However, the technical scope of the present invention should not be construed as being limited to these examples. In addition, in the following examples etc., what is indicated as “%” and indicates the blending amount means wt% unless otherwise specified. First, in order to examine the blood circulation promoting action of the active ingredient of the external preparation of the present invention, a blood flow increase test was conducted.

1.血流増加試験
試験サンプルとして、1)0.75%アデノシン、2)0.75%ニコチン酸アミド及び3)プラセボ製剤を調製した。また、被検者は、健常人パネル(20〜60歳の男女16名)とした。
1. As blood flow increase test test samples, 1) 0.75% adenosine, 2) 0.75% nicotinamide and 3) placebo preparation were prepared. Moreover, the test subject was a healthy person panel (16 men and women of 20-60 years old).

パネルを、恒温・恒湿室(25℃)内で、30分間安静させた。その後、手首に近い方から、5cm以上の間隔を空けて、測定部位A,B,Cを定め、レーザードップラー計(OMEGA-FLOW FLO-N1)で、各部位の血流量を事前測定した(0時間のデータに該当する)。   The panel was allowed to rest for 30 minutes in a constant temperature / humidity chamber (25 ° C.). After that, measurement sites A, B, and C were determined at intervals of 5 cm or more from the side closer to the wrist, and the blood flow volume at each site was measured in advance with a laser Doppler meter (OMEGA-FLOW FLO-N1) (0 Corresponds to time data).

なお、測定部位1か所に付き、プローブ及び血流計を各1台準備した(本試験では、測定部位の数に応じ、各3台を準備した)。上記の事前測定後、各試験サンプルを、直径8mmの各測定部位A,B,Cに10μL 塗布した。次いで、塗布1時間後までの、血流量(V:ボルト)及び血流速度(V:ボルト)を、5分毎にモニタリングし、各値を、パネル全員の平均値として算出した。   In addition, one probe and a blood flow meter were prepared for each measurement site (three units were prepared for each test according to the number of measurement sites). After the above preliminary measurement, 10 μL of each test sample was applied to each measurement site A, B, C having a diameter of 8 mm. Subsequently, blood flow volume (V: volt) and blood flow velocity (V: volt) until 1 hour after application were monitored every 5 minutes, and each value was calculated as an average value of all the panels.

0時間における上記血流量に対する時間毎の血流量の比(%)を、血行促進効果の指標として、各試験サンプルの血行促進効果を評価した。結果を、第1図に示す。   The blood flow promoting effect of each test sample was evaluated using the ratio (%) of the blood flow volume per hour to the blood flow volume at 0 hour as an index of the blood circulation promoting effect. The results are shown in FIG.

第1図において、試験開始後30分以降に、著しくパネルの血行が促進されたことが判明した。この結果により、本発明に係わる有効成分のアデノシンに優れた血行促進作用が認められることが判明した。   In FIG. 1, it was found that the blood circulation of the panel was remarkably promoted after 30 minutes from the start of the test. From this result, it was found that an excellent blood circulation promoting action was recognized by the active ingredient adenosine according to the present invention.

また、0.75%アデノシン5’−リン酸についても、上記と同様の試験を行った。その結果、アデノシン5’−リン酸についても、著しい血行促進作用が認められた。   A test similar to the above was performed for 0.75% adenosine 5'-phosphate. As a result, a significant blood circulation promoting action was also observed for adenosine 5'-phosphate.

よって、アデノシン、アデノシン5’−リン酸及び/又はアデノシン5’−リン酸の塩を有効成分とすることにより、優れた血行促進を発揮する剤が提供されることが見出された。   Therefore, it has been found that an agent exhibiting excellent blood circulation promotion can be provided by using adenosine, adenosine 5'-phosphate and / or a salt of adenosine 5'-phosphate as an active ingredient.
