| serum hepatitis | <virology> A form of viral hepatitis, known as serum hepatitis, because it is commonly spread through contact with infected blood products (transfusion). May also be spread sexually or from mother to infant. Hepatitis B can cause a much more severe infection than hepatitis A and can occur as an asymptomatic carrier state, a chronic infection or as cirrhosis of the liver. Those at risk (IV drug abusers, health care workers, dialysis patients, transfusion recipients, homosexuals) should be immunised with hepatitis B vaccine. The virus is 42nm diameter, with an outer sheath enclosing inner 27nm core particle containing the circular viral DNA. Aggregates of the envelope proteins are found in plasma and are referred to as hepatitis B surface antigen (HBsAg, previously called Australia antigen). The virus can persist for long periods (and in asymptomatic carriers), association of integrated virus with hepatocellular carcinoma is now well established. (27 Sep 1997) |

| serum hepatitis virus | The type species of the genus orthohepadnavirus which causes human hepatitis b and is also apparently a causal agent in human hepatocellular carcinoma. The dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum. (12 Dec 1998) |
| serum immunofixation | A special laboratory technique that is used to identify specific proteins in the blood or urine. It has greatest application in the identification (and monitoring) of monoclonal proteins that are produced in conditions like Waldenstom's macroglobulinaemia and multiple myeloma. (27 Sep 1997) |
| serum immunoglobulin electrophoresis | A test that detects and measures the various immunoglobulins in the blood. In the normal assay no monoclonal antibodies are detected. In multiple myeloma and chronic lymphocytic leukaemia a single clone of lymphocytes can produce one type of immunoglobulin that is detected in the electrophoresis as monoclonal (made by one cell clone). (27 Sep 1997) |
| serum iron level | A test that measures the amount of iron (Fe ++) in the blood. The test is performed when iron deficiency is suspected. Normal serum iron is 60 to 170 mcg/dl. Increased levels may be seen in the following: haemochromatosis, haemolysis, haemolytic anaemia, hepatitis, liver necrosis, haemosiderosis, iron poisoning and lead toxicity. Lower than normal levels are seen in chronic GI blood loss, iron deficiency anaemia, insufficient dietary iron, malabsorption, chronic heavy menstrual bleeding, nephrosis and late pregnancy.

| serum lactis | <biology> The fluid protion of milk that separates from curd. (09 Oct 1997) |
| serum nephritis | Glomerulonephritis occurring in serum sickness or in animals injected with foreign serum protein. (05 Mar 2000) |
| serum proteins | Dissolved protein's (more than 100) of blood plasma, mainly albumins and globulins (normally 6 to 8 g/100 ml); they hold fluid in blood vessels by osmosis and include antibodies and blood-clotting protein's. Synonym: serum proteins. (05 Mar 2000) |
| serum prothrombin conversion accelerator | <chemical> Heat- and storage-stable plasma protein that is activated by tissue thromboplastin to form factor viia in the extrinsic pathway of blood coagulation. The activated form then catalyses the activation of factor x to factor xa. Chemical name: Blood-coagulation factor VII (12 Dec 1998) |
| serum reaction | A hypersensitivity response (type III) to the injection of large amounts of antigen, as might happen when large amounts of antiserum are given in a passive immunisation. The effects are caused by the presence of soluble immune complexes in the tissues. (18 Nov 1997) |
| serum requirement | The amount of serum that must be added to culture medium to permit growth of an animal cell in culture. Transformed cells frequently have less stringent serum requirements than their normal counterparts. (18 Nov 1997) |
| serum response element | Dyad symmetry element bound by serum response factor to control the expression of c fos. (18 Nov 1997) |
| serum response factor | Transcription factor that binds to the serum response element upstream of the site of transcription initiation of genes such as c fos. (18 Nov 1997) |
| serum shock | Anaphylactic or anaphylactoid shock caused by the injection of antitoxic or other foreign serum. (05 Mar 2000) |
| serum sickness | A hypersensitivity response (type III) to the injection of large amounts of antigen, as might happen when large amounts of antiserum are given in a passive immunisation. The effects are caused by the presence of soluble immune complexes in the tissues. (18 Nov 1997) |
