|---|---|
| intracutaneous reaction | Intradermal reaction, a reaction following the injection of antigen into the skin of a sensitive subject, such as in the case of the tuberculin test. (05 Mar 2000) |
| iodate reaction of epinephrine | A reaction dependent upon the oxidation of epinephrine by iodine liberated from iodate, which is decomposed by the hormone; a faint pink colour results. (05 Mar 2000) |
| iodine reaction of epinephrine | A reaction resulting from the oxidation of the hormone, a faint pink colour appearing upon the addition of iodine. (05 Mar 2000) |
| irreversible reaction | A reaction or response by the tissues to a pathogenic agent characterised by a permanent pathologic change. (05 Mar 2000) |
| oxidase reaction | The formation of indol blue when a blood smear containing myeloid leukocytes is treated with a mixture of alpha-naphthol and p-dimethylaniline sulfate; the myeloid leukocytes contain an oxidase that catalyses this reaction, the lymphoid leukocytes do not, in bacteriology, a reaction that depends on the presence of certain oxidases in some bacteria that catalyze the transport of electrons between electron donors in the bacteria and an oxidation reduction dye, such as tetramethyl-p-phenylenediamine; the dye is reduced to a blue or black colour. (05 Mar 2000) |
| oxidation-reduction reaction | <chemistry> Any reaction in which electrons are removed from one molecule or atom and given to another molecule or atom. (09 Oct 1997) |
| thermonuclear reaction | <radiobiology> See thermonuclear fusion, above. (09 Oct 1997) |
| thermoprecipitin reaction | The throwing down of a precipitate on the application of heat, as in the case of proteinaceous urine. (05 Mar 2000) |
| early 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) |
| echo reaction | A disorder of speech where there is an involuntary repetition several times of the same word. (27 Sep 1997) |
| Ehrlich reaction | The reaction of the indole derivatives with aromatic aldehydes; e.g., tryptophan and p-dimethylaminobenzaldehyde in H2SO4 give a red-violet colour useful in assaying proteins for tryptophan content. Synonym: Ehrlich reaction. (05 Mar 2000) |
| Ehrlich's benzaldehyde reaction | A test for urobilinogen in the urine, by dissolving 2 g of dimethyl-p-aminobenzaldehyde in 100 ml of 5% hydrochloric acid and adding this reagent to urine; a red colour in the cold indicates the presence of an excessive amount of urobilinogen. (05 Mar 2000) |
| Ehrlich's 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) |
| transfusion reaction | A reaction to a blood transfusion secondary to some incompatibility in type, RH factor or other surface antigens. May be manifest by haemolytic anaemia, heart failure, and-or renal failure. Symptoms include facial flushing, angioedema, headache, wheezing, anaphylaxis, shock, fever, chills and breathing difficulty. (27 Sep 1997) |
