Description

ステップS41において、スクリーニング試料の染色部分の面積Atと、スクリーニング対照試料の染色部分の面積Acとを比較する。
面積の比較は、面積の絶対値の比較であっても良く、スクリーニング対照試料の面積を100%とした場合における面積の割合の比較であってもよい。
複数のスクリーニング試料について評価を行う場合には、スクリーニング対照試料の面積を100%とした比較を行うのが好ましい。
In step S41, the area At of the stained portion of the screening sample and the area Ac of the stained portion of the screening control sample are compared.
The area comparison may be a comparison of the absolute value of the area, or may be a comparison of the ratio of the area when the area of the screening control sample is 100%.
When evaluating a plurality of screening samples, it is preferable to make a comparison with the area of the screening control sample as 100%.

一方で、面積Atが面積Acと同一、又は面積Atが面積Acより大きい高い場合(面積At 面積Ac)にはステップS43に移行し、当該スクリーニング試料に添加した探索対象成分は、接着タンパク質の量を減少する作用を有さない成分であると評価する。 On the other hand, when the area At is the same as the area Ac or the area At is higher than the area Ac (area At area Ac), the process proceeds to step S43, and the search target component added to the screening sample is the adhesive protein. It is evaluated as a component that does not have the effect of reducing the amount.

(2)被験者及び測定部位
本実施例では、40歳から52歳の女性20名を被験者とした。
そして、本実施例では、被験者顔面における、シミが存在する部位(92箇所)を測定部位として選定した。
各被験者のシミが存在する部位に、製造例の乳液を1日2回塗布し、これを12週間続けた。
(2) Subjects and measurement sites In this example, 20 women aged 40 to 52 years were used as subjects.
Then, in this embodiment, the sites (92 sites) where the stains are present on the subject's face were selected as the measurement sites.
The emulsion of Production Example 2 was applied to the spots of each subject twice a day, and this was continued for 12 weeks.

解析用画像全体の面積を100%として、蛍光部分の面積を算出した。結果を表5、表6、及び図17(代表)、図18、19に示す。なお、乳液使用12週間経過後のデータは、シミ部位9箇所のうち、80箇所のデータを集計し、同箇所における乳液使用前のデータと比較した。また、図18において、**はp<0.01であり、図19において、***はp<0.001である。 The area of the fluorescent portion was calculated with the area of the entire analysis image as 100%. The results are shown in Tables 5, 6, and 17 (representative), 18 and 19. As for the data after 12 weeks of using the emulsion, the data of 80 of the 92 spots were aggregated and compared with the data before using the emulsion at the same site. Further, in FIG. 18, ** is p <0.01, and in FIG. 19, *** is p <0.001.
