めた。A group of 5 male ddY mice (5 weeks old, body weight: about 20 g) was used to intravenously, intraperitoneally and orally administer a physiological saline solution of the compound of the present invention to each mouse. After administration (10 minutes after intravenous administration and intraperitoneal administration, 30 minutes after oral administration), cut 2 cm from the tip of the tail of the mouse with a razor, and cut the opening in 6 ml of 3.8% sodium citrate aqueous solution. Insert into the blood vessel and collect blood for 1 minute after starting to bleed.
Then, it is hemolyzed with a QUIZ CLIZER (Toa Medical Electronics, containing 0.5% KCN), and the amount of blood that has flowed out is measured with an absorptiometer (wavelength: 540 nm, control solution: 3.8% sodium citrate aqueous solution). Further, physiological saline was administered to the mice in the control group. Then, the reduction rate of blood loss was calculated by the following formula.
