In inflammatory demyelinating diseases such as multiple sclerosis and experimental allergic encephalomyelitis, myelin destruction occurs in the vicinity of infiltrating mononuclear cells. The observations that myelin can be altered prior to phagocytosis and in areas not contiguous with inflammatory cells suggests a common mechanism for the initial stages of demyelination. Because stimulated mac...

The fibrinolytic system may play a role in the pathogenesis of coronary heart disease (CHD), but existing prospective studies have not consistently shown an independent association between fibrinolytic factors and CHD. None has reported an association between plasminogen and CHD incidence. In the prospective Atherosclerosis Risk in Communities (ARIC) Study of middle-aged adults, we examined the...

The aim of the study is to assess the diagnostic accuracy of some fibrinolytic parameters in the differential diagnosis between patients with unstable angina (UA) and musculoskeletal disorders (MSD). Methods. This cross-sectional study included 119 patients with chest pain (CP) and provisional diagnosis “UA”. After a full set of diagnostic procedures, authors formed 4 groups: patients with isc...

Glucocorticoids induce several phenotypic changes in rat hepatoma cells in tissue culture, including the inhibition of plasminogen activator activity. Variant cell lines resistant to dexamethasone inhibition of plasminogen activator activity have been isolated using an agar-fibrin overlay technique to identify colonies with fibrinolytic (plasminogen activator) activity. The variants are resista...

BACKGROUND AND PURPOSE We studied the activities of the coagulation-fibrinolysis system in the chronic stage of poststroke patients and the effect of antiplatelet medication on the system. METHODS We determined fibrinogen, antithrombin III, thrombin-antithrombin III complex, tissue plasminogen activator antigen, plasminogen activator inhibitor-1, plasmin-alpha 2 plasmin inhibitor complex, and...

Hemostasis abnormalities have been described in patients with Mediterranean spotted fever and Rocky Mountain spotted fever. Evidence of the activation of the fibrinolytic system has been obtained in both diseases. After experimental Rocky Mountain spotted fever, an elevated level of fibrinogen was found in parallel with the activation of the fibrinolytic system and transient elevation of the ti...

The ZNF198/FGFR1 fusion kinase associated with an atypical myeloproliferative disease is constitutively activated and regulates several STAT transcription factors. We used oligonucleotide microarrays to compare the gene-expression profiles between HEK-293 cells that stably express either the ZNF198/FGFR1 chimeric protein or the wild-type ZNF198 gene. Expression of the plasminogen activator inhi...

Plasma samples from patients with alcoholic cirrhosis were analysed for plasminogen activators and for inhibitors of the fibrinolytic system. Plasminogen activator activity was considerably increased in patients' plasma compared with normal. Immunochemical characterisation of these plasminogen activators showed that they included both tissue type and urokinase type plasminogen activator. The ma...

A vascular plasminogen activator obtained by perfusion of the vessels of the lower extremities of human cadavers has been purified to apparent homogeneity by sequential precipitation in ammonium sulfate, reverse ammonium sulfate gradient solubilization, hydrophobic chromatography on octyl-Sepharose, and gel filtration on Sephadex G-75 and G-150. The isolation procedures were carried out in the ...
