| 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) |
| immune adherence reaction | A method for the detection of very small quantities of antibody in which the antigen-antibody-complement complex adheres to indicator cells, usually primate erythrocytes or nonprimate blood platelets. The reaction is dependent on the number of bound c3 molecules on the c3b receptor sites of the indicator cell. (12 Dec 1998) |
| immune reaction | Antigen-antibody reaction indicating a certain degree of resistance, usually in reference to the 36-to 48-hour reaction in vaccination against smallpox; because the degree of resistance indicated by the reaction is not true immunity and may disappear relatively rapidly there is a tendency to refer to the immune reaction as an allergic 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) |
| 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) |
