| neuritis, experimental allergic | An autoimmune demyelinating disorder of peripheral nerves produced by injection of peripheral nerve tissue protein. (12 Dec 1998) |
|---|---|
| dermatitis, allergic contact | A contact dermatitis due to allergic sensitization to various substances. These substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure. (12 Dec 1998) |
| encephalomyelitis, allergic | An experimental demyelinating disease produced in animals by injections of myelin fractions in order to study the relationship between hypersensitivity and the demyelinating diseases. (12 Dec 1998) |
| experimental allergic encephalitis | <pathology> An autoimmune disease that can be induced in various experimental animals by the injection of homogenised brain or spinal cord in Freund's adjuvant. The antigen appears to be a basic protein present in myelin and the response is characterised by focal areas of lymphocyte and macrophage infiltration into the brain, associated with demyelination and destruction of the blood-brain barrier. Sometimes used as a model for demyelinating diseases, although whether this is entirely justifiable is not clear. (18 Nov 1997) |

| extrinsic allergic alveolitis | <radiology> Exposure to organic dust less than 5u in size, recurrent episodes of fever, chills, dry cough, dyspnea following exposure after 6 hr interval (10-40% assymptomatic), spontaneous resolution in 1-2 days, farmer's lung, Pandora's pneumonitis, bird-fancier's lung, mushroom worker's lung, bagassosis, malt worker's lung, maple bark disease, suberosis, sequoiosis see: acute extrinsic allergic alveolitis, hypersensitivity pneumonitis (12 Dec 1998) |
| anamnestic response | <immunology> Archaic term now replaced by such terms as secondary immune response, immune memory. (18 Nov 1997) |
| audiometry, evoked response | A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry. (12 Dec 1998) |
| auditory brainstem response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| biological response modifier | <pharmacology, oncology> A substance used in adjuvant therapy that takes advantage of the bodys own natural defense mechanisms to inhibit the growth of a tumour. (16 Dec 1997) |
| biological response modifiers | Substances that stimulate the body's response to infection and disease. The body naturally produces small amounts of these substances. Scientists can produce some of them in the laboratory in large amounts and use them in cancer treatment. Also called BRMs. (12 Dec 1998) |
| biphasic response | Two separate and distinct responses that are separated in time, immediate reaction to an antigenic challenge followed by a recurrence of symptoms after an interval of quiescence. (05 Mar 2000) |
| booster response | The response of the immune system to the second or subsequent occasion on which it encounters a specific antigen. (18 Nov 1997) |
| brainstem evoked response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| galvanic skin response | A change in electrical resistance of the skin, occurring in emotion and in certain other conditions. (12 Dec 1998) |
