| insecticide, organochlorine | A class of insecticide composed of chlorinated organic compounds. (12 Dec 1998) |
| insecticide, organophosphate | A class of insecticide composed of an organic radical bound to a phosphorus-containing radical. (12 Dec 1998) |
| insecticide, organothiophosphate | A class of insecticide composed of an organic radical bound to a thiophosphorus acid radical. One or more of the oxygen atoms of the phosphorus acid radical may be replaced by one or more sulfur atoms. (12 Dec 1998) |
| 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) |

| 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) |
