BACKGROUND Pathogenesis of intraventricular hemorrhage (IVH) in premature infants is multifactorial. Little is known about the influence of pro-inflammatory cytokine activation on the coagulation system in extremely preterm infants and its impact on the development of IVH. OBJECTIVE To determine the interaction between serum interleukin-6 (IL-6) and the coagulation system in preterm infants p...

BACKGROUND Development of hydroxyethyl starches (HES) with a low impact on blood coagulation but a long intravascular persistence is of clinical interest. A previous in vitro study showed that low substituted high molecular weight HES does not compromise blood coagulation more than medium molecular weight HES. In the present study we assessed the individual effects on blood coagulation of molar...

Serial studies on coagulation factors were performed on 12 patients having termination of mid-trimester pregnancy by extra-amniotic prostaglandin F(2)alpha and 11 patients terminated by vacuum aspiration during the first trimester. A significant change in the activity of factors V, VII and X, VIII, and X, and a decrease of the prothrombin time and platelet count were found with prostaglandin te...

We describe a family with an autosomal dominant disorder characterized by severe trauma- and surgery-related bleeding. The proband, who experienced life-threatening bleeding during a routine operation, had normal clotting times, but markedly reduced prothrombin consumption. Plasma levels of all coagulation factors and of the main coagulation inhibitors were normal. Thrombin generation at low tr...

Background and Aims: Fresh Frozen Plasma (FFP) is one of blood components. The risk of transmission of viruses from blood components regardless selection of blood donors and screening donated blood still remains. There are several methods for viral inactivation. In this study methylene blue (MB) photo inactivation process was used for inactivating viruses. Materials and Methods: In this study M...

Hemophilia is an inherited blood clotting disorder resulting from deficiency of blood coagulation factors. Current standard of care for hemophilia patients is frequent intravenous infusions of the missing coagulation factor. Gene therapy for hemophilia involves the introduction of a normal copy of the deficient coagulation factor gene thereby potentially offering a definitive cure for the bleed...

Pregnancy induces complex changes concerned with hemostasis. Normal pregnancy is associated with hypercoagulable state which becomes more pronounced at term while in pre-eclampsia or pregnancyinduced hypertension (PIH), localized coagulation fibrinolytic imbalance has been reported(l,2). Various coagulation factors are decreased in concentration in PIH, especially fibrinogen, factor V, VII, VII...

The major goal in the development of new anticoagulant drugs is a more effective action with less adverse effects. Until now the mainly used agents are heparin and phenprocoumon or warfarin. These drugs inhibit multiple coagulation factors in different stages of the coagulation cascade. Modern drug development and the knowledge about the molecular mechanisms of the coagulation cascade allow spe...

The immunohistochemical distribution of 15 blood coagulation factors in the germinal centers (GCs) of human Peyer's patches (PPs) was studied. Although factor VIII, active alpha-thrombin, and fibrinogen were hardly evident in the GCs, the majority of coagulation factors, such as kallikrein, high-molecular-weight kininogen, factors XII, X, IX, VII, V, XIIIa and XIIIb, prothrombin, anti-thrombin ...
