに含まれる抗酸化作用、皮膚老化防止作用、抗炎症作用又は脂質代謝改善作用を示す成分は、極性溶媒を抽出溶媒とする抽出処理によって容易に抽出することができる。
【0018】
極性溶媒の具体例としては、水、水溶性有機溶媒等が挙げられ、これらを単独で又は2種以上を組み合わせて用いることができる。これら極性溶媒のうち、水溶性有機溶媒又は含水水溶性有機溶媒を使用することが好ましい。
【0019】
抽出溶媒として使用し得る水には、純水、水道水、井戸水、鉱泉水、鉱水、温泉水、湧水、淡水等の他、これらに各種処理を施したものが含まれる。水に施す処理としては、例えば、精製、加熱、殺菌、滅菌、ろ過、イオン交換、浸透圧の調整、緩衝化等が含まれる。従って、本発明において抽出溶媒として使用し得る水には、精製水、熱水、イオン交換水、生理食塩水、リン酸緩衝液、リン酸緩衝生理食塩水等が含まれる。
【0020】
抽出溶媒として使用し得る水溶性有機溶媒としては、低級脂肪族アルコール、アセトン、テトラヒドロフラン等が挙げられ、低級脂肪族アルコールの具体例としては、メタノール、エタノール、プロパノール、ブタノール等の1価アルコール;1,3−ブチレングリコール、グリセリン、プロピレングリコール、イソプロピレングリコール等の多価アルコール等が挙げられる。
抽出溶媒としては、酢酸エチル、酢酸ブチル、メチルセロソルブ等の中間極性溶媒を使用することもできる。
【0021】
2種以上の極性溶媒の混合液を抽出溶媒として使用する場合、その混合比は適宜調整することができる。例えば、含水水溶性有機溶媒を使用する場合、一価アルコール、多価アルコール、アセトン、テトラヒドロフラン等の含有量が10重量%以上であることが好ましい。
【0022】
抽出処理は、ノブドウに含まれる可溶性成分を抽出溶媒に溶出させ得る限り特に限定されず、常法に従って行うことができる。例えば、抽出原料の5〜15倍量(重量比)の抽出溶媒にノブドウを浸漬し、常温又は還流加熱下で可溶性成分を溶出させた後、ろ過して抽出残渣を除くことにより抽出液を得ることができる。得られた抽出液は、該抽出液の希釈液若しくは濃縮液、該抽出液の乾燥物、又はこれらの粗精製物若しくは精製物を得るために、常法に従って希釈、濃縮、乾燥、精製等の処理を施してもよい。精製は、例えば、活性炭処理、吸着樹脂処理、イオン交換樹脂処理、液−液向流分配処理等によって行うことができる。得られた抽出液はそのままでも抗酸化組成物、皮膚老化防止用組成物、抗炎症組成物又は脂質代謝改善用組成物の有効成分として使用することができるが、濃縮液又は乾燥物としたものの方が利用しやすい。
【0023】
ノブドウ抽出物は、活性酸素消去作用及び/又はラジカル消去作用に基づいて抗酸化作用を発揮することができる。ここで、「活性酸素」には、スーパーオキサイド、過酸化水素、ヒドロキシラジカル、一重項酸素等が含まれる。また、「ラジカル」とは、不対電子を1つまたはそれ以上有する分子または原子を意味し、スーパーオキサイド、ヒドロキシラジカル、DPPH等が含まれる。
【0024】
ノブドウ抽出物は、抗酸化作用を発揮することができるので、抗酸化組成物の有効成分として使用することができる。なお、ノブドウ抽出物は、活性酸素消去作用又はラジカル消去作用を有しているので、活性酸素消去用組成物又はラジカル消去用組成物の有効成分として使用することもできる。
【0025】
本発明の抗酸化組成物は、体内における活性酸素濃度の上昇(例えば、体内における活性酸素過剰産生による活性酸素濃度の上昇、老人等におけるスーパーオキサイドジスムターゼ(SOD)作用低下による活性酸素濃度の上昇)に起因する疾患、例えば、関節リウマチ、心筋梗塞、糖尿病、腎炎、肩こり、冷え性等を効果的に予防及び/又は改善することができる。また、本発明の抗酸化組成物は、薬剤、飲食品、化粧料等に配合される油脂類等、活性酸素の働きにより酸化又は劣化する成分の変質を効果的に防止することができる。
【0026】
