| dura mater of brain | The intracranial dura mater, consisting of two layers: the outer periosteal layer which normally always adheres to the periosteum of the bones of the cranial vault; and the inner meningeal layer which in most places is fused with the outer. The two layers separate to accommodate meningeal vessels and large venous (dural) sinuses. The meningeal layer is also involved in the formation of the various dural folds, such as the falx cerebri and tentorium cerebelli and is comparable to and continuous with the dural mater of the spinal cord. The cranial epidural space is then a potential space between the bone and the combined periosteum/periosteal layer of the dura mater realised only pathologically and is neither continuous with or comparable to the vertebral epidural space. Synonym: dura mater cranialis, dura mater encephali, cerebral part of dura mater, cranial epidural space. (05 Mar 2000) |

| infantile brain tumours | <radiology> Can be present at birth: choroid plexus papilloma, medulloblastoma, craniopharyngioma, ependymoma, astrocytoma, teratoma (12 Dec 1998) |
| organic brain syndrome | <syndrome> A constellation of behavioural or psychological signs and symptoms including problems with attention, concentration, memory, confusion, anxiety, and depression caused by transient or permanent dysfunction of the brain. Synonym: acute organic brain syndrome, OBS, organic mental syndrome. (05 Mar 2000) |
| enhancing brain nodule | <radiology> Metastases, infection, cysticercosis, histoplasmosis, tuberculosis, non-infectious inflammatory processes, sarcoidosis, multiple sclerosis, primary CNS lymphoma, subacute multiple infarcts see: ring lesions in brain (12 Dec 1998) |
| twixt-brain | <anatomy> The thalamencephalon. Source: Websters Dictionary (01 Mar 1998) |
| lateral fossa of brain | The deep depression of the basal surface of the forebrain that corresponds in position to the anterior perforated substance. Bounded medially by the optic tract and rostrally by the orbital surface of the frontal lobe, it extends laterally around the overhanging pole of the temporal lobe into the Sylvian fissure (sulcus lateralis). Synonym: fossa lateralis cerebri, fossa of Sylvius, lateral fossa of brain, vallecula sylvii. (05 Mar 2000) |
| ABO blood group | <haematology> The major human blood type system which describes the oligosaccharide glycoprotein antigens found on the surface of human blood cells. According to the type of antigen present, a person may be assigned a blood type of A, B, AB or O. A second type of antigen, the Rh factor, renders a positive or negative blood type. The ABO blood group system is important because it determines who can donate blood to or accept blood from whom. Type A or AB blood will cause an immune reaction in people with type B blood and type B and AB blood will cause a reaction in people with type A blood. Conversely, type O blood has no A or B antigens, so people with type O blood are universal donors. And since AB blood already produces both antigens, people who are type AB can accept any of the other blood types without suffering an immune reaction. (04 Jul 1999) |
| Almen's test for blood | Glacial acetic acid, gum guaiac solution, and hydrogen peroxide are added to an aqueous suspension of the suspected stain; if occult blood or blood pigment is present, a blue colour develops. Synonym: guaiac test, Schonbein's test, van Deen's test. (05 Mar 2000) |
| arterial blood | Blood that is oxygenated in the lungs, found in the left chambers of the heart and in the arteries, and relatively bright red. (05 Mar 2000) |
| arterial blood gas | A test which analyses arterial blood for oxygen, carbon dioxide and bicarbonate content in addition to blood pH. Used to test the effectiveness of respiration. Acronym: ABG (17 Oct 1997) |
| blood | <haematology> Considered a circulating tissue composed of a fluid portion (plasma) with suspended formed elements (red blood cells, white blood cells, platelets). Arterial blood is the means by which oxygen and nutrients are transported to tissues, venous blood is the means by which carbon dioxide and metabolic by-products are transported for excretion. (05 Jan 1998) |
| blood agar | <cell culture> An agar-based medium which hasbeen enriched with sterilised, defibinated blood (sheep, rabbit or horse). It is used for primary plating andsubculturing, especially to determine bacterial haemolysis. (09 Oct 1997) |
| blood albumin | <protein> The serum level of the low molecular protein albumin. Albumin, produced by the liver, plays an important role in maintaining plasma oncotic pressure. Normal serum albumin should be 3.5-5.0 grams per decilitre. Low serum albumin can be found in cases of liver disease and malnutrition. (27 Sep 1997) |
| blood bactericidal activity | Native bactericidal property of blood due to normally occurring antibacterial substances such as beta lysin, leukin, etc. (12 Dec 1998) |
| blood bank | A place, usually a separate part or division of a hospital laboratory or a separtate free-standing facility, in which blood is collected from donors, typed, separated into several components, stored, and/or prepared for transfusion to recipients. (05 Mar 2000) |
