Hereinafter, the various medicinal effects will be described with examples.

実施例1(抗骨粗鬆症効果)
骨粗鬆症改善効果試験
SD系ラット(22週齢)メスの卵巣を外科的に取り除き、骨粗鬆症のモデルラットを作成した。卵巣摘出ラットを7匹ずつ6群に分け、35日間の試験期間中、1日置きに(計17回)、HMBが30mg/kgとなるように、生理食塩水溶解した液体を経口投与した。飼料はオリエンタル酵母株式会社のマウス・ラット・ハムスター用固形飼料CRF−1を用い、給餌および給水方法は自由摂取とした。試験期間中、各群間で、餌の摂取量に差は認められなかった。試験開始後35日目にラットの体重を測定した後、大腿骨を取り出した。大腿骨は、接着組織および筋肉を取り除いて分析に使用した。大腿骨の体積を測定した後、エタノールで3回洗浄し、次にアセトンで3回洗浄したのち、一晩乾燥し、その後、重量を測定して大腿骨の乾燥重量を求めた。体積および乾燥重量から、骨密度(乾燥重量g/体積mm3 )を測定した。なお対照実験として、HMBを含まない生理食塩水をラットに投与したこと以外は、上記実験を繰り返した例(比較例)も行なった。その結果、比較例の骨密度が1.010mg/mmであったのに対し、実施例1の骨密度は1.095mg/mmであった。
Example 1 (Anti-osteoporosis effect)
Osteoporosis Improvement Effect Test SD rat (22 weeks old) Female ovaries were surgically removed to create osteoporosis model rats. Ovariectomized rats were divided into 6 groups of 7 animals, and a liquid in which physiological saline was dissolved was orally administered every other day (total 17 times) during the 35-day test period so that the HMB was 30 mg / kg. The feed was the solid feed CRF-1 for mice, rats and hamsters from Oriental Yeast Co., Ltd. There was no difference in food intake between groups during the study period. On the 35th day after the start of the test, the weight of the rat was measured, and then the femur was removed. The femur was used for analysis with the adhesive tissue and muscle removed. After measuring the volume of the femur, it was washed three times with ethanol, then washed three times with acetone, dried overnight, and then weighed to determine the dry weight of the femur. From the volume and dry weight, the bone density (dry weight g / volume mm 3 ) was measured. In addition, as a control experiment, an example (comparative example) in which the above experiment was repeated was performed except that physiological saline containing no HMB was administered to the rat. As a result, the bone density of the comparative example was 1.010 mg / mm 3 , whereas the bone density of Example 1 was 1.095 mg / mm 3 .

実施例2(抗鬱・抗ストレス効果)
HMBの治療効果を調べた。
マウス強制水泳試験による精神安定作用の評価
本発明の治療剤の評価は、1977年にPorsoltにより開発されたマウス強制水泳試験を採用した。本試験は鬱病の動物モデル実験として最も多用される方法のひとつである。本試験では、マウスをある限られたスペースの中で強制的に泳がせて「無動状態」を惹起させる。この無動状態は、ストレスを負荷された動物が水からの逃避を放棄した一種の「絶望状態」を反映するものと考えられ、ヒトにおける鬱状態、ストレス状態と関連づけられている。事実、抗鬱薬は特異的にこの状況下における無動状態の持続時間を短縮させることがわかっており、この短縮作用は臨床力価との間に有意な相関を有することが認められている。
Example 2 (Antidepressant / Anti-stress effect)
The therapeutic effect of HMB was examined.
Evaluation of tranquilizing effect by forced mouse swimming test The therapeutic agent of the present invention was evaluated by the forced mouse swimming test developed by Porsolt in 1977. This is one of the most frequently used animal model experiments for depression. In this test, the mouse is forced to swim in a limited space to cause “immobility”. This immobility state is thought to reflect a kind of “despair state” in which stressed animals abandon their escape from water, and is associated with depression and stress in humans. In fact, antidepressants have been found to specifically reduce the duration of immobility in this situation, and this shortening has been found to have a significant correlation with clinical titer.

