| hot salt steriliser | A steriliser for endodontic equipment in which table salt is heated in a container at 218 to 246캜; the dry heat is transmitted to root canal instruments, absorbent points, or cotton pellets for their rapid (5 to 10 seconds) sterilization. (05 Mar 2000) |
| hot-short | <chemistry> More or less brittle when heated; as, hot-short iron. Source: Websters Dictionary (01 Mar 1998) |
| hot spleen | <radiology> Decreased liver uptake, liver disease (e.g., cirrhosis), shunting of portal venous blood, increased splenic uptake, haematopoietic disease, septicaemia, rheumatoid disorders, immunostimulation (tumour, Aldomet, IL-2) see: liver-spleen scan (12 Dec 1998) |
| hot spot | <molecular biology> A particular area of DNA which is especially prone to spontaneous mutations or recombinations. (09 Oct 1997) |
| hot thyroid nodule | <radiology> Almost always hyperfunctioning adenoma, vast majority benign, up to 50% are autonomous see also: thyroid carcinoma, cold thyroid nodule (12 Dec 1998) |
| 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) |