皮膚は紫外線等の環境因子の影響を直接受けるため活性酸素が発生しやすい器官であるから、何らかの理由により生体の抗酸化作用が十分に働かないと活性酸素濃度が上昇し、それに起因してメラニンの異常産生、シワ、たるみ、肌荒れ等の皮膚老化現象が生じる。また、加齢により皮膚の細胞増殖能が鈍化すると細胞の更新が行われにくくなるとともに、細胞により生産されるコラーゲン等の細胞間成分の供給も不十分となり、それに起因してシワ、たるみ、くすみ等の皮膚老化現象が生じる。さらに、皮膚の弾性に関与するエラスチンが加水分解酵素であるエラスターゼにより分解されると、皮膚の弾力が減少し、シワ、たるみ等の皮膚老化現象が生じる。したがって、ノブドウ抽出物は、活性酸素消去作用、ラジカル消去作用、線維芽細胞増殖作用及びエラスターゼ阻害作用からなる群より選ばれる1種又は2種以上の作用に基づいて皮膚老化防止作用を発揮することができる。
【0027】
ノブドウ抽出物は、皮膚老化防止作用を発揮することができるので、皮膚老化防止用組成物の有効成分として使用することができる。なお、ノブドウ抽出物は、線維芽細胞増殖作用又はエラスターゼ阻害作用を有しているので、線維芽細胞増殖用組成物又はエラスターゼ阻害用組成物の有効成分として利用することもできる。
本発明の皮膚老化防止用組成物は、皮膚の弾力低下、シワ、たるみ、肌荒れ等の皮膚老化現象を効果的に予防及び/又は改善することができる。
【0028】
ヒアルロニダーゼは生体内の様々な組織に通常不活性な状態で存在するが活性化すると毛細血管の透過性を亢進すること、種々の炎症においてヒアルロニダーゼ活性が上昇すること、ヒアルロニダーゼを用いて実験的に急性炎症モデルを作製できること等の事実により、ヒアルロニダーゼが炎症反応に関与することが確認されており、ヒアルロニダーゼは起炎酵素とも呼ばれている。また、サイクリックAMPホスホジエステラーゼによりサイクリックAMPが分解され、サイクリックAMP濃度が低下すると血小板凝集が生じ、血小板凝集はアラキドン酸カスケードのホスホリパーゼA2の活性化を招き、それにより放出されたロイコトリエンB4やプロスタグランジンE2等が炎症反応を引き起こす。したがって、ノブドウ抽出物は、ヒアルロニダーゼ阻害作用及び/又はサイクリックAMPホスホジエステラーゼ阻害作用に基づいて抗炎症作用を発揮することができる。
【0029】
ノブドウ抽出物は、抗炎症作用を発揮することができるので、抗炎症組成物の有効成分として使用することができる。なお、ノブドウ抽出物は、ヒアルロニダーゼ阻害作用又はサイクリックAMPホスホジエステラーゼ阻害作用を有しているので、ヒアルロニダーゼ阻害用組成物又はサイクリックAMPホスホジエステラーゼ阻害用組成物の有効成分として利用することもできる。
本発明の抗炎症組成物は、炎症性の疾患、例えば、接触性皮膚炎(かぶれ)、乾癬、尋常性天疱瘡等を効果的に予防及び/又は改善することができる。
【0030】
脂質の代謝促進に関与しているサイクリックAMPが、サイクリックAMPホスホジエステラーゼによって分解されると、脂質の代謝が抑制され、体脂肪の過剰蓄積等が生じる。したがって、ノブドウ抽出物は、サイクリックAMPホスホジエステラーゼ阻害作用に基づいて脂質代謝改善作用を発揮することができる。
すなわち、ノブドウ抽出物は、サイクリックAMPホスホジエステラーゼ活性を阻害し、細胞内サイクリックAMP濃度を上昇させ、脂質の代謝を活発化させることにより、脂質代謝改善作用を発揮することができる。
ノブドウ抽出物は、脂質代謝改善作用を発揮することができるので、脂質代謝改善用組成物の有効成分として使用することができる。
本発明の脂質代謝改善用組成物は、脂質代謝を改善することにより肥満を予防及び/又は改善することができる。
【0031】
本発明の各組成物において、「有効成分」とは、抗酸化作用、皮膚老化防止作用、抗炎症作用又は脂質代謝改善作用を有する成分を意味し、ノブドウ抽出物が本発明の各組成物の主成分である必要はなく、また、本発明の各組成物にはノブドウ抽出物以外に抗酸化作用、皮膚老化防止作用、抗炎症作用又は脂質代謝改善作用を有する成分が含まれていてもよい。

【0054】
エラスターゼ阻害率(%)={1−(A−B)/(C−D)}×100
なお、式中、「A」は酵素添加・試料溶液添加時の吸光度、「B」は酵素無添加・試料溶液添加時の吸光度、「C」は酵素添加・試料溶液無添加時の吸光度、「D」は酵素無添加・試料溶液無添加時の吸光度を表す。

[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a composition for proliferating fibroblasts, which contains a grape extract as an active ingredient.
