Haemorrhagic diathesis of the newborn is usually characterized by a physiological deficiency of prothrombin and probably also by a deficiency of proconvertin (van Creveld, Paulssen, Ens, Mey, Versteegh and Versteeg, 1954). Sometimes a third clotting-factor, pro-accelerin, is also lacking. We found a simultaneous deficiency both of prothrombin and pro-accelerin in some cases of intra-uterine mel...

Derangement of the blood clotting system contributes strongly to multiple organ failure in severe sepsis. In this review, we examine two microbial modulators of the clotting system: polyphosphates and omptins. Polyphosphates are linear polymers of inorganic phosphate that are abundant in the acidocalcisomes of prokaryotes and unicellular organisms as well as in the dense granules of human plate...

Water, as one of the main sources life, is an important aspect to public health and safety. Up until now there have been many concerns about water pollution especially in developing countries. Heavy polluted that not treated well could cause concerning diseases can lead deaths. Contaminants are chemical, physical, biological origins commonly found these sources. Gram negative bacteria (GNB) see...

A 65 year old patient who was exposed to topical bovine thrombin during cardiac surgery developed markedly prolonged clotting times and a severe bleeding diathesis. Mixing studies with normal plasma failed to correct the clotting times. Platelet transfusions, immunosuppressive and immunomodulatory therapies were ineffective, but plasmapheresis was effective in decreasing clotting times and in t...

Combined deficiency of vitamin K-dependent clotting factors II, VII, IX and X (and proteins C, S, and Z) is usually an acquired clinical problem, often resulting from liver disease, malabsorption, or warfarin overdose. A rare inherited form of defective gamma-carboxylation resulting in early onset of bleeding was first described by McMillan and Roberts in 1966 and subsequently has been termed '...

BACKGROUND AND AIMS Epidemiology studies have shown that cardiovascular (CV) disease is primarily responsible for the mortality associated with increased pulmonary environmental particle (PM10) exposure. The mechanisms involved in PM10 mediated CV effects are unknown although changes in plasma viscosity and in the homoeostasis of blood coagulation have been implicated. It was hypothesised that ...

Objective(s): Haemostasis prevents blood loss following vascular injury. It depends on the unique concert of events involving platelets and specific blood proteins, known as coagulation factors. The clotting system requires precise regulation and coordinated reactions to maintain the integrity of the vasculature. Clotting insufficiency mostly occurs due to genetically inherited coagulation fact...

Bleeding times were performed on 71 hemophiliacs using the Simplate II device. Eight patients receiving Indocin or Motrin for hemophilic arthropathy were evaluated separately from the remaining 63 who had a mean bleeding time of 7.65 +/- 3.20 min (1 SD) compared to the control group of 5.35 +/- 1.49 min (p less than 0.005). No difference was found when 26 mild hemophiliacs who had received less...

OBJECTIVE For skin defects caused by full-thickness burns, trauma, or tumor tissue excision, skin grafting is one of the most convenient and useful treatment methods. In this situation, graft fixation is important in skin grafting. This study was performed to compare the effectiveness of skin graft fixation between high-concentration fibrin sealant and sutures. There have been numerous studies ...
