| Nicolle's white mycetoma | Mycetoma caused by a species of Aspergillus, and producing relatively large granules, about the size of a pea; infection occurs from barley grain. (05 Mar 2000) |

| deep white layer of superior colliculus | See: gray layer of superior colliculus. (05 Mar 2000) |
| egg white | The white of an egg, especially a chicken's egg, used in cooking. It contains albumin. (12 Dec 1998) |
| egg-white injury | <syndrome> Dermatitis, loss of hair, and loss of muscle coordination, produced in rats by diets containing large amounts of raw egg white, the avidin of which combines with biotin producing a deficiency of the latter. Synonym: egg-white injury. (05 Mar 2000) |
| egg-white syndrome | <syndrome> Dermatitis, loss of hair, and loss of muscle coordination, produced in rats by diets containing large amounts of raw egg white, the avidin of which combines with biotin producing a deficiency of the latter. Synonym: egg-white injury. (05 Mar 2000) |
| familial white folded dysplasia | An autosomal dominant condition of the oral cavity characterised by soft, white or opalescent, thickened and corrugated folds of mucous membrane; other mucosal sites are occasionally involved simultaneously. Synonym: familial white folded dysplasia, oral epithelial nevus. (05 Mar 2000) |
| zinc white | <chemical> A mild astringent and topical protectant with some antiseptic action. It is also used in bandages, pastes, ointments, dental cements, and as a sunblock. Pharmacological action: dermatologic agents, sunscreening agents. Chemical name: Zinc oxide (ZnO) (12 Dec 1998) |
| Lee-White method | A method for determining coagulation time of venous blood in tubes of standard bore at body temperature. (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-air barrier | The barrier between capillary blood and alveolar air comprising the alveolar epithelium and capillary endothelium with their adherent basement membranes and epithelial cell cytoplasm. Gaseous exchange occurs across this membrane. (12 Dec 1998) |
