13. Coagulation activation in autoimmune bullous diseases
The main autoimmune blistering skin disorders are pemphigus vulgaris (PV) and bullous pemphigoid (BP). They differ in the inflammatory infiltrate, which is more intense in BP. Inflammation is known to activate coagulation in several disorders. Local and systemic activation of coagulation was evaluated in BP and PV. We studied 20 BP patients (10 active and 10

14. A puerperal haemorrhagic state due to a heparin-like anticoagulant
The occurrence of a severe generalized haemorrhagic state in an obstetric case due to a heparin-like anticoagulant is described. This appeared in the post-partum period apparently following a compatible blood transfusion. The pattern of results found in conventional laboratory tests for elucidating acute blood coagulation disorders is described, and the dist

15. Spontaneous extradural haematomas.
Spontaneous extradural haemorrhage may be due to neighbourhood infections, vascular malformations of the dura mater, and disorders of blood coagulation. Two cases are described here: in one, infection was present; in the other, there was a berry aneurysm of the middle meningeal artery with a small parietal dural angioma. Operation was successful in both pati

16. In vitro generation of endothelial microparticles and possible prothrombotic activity in patients with lupus anticoagulant
Microparticles (MPs) resulting from vesiculation of platelets and other blood cells have been extensively documented in vitro and have been found in increased numbers in several vascular diseases, but little is known about MPs of endothelial origin. The aim of this study was to analyze morphological, immunological, and functional characteristics of MPs deriv

17. Intraepithelial haemorrhage of the oesophagus: a terminal event in haematological disorders.
AIMS: To investigate the clinicopathological findings in cases with intraepithelial haemorrhage of the oesophagus (IHO). METHODS: Necropsy records and the histopathology findings in the oesophagus were reviewed for the period 1990 to 1995. Six cases (0.7%) of IHO were found among 919 necropsy cases. Clinical records of these patients and gross and microscopi

18. Haematological stress syndrome in atherosclerosis.
Forty patients with atherosclerotic peripheral vascular disease, as compared to 29 healthy controls, showed a significant increase in platelet number and activity, a neutrophil leucocytosis, and a raised level of several acute-phase reactant proteins (fibrinogen, antithrombin III, factor VIII, and serum globulin). The hyperproteinaemia was associated with in

19. Role of shear rate and platelets in promoting fibrin formation on rabbit subendothelium. Studies utilizing patients with quantitative and qualitative platelet defects.
The deposition of platelets on subendothelium of rabbit aortic segments exposed to non-anticoagulated human blood increased progressively with increasing wall shear rates (50-2,600 s-1), whereas fibrin deposition decreased. Studies in normal subjects and patients with platelet disorders suggested that, under the conditions used, platelets were essential for

20. Role of Ebola Virus Secreted Glycoproteins and Virus-Like Particles in Activation of Human Macrophages
Ebola virus, a member of the family Filoviridae, causes one of the most severe forms of viral hemorrhagic fever. In the terminal stages of disease, symptoms progress to hypotension, coagulation disorders, and hemorrhages, and there is prominent involvement of the mononuclear phagocytic and reticuloendothelial systems. Cells of the mononuclear phagocytic syst
