|---|---|
| normal hearing | The ability to perceive sound normally. Synonym: normal hearing. Origin: G. Akousis, hearing (05 Mar 2000) |
| normal horse serum | The sterile and filtered serum of a healthy, unvaccinated horse. (05 Mar 2000) |
| normal occlusion | That arrangement of teeth and their supporting structure which is usually found in health and which approaches an ideal or standard arrangement. Synonym: normal bite. Synonym: neutral occlusion. (05 Mar 2000) |
| normal opsonin | That normally present in the blood, i.e., without stimulation by a known, specific antigen such as certain complement components; it is relatively thermolabile and reacts with various organisms. Synonym: common opsonin, thermolabile opsonin. Specific opsonin, antibodies formed in response to stimulation by a specific antigen, either as a result of an attack of a disease, or injections with a suitably prepared suspension of the specific microorganism. Synonym: immune opsonin, thermostable opsonin. (05 Mar 2000) |
| normal pressure hydrocephalus | <neurology> A brain disorder caused by blockage of the flow of cerebrospinal fluid (CSF), with enlargement of the ventricles of the brain (keep the pressure normal) and compression of brain tissue. Brain atrophy is the result. In this condition the CSF is produced normally but not reabsorbed. Symptom onset is gradual. A key feature is dementia. Treatment is surgical (VP shunt). (13 Nov 1997) |
| normal range | Normal results can fall outside the normal range. By convention, the normal range is set to cover ninety-five percent (95%) of values from a normal population. Five percent (5%) of normal results therefore fall outside the normal range. (12 Dec 1998) |
| normal serum | A nonimmune serum, usually with reference to a serum obtained prior to immunization. (05 Mar 2000) |
| normal tartrate | Tartrate that contains no uncombined acid groups. (05 Mar 2000) |
| normal toxin | A toxin solution holding exactly 100 lethal doses in 1 ml. (05 Mar 2000) |
| normal values | A set of laboratory test value's used to characterise apparently healthy individuals; now replaced by reference value's. (05 Mar 2000) |
| anti-D immunoglobulin | rHo(D) immune globulin |
| rabies immunoglobulin | rabies immune globulin (human) |
| genes, immunoglobulin | Genes encoding the light and heavy chain segments of immunoglobulins. Light chain gene segments are symbolised l-v (variable), j (joining) and c (constant); ig heavy chain segments have, in addition, a diversity (d) gene. Each segment codes for certain amino acids, and each has a different nucleotide sequence; the genes are assembled by a remarkable shuffling of the segments during b lymphocyte maturation. (12 Dec 1998) |
| receptors, polymeric immunoglobulin | Specialised fc receptors (receptors, fc) for polymeric immunoglobulins, which mediate transcytosis of polymeric IgA and IgM into external secretions. They are found on the surfaces of epithelial cells and hepatocytes. After binding to IgA, the receptor-ligand complex undergoes endocytosis, transport by vesicle, and secretion into the lumen by exocytosis. Before release, the part of the receptor (secretory component) that is bound to IgA is proteolytically cleaved from its transmembrane tail. (12 Dec 1998) |
