| natural products | Naturally occurring compounds that are end products of secondary metabolism; often, they are unique compounds for particular organisms or classes of organisms. (05 Mar 2000) |
|---|---|
| dairy products | Raw and processed or manufactured milk and milk-derived products. These are usually from cows (bovine) but are also from goats, sheep, reindeer, and water buffalo. (12 Dec 1998) |
| orphan products | Drugs, biologicals, and medical devices (including diagnostic in vitro tests) that may be useful in common or rare diseases but which are not considered commercially viable. Synonym: orphan drugs. (05 Mar 2000) |
| fibrin degradation products | <haematology, investigation> A test that measures fibrin degradation products which result from the dissolution of a blood clot. Normal value is less than 10 mcg/ml (micrograms per millilitre). They may be increased in conditions such as burns, placental abruption, heart disease, DIC, after massive blood transfusion, hypoxia, intrauterine foetal death, portacaval shunt, leukaemia, transfusion reaction, transplant rejection, sepsis, renal failure and preeclampsia. Acronym: FDP (23 Sep 2002) |
| fibrin fibrinogen degradation products | <chemical> Soluble protein fragments formed by the proteolytic action of plasmin on fibrin or fibrinogen. Fdp and their complexes profoundly impair the haemostatic process and are a major cause of haemorrhage in intravascular coagulation and fibrinolysis. Pharmacological action: antithrombins. (12 Dec 1998) |
| fish products | Food products manufactured from fish (e.g., fish flour, fish meal). (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) |
