| evoked response audiometry | A type of electrophysiologic audiometry in which electrical potentials of neural impulses from the cochlear nerve and various levels in the brain in response to acoustic stimulation are used to localise the site of a lesion causing a hearing loss. (05 Mar 2000) |
|---|---|
| unconditioned response | A response, such as salivation, which is a part of the animal or human repertoire. Compare: conditioned response. (05 Mar 2000) |
| flight or fight response | See: emergency theory. (05 Mar 2000) |
| late-phase response | Recurrence of symptoms after an appreciable interval following challenge with an antigen; preceded by an initial early-phase response. (05 Mar 2000) |
| lh response to gnrh | This test measures the level of luteinising hormone in the blood after an injection of gonadotrophin releasing hormone (GNRH), normally produced in the hypothalamus. This will test the ability of the pituitary gland to respond by measuring one of the pituitary glands byproducts, luteinising hormone. This test is used to differentiate hypogonadism (ovary or testes) into primary hypogonadism (problem is with the ovary or testes) or secondary hypogonadism (problem is with the pituitary gland or the hypothalamus). (27 Sep 1997) |
| lymphoproliferative response | <haematology, immunology> A specific immune response that entails rapid T-cell replication. Standard antigens, such as tetanus toxoid, that elicit this response are used in lab tests of immune competence. (13 Nov 1997) |
| accelerator factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| acetate replacement factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| adrenal weight factor | A postulated substance of adenohypophysial origin responsible for maintenance of the weight of the adrenal cortex. (05 Mar 2000) |
| adrenocorticotropic releasing factor | Hormone produced by hypothalamus that causes pituitary to secrete adrenocorticotropic hormone. (05 Mar 2000) |
| a-factor | <molecular biology> A protein which is found in the bacterial genus Streptomyces that helps start the production of streptomycin and the process of morphological differentiation. It is used in biotechnology to induce these functions in mutant strains of Streptomyces that cannot produce it themselves. (09 Feb 1998) |
| angiogenesis factor | Substance causing proliferation of new blood vessels. It is found in tissues with high metabolic requirements, such as the retina, and in certain cancers. The factor is also released by hypoxic macrophages at the edges or outer surfaces of wounds and initiates revascularization in wound healing. (12 Dec 1998) |
| animal protein factor | <biochemistry> Member of the water soluble B vitamin group, important in the proper function of the nervous system and important in proper carbohydrate, protein and fat metabolism. (27 Sep 1997) |
| antialopecia factor | A member of the vitamin B complex necessary for growth of yeast and of mice, absence from the diet causes hair loss and dermatitis in mice. (27 Sep 1997) |
| antianaemic factor | <biochemistry> Member of the water soluble B vitamin group, important in the proper function of the nervous system and important in proper carbohydrate, protein and fat metabolism. (27 Sep 1997) |
