| anti-glomerular basement membrane disease | Glomerulonephritis, usually of a generalised proliferative crescent-forming histologic type with a rapidly progressive course, marked by circulating anti-gbm antibodies and linear deposits of immunoglobulin and complement along the glomerular basement membrane. When associated with pulmonary haemorrhage the condition is called goodpasture syndrome. (12 Dec 1998) |

| anti-basement membrane antibody | Autoantibodies to renal glomerular basement membrane antigens. (05 Mar 2000) |
| anti-basement membrane glomerulonephritis | Glomerulonephritis resulting from anti-basement membrane antibodies, characterised by smooth linear deposits of IgG and C3 along glomerular capillary walls; includes rapidly progressive glomerulonephritis and glomerulonephritis in Goodpasture's syndrome. (05 Mar 2000) |
| anti-basement membrane nephritis | Glomerulonephritis produced by autologous or heterologous antibodies to the glomerular capillary basement membranes, the latter known as anti-kidney serum nephritis. (05 Mar 2000) |
| basement membrane | <cell biology> Extracellular matrix characteristically found under epithelial cells. There are two distinct layers: the basal lamina, immediately adjacent to the cells, is a product of the epithelial cells themselves and contains collagen type IV and the reticular lamina is produced by fibroblasts of the underlying connective tissue and contains fibrillar collagen. (15 Nov 1997) |
| basement | The outer wall of the ground story of a building, or of a part of that story, when treated as a distinct substructure. (See Base, 3) Hence: The rooms of a ground floor, collectively. <anatomy> Basement membrane, a delicate membrane composed of a single layer of flat cells, forming the substratum upon which, in many organs, the epithelioid cells are disposed. Origin: F. Soubassement. Of uncertain origin. Cf. Base, Bastion. Source: Websters Dictionary (01 Mar 1998) |

| chromatography, thin layer | Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose. (12 Dec 1998) |
| thin | Not thickly or closely; in a seattered state; as, seed sown thin. "Spain is thin sown of people." (Bacon) 1. Having little thickness or extent from one surface to its opposite; as, a thin plate of metal; thin paper; a thin board; a thin covering. 2. Rare; not dense or thick; applied to fluids or soft mixtures; as, thin blood; thin broth; thin air. "In the day, when the air is more thin." (Bacon) "Satan, bowing low His gray dissimulation, disappeared, Into thin air diffused." (Milton) 3. Not close; not crowded; not filling the space; not having the individuals of which the thing is composed in a close or compact state; hence, not abundant; as, the trees of a forest are thin; the corn or grass is thin. "Ferrara is very large, but extremely thin of people." (Addison) 4. Not full or well grown; wanting in plumpness. "Seven thin ears . . . Blasted with the east wind." (Gen. Xli. 6) 5. Not stout; slim; slender; lean; gaunt; as, a person becomes thin by disease. 6. Wanting in body or volume; small; feeble; not full. "Thin, hollow sounds, and lamentable screams." (Dryden) 7. Slight; small; slender; flimsy; wanting substance or depth or force; superficial; inadequate; not sufficient for a covering; as, a thin disguise. "My tale is done, for my wit is but thin." (Chaucer) Thin is used in the formation of compounds which are mostly self-explaining; as, thin-faced, thin-lipped, thin-peopled, thin-shelled, and the like. Thin section. See Section. Origin: OE.

| thin filament | Filaments 7-9nm diameter attached to the Z discs of striated muscle, have opposite polarity in each half sarcomere. Built of F actin with associated tropomyosin and troponin. (18 Nov 1997) |
| thin film | <radiobiology> Plasmas are often used to deposit thin-film coatings on various materials. (09 Oct 1997) |
| thin layer chromatography | <technique> Chromatography using a thin layer of powdered medium on an inert sheet to support the stationary phase. Faster than paper chromatography, gives higher resolution and requires smaller samples. (18 Nov 1997) |
| thin-layer chromatography | Chromatography through a thin layer of cellulose or similar inert material supported on a glass or plastic plate. (05 Mar 2000) |
| thin-layer electrophoresis | Electrophoretic migrations (separations) through a thin layer of inert material, such as cellulose, supported on a glass or plastic plate. (05 Mar 2000) |
| thin-layer immunoassay | A method for detection of antigen-antibody reactions, applicable to detection of either antigen or antibody, based on the fact that either reactant, when added to a polystyrene surface (such as a well in a polystyrene plate) is adsorbed as a thin layer and acts as an immunosorbent capable of binding with the second reactant.
