This randomized, multicenter clinical trial enrolled 103 children hospitalized with septated parapneumonic empyema (PPE) who were randomized to receive thoracoscopy (n=53) or urokinase (n=50). The main outcome variable was the length of hospital stay after treatment. The secondary outcomes were total length of hospital stay, number of days with the chest drain, number of days with fever, and tr...

The anti-urokinase-IgG-resistant plasminogen activator secreted by human embryonic lung diploid fibroblasts, IMR-90 cells (ATCC, CCL186) was purified to homogeneity from serum-free conditioned medium by a four-step procedure. The fibroblast plasminogen activator was identified as tissue plasminogen activator (t-PA) by the N-terminal sequence of the purified material and the complete amino acid ...

PURPOSE Prostate cancer cell motility and invasion have been linked to the up-regulated signaling of epidermal growth factor receptor and urokinase-type plasminogen activator receptor. We analyzed the expression of serum urokinase-type plasminogen activator receptor and epidermal growth factor receptor in the serum of patients with clinical suspicion of prostate cancer to evaluate the possible ...

We have recently found a novel fatty acid, 11-keto-9(E),12(E)-octadecadienoic acid (KOD), that enhances fibrinolytic activity of endothelial cells. The mechanism of action of KOD has been investigated. KOD increased 2-fold the plasmin activity of bovine aortic endothelial cells at 250 microM. The stimulation was dependent on plasminogen and was inhibited by anti-urokinase, whereas KOD did not e...

Aim: The urokinase-type plasminogen activator (uPA) system consists of a protease, receptor (urokinase-type receptor, uPAR), and inhibitors that can be expressed on various cell types. Previous literature shows the amount soluble (suPAR) secreted from affected cells is higher in Crimean-Congo hemorrhagic fever (CCHF) patients than healthy controls. Thus, we aimed to investigate diagnostic value...

To investigate the effect of MMP-9, MMP-2 and vWF in patients with low doses of urokinase peritoneal dialysis decreased uremia complicated with cerebral infarction. 112 cases of uremia complicated with cerebral infarction were randomly divided into the peritoneal dialysate with urokinase treatment group (66 cases) and the conventional treatment group (46 cases). At the same time, 50 cases of he...

It was confirmed by zymographic technique that 1 ml of normal human plasma possessed about 0. 2 IU of urokinase activity which is a high molecular weight form with a molecular weight of 53, 000. Plasma of an acute pancreatitis patient followed by disseminated intravascular coagulation possessed the same amount of urokinase activity as normal plasma, and was confirmed to be composed of two types...

Streptokinase and urokinase have proved to be useful in a limited number of clinical conditions. Mainly because of the risk and unpredictability of bleeding with this first generation of thrombolytic agents, thrombolysis has not been ingrained in medical practice. In the interim, more fibrin-specific thrombolytic agents have been developed such as acylated streptokinase-human plasminogen comple...
