| isotonic traction | Traction in which the amount of force does not change. (05 Mar 2000) |
|---|---|
| traction | <dentistry> The act of drawing or pulling the teeth. (08 Jan 1998) |
| traction alopecia | Circumscribed or diffuse loss of hair resulting from repetitive traction on the hair by pulling or twisting; also occurs after excessive application of hair "softeners" such as permanent wave solutions or hot combs. Alopecia marginalis is a form of traction alopecia. Synonym: traumatic alopecia. (05 Mar 2000) |
| traction atrophy | Bands of thin wrinkled skin, initially red but becoming purple and white, which occur commonly on the abdomen, buttocks, and thighs at puberty and/or during and following pregnancy, and result from atrophy of the dermis and overextension of the skin; also associated with ascites and Cushing's syndrome. Synonym: atrophoderma striatum, lineae albicantes, lineae atrophicae, linear atrophy, stretch marks, stria, striae atrophicae, striate atrophy of skin, traction atrophy, vergeture. (05 Mar 2000) |
| traction diverticulum | A diverticulum formed by the pulling force of contracting bands of adhesion, occurring mainly in the distal oesophagus, from tuberculous hilar or mediastinal lymphadenitis. (05 Mar 2000) |
| traction epiphysis | A secondary centre of ossification at the site of attachment of a tendon. (05 Mar 2000) |
| external traction | A pulling force created by using fixed anchorage (e.g., a headcap or bed frame) outside the oral cavity; principally used in the management of midfacial fractures. (05 Mar 2000) |
| extraoral traction appliances | Extraoral devices for applying force to the dentition in order to avoid some of the problems in anchorage control met with in intermaxillary traction and to apply force in directions not otherwise possible. (12 Dec 1998) |
| accelerated reaction | A response occurring in a shorter time than expected; the cutaneous manifestations occurring during the period between the second and tenth day following smallpox vaccination; because it is intermediate between a primary reaction and an immediate reaction, it is regarded as evidence of some degree of resistance. Synonym: vaccinoid reaction. (05 Mar 2000) |
| acid reaction | Any test by which an acid reaction is recognised such as the change of blue litmus paper to red, an excess of hydrogen ions over hydroxide ions in aqueous solution indicated by a pH value less than 7 (at 22캜). Compare: dissociation constant of water. (05 Mar 2000) |
| acute-phase reaction | <immunology, rheumatology> Refers to the changes in synthesis of certain proteins within the serum during an inflammatory response, which provides rapid protection for the host against microorganisms via non-specific defense mechanisms. It consists of fever, an increase in inflammatory humoral factors, and an increased synthesis by hepatocytes of a number of proteins or glycoproteins usually found in the plasma; the reaction is mediated by endogenous pyrogens, the hypothalamus, adrenal hormones, and other factors. (12 Jul 2000) |
| acute situational reaction | An acute emotional reaction related to extreme environmental stress. Synonym: acute situational reaction. (05 Mar 2000) |
| acute stress reaction | A sudden bout of anxiety that is often accompanied by the features of hyperventilation (tingling around mouth and in fingertips, rapid breathing, faintness or fainting). (27 Sep 1997) |
| addition reaction | <chemistry> Any reaction in which two chemicals combine to form a single chemical. (15 Jan 1998) |
| adverse drug reaction reporting systems | Systems developed for collecting reports from government agencies, manufacturers, hospitals, physicians, and other sources on adverse drug reactions. (12 Dec 1998) |
