    Abstract: In accordance with the present invention, a method is provided for treating tumors. More particularly, the present invention relates to a method for treating tumors comprising injecting a solution of certain ethylene oxide-propylene oxide surface-active copolymers and a solution containing chemotherapeutic agents into a human or animal with a tumor. The solutions can be injected simultaneously or separately at different times. In addition, the surface-active copolymer and the chemotherapeutic agent can be in the same solution. The surface-active copolymer can be an ethylene oxide-propylene oxide condensation product with the following general formula:HO(C.sub.2 H.sub.4 O).sub.b (C.sub.3 H.sub.6 O).sub.a (O.sub.2 H.sub.4 O).sub.b Hwherein a is an integer such that the hydrophobe represented by (C.sub.3 H.sub.6 O) has a molecular weight of approximately 950 to 4000 daltons, preferably approximately 1200 to 3500 daltons, 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.

    Abstract: This invention provides an improved method for enhancing the activity of thrombolytic agents, including t-PA, scu-PA, tcu-PA, streptokinase, acylated plasminogen-streptokinase activator complex (APSAC), mixtures of these, and other activators of plasminogen. The enhancement method comprises supplementation of plasma plasminogen levels with deglycosylated forms of glu- and lys-plasminogen. Deglycosylated plasminogen refers herein to glu- or lys-plasminogen 2 having a single oligosaccharide chain at Thr.sub.345, plasminogens having a single oligosaccharide chain at Asn.sub.288, and unglycosylated forms of plasminogen. The work described herein shows that a less glycosylated form of plasminogen (glu-plasminogen 2) has a higher affinity for fibrin clots than a more glycosylated plasminogen (glu-plasminogen 1). Based on this work, it is believed that glycosylation of plasminogen inhibits binding of plasminogen to fibrin clots, perhaps due to steric hindrance, and further, that deglycosylated forms of plasminogen may be more effective enhancers of scu-PA in thrombolytic therapy than fully glycosylated forms of plasminogen. Improved enhancement of the activity of thrombolytic agents allows the use of lower therapeutic doses and thus, is expected to relieve some of the bleeding and other side effects of thrombolytic therapy.

    Abstract: A method of adjunctive therapy to inhibit reocclusions in a patient, e.g., after thrombolytic therapy or angioplasty, by administering to the patient a bolus of an amount of purified pro-urokinase ("pro-UK") that inhibits the formation of occlusive thrombi without inducing a systemic effect in the patient, the pro-UK is administered after the completion of the thrombolytic treatment and periodically thereafter for the duration of therapy, and becomes incorporated into the outer membrane of the platelets of the patient, thereby increasing the T.sub. 1/2 of the pro-UK in plasma, which is about 7 to 8 minutes, to about 4 to 5 days, and inhibiting reocclusion without inducing a systemic effect.
