| multiple chemical sensitivity | An acquired disorder characterised by recurrent symptoms, referable to multiple organ systems, occurring in response to demonstrable exposure to many chemically unrelated compounds at doses far below those established in the general population to cause harmful effects. No single widely accepted test of physiologic function can be shown to correlate with symptoms. (cullen mr. The worker with multiple chemical sensitivities: an overview. Occup med 1987;2(4):655-61) (12 Dec 1998) |
|---|---|
| mumps sensitivity test | A skin test for sensitivity to mumps, in which inactivated mumps virus is used as antigen. (05 Mar 2000) |
| contact sensitivity | Allergic response to contact with irritant, usually a hypersensitivity. (18 Nov 1997) |
| contrast sensitivity | The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease. (12 Dec 1998) |
| primaquine sensitivity | Nonimmunological inborn sensitivity to primaquine, causing haemolysis on exposure to the drug, due to deficiency of glucose-6-phosphate dehydrogenase in red cells. (05 Mar 2000) |
| salt sensitivity | The tendency of certain bacterial suspensions to agglutinate spontaneously in physiological saline solution. (05 Mar 2000) |
| sensitivity | <microscopy> Similar to responsively of an image pickup tube but numerically different. The signal current developed in an image pickup tube per unit incident radiation density (watt per unit area) or illuminance (lux on the faceplate). Unless otherwise specified, the radiation is understood to be that of an unfiltered incandescent source at 2854 or 2856[[macron]]K. (05 Aug 1998) |
| sensitivity and specificity | Measures for assessing the results of diagnostic and screening tests. Sensitivity represents the proportion of truly diseased persons in a screened population who are identified as being diseased by the test. It is a measure of the probability of correctly diagnosing a condition. Specificity is the proportion of truly nondiseased persons who are so identified by the screening test. It is a measure of the probability of correctly identifying a nondiseased person. (12 Dec 1998) |
| sensitivity training group | A group in which members seek to develop self-awareness and an understanding of group processes rather than to obtain therapy for an emotional disturbance. See: encounter group, personal growth laboratory. (05 Mar 2000) |
| sensitivity training groups | A group of people who meet in an unstructured setting to learn about themselves, interpersonal relationships, and group processes and about larger social systems. (12 Dec 1998) |
| spectral sensitivity | The reciprocal of the amount of monochromatic radiation that produces a fixed response. (05 Mar 2000) |
| diagnostic sensitivity | The probability (P) that, given the presence of disease (D), an abnormal test result (T) indicates the presence of disease; i.e., P(T/D). See: clinical sensitivity. (05 Mar 2000) |
| disk sensitivity method | A procedure for testing the relative effectiveness of various antibiotics; small disks of paper (or other suitable material) are impregnated with known, appropriate amounts of antibiotic, and then placed on the surface of semisolid medium that has been previously inoculated with the organism being tested; after suitable periods of incubation at 37캜, the lack of growth in zones about the various disks indicates the relative effectiveness of the antibiotic. (05 Mar 2000) |
| DNAse i sensitivity | <molecular biology> The likelihood that a particular DNA segment will be attacked by the endonuclease enzyme DNase I, which breaks down DNA into smaller fragments by cleaving its phosphodiester bonds. DNA segments which contain active genes that are regularly transcribed are more prone to being cut apart by DNase I than inactivated genes, because the inactivated genes are generally within condensed regions of the chromosome, while the active genes are in more open configurations for easy access for transcription.

| idiosyncratic sensitivity | A type I allergic reaction (atopic). (05 Mar 2000) |
