| AMLR | autologous mixed lymphocyte reaction |
| ANAP | agglutination negative, absorption positive [reaction] |
| detoxification reaction | Reactions taking place generally in the liver or kidney in order to inactivate toxins, either by degradation or else by conjugation of residues to a hydrophilic moiety to promote excretion. (18 Nov 1997) |
|---|---|
| diazo reaction | The reaction of diazotised sulfanilic acid with bilirubin to form azobilirubin, which forms the basis of quantitating the amount of bilirubin in biological fluids. See: van den Bergh's test. Synonym: Ehrlich's diazo reaction. (05 Mar 2000) |
| digitonin reaction | The reaction of naturally occurring steroids with 3b-hydroxyl groups with digitonin, a steroid glycoside, resulting in the formation of an insoluble precipitate; useful in determining the presence of cholesterol and ergosterol. (05 Mar 2000) |
| Dische reaction | The assay of DNA by means of the blue colour formed with diphenylamine in acid (Dische reagent). (05 Mar 2000) |
| dissociative reaction | Reaction characterised by such dissociative behaviour as amnesia, fugues, sleepwalking, and dream states. (05 Mar 2000) |
| DNA-driven reaction | <molecular biology> A lab technique to mark highly-repeated DNA sequences with a radioactive RNA tracer, by having a much larger amount of complementary DNA molecules than radioactive RNA tracer molecules. (09 Oct 1997) |
| dopa reaction | A dark staining observed in fresh tissue sections to which a solution of dopa has been applied, presumably due to the presence of dopa oxidase in the protoplasm of certain cells. Synonym: Bloch's reaction. (05 Mar 2000) |
| id reaction | An allergic manifestation of candidiasis, the dermatophytoses, and other mycoses characterised by itching, vesicular lesions that appear in response to circulating antigens at sites that are often far distant from the primary fungal lesion itself. See: dermatophytid, -id. (05 Mar 2000) |
| dystonic reaction | <pharmacology> Prolonged muscle contractions that may cause twisting and repetitive movements or abnormal posture. May occur in the form of rhythmic jerks. Can be seen as a side effect from antipsychotic medications and drugs used in the treatment of Parkinson's disease. (27 Sep 1997) |
| immediate hypersensitivity reaction | An immune response mediated by antibody, usually IgE, which occurs within minutes after a second encounter with an antigen, resulting in the release of histamine and subsequent swelling and vasodilation. (05 Mar 2000) |
| immediate reaction | Local or generalised response that begins within a few minutes to about an hour after exposure to an antigen to which the individual has been sensitised. See: skin test, wheal-and-erythema reaction. Synonym: early reaction. (05 Mar 2000) |
| incompatible blood transfusion reaction | A syndrome due to intravascular haemolysis of transfused blood by serum antibodies of the recipient, which react with an antigen of the donor red cells; characterised by chills, fever (often with urticaria), backache or muscle cramps, haemoglobinaemia, haemoglobinuria, and oliguria, which may result in acute renal failure, DIC, and death. (05 Mar 2000) |
| Quellung reaction | Swelling of the capsule surrounding a bacterium as a result of interaction with anticapsular antibody, consequently the capsule becomes more refractile and conspicuous. (18 Nov 1997) |
| indirect pupillary reaction | Contraction of the pupil of the fellow eye in consensus with the pupil of the illuminated eye. Synonym: consensual light reflex, indirect pupillary reaction. (05 Mar 2000) |
| insulin reaction | A sudden uncontrolled decline in the blood sugar due to effects of insulin. (27 Sep 1997) |
