| tuberculin-type hypersensitivity | A local or generalised response that begins 24 to 48 hours after exposure to an antigen. See: cell-mediated reaction. Synonym: contact hypersensitivity, delayed hypersensitivity, late reaction, tuberculin-type hypersensitivity. (05 Mar 2000) |

| type III hypersensitivity reaction | An immunologic category of diseases evoked by the deposition of antigen-antibody or antigen-antibody-complement complexes on cell surfaces, with subsequent involvement of breakdown products of complement, platelets, and polymorphonuclear leukocytes, and development of vasculitis; nephritis is common. Arthus phenomenon and serum sickness are classic examples, but many other disorders, including most of the connective tissue disease's, may belong in this immunologic category; immune complex disease's can also occur during a variety of disease's of known aetiology, such as subacute bacterial endocarditis. See: autoimmune disease. Synonym: immune complex disorder, type III hypersensitivity reaction. (05 Mar 2000) |
| food hypersensitivity | Gastrointestinal disturbances, skin eruptions, or shock due to allergic reactions to allergens ingested in food. (12 Dec 1998) |
| prenatal exposure delayed effects | Delayed effects on offspring of maternal or foetal prenatal exposure to drugs, radiation and other physical agents, manipulation, nutrition, stress, etc. (12 Dec 1998) |
| puberty, delayed | Unusually late sexual maturity. (12 Dec 1998) |
| delayed-action preparations | Dosage forms of a drug that act over a period of time. (12 Dec 1998) |
| delayed allergy | A type IV allergic reaction; so called because in a sensitised subject the reaction becomes evident hours after contact with the allergen (antigen), reaches its peak after 36 to 48 hours, then recedes slowly. Associated with cell-mediated responses. See: delayed reaction. Compare: immediate allergy. (05 Mar 2000) |
| delayed coma after hypoxia | Coma that develops a few days to 3 weeks after an acute hypoxic insult; the latter was usually severe enough to cause an initial bout of coma, which cleared, and was followed by a transient interval of apparent normality. Synonym: severe postanoxic encephalopathy. (05 Mar 2000) |
| delayed conduction | First-degree A-V block. See: atrioventricular block, intraventricular block, bundle-branch block. (05 Mar 2000) |
| delayed dentition | Delayed eruption of the teeth. (05 Mar 2000) |
| delayed eruption | A dental eruption pattern which is chronologically late in comparison with the average pattern of dental eruption; eruption of the first tooth occurs at a later age than the average, and the intervals of time between subsequent dental eruption's are longer than the average. Drug eruption, any eruption caused by the ingestion, injection, or inhalation of a drug, most often the result of allergic sensitization; reactions to drugs applied to the cutaneous surface are not generally designated as drug eruption, but as contact-type dermatitis. Synonym: dermatitis medicamentosa, dermatosis medicamentosa, drug rash, medicinal eruption. (05 Mar 2000) |
| delayed flap | A flap raised in its donor area in two or more stages to increase its chances of survival after transfer. (05 Mar 2000) |
| delayed gastric emptying | <gastroenterology> A condition where there is delayed stomach emptying (due abnormal gastric motility), often see as a complication of diabetes mellitus. Risk factors include diabetes, systemic sclerosis, previous vagotomy, previous gastrectomy, viceral neuropathy and the use of anticholinergic medications. Symptoms include bloating, nausea, vomiting and constipation. Treatment include dietary modification and the use of cholinergic medications and metachlopromide. (27 Sep 1997) |
| delayed graft | Application of a skin graft after waiting several days for healthy granulations to form. (05 Mar 2000) |
| delayed implantation | A phenomenon characterised by an interval ranging from a few weeks to approximately 6 months between the time an ovum is fertilised and subsequent implantation of the zygote, as in the marten and the armadillo. (05 Mar 2000) |