[0011]
In the composition for proliferating fibroblasts of the present invention, it is preferable that the grape extract is obtained by an extraction treatment using a water-soluble organic solvent, a water-containing water-soluble organic solvent, or water as an extraction solvent.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
In the present invention, the “no grape extract” refers to an extract obtained using no grape as an extraction raw material, a diluted or concentrated solution of the extract, a dried product obtained by drying the extract, or a crudely purified product thereof. Alternatively, any purified product is included.
[0015]
The part of wild grape used as the extraction raw material is not particularly limited. For example, the above-ground part can be used, and among them, one or more of stem part, vine part and leaf part are used. It is preferable.
[0016]
The grapes used as the raw material for extraction are suitably dried and pulverized immediately after collection. Drying may be performed in the sun or using a commonly used dryer. Moreover, after performing pre-processing, such as degreasing, with nonpolar solvents, such as hexane and benzene, you may use as an extraction raw material. By performing a pretreatment such as degreasing, the extraction process with the polar solvent of No grape can be efficiently performed.
[0017]
In the extraction process, it is preferable to use a polar solvent as the extraction solvent. Ingredients showing antioxidative action, skin aging preventive action, anti-inflammatory action or lipid metabolism improving action contained in grapevine can be easily extracted by extraction treatment using a polar solvent as an extraction solvent.
[0018]
Specific examples of the polar solvent include water and water-soluble organic solvents, and these can be used alone or in combination of two or more. Of these polar solvents, it is preferable to use a water-soluble organic solvent or a water-containing water-soluble organic solvent.
[0019]
Water that can be used as the extraction solvent includes pure water, tap water, well water, mineral spring water, mineral water, hot spring water, spring water, fresh water, and the like, as well as those subjected to various treatments. Examples of the treatment applied to water include purification, heating, sterilization, sterilization, filtration, ion exchange, adjustment of osmotic pressure, buffering, and the like. Therefore, the water that can be used as the extraction solvent in the present invention includes purified water, hot water, ion-exchanged water, physiological saline, phosphate buffer, phosphate buffered saline, and the like.
[0020]
Examples of water-soluble organic solvents that can be used as the extraction solvent include lower aliphatic alcohols, acetone, tetrahydrofuran, and the like. Specific examples of lower aliphatic alcohols include monohydric alcohols such as methanol, ethanol, propanol, and butanol; 1 , 3-butylene glycol, glycerin, propylene glycol, isopropylene glycol, and other polyhydric alcohols.
As the extraction solvent, an intermediate polar solvent such as ethyl acetate, butyl acetate or methyl cellosolve can be used.
[0021]
When using the liquid mixture of 2 or more types of polar solvents as an extraction solvent, the mixing ratio can be adjusted suitably. For example, when a water-containing water-soluble organic solvent is used, the content of monohydric alcohol, polyhydric alcohol, acetone, tetrahydrofuran or the like is preferably 10% by weight or more.
