| Hines-Brown test | A cardiocirculatory challenge conventionally performed by immersing one hand in ice cold water for two or more minutes (as tolerated) to acutely raise the blood pressure, thus imposing resistance to ejection of blood from the left ventricle into the systemic arterial system and consequently acutely increased afterload (afterload = increased left ventricular wall stress). Synonym: Hines-Brown test. (05 Mar 2000) |

| Sudan brown | A brown stain, (C10H7)N==N(C10H6)OH, derived from alpha-naphthylamine and used as a stain for fats. (05 Mar 2000) |
| syndrome, brown's | An ophthalmology (eye) problem. Brown's syndrome presents at birth (congenitally) and is characterised by an inability to elevate the eyeball when also trying to move the eyeball to the outside. (12 Dec 1998) |
| reduced enamel epithelium | The several layers of the enamel organ remaining on the enamel surface after formation of enamel is completed. Synonym: reduced enamel epithelium. (05 Mar 2000) |
| mottled enamel | Alterations in enamel structure due to excessive fluoride ingestion during tooth formation; varies in appearance from small white opacities to yellow and black spotting. Nanoid enamel, a condition of abnormal thinness of the enamel. Synonym: dwarfed enamel. Whorled enamel, enamel in which the rods assume a spiral or twisting course. (05 Mar 2000) |
| dental enamel | <dentistry> A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath. (12 Dec 1998) |
| dental enamel hypoplasia | <dentistry> A form of amelogenesis imperfecta characterised by incomplete formation of the dental enamel and transmitted as an x-linked or autosomal dominant trait. It is also associated with vitamin a, c, or d deficiency, infectious disease, prematurity, birth injury, rh incompatibility, trauma, or local infection. Small grooves, pits, and fissures are seen in mild cases, deep horizontal rows of pits in severe cases, or absence of enamel in extreme cases. (12 Dec 1998) |
| dental enamel permeability | <dentistry> The property of dental enamel to permit passage of light, heat, gases, liquids, metabolites, mineral ions and other substances. It does not include the penetration of the dental enamel by microorganisms. (12 Dec 1998) |
| dental enamel proteins | <dentistry> The proteins that are part of the dental enamel matrix. (12 Dec 1998) |
| dwarfed enamel | nanoid enamel |
| enamel | <dentistry> A hard ceramic which covers the exposed part of your teeth. (08 Jan 1998) |
| enamel cap | The enamel covering the crown of a tooth. (05 Mar 2000) |
| enamel cell | <cell biology> Columnar epithelial cells that secrete the enamel layer of teeth in mammals. Their apical surfaces are tapering Tomes processes) and are embedded within the enamel matrix. (18 Nov 1997) |
| enamel cleavage | The splitting of enamel in a plane parallel to the direction of the enamel rods. (05 Mar 2000) |
| enamel cleaver | An instrument with a heavy shank and a very short blade at about 90 |