本試験方法は次のとおりである。
25℃の水を深さ15cmまで入れたプラスチック円筒中でマウスを強制水泳させる。5分間の強制水泳後、30℃の乾燥機中で15分間乾燥し、ホームケージに戻す。翌日マウスに試験試料を腹腔内投与して、その1時間後に再び5分間の強制水泳を課し、現れた無動状態の持続時間をストップウォッチを用いて測定する。マウスが水に浮かんで静止している状態を無動状態と判定する。無動状態持続時間については有意差検定を行い、統計学的に有意差を検定する。実験には雄のddYマウスを使用し、1群6匹とする。なお、試験は全て午後1時から午後6時の間に行う。また、ポジティブコントロールとして抗鬱薬であるイミプラミンを用いた試験も行う。
The test method is as follows.
Mice are forced to swim in a plastic cylinder containing 25 ° C. water to a depth of 15 cm. After forced swimming for 5 minutes, dry in a dryer at 30 ° C. for 15 minutes and return to the home cage. On the next day, the test sample is intraperitoneally administered to the mouse, one hour later, forced swimming for 5 minutes is imposed again, and the duration of the immobility that appears is measured using a stopwatch. A state in which the mouse floats on the water and is stationary is determined as an immobile state. For the duration of stationary state, a significant difference test is performed, and a statistically significant difference is tested. For the experiment, male ddY mice are used, and there are 6 mice per group. All tests are conducted between 1pm and 6pm. A test using imipramine, an antidepressant, as a positive control will also be conducted.

その結果、HMBのCa塩を30mg/kg投与したマウスの無動状態持続時間は、178.8±2.8秒であった。コントロール(生理食塩水のみ)は209.0±3.2秒であった。ポジティブコントロール(30mg/kg投与)のマウスの無動状態持続時間は、181.2±4.6秒であった。本実施例およびポジティブコントロールの無動状態持続時間は、危険率1%で有意差を有する。   As a result, the duration of immobility in mice administered with 30 mg / kg of HMB Ca salt was 178.8 ± 2.8 seconds. The control (saline only) was 209.0 ± 3.2 seconds. The duration of immobility in the positive control (30 mg / kg dose) mice was 181.2 ± 4.6 seconds. The duration of immobility in this example and the positive control is significantly different at a risk rate of 1%.

実施例3(血圧降下効果)
HMBカルシウム塩を一般市販飼料(船橋農場製、船橋SP)に添加し、脳卒中易発症性高血圧自然発症ラット(SHR−SP)を用いて最高血圧値、体重の変化を比較した。対照区は、HMBカルシウム塩を添加しない一般試料を用いた。A区を対照区、B区を本発明区とし、それぞれの飼料で5週齢の雄性SHR−SPを各区6匹ずつ7週間飼育し、12週齢に達した時の血圧値と体重の変化について調べた。表1に示すように血圧の変化においては、本発明区に有意な血圧上昇の抑制が認められた。なお、本発明区においては、HMBカルシウム塩の1日あたりの摂取量が、50mg/kg体重となるように飼料中のHMBカルシウム塩の濃度を調整した。
Example 3 (blood pressure lowering effect)
HMB calcium salt was added to a general commercial feed (Funabashi Farm, Funabashi SP), and the changes in systolic blood pressure and body weight were compared using stroke-prone spontaneously hypertensive rats (SHR-SP). As a control group, a general sample to which no HMB calcium salt was added was used. The A group is the control group and the B group is the present invention group, and each group of 6-week-old male SHR-SPs is bred for 7 weeks, and changes in blood pressure and body weight when they reach 12 weeks of age. Investigated about. As shown in Table 1, in the change of blood pressure, significant suppression of blood pressure increase was observed in the present invention group. In the present invention, the concentration of HMB calcium salt in the feed was adjusted so that the daily intake of HMB calcium salt was 50 mg / kg body weight.

実施例4(抗糖尿病効果)
6週齢の雄性SD系ラット(1群6匹)の尾静脈にストレプトゾトシンを1回投与することにより糖尿病を惹起した。
HMBの投与量を30mg/kgとし、ストレプトゾトシン(STZ)投与の1時間前に経口投与し、その翌日より1日1回13日間連続経口投与した。最終投与の翌日に50%グルコース水溶液(10ml/kg)を経口投与し、経時的に血糖値(mg/dl)を測定(o−トルイジン・ホウ酸)した。
Example 4 (anti-diabetic effect)
Diabetes was induced by administering streptozotocin once to the tail vein of 6-week-old male SD rats (6 rats per group).
The dose of HMB was 30 mg / kg, and it was orally administered 1 hour before the administration of streptozotocin (STZ), and was orally administered once a day for 13 days from the next day. The day after the final administration, 50% glucose aqueous solution (10 ml / kg) was orally administered, and blood glucose level (mg / dl) was measured over time (o-toluidine / boric acid).