[0022]
The extraction treatment is not particularly limited as long as the soluble component contained in wild grape can be eluted in the extraction solvent, and can be performed according to a conventional method. For example, vine grapes are immersed in an extraction solvent 5 to 15 times the weight of the extraction raw material (weight ratio), and soluble components are eluted at room temperature or under reflux heating, followed by filtration to remove the extraction residue to obtain an extract. be able to. The obtained extract is diluted, concentrated, dried, purified, etc. according to a conventional method in order to obtain a diluted or concentrated solution of the extract, a dried product of the extract, or a crude purified product or a purified product thereof. Processing may be performed. Purification can be performed by, for example, activated carbon treatment, adsorption resin treatment, ion exchange resin treatment, liquid-liquid countercurrent distribution treatment, or the like. The obtained extract can be used as an active ingredient of an antioxidant composition, a composition for preventing skin aging, an anti-inflammatory composition, or a composition for improving lipid metabolism as it is, but it can be used as a concentrated solution or a dried product. It is easier to use.
[0023]
The grapevine extract can exert an antioxidant action based on the active oxygen scavenging action and / or the radical scavenging action. Here, “active oxygen” includes superoxide, hydrogen peroxide, hydroxy radical, singlet oxygen and the like. “Radical” means a molecule or atom having one or more unpaired electrons, and includes superoxide, hydroxy radical, DPPH and the like.
[0024]
Since the grape extract can exert an antioxidant action, it can be used as an active ingredient of an antioxidant composition. The grapevine extract has an active oxygen scavenging action or a radical scavenging action, and can therefore be used as an active ingredient of the active oxygen scavenging composition or radical scavenging composition.
[0025]
The antioxidant composition of the present invention has increased active oxygen concentration in the body (for example, increased active oxygen concentration due to excessive production of active oxygen in the body, increased active oxygen concentration due to decreased superoxide dismutase (SOD) action in the elderly). It is possible to effectively prevent and / or ameliorate diseases caused by the disease, such as rheumatoid arthritis, myocardial infarction, diabetes, nephritis, stiff shoulders, coldness and the like. Moreover, the antioxidant composition of the present invention can effectively prevent alteration of components that are oxidized or deteriorated by the action of active oxygen, such as oils and fats blended in drugs, foods and drinks, cosmetics and the like.
[0026]
Since the skin is directly affected by environmental factors such as ultraviolet rays, it is an organ that is prone to generate active oxygen. Therefore, for some reason, the active oxygen concentration rises if the body's antioxidant action does not work sufficiently, resulting in melanin. Skin aging phenomena such as abnormal production, wrinkles, sagging, and rough skin occur. In addition, when the cell growth ability of the skin slows down due to aging, renewal of cells becomes difficult, and supply of intercellular components such as collagen produced by cells becomes insufficient, resulting in wrinkles, sagging, dullness. Skin aging phenomenon occurs. Furthermore, when elastin involved in skin elasticity is decomposed by elastase, which is a hydrolase, the elasticity of the skin decreases, and skin aging phenomena such as wrinkles and sagging occur. Therefore, the grapevine extract exhibits a skin aging preventing action based on one or more actions selected from the group consisting of an active oxygen scavenging action, a radical scavenging action, a fibroblast proliferation action and an elastase inhibitory action. Can do.
[0027]
Since the grape extract can exert an anti-skin aging effect, it can be used as an active ingredient in a composition for preventing skin aging. In addition, since a grapevine extract has a fibroblast proliferation action or an elastase inhibitory action, it can also be utilized as an active ingredient of the composition for fibroblast proliferation or the composition for elastase inhibition.
The composition for preventing skin aging according to the present invention can effectively prevent and / or improve skin aging phenomena such as reduced skin elasticity, wrinkles, sagging and rough skin.
[0028]
Hyaluronidase is normally inactive in various tissues in the body, but when activated, it increases the permeability of capillaries, increases hyaluronidase activity in various inflammations, and is experimentally acute with hyaluronidase. It has been confirmed that hyaluronidase is involved in the inflammatory reaction due to the fact that an inflammation model can be prepared, and hyaluronidase is also called a pro-inflammatory enzyme. In addition, cyclic AMP is degraded by cyclic AMP phosphodiesterase, and when the cyclic AMP concentration is lowered, platelet aggregation occurs, and the platelet aggregation leads to activation of phospholipase A2 of the arachidonic acid cascade, and thus released leukotriene B4 and prostas. Grungein E2 etc. cause an inflammatory reaction. Therefore, the grapevine extract can exert an anti-inflammatory action based on a hyaluronidase inhibitory action and / or a cyclic AMP phosphodiesterase inhibitory action.
