| 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 | <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 proteins | <dentistry> The proteins that are part of the dental enamel matrix. (12 Dec 1998) |
| capillary permeability | Property of blood capillary walls that allows for the selective exchange of substances. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (tight junctions) which may limit large molecule movement. (12 Dec 1998) |
| capillary permeability factor | A mixture of bioflavonoids extracted from plants (especially citrus fruits). It reduces the permeability and fragility of capillaries and is useful in the treatment of certain cases of purpura that are resistant to vitamin C therapy. See: hesperidin, quercetin, rutin. Synonym: capillary permeability factor, citrin, permeability vitamin. (05 Mar 2000) |
| cell membrane permeability | A quality of cell membranes which permits the passage of solvents and solutes into and out of cells. (12 Dec 1998) |
| permeability | The property or state of being permeable. (18 Nov 1997) |
| permeability coefficient | A coefficient associated with simple diffusion through a membrane that is proportional to the partition coefficient and the diffusion coefficient and inversely proportional to membrane thickness. (05 Mar 2000) |
| permeability constant | A measure of the ease with which an ion can cross a unit area of membrane driven by a 1.0 m difference in concentration; usually expressed in centimeters per second. Compare: permeability coefficient. (05 Mar 2000) |
| permeability theory of narcosis | That the permeability of the cell membrane is decreased by narcotic concentrations of aliphatic and other central nervous system depressants. (05 Mar 2000) |
| permeability vitamin | A mixture of bioflavonoids extracted from plants (especially citrus fruits). It reduces the permeability and fragility of capillaries and is useful in the treatment of certain cases of purpura that are resistant to vitamin C therapy. See: hesperidin, quercetin, rutin. Synonym: capillary permeability factor, citrin, permeability vitamin. (05 Mar 2000) |
| soil permeability | The ease with which gases, liquids or plant roots penetrate or pass through a layer of soil. (09 Oct 1997) |
| dentin permeability | The property of dentin that permits passage of light, heat, cold, and chemical substances. It does not include penetration by microorganisms. (12 Dec 1998) |
| Duran-Reynals permeability factor | <enzyme> Enzyme that degrades hyaluronic acid, found in lysosomes. (18 Nov 1997) |
| lymph node permeability factor | A substance, released by lymphocytes when stimulated or damaged, that increases capillary permeability and the accumulation of mononuclear cells. (05 Mar 2000) |
