Background: There is a high incidence of systemic embolism in patients with chronic atrial fibrillation. A hypercoagulable state has been demonstrated, but the fibrinolytic system is rarely studied.
Methods: Plasma levels of modified antithrombin III (ATM), tissue plasminogen activator (TPA), its inhibitor (PAI-1), TPA-PAI-1 complexes and plasmin-antiplasmin complexes (PAP), d -dimer, and fibrinogen were measured in plasma from 36 patients with chronic atrial fibrillation.
Introduction: There are many differences between fetal and adult erythropoiesis, but in both cases erythropoietin (EPO) is the critical controlling haemopoiesis. EPO can be measured in fetal blood by the 16th gestational week, and its levels show a gradual rise to term in parallel with the rise in haemoglobin levels. The aim of this study was to determine EPO levels in normal newborns and correlate them with the delivery, maternal EPO and pregnancy complications.

We also analyzed the influence of the antithrombotic therapy on the fibrinolysis's proteins.
Patients And Methods: We included 18 patients, stratified in two etiologic groups: 9 with idiopathic and 9 with ethyl DCM.
Purpose: To discover the prevalence of antiphospholipid antibodies in women with a history of repeated miscarriages. Therapy evaluation of aspirin and prednisone to achieve living term foetus from women in whom antiphospholipid antibodies had been detected and who had become pregnant again.
Patients And Methods: 82 consecutive women with history of at least of two miscarriages, with no live foetus in either case.
