(57) [Summary] [Objective] A surfactant is contained and an oxygen scavenger such as a free radical or a superoxide disproportionation enzyme or mannitol can be dissolved to dissolve fibrin or to dissolve blood clots in blood vessels. Providing a mixture or drug. [Structure] HO (C 2 H 4 O) b (C 3 H 6 O) a (C 2 H containing an oxygen group scavenger and a surface-active copolymer represented by the following formula: 4 O) b H where a is an integer such that the hydrophobic moiety represented by (C 3 H 6 O) has a molecular weight of about 950 to 4000, and b is (C 2 H 4 O). A fibrinolytic mixture, or an agent for dissolving blood clots in blood vessels, characterized in that the hydrophilic part is an integer such that it constitutes about 50 to 90% by weight of the surface-active copolymer. |
