| haemopericardium | <cardiology> A collection of blood in the pericardial sac surrounding the heart. (27 Sep 1997) |
| haemoperitoneum | An effusion of blood in the peritoneal cavity. (12 Dec 1998) |
| haemopexin | <protein> Single chain haem binding plasma _1 glycoprotein (57 kD) unlike haptoglobin does not bind haemoglobin. Present at around 1mg/ml in plasma. Responsible for transporting haem groups to the liver for breakdown. Structurally related to vitronectin and some collagenases. (18 Nov 1997) |

| haemophagocyte | <haematology> A phagocyte which destroys blood cells. (16 Dec 1997) |
| haemophagocytosis | The process of engulfment (and usually destruction) of blood cells by the various types of phagocytic cells; used especially with reference to the engulfment of erythrocytes and others of the erythroid series. (05 Mar 2000) |

| haemophilia | <disease, haematology> A haemorrhagic diathesis occurring in two main forms: 1. Haemophilia A (classic haemophilia, factor VIII deficiency), an X linked disorder due to deficiency of coagulation factor VIII. 2. Haemophilia B (factor IX deficiency, Christmas disease), also X linked, due to deficiency of coagulation factor IX. Both forms are determined by a mutant gene near the telomere of the long arm of the X chromosome (Xq), but a different loci and are characterised by subcutaneous and intramuscular haemorrhages, bleeding from the mouth, gums, lips and tongue, haematuria and haemarthroses. (18 Nov 1997) |
| haemophilia A | <haematology> A sex-linked genetic disease affecting males that results from a deficiency of clotting factor VIII, a protein factor that is required for normal blood coagulation. Symptoms include easy bruising, bleeding gums, nosebleeds and bleeding into muscle tissue (haematoma) or a joint space (haemarthrosis). Treatment includes the infusion of factor VIII concentrate intravenously to restore this essential factor and normalize blood coagulation. Inheritance: sex-linked. (27 Sep 1997) |
| haemophilia B | <haematology> A form of haemophilia in males that results from a deficiency of clotting factor IX, transmitted as a X-linked trait. Symptoms include easy bruising, nosebleeds, bleeding gums and bleeding into muscle tissue (haematoma) or a joint space (haemarthrosis). Treatment includes the infusion of factor IX concentrates to normalize blood coagulation. Inheritance: sex-linked. (27 Sep 1997) |
| haemophilia C | <haematology> A patient afflicted with a sex-linked genetic disease affecting males that results from a deficiency of a specific protein factor that is required for normal blood coagulation. See: haemophilia A and haemophilia B. (27 Sep 1997) Previous: haemophagocytosis, haemophil, haemophilia, haemophilia A, haemophilia BNext: haemophilia C, haemophilic, haemophilic arthritis, haemophilic bacteriahaemophilia C <haematology> Haemophilia due to deficiency of factor XI; clinically resembles haemophilia A and B but has different inheritance. Inheritance: autosomal dominant. (20 Sep 2002) |