なお、正常対照群としてSTZを投与せずに滅菌水のみを投与した群、病態対照群としてSTZを投与して滅菌水を投与した群、および陽性対照群としてSTZを投与してニコチン酸アミド(50mg/kg)を投与した群を設けた。ニコチン酸アミドはSTZ糖尿病モデルに対して有効であることが報告されている(新薬開発のための動物利用集成,419−422頁,R&Dプランニング,1985年)。   In addition, as a normal control group, a group in which only sterile water was administered without administering STZ, a group in which STZ was administered and sterilized water was administered as a disease state control group, and STZ was administered as a positive control group and nicotinamide ( 50 mg / kg) was provided. Nicotinamide has been reported to be effective against STZ diabetes models (Animal utilization for new drug development, 419-422, R & D planning, 1985).

糖尿病は糖代謝能力が低下し高血糖を呈する疾患である。本実施例においてはグルコース投与1時間後に血糖値のピークを認めるが、病態対照群では最高血糖値が338mg/dlであり、正常対照群では最高血糖値は165mg/dlであった。病態対照群の最高血糖値は正常対照群のそれと比較して約2倍を示し、病態対照群では糖代謝能力の低下が認められた。   Diabetes is a disease in which the ability to metabolize glucose is reduced and hyperglycemia occurs. In this example, a peak of blood glucose level was observed 1 hour after glucose administration, but the maximum blood glucose level was 338 mg / dl in the pathological control group, and the maximum blood glucose level was 165 mg / dl in the normal control group. The maximum blood glucose level of the pathological condition control group was about twice that of the normal control group, and a decrease in glucose metabolism ability was observed in the pathological condition control group.

HMBの活性は、式1により病態対照群の血糖値に対する抑制率(%)を算出した。   For the activity of HMB, the inhibition rate (%) with respect to the blood glucose level of the pathological condition control group was calculated by Formula 1.

(式1)
抑制率(%)=〔1−(HMB投与群または陽性対照群の最高血糖値−正常対照群の最高血糖値)/(病態対照群の最高血糖値−正常対照群の最高血糖値)〕×100
(Formula 1)
Inhibition rate (%) = [1- (high blood sugar level of HMB administration group or positive control group−high blood sugar level of normal control group) / (high blood sugar level of disease state control group−high blood sugar level of normal control group)] × 100

その結果、HMB投与群の抑制率は58.2%であった。陽性対照群の抑制率は43.0%であった。したがって、HMB投与群は、病態対照群に比較して、優れた血糖値の低下が認められ、糖代謝能力が改善されていた。   As a result, the suppression rate of the HMB administration group was 58.2%. The suppression rate of the positive control group was 43.0%. Therefore, in the HMB administration group, an excellent decrease in blood glucose level was observed and the glucose metabolism ability was improved as compared with the pathological condition control group.

実施例5(抗アレルギー効果)

実施例7(抗疲労効果)
STD DDY 雄性マウス(5週齢:各群n=3〜4)に対し、HMBを経口摂取させた。摂取量は、30mg/kg体重である。摂取は、純水にHMBを溶解させた溶液を用いて行なった。なお、コントロール群のマウスには、純水のみを摂取させて試験を行った。
Example 7 (Anti-fatigue effect)
STD DDY male mice (5 weeks old: each group n = 3 to 4) were orally ingested with HMB. The intake is 30 mg / kg body weight. Ingestion was performed using a solution in which HMB was dissolved in pure water. In addition, the test group mice were fed with pure water only.

摂取から30分後に、マウスを深さ80センチの水槽に入れて、無動に至るまでの時間を計測した。各試験群のマウス(各群n=3〜4)の無動に至るまでの時間の平均値として、コントロール群は約112秒であったのに対し、HMB投与群は、約256秒であった。
以上から、HMBに高い抗疲労効果が確認された。
Thirty minutes after the ingestion, the mouse was placed in an 80 cm deep water tank, and the time until immobility was measured. The average value of the time required until the mice of each test group (n = 3 to 4) reached immobility was about 112 seconds for the control group, and about 256 seconds for the HMB administration group. It was.
From the above, a high anti-fatigue effect was confirmed for HMB.

