| cell membrane permeability | A quality of cell membranes which permits the passage of solvents and solutes into and out of cells. (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) |
| 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) |
| 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) |
| 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) |
| cell membrane | <cell biology> The structure enveloping a cell, enclosing the cytoplasm and forming a selective permeability barrier. It consists of lipids, proteins and some carbohydrates, the lipids thought to form a bilayer in which integral proteins are embedded to varying degrees. Synonym: plasma membrane. (26 Mar 1998) |
| coated pits, cell-membrane | Specialised regions of the cell membrane composed of pits coated with a bristle covering made of the protein clathrin. These pits are the entry route for macromolecules bound by cell surface receptors. The pits are then internalised into the cytoplasm to form the coated vesicles. (12 Dec 1998) |
| T-cell-rich, B-cell lymphoma | <tumour> A B-cell lymphoma in which more than 90% of the cells are of T-cell origin, masking the large cells that form the neoplastic B-cell component. See: adult T-cell lymphoma. (05 Mar 2000) |
