Description

【0001】
【発明の属する技術分野】
本発明は、紫外線曝露に起因する皮膚障害を抑制する作用を有する皮膚障害抑制剤、紫外線曝露に起因する皮膚障害を改善する作用を有する皮膚障害改善剤、及びそれらを含有する皮膚外用剤に関する。更に詳細にはエルゴカルシフェロール及び/又はコレカルシフェロールを含有し、紫外線曝露に起因する皮膚障害を抑制する作用を有する皮膚障害抑制剤、及び紫外線曝露に起因する皮膚障害を改善する作用を有する皮膚障害改善剤に関するものである。更に、その皮膚障害抑制剤、皮膚障害改善剤を含有し、紫外線曝露によるシワ形成、皮膚腫瘍、皮膚肥厚及び皮膚硬化を抑制、改善し、化粧品や医薬品として有用である皮膚外用剤に関する。
【0002】
【従来の技術】
紫外線(太陽光)の連続的な長期間曝露は皮膚にケミカルメディエーター、サ
イトカイン等による炎症を生じせしめ、シワ、タルミ、皮膚肥厚、皮膚硬化、皮膚癌、日光性弾性線維症等の皮膚障害が生じる(非特許文献1参照)。特に表皮及び真皮が肥厚することにより、皮膚の弾性、保湿性が低下し、これが皮膚老化の要因の一つとなっていると考えられている。そこで、従来からこれらの障害を防ぐために、紫外線吸収剤(特許文献1、非特許文献2参照)、紫外線散乱剤(非特許文献3参照)が配合された外用剤、すなわち乳液、クリーム、ローション、美容液、ファンデーション、軟膏、パップ剤、貼付剤等が使用されている。
又、加齢、紫外線曝露等により生じる皮膚のシワやタルミ、ハリや弾力性の低下を予防、あるいは改善するために、レチノイン酸(非特許文献4参照)、抗炎症薬(非特許文献5参照)やオウバクエキス、シラカンバエキス、セージエキス、ローマカミツレエキス等(特許文献2参照)、メリッサ抽出物等(特許文献3参照)が配合されている。
しかしながら、例えば、レチノイン酸を配合した皮膚外用剤は、真皮上層にコラーゲンを増殖させシワ改善効果は有するが、シワの発生を抑制する効果はなく、塗布を中止すると元に戻ってしまい、また、塗布部位に紫外線が曝露すると却って皮膚癌を誘発する等の問題がある。紫外線吸収剤、紫外線散乱剤、抗炎症薬、植物抽出物等を配合した他の皮膚外用剤においても、シワ形成、皮膚腫瘍、皮膚肥厚等の抑制・改善効果が十分ではなかったり、効果を高めるためにこれらの添加物を高濃度に配合すると製剤の使用感が損なわれたり、高温時や経時で変質する等の問題が生じる場合があった。そこで、外用剤の剤型や使用感に影響を与えず、紫外線(太陽光)曝露によるシワ形成、皮膚腫瘍、皮膚肥厚及び皮膚硬化
症等の皮膚障害の発現を抑制する皮膚障害抑制剤、又、発現した皮膚障害を改善する皮膚障害改善剤、及びそれらを含有する皮膚外用剤の開発が望まれていた。

【実施例】
次に実施例を挙げて本発明を更に詳細に説明するが、本発明はこれらに何ら制約されるものではない。
実施例1:ヘアレスマウス紫外線照射による皮膚障害抑制試験
下記調製方法により皮膚障害抑制剤を調製し、紫外線照射による皮膚肥厚、皮膚腫瘍、シワ形成、皮膚硬化、及び皮膚老化の各試験を行い、皮膚障害の抑制を評価した。
【0013】
[試料(皮膚障害抑制剤)の調製]
エルゴカルシフェロール、コレカルシフェロールを基剤(ポリエチレングリコール1000:エチルアルコール=1:1)に溶解し、表1に示す皮膚障害抑制剤1〜5を調製した。また、比較品には上記の基剤を用いた。
【0014】
[試料塗布法と紫外線照射法]
1群8匹とし、紫外線照射90分前に上述の試料(皮膚障害抑制剤)をヘアレスマウス(10週齢)背中に0.1g塗布し、一定量の紫外線(東芝BLBランプ)を1日2時間(5回/週)15週間照射し(総照射量:716J/cm)、皮膚肥厚、皮膚腫瘍、シワ形成及び皮膚硬化の抑制効果、並びに皮膚老化のマーカー物質抑制効果を調べた。
尚、これらの試料の紫外線吸収スペクトルを測定し、これらは評価試験に影響を与えないことを確認した。
【0015】
[評価法]
(皮膚肥厚抑制効果)
紫外線照射前と紫外線照射15週後の皮膚の厚みをダイアル厚みゲージ(OZAK.MFG.CO.LTD.)を用い測定した。結果は、8匹の皮膚の厚みの平均値、及び紫外線照射15週後の増加率で評価した。
