| 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 hypersensitivity | <immunology> Hypersensitivity (increased reaction by the body to a foreign substance such as an antigen or allergen) that does not appear until 24 to 48 hours after the body is exposed to the foreign substance. (09 Oct 1997) |
| 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) |
| delayed reaction | 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) |
| delayed reaction experiment | A method of measuring memory: a stimulus is presented and removed before the organism is permitted to respond to it; the interval during which the stimulus is absent, providing the organism responds correctly, is an indication of the length of memory. (05 Mar 2000) |
| delayed rectifier channel | <physiology> The potassium selective ion channels of axons, so called because they change the potassium conductance with a delay after a voltage step. The name is used to denote any axon like K channel. Various roles for example regulation of pacemaker potentials, generation of bursts of action potentials or generation of long plateaus on action potentials. (18 Nov 1997) |
| delayed reflex | A reflex in which a little time elapses between stimulus and response. See: trace conditioned reflex. (05 Mar 2000) |
| delayed sensation | A sensation that is not perceived until the lapse of an appreciable interval following the application of the stimulus. General sensation, a sensation referred to the body as a whole rather than to any particular part. (05 Mar 2000) |
| delayed suture | A suturing of a wound after an interval of days. (05 Mar 2000) |
| delayed type hypersensitivity | <immunology> Hypersensitivity (increased reaction by the body to a foreign substance such as an antigen or allergen) that does not appear until 24 to 48 hours after the body is exposed to the foreign substance. (09 Oct 1997) |
| ovum implantation, delayed | Delay of embryonal development whereby the blastocyst remains in the uterine cavity for a variable period of time before attaching to the endometrium and continuing its development. (12 Dec 1998) |
| arterial transfusion | Direct transfusion from an artery of the donor into an artery of the receptor. (05 Mar 2000) |
| blood component transfusion | The transfer of blood components such as erythrocytes, leukocytes, platelets, and plasma from a donor to a recipient or back to the donor. This process differs from the procedures undertaken in plasmapheresis and types of cytapheresis (plateletpheresis and leukapheresis) where, following the removal of plasma or the specific cell components, the remainder is transfused back to the donor.