[0029]
Since grapevine extract can exert an anti-inflammatory action, it can be used as an active ingredient of an anti-inflammatory composition. In addition, since the grapevine extract has a hyaluronidase inhibitory action or a cyclic AMP phosphodiesterase inhibitory action, it can also be used as an active ingredient of a hyaluronidase inhibitory composition or a cyclic AMP phosphodiesterase inhibitory composition.
The anti-inflammatory composition of the present invention can effectively prevent and / or improve inflammatory diseases such as contact dermatitis (rash), psoriasis, pemphigus vulgaris and the like.
[0030]
When cyclic AMP involved in the promotion of lipid metabolism is degraded by cyclic AMP phosphodiesterase, lipid metabolism is suppressed, resulting in excessive accumulation of body fat. Therefore, the grape extract can exert a lipid metabolism improving action based on the cyclic AMP phosphodiesterase inhibitory action.
That is, the grapevine extract can exert a lipid metabolism improving action by inhibiting cyclic AMP phosphodiesterase activity, increasing intracellular cyclic AMP concentration, and activating lipid metabolism.
Since the grape extract can exert an action of improving lipid metabolism, it can be used as an active ingredient of a composition for improving lipid metabolism.
The composition for improving lipid metabolism of the present invention can prevent and / or improve obesity by improving lipid metabolism.
[0031]
In each composition of the present invention, the “active ingredient” means a component having an antioxidant action, an anti-skin aging action, an anti-inflammatory action or a lipid metabolism improving action, and the grape extract is used in each composition of the present invention. It is not necessary to be a main component, and each composition of the present invention may contain an ingredient having an antioxidative action, an anti-skin aging action, an anti-inflammatory action or a lipid metabolism improving action in addition to the grape extract. .
[0032]
The form of each composition of the present invention is not particularly limited as long as the intended effect can be exhibited. Specific examples thereof include a pharmaceutical composition, a food and drink composition, a feed composition, and a cosmetic composition. Thing etc. are mentioned. Components other than the grape extract in each composition of the present invention can be appropriately selected according to the form of the composition.
[0033]

Thereafter, the absorbance at 520 nm was measured. As a control test, the same operation was performed using the solvent instead of the sample solution, and the absorbance at 520 nm was measured. As a blank test, the absorbance at 520 nm was immediately measured after adding 3 mL of the methanol sample solution.
Based on each measured absorbance, the radical scavenging rate was calculated by the following formula.
[0050]
Radical scavenging rate (%) = [1- (BC) / A] × 100
In the formula, “A” represents the absorbance in the control test, “B” represents the absorbance when the sample solution was added, and “C” represents the absorbance in the blank test.
The above-mentioned erasure rate was measured while changing the sample concentration of the sample solution stepwise, and the concentration of the sample solution at which the DPPH radical erasure rate was 50% was determined by interpolation. IC 50 (Radical 50% elimination concentration) (μg / mL) is shown in Table 3.

[Test Example 4] Elastase inhibitory action test
The extract obtained in Production Example 1 was examined for elastase inhibitory action. The test method is as follows.
Prepare a 96-well microplate. 50 μL of sample solution (solvent: DMSO + water), 25 μL of substrate solution (2 mM N-methoxysuccinyl-Ala-Ala-Pro-Val-p-nitroanilide) and elastase solution (human preferred) Neutrophil-derived elastase; 6 μg / mL) was added. After reacting at 25 ° C. for 30 minutes, the reaction solution was collected and the absorbance at 415 nm was measured. Enzymatic reaction and absorbance measurement similar to the above were performed by adding only the solvent equivalent to the sample solution instead of the sample solution. Further, in each case, the same operation and measurement were performed without adding the elastase solution. From the measurement results, the elastase inhibition rate was calculated by the following formula.
[0054]
Elastase inhibition rate (%) = {1− (A−B) / (C−D)} × 100
In the formula, “A” is the absorbance when the enzyme is added and the sample solution is added, “B” is the absorbance when the enzyme is not added and the sample solution is added, “C” is the absorbance when the enzyme is added and the sample solution is not added, “ “D” represents the absorbance when no enzyme was added and no sample solution was added.
Measure the above inhibition rate by decreasing the sample concentration step by step, and the sample concentration IC at which the inhibition rate becomes 50% 50 (Μg / mL) was determined by interpolation. IC 50 (Elastase 50% inhibitory concentration) (μg / mL) is shown in Table 4.