実施例8(メラニン抑制効果)
メラニンを生成する細胞として、マウス由来の培養B16メラノーマ細胞を用いてウシ胎児血清を終濃度10%になるように添加したイーグルMEM培地で培養し、該細胞を3×103cell/mlの濃度で6ウェルプレートの各ウェルに6ml播種し、5日間COインキュベーター内で培養後、HMBのCa塩を添加した培地に交換し、さらに3日間同条件で培養する。細胞を洗浄後、細胞をスクレーパー処理により剥がし、ドデシル硫酸ナトリウム(SDS)により可溶化して475nm、260nmの吸光度を測定し、S475、S260とする。メラニン抑制率は被検試料を添加しない培地で培養した細胞の475nm、260nmにおける吸光度をC475、C260として式1により計算した。ポジティブコントロールとしてコウジ酸(Kojic acid)を用いた。
Example 8 (melanin inhibitory effect)
As a melanin-producing cell, a mouse-derived cultured B16 melanoma cell is used and cultured in an Eagle's MEM medium supplemented with fetal bovine serum to a final concentration of 10%, and the cell is cultured at a concentration of 3 × 10 3 cells / ml. Inoculate 6 ml in each well of a 6-well plate, and after culturing in a CO 2 incubator for 5 days, replace with a medium supplemented with HMB Ca salt, and further culture under the same conditions for 3 days. After washing the cells, the cells are peeled off by a scraper treatment, solubilized with sodium dodecyl sulfate (SDS), and the absorbance at 475 nm and 260 nm is measured to obtain S 475 and S 260 . The melanin inhibition rate was calculated by Equation 1 with the absorbance at 475 nm and 260 nm of cells cultured in a medium not added with the test sample as C 475 and C 260 . As a positive control, kojic acid was used.

Figure 2009155336
Figure 2009155336

その結果、ポジティブコントロール(培地中にコウジ酸3mM添加)のメラニン抑制率は約56%であり、HMBのCa塩を添加した被験試料(培地中にHMBのCa塩を500μg/ml添加)のメラニン抑制率は約58%であった。   As a result, the melanin inhibition rate of the positive control (addition of 3 mM kojic acid in the medium) was about 56%, and the melanin of the test sample (added 500 μg / ml of HMB Ca salt in the medium) added with Ca salt of HMB. The inhibition rate was about 58%.

実施例9(シワ形成抑制効果)
5匹ずつ2群のヘアレスマウスの背部に、UVB(長波長紫外線)を10週間照射してシワ形成モデルを作製した。その後、このシワ形成モデルの1群にはHMBを0.5質量%の割合で10%エタノール水溶液に溶解した液体を(実施例1)、もう1群には10%エタノール水溶液のみを(比較例)、シワが形成された背部に1日1回、週に5日の割合で4週間塗布し続けた。4週間の塗布期間終了後、各モデルの背部からレプリカを採取し、得られたレプリカのそれぞれについて、次の基準に従ってシワスコアを付した。
(シワスコア基準)
0:方向性のある構造は認められない。
1:繊維状の細い構造が方向性をもって認められる。
2:方向性をもった繊維状の細い構造とともに太い棒状の構造が認められる。
3:方向性をもった太い棒状の構造が認められる。
Example 9 (wrinkle formation inhibitory effect)
A wrinkle formation model was prepared by irradiating UVB (long wavelength ultraviolet rays) for 10 weeks on the back of two groups of hairless mice, each of 5 mice. After that, one group of this wrinkle formation model contains a liquid obtained by dissolving HMB in a 10% ethanol aqueous solution at a ratio of 0.5% by mass (Example 1), and the other group contains only a 10% ethanol aqueous solution (Comparative Example). ), And continued to be applied once a day on the back where wrinkles were formed at a rate of 5 days per week for 4 weeks. After the application period of 4 weeks, replicas were collected from the back of each model, and wrinkle scores were assigned to each of the obtained replicas according to the following criteria.
(Wrinkle score standard)
0: Directional structure is not recognized.
1: A fibrous thin structure is recognized with directionality.
2: A thick rod-like structure is recognized together with a fibrous thin structure having directionality.
3: A thick rod-like structure with directionality is observed.

