ABSTRACT:
In accordance with the present invention, a method and composition is provided for treating an animal or human with ischemic tissue. The method comprises injecting an effective amount of a free-radical scavenger and a surface-active copolymer into an animal or human with damaged tissue.
The surface-active copolymer can be an ethylene oxide-propylene oxide condensation product with the following general formula: ##STR1## wherein a is an interger such that the hydrophobe represented by (C.sub.3 H.sub.6 O) has a molecular weight of approximately 950 to 4000, preferably approximately 1200 to 3500, and b is an integer such that the hydrophile portion represented by (C.sub.2 H.sub.4 O) constitutes approximately 50% to 90% by weight of the compound.