(皮膚腫瘍抑制効果)
皮膚腫瘍は径が0.5mm以上の腫瘍を発症したマウスの発生率(8匹中)で評価した。
【0016】
(シワ形成抑制効果)
紫外線照射15週後のシワ形成について、下記表2に示す「光皮膚老化グレード」に基づいてシワグレードを判定した。尚、紫外線照射前のヘアレスマウスのシワグレードはいずれも0であった。結果は、8匹の評点の平均値で表し評価した。
【0017】
(皮膚硬化症の発現抑制効果)
紫外線照射15週後の各ヘアレスマウス皮膚背部中央部位を摘み、復元に5秒以上を要する皮膚を皮膚硬化症とし、マウス8匹中の発現率で評価した。
【0018】
(皮膚老化のマーカー物質抑制効果)
皮膚老化のマーカー物質であるデルマタン硫酸は、ヘアレスマウス背部皮膚を剥離し、コラーゲナーゼ及びコンドロイチナーゼで分解し、二単糖としてHPLC法により定量し、平均値を算出した。15週間後のデルマタン硫酸の生成抑制率は試料塗布群(本発明品塗布)のデルマタン硫酸の減少量をコントロール群(比較品塗布)のデルマタン硫酸量で割り、算出した。
【0019】
皮膚肥厚、皮膚腫瘍、シワ形成、皮膚硬化、及び皮膚老化マーカーについての各抑制評価結果を表1に示す。

[0002]
[Prior art]
Continuous long-term exposure to ultraviolet rays (sunlight) causes inflammation of the skin by chemical mediators, cytokines, etc., and causes skin disorders such as wrinkles, tallness, skin thickening, skin sclerosis, skin cancer, and solar elastosis. (See Non-Patent Document 1). In particular, it is considered that the thickening of the epidermis and dermis reduces the elasticity and moisturizing property of the skin, which is one of the factors of skin aging. Therefore, in order to prevent these obstacles, external preparations containing an ultraviolet absorber (see Patent Document 1 and Non-patent Document 2) and an ultraviolet scattering agent (see Non-Patent Document 3), that is, emulsions, creams, lotions, Essences, foundations, ointments, cataplasms, patches and the like are used.
In addition, retinoic acid (see Non-Patent Document 4), anti-inflammatory drugs (see Non-Patent Document 5) to prevent or ameliorate wrinkles and tallness, firmness and decreased elasticity of the skin caused by aging, exposure to ultraviolet light, etc. ), Oak extract, birch extract, sage extract, Roman chamomile extract and the like (see Patent Document 2), Melissa extract and the like (see Patent Document 3).
