［血液改質剤を含む血液の表面張力］
血液改質剤を含む血液の表面張力を、協和界面科学社製接触角計ＤｒｏｐＭａｓｔｅｒ５００を用い、ペンダントドロップ法にて測定した。表面張力は、ヒツジ脱繊維血に、所定の量の血液改質剤を添加し、十分振とうした後に測定した。測定は、機器が自動で行うが、表面張力γは、以下の式により求められる（図１７を参照）。 [Example 6]
[Surface tension of blood containing blood modifying agents]
The surface tension of blood containing a blood modifying agent was measured by a pendant drop method using a contact angle meter Drop Master 500 manufactured by Kyowa Interface Science Co., Ltd. The surface tension was measured after adding a predetermined amount of blood modifying agent to sheep defibrinated blood and shaking sufficiently. Although the measurement is automatically performed by the instrument, the surface tension γ is obtained by the following equation (see FIG. 17).
