| cohesive gold | Nearly pure gold so treated as to be free of adsorbed surface gases and impurities so that it will weld under pressure at room temperature; in dentistry, used as a restorative material placed directly into a prepared cavity and welded by pressure. (05 Mar 2000) |
|---|---|
| colloidal gold reaction | A test (now obsolete) based on precipitation of cerebrospinal fluid protein when mixed with colloidal gold. Abnormalities in this reaction were observed in patients with syphilis, multiple sclerosis, poliomyelitis, and encephalitis. (05 Mar 2000) |
| colloidal radioactive gold | A radioactive isotope of gold emitting negative beta particles and gamma radiation, with a half-life of 2.7 days; formerly used for irradiation of closed serous cavities in the palliative treatment of ascites and pleural effusion due to metastatic malignancies, and for liver scans. Synonym: 198Au colloid, colloidal radioactive gold. (05 Mar 2000) |
| powdered gold | Gold formed by atomizing or by chemical precipitation, lightly precondensed, and wrapped with gold foil so as to form pellets. (05 Mar 2000) |
| noncohesive gold | Gold that will not weld because gases adsorb to the surface; some forms may be made cohesive by heat treatment; in dentistry, used as a direct filling material. (05 Mar 2000) |
| airway resistance | The opposition of the tracheobronchial tree to air flow: the mouth-to-alveoli pressure difference divided by the air flow. (12 Dec 1998) |
| ampicillin resistance | Nonsusceptibility of a microbe to the action of ampicillin, a penicillin derivative that interferes with cell wall synthesis. (12 Dec 1998) |
| androgen resistance syndromes | A class of disorders associated with 5a-steroid reductase deficiency, testicular feminization, and related disorders. Compare: steroid 5a-reductase, Reifenstein's syndrome, infertile male syndrome, testicular feminization syndrome. (05 Mar 2000) |
| antibiotic resistance | The ability of a bacterium tosynthesise a protein that neutralises an antibiotic. (09 Oct 1997) |
| antibiotic resistance gene | Genes in a microorganism which confer resistance to antibiotics, for example by coding for enzymes which destroy it, by coding for surface proteins which prevent it from entering the microorganism, or by being a mutant form of the antibiotic's target so that it can ignore it. (09 Oct 1997) |
| bacteriophage resistance | Resistance of a bacterial mutant to infection by a bacteriophage to which the parent (wild type) strain is susceptible. (05 Mar 2000) |
| beta-lactam resistance | Nonsusceptibility of an organism to the action of the beta-lactam antibiotics. (12 Dec 1998) |
| capillary resistance | The resistance offered to the flow of blood through the capillary portion of the peripheral vascular bed. (12 Dec 1998) |
| capillary resistance test | A tourniquet test used to determine presence of vitamin C deficiency or thrombocytopenia; a circle 2.5 cm in diameter, the upper edge of which is 4 cm below the crease of the elbow, is drawn on the inner aspect of the forearm, pressure midway between the systolic and diastolic blood pressure is applied above the elbow for 15 minutes, and a count of petechiae within the circle is made: 10, normal; 10 to 20, marginal zone; over 20, abnormal. See: Rumpel-Leede test. Synonym: capillary resistance test, vitamin C test. (05 Mar 2000) |
| vascular resistance | An expression of the resistance offered by the systemic arterioles, and to a lesser extent by the capillaries, to the flow of blood. (12 Dec 1998) |