However, for example, a skin external preparation containing retinoic acid has a wrinkle-reducing effect by increasing collagen in the upper layer of the dermis, but has no effect of suppressing wrinkles and returns to its original state when application is stopped. Exposure of the application site to ultraviolet rays causes problems such as inducing skin cancer. Other skin external preparations containing UV absorbers, UV scattering agents, anti-inflammatory drugs, plant extracts, etc., have insufficient or improved effects of suppressing or improving wrinkle formation, skin tumors, skin thickening, etc. Therefore, if these additives are blended at a high concentration, there may be a problem that the feeling of use of the preparation is impaired, and the preparation deteriorates at high temperatures or over time. Therefore, a skin disorder suppressant that does not affect the dosage form or feeling of use of the external preparation and suppresses the appearance of skin disorders such as wrinkle formation, skin tumors, skin thickening and skin sclerosis due to exposure to ultraviolet rays (sunlight), There has been a demand for the development of skin disorder ameliorating agents for improving the developed skin disorders, and skin external preparations containing them.

【Example】
Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.
Example 1: Skin damage suppression test by ultraviolet irradiation of hairless mouse A skin damage inhibitor was prepared by the following preparation method, and each test of skin thickening, skin tumor, wrinkle formation, skin hardening, and skin aging by ultraviolet irradiation was performed. Disability suppression was evaluated.
[0013]
[Preparation of sample (skin damage inhibitor)]
Ergocalciferol and cholecalciferol were dissolved in a base (polyethylene glycol 1000: ethyl alcohol = 1: 1) to prepare skin disorder inhibitors 1 to 5 shown in Table 1. The above-mentioned base was used as a comparative product.
[0014]
[Sample coating method and UV irradiation method]
Each group consisted of 8 animals, and 90 minutes before ultraviolet irradiation, the above-mentioned sample (skin damage inhibitor) was applied to the back of a hairless mouse (10 weeks old) at 0.1 g, and a fixed amount of ultraviolet light (Toshiba BLB lamp) was applied 2 times a day. Irradiation was performed for 15 hours (5 times / week) for 15 weeks (total irradiation amount: 716 J / cm 2 ), and the effect of suppressing skin thickening, skin tumor, wrinkle formation and skin hardening, and the effect of suppressing marker substances of skin aging were examined.
The ultraviolet absorption spectra of these samples were measured, and it was confirmed that these samples did not affect the evaluation test.
[0015]
[Evaluation method]
(Skin thickening inhibitory effect)
The skin thickness before ultraviolet irradiation and 15 weeks after ultraviolet irradiation was measured using a dial thickness gauge (OZAK.MFG.CO.LTD.). The results were evaluated by the average value of the thickness of the skin of eight animals and the increase rate after 15 weeks of ultraviolet irradiation.
(Skin tumor inhibitory effect)
Skin tumors were evaluated by the incidence (out of 8) of mice that developed tumors having a diameter of 0.5 mm or more.
[0016]
(Wrinkle formation suppression effect)
Regarding the formation of wrinkles after 15 weeks of ultraviolet irradiation, the wrinkle grade was determined based on the “photo-skin aging grade” shown in Table 2 below. The wrinkle grade of the hairless mouse before ultraviolet irradiation was 0 in all cases. The results were expressed as the average of the scores of the eight animals and evaluated.
[0017]
(Effect of suppressing skin sclerosis)
The central part of the back of the skin of each hairless mouse 15 weeks after ultraviolet irradiation was removed, and the skin requiring 5 seconds or more for restoration was defined as skin sclerosis, and the expression rate in 8 mice was evaluated.
[0018]
(Skin aging marker substance suppression effect)
Dermatan sulfate, a marker substance for skin aging, was obtained by exfoliating the skin on the back of a hairless mouse, decomposing it with collagenase and chondroitinase, quantifying it as a disaccharide by the HPLC method, and calculating the average value. The suppression rate of dermatan sulfate production after 15 weeks was calculated by dividing the amount of decrease in dermatan sulfate in the sample application group (application of the present invention) by the amount of dermatan sulfate in the control group (application of comparison product).
