| COLD | Chronic Obstructive Lung Disease |
| COWS | Cold Opposite, Warm Same |
| hysterectomy, complete | Complete surgical removal of the uterus and cervix. Also called a total hysterectomy. (12 Dec 1998) |
|---|---|
| denture, complete | A denture replacing all natural teeth and associated structures in both the maxilla and mandible. (12 Dec 1998) |
| denture, complete, immediate | A complete denture constructed for replacement of natural teeth immediately after their removal. It does not fit the mouth perfectly and is intended only for functional and cosmetic purposes during the healing process after total extraction. It is to be replaced by the fitted permanent denture. (12 Dec 1998) |
| denture, complete, lower | A complete denture replacing all the natural mandibular teeth and associated structures. It is completely supported by the oral tissue and underlying mandibular bone. (12 Dec 1998) |
| denture, complete, upper | A complete denture replacing all the natural maxillary teeth and associated maxillary structures. It is completely supported by the oral tissue and underlying maxillary bone. (12 Dec 1998) |
| Freund's complete adjuvant | Water-in-oil emulsion of antigen, to which killed mycobacteria or tuberculosis bacteria are added. (05 Mar 2000) |
| paroxysmal cold haemoglobinuria | <haematology> A rare blood disorder caused by antibodies which destroy red blood cells upon exposure to the cold. The antibodies are formed against a specific blood group and are triggered by the cold. The cause is unknown but the disease has been associated with syphilis and some viral infections. Serum haemoglobin and urine haemoglobin are increased during the attacks. The disease is chronic and treatment is difficult. Some cases resolve spontaneously without treatment. Origin: Gr. Ouron = urine (27 Sep 1997) |
| rose cold | Allergic rhinitis occurring in the spring and early summer. (05 Mar 2000) |
| warm-cold haemolysin | Haemolysin which combines with red blood cells at temperatures below 20캜 and are eluted at warmer temperatures, e.g., 30 to 37캜. See: Donath-Landsteiner cold autoantibody, haemagglutinating cold autoantibody. (05 Mar 2000) |
| cold | <virology> A slang term that describes a viral upper respiratory infection which results from inflammation of the mucous membranes of the nasal cavity. (27 Sep 1997) |
| cold abscess | An abscess without heat or other usual signs of inflammation. Synonym: tuberculous abscess. (05 Mar 2000) |
| cold agglutination | The agglutination of red blood cells by their own serum (see autoagglutination), or by any other serum when the blood is cooled below body temperature, but most pronounced below 25캜; the phenomenon results from cold agglutinins; may be seen occasionally in the blood of apparently normal persons or as a pathologic finding in patients with primary atypical pneumonia, infectious mononucleosis, and other viral diseases, certain protozoan infections, or lymphoproliferative neoplasms. See: autoagglutination. (05 Mar 2000) |
| cold agglutination test | <investigation> A test for blood antibodies which are present in certain peculiar types of pneumonia (atypical pneumonia, Mycoplasma) (27 Sep 1997) |
| cold agglutinin | An antibody which reacts more efficiently at temperatures below 37캜. (05 Mar 2000) |
| cold agglutinins | <haematology> Antibodies that agglutinate particles with greater activity below 32쵣. They are IgM antibodies specifically reactive with blood groups I and i in humans and agglutinate red blood cells on cooling, causing Raynaud's phenomenon in vivo. (18 Nov 1997) |
