本発明によれば、簡易であり正確かつ客観的で、計測対象者に肉体的な負担をかけるといったことがない毛髪数の計測方法および発毛剤の効果の評価方法が提供される。 According to the present invention, there are provided a method for measuring the number of hairs and a method for evaluating the effects of hair growth agents, which are simple, accurate and objective, and do not impose a physical burden on the measurement subject.
以下、本発明の毛髪数の計測方法を工程毎に順を追って説明する。 Hereinafter, the method for measuring the number of hairs of the present invention will be described step by step.
工程(1)
まず、計測対象者の頭部に対して計測部位とする部位を含む部位を選定する。この工程は、発毛剤の効果を評価する際などにおいては、例えば、計測対象者(発毛剤の投与対象者)の頭部の脱毛部と有毛部の境界部分から行えばよい。
Process (1)
First, a part including a part to be measured with respect to the head of the measurement target is selected. This step may be performed, for example, from the boundary between the hair removal part and the hair part of the head of the measurement subject (the subject to whom the hair growth agent is administered) when evaluating the effect of the hair growth agent.
工程(2)
次に、選定部位に生えている毛髪を0.5mm〜3mmの長さに必要に応じてカットする。この工程は、毛髪数の計測を正確に行うために重要な工程であり、例えば、計測部位の面積を0.8cm2〜1.2cm2とする場合、選定部位に1.5cm×1.5cm程度の四角形の穴の開いたプレートをあて、開口部からはみ出た毛髪をカットすることにより行えばよい。毛髪は1mm〜2mmの長さにカットすることが望ましい。
Step (2)
Next, the hair growing on the selected part is cut to a length of 0.5 mm to 3 mm as necessary. This step is an important step in order to perform accurate measurements of the number of hairs, for example, if the area of the measurement portion and 0.8cm 2 ~1.2cm 2, 1.5cm × 1.5cm to selected sites What is necessary is just to cut the hair which protruded from the opening part by applying the plate with the hole of about a square. It is desirable to cut the hair to a length of 1 mm to 2 mm.
工程(3)
次に、選定部位をデジタルカメラで撮影することで、その画像データを取得する。この工程は、例えば、市販のマイクロスコープ(MORITEX社製のコンピュータ一体型CCDカメラ付マイクロスコープシステムMS−2000RSなど)を用い、一定倍率(10倍〜20倍が望ましい)で拡大撮影することにより行うことが望ましい。この際、カメラレンズと頭皮の距離を常に一定にするため、カメラの先端に接触ドームを接続し、接触ドームの先端を頭皮に垂直にあてた場合にカメラのピントがあうように設定して撮影することが望ましい(図1参照)。
Process (3)
Next, the selected part is imaged with a digital camera to acquire the image data. This step is performed, for example, by using a commercially available microscope (such as a microscope system MS-2000RS with a computer-integrated CCD camera manufactured by MORITEX, Inc.) at a constant magnification (preferably 10 to 20 times). It is desirable. At this time, in order to keep the distance between the camera lens and the scalp constant, a contact dome is connected to the tip of the camera, and the camera is set to focus when the tip of the contact dome is perpendicular to the scalp. It is desirable to do so (see FIG. 1).
工程(4)
次に、選定部位の画像データをコンピュータに取り込んで画面上に表示し、画面上に表示した画像の中から所定面積の計測部位を決定する(図2参照)。そして、画面上で計測部位に生えている毛髪1本一本に対してタグマークを付与する。計測効率や毛髪数の変化を正確に捉えることなどを鑑みれば、計測部位の面積は0.8cm2〜1.2cm2とすることが望ましい。画面上で計測部位に生えている毛髪1本一本に対してタグマークを付与する際、基準太さの寸法の画像を計測部位の画像と同じ倍率で画面上に表示し、計測部位に生えている毛髪の太さを基準太さと比較し、基準太さよりも細い場合と同じ太さ以上の場合とで付与するタグマークの種類を変え、異なるタグマークを別々に自動集計することで、毛髪の種類を太さによって2種類に分類し、それぞれの毛髪数の計測を別々に行うようにしてもよい(図3参照)。例えば、基準太さを40μmに設定し、基準太さよりも細い毛髪を軟毛(vellus hair,毛髪の種類:短くて細く色素のない毛髪である軟毛)、基準太さと同じ太さ以上の毛髪を非軟毛(non−vellus hair,毛髪の種類:長くて太く色素のある毛髪である硬毛と中間の長さ・太さで色素のある毛髪である中間毛)に分類し、それぞれに対して付与したタグマークを別々に自動集計することで、軟毛の毛髪数の計測と非軟毛の毛髪数の計測を別々に行うことができる。なお、画像データをコンピュータに取り込む際には、デジタルカメラから直接取り込むようにしてもよいし、いったん画像データをCD−Rなどの記録媒体に保存し、記録媒体から取り込むようにしてもよい。
Step (4)
Next, the image data of the selected part is taken into a computer and displayed on the screen, and a measurement part having a predetermined area is determined from the image displayed on the screen (see FIG. 2). Then, a tag mark is given to each hair growing on the measurement site on the screen. In view of such accurately grasp that the change in the measurement efficiency and speed hair, the area of the measurement region is preferably set to 0.8cm 2 ~1.2cm 2. When a tag mark is attached to each hair that grows on the measurement site on the screen, an image of the size of the reference thickness is displayed on the screen at the same magnification as the image of the measurement site, and grows on the measurement site. By comparing the thickness of the hair being compared with the reference thickness, changing the type of tag mark to be applied depending on whether it is thinner than the reference thickness or the same thickness or more, and automatically counting different tag marks separately, the hair May be classified into two types according to thickness, and the number of hairs may be measured separately (see FIG. 3). For example, if the reference thickness is set to 40 μm, hair thinner than the reference thickness is soft (vellus hair, hair type: soft hair that is short, thin, and has no pigment), and hair that is equal to or larger than the reference thickness is not covered Classified into soft hair (non-bell hair, type of hair: long and thick hair with pigment, and intermediate hair with pigment in the middle length and thickness) and applied to each By automatically counting the tag marks separately, the number of soft hairs and the number of non-soft hairs can be measured separately. When capturing image data into a computer, the image data may be directly captured from a digital camera, or the image data may be once stored in a recording medium such as a CD-R and captured from the recording medium.
工程(5)
最後に、画面上に付与したタグマークを自動集計することで毛髪数の計測を行う。タグマークの自動集計は、例えば、市販の画像解析・計測ソフトウェア(Media Cybernetics社製のImage−Pro−PLUS ver.4.0Jなど)を用いて行えばよい。
Process (5)
Finally, the number of hairs is measured by automatically counting the tag marks assigned on the screen. The automatic counting of tag marks may be performed using, for example, commercially available image analysis / measurement software (such as Image-Pro-PLUS ver. 4.0J manufactured by Media Cybernetics).
