Urokinase type plasminogen activator (u-PA) was purified from three different chest fluids obtained from patients with liver cirrhosis and pleuritis, aplastic anemia and pneumonia, and lung tumor, and the relationship between molecular weight and plasminogen activator (PA) activity was examined by zymography. The molecular weights of u-PAs from the chest fluids were 200 Kd, 150-180 Kd, 95 Kd, 55 Kd, 44 Kd, 33 Kd and 14 Kd, and PA activity was observed at molecular weights of 95 Kd, 55 Kd and 33 Kd. Fibrin binding of u-PA was observed at molecular weights of 55 Kd and 33 Kd.

Clinical trials of recombinant biologic agents have resulted in new treatment options for hematologic, oncologic, and cardiologic disorders. These agents include the interferons, recombinant human erythropoietin (r-HuEPO), colony-stimulating factors (CSFs), interleukins (ILs), and tissue plasminogen activator (t-PA). Interferon alfa has proven efficacious in treating certain hematologic malignancies and solid tumors and has recently been indicated for acquired immunodeficiency syndrome (AIDS)-related Kaposi's sarcoma. Treatment with r-HuEPO has relieved the chronic anemia of hemodialysis patients. Recombinant human granulocyte CSF (G-CSF) or human granulocyte macrophage CSF (GM-CSF) has been used to treat patients after autologous bone marrow transplantation for lymphoid or solid malignancies, resulting in increased production of granulocytes and platelets. G-CSF and GM-CSF have been used to treat aplastic anemia, myelodysplastic syndromes, chemotherapy-induced neutropenia, and neutropenia associated with AIDS. In patients with evolving myocardial infarction, the recombinant agent t-PA has proved more efficacious than streptokinase in terms of average coronary artery patency rates and survival rates in patients with evolving myocardial infarction. While these agents all offer promising therapeutic advances, the expenses associated with developing and testing biotherapeutic substances have resulted in high treatment costs. Since in many instances investigational therapy is the best treatment option available, physicians, patients, the pharmaceutical industry, the government, and insurance carriers must work together to ensure that these therapies are financially available to those in need.

There are few reports about the occurrence of hepatic VOD after BMT for severe aplastic anemia (SAA). We prospectively studied 17 patients with SAA after allogeneic BMT for the occurrence and severity of VOD. Plasma levels of protein C, protein S, antithrombin III, vWF, t-PA and PAI-1 were determined before preparative chemotherapy, on the day of marrow infusion, and on days 7, 14 and 21. VOD occurred in seven patients (41.2%) at a median of day 1 (range, day -2 to 15). Five had mild, and two moderate VOD. Platelet transfusion requirements were higher in the patients with VOD. The plasma levels of natural anticoagulants such as protein C, free protein S and antithrombin III decreased significantly on day 0 from the baseline levels. Plasma levels of t-PA, PAI-1 and vWF increased significantly in the early post-transplant period compared to the baseline levels. The mean plasma levels of t-PA on day 7 (P = 0.016) and PAI-1 on days 0 and 7 (P = 0.016, 0.032) were higher in the patients with VOD. In summary, we observed hypercoagulability and a high incidence of VOD after allogeneic BMT for SAA. Levels of t-PA and PAI-1 were significantly higher in the patients with VOD after BMT.