上記シワスコアを用いた評価は、レプリカ上の方向性をもった線状の構造をシワとして定義して評価したものである。したがって、上記シワスコア基準に従えば、スコアが高いほどシワ形成が進んだ皮膚状態と評価される。上記で得られたシワスコアについて各群の平均値を算出したところ、実施例9は0、比較例は1.0であった。両群のシワスコアについて、Mann−Whitney検定により有意差検定を行ったところ、実施例9のシワスコアは、比較例のシワスコアに比べ、危険率0.05以下で有意に小さかった。   The evaluation using the wrinkle score is an evaluation by defining a linear structure with directionality on a replica as a wrinkle. Therefore, according to the wrinkle score standard, the higher the score, the better the skin state where wrinkle formation has progressed. When the average value of each group was computed about the wrinkle score obtained above, Example 9 was 0 and the comparative example was 1.0. When the wrinkle score of both groups was subjected to a significant difference test by Mann-Whitney test, the wrinkle score of Example 9 was significantly smaller than the wrinkle score of the comparative example at a risk rate of 0.05 or less.

実施例12(養毛・育毛効果)
特許第4041451号公報に記載の実験手順に従い、HMBの効果を検証した。
(1)マウスによる試験
C3Hマウス(8週齢、オス、平均体重35g)の背部皮膚(2cm×4cm)を電気バリカン及びシェーバーで刈り、翌日より実施例の各試料を被験部皮膚に朝夕2回、一匹当り0.2mLを二週間連用塗布した。一試料に対して動物一群10匹使用した。塗布開始22日目に各試料の被験部皮膚をビデオカメラに撮影し、画像解析装置にて毛刈り部及び発毛部の面積を測定した。養毛効果の判定は、下記に示す発毛率(%)を算出し、実施例の各群の発毛率平均値を求めて比較を行った。
発毛率(%)=(発毛部の面積)/(毛刈り部の面積)×100
Example 12 (Hair restoration / hair growth effect)
The effect of HMB was verified according to the experimental procedure described in Japanese Patent No. 4041451.
(1) Tests with mice The back skin (2 cm x 4 cm) of C3H mice (8 weeks old, male, average body weight 35 g) was cut with an electric clipper and shaver, and each sample of the examples was applied to the test subject skin twice a day in the morning and evening. Then, 0.2 mL per animal was applied continuously for 2 weeks. A group of 10 animals was used for one sample. On the 22nd day from the start of application, the skin of the test area of each sample was photographed with a video camera, and the areas of the hair cutting part and the hair growth part were measured with an image analyzer. The determination of the hair nourishing effect was carried out by calculating the hair growth rate (%) shown below, and calculating the average hair growth rate of each group in the examples for comparison.
Hair growth rate (%) = (Area of hair growth part) / (Area of hair cutting part) × 100

(2)ヒトによる試験
男性型脱毛症患者である被験者10名の耳上5cmの位置にて、頭髪を左右2ヶ所直径5mmの円形状に剃毛し、実施例の各試料を左側の頭髪全体に毎日朝夕2回、約3mL塗布し、右側は何も塗布せずに、左右の比較を行った。毛成長速度の効果の判定は、試験開始後1ヶ月目に、左右の剃毛した部位の被験部毛髪20本を抜毛し、下記式で求めた値で毛成長速度を評価した。
毛成長速度=(左側毛髪20本の長さの平均)÷(右側毛髪20本の長さの平均)
(2) Human test At 10 cm above the ears of 10 subjects with male pattern baldness, the hair was shaved into a circular shape with a diameter of 5 mm at two locations on the left and right, and each sample of the example was placed on the entire left hair. About 3 mL was applied twice a day in the morning and evening, and the right and left sides were compared without applying anything on the right side. In the determination of the effect of the hair growth rate, the hair growth rate was evaluated with the value obtained by the following formula after removing 20 test part hairs at the left and right shaved sites 1 month after the start of the test.
Hair growth rate = (average length of 20 left hairs) ÷ (average length of 20 right hairs)

また、育毛効果、痒み防止効果、脱毛効果、ふけ防止効果の判定は、試験開始後3ヶ月目に各項に対し、右側の何も塗布していない被試部位と比較して、「産毛が剛毛化した或いは産毛が増加した」、「痒みをそれほど感じない」、「抜け毛が少なくなった」、「ふけが少なくなった」と回答した人数で示した。   In addition, the hair growth effect, the itch prevention effect, the hair loss effect, and the anti-dandruff effect were determined for each item 3 months after the start of the test, compared to the test site where nothing was applied on the right side. It was shown by the number of respondents who responded that they became bristle or increased their vellus hair, “doesn't feel itchy much”, “has lost hair loss”, and “had less dandruff”.