[Test Example 5] Fibroblast proliferation test
The extract obtained in Production Example 1 was examined for NB1RBG cell proliferation action. The test method was performed according to the MTT method (J. Immunol. Method, 93, 157, 1986).
25cm 2 Human normal neonatal skin fibroblasts (NBIRGB) 1 × 10 in 10 v / v% FBS-containing medium (α-MEM medium: GIBCO BLR, product pH 7.2) 6 Seeded, 37 ° C, 5% CO 2 Cultured for 4 days under -95% air. Cells were then collected by trypsinization and centrifugation. Cells obtained as a precipitate were suspended in a medium containing 5 v / v% FBS (α-MEM medium: GIBCO BLR, pH 7.2), and 7 × 10 6 per well of a 96-well plate. 3 Dispense / 100 μL. After culturing for 24 hours, 100 μL per well of 5 v / v% FBS-containing medium in which the sample was dissolved was added, and the mixture was incubated at 37 ° C., 5% CO 2 -Cultured for 3 days under -95% air. After the culture, the medium was removed by 100 μL per well, and MTT reagent (3- (4,5-dimethyl1-2-thiazolyl) -2,5-diphenyl-2H tetrazolium bromide, 5 mg / mL PBS (−) solution) 20 μL Was added and incubated for 4.5 hours (reactive oxygen from mitochondria in the grown cells reacted with the MTT reagent, and the color of the reagent that was yellow turns blue-yellow with an absorption peak at 570 nm). Thereafter, 100 μL of 10 wt% sodium dodecyl sulfate-0.02 mol / L sulfuric acid solution was dispensed into each well and incubated for 18 hours. After completion of the incubation, the absorbance at 570 nm was measured using a microplate reader. Separately, the absorbance was measured by changing the presence / absence of the sample and the presence / absence of cells. In addition, each absorbance measurement value was corrected by subtracting the absorbance measured at 650 nm at the same time to correct the influence of turbidity caused by the grown cells. From each corrected absorbance, the cell growth promotion rate was determined by the following formula.
[0058]
Cell growth promotion rate (%) = {(AC)-(BD)} / (BD) × 100
In the formula, “A” is the absorbance when the sample is added, “B” is the absorbance when the sample is not added, “C” is the absorbance when the sample is added and no cell is added, and “D” is the sample added and no cell is added. It represents the absorbance at the time of addition.
The elimination rate was measured by decreasing the sample concentration stepwise, and the sample concentration (μg / mL) at which the fibroblast proliferation rate was 50% was determined by interpolation. The results are shown in Table 5.

After adding 0.5 mL of potassium hyaluronate buffer and incubating at 37 ° C. for 40 minutes, 0.2 mL of 0.4N sodium hydroxide was added and ice-cooled to stop the reaction. Next, 0.2 mL of 0.8 M boric acid solution (pH 9.1) was added, heated in a boiling bath for 3 minutes, and immediately cooled on ice for 20 minutes. Add 6.0 mL of P-DABA reagent (10 g of p-dimethylaminobenzaldehyde dissolved in 12.5 mL of 10N hydrochloric acid and 87.5 mL of acetic acid and dilute 10-fold with acetic acid) and incubate at 37 ° C. for 20 minutes As a result, N-acetylglucosamine released by the enzyme reaction was colored and the absorbance at a wavelength of 585 nm was measured. The same operation and absorbance measurement were performed without adding the enzyme. Furthermore, the same measurement was performed when distilled water was added without adding the sample solution, and the hyaluronidase inhibition rate was determined by the following equation.
[0062]
Hyaluronidase inhibition rate (%) = {1− (A−B) / (C−D)} × 100
In the formula, “A” is the absorbance when the enzyme is added and the sample solution is added, “B” is the absorbance when the enzyme is not added and the sample solution is added, “C” is the absorbance when the enzyme is added and the sample solution is not added, “ “D” represents the absorbance when no enzyme was added and no sample solution was added.

Next, 0.05 mL of a cyclic AMP solution (0.5 mg / mL) was added and reacted at 37 ° C. for 60 minutes. After the reaction, the reaction was stopped by boiling for 3 minutes in boiling water, centrifuged at 4 ° C., and the reaction substrate (cyclic AMP) in the supernatant was quantified by high performance liquid chromatography.
[0066]
