| sprains and strains | A collective term for muscle and ligament injuries without dislocation or fracture. A sprain is a joint injury in which some of the fibres of a supporting ligament are ruptured but the continuity of the ligament remains intact. A strain is an overstretching or overexertion of some part of the musculature. (12 Dec 1998) |

| animals, inbred strains | Animals produced by the mating of littermates or siblings over multiple generations. The resultant strain of animals is virtually identical genotypically. Highly inbred animal lines allow the study of certain traits in a relatively pure form. (12 Dec 1998) |
| auxotrophic strains | Strain's which are derived from the prototrophic strain but which require extra growth factors. (05 Mar 2000) |
| rats, inbred strains | Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations or by parent x offspring matings carried out with certain restrictions. This also includes animals with a long history of closed colony breeding. (12 Dec 1998) |
| rats, mutant strains | Rats bearing mutant genes which are phenotypically expressed in the animals. (12 Dec 1998) |
| mice, inbred strains | Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation. (12 Dec 1998) |
| mice, mutant strains | Mice bearing mutant genes which are phenotypically expressed in the animals. (12 Dec 1998) |
| prototrophic strains | Strain's that have the same nutritional requirements as the wild-type strain. (05 Mar 2000) |
| abortion, multiple | Couples who have had 2 or more miscarriages (spontaneous abortions) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| amyloidosis of multiple myeloma | Foci of amyloidosis in mesenchymal tissues of some persons with multiple myeloma; no direct relation between amyloid and Bence Jones protein is conclusively known. (05 Mar 2000) |
| cancer, multiple myeloma | A bone marrow cancer involving a type of white blood cell called a plasma (or myeloma) cell. The tumour cells can form a single collection (a plasmacytoma) or many tumours (multiple myeloma). Plasma cells are part of the immune system and make antibodies. Because patients have an excess of identical plasma cells, they have too much of one type of antibody. As myeloma cells increase in number, they damage and weaken the bones, causing pain and often fractures. When bones are damaged, calcium is released into the blood leading to hypercalcaemia (excess calcium in the blood) and that causes loss of appetite, nausea, thirst, fatigue, muscle weakness, restlessness, and confusion. Myeloma cells prevent the bone marrow from forming normal plasma cells and other white blood cells important to the immune system so patients may not be able to fight infections. The cancer cells can also prevent the growth of new red blood cells, causing anaemia. Excess antibody proteins and calcium may prevent the kidneys from filtering and cleaning the blood properly Cancer, non-Hodgkin's lymphoma: A lymphoma is a cancer that develops in the lymphatic system. The most common symptom of non-Hodgkin's lymphomas is a painless swelling in the lymph nodes in the neck, underarm, or groin. Non-Hodgkin's lymphomas are diagnosed with a biopsy of an enlarged lymph node. Follow-up examinations are important after lymphoma treatment. Most relapses occur in the first 2 years after therapy.

| chromosomes in multiple miscarriages | Couples who have had more than one miscarriage (spontaneous abortion) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| miscarriages, multiple, chromosomes in | Couples who have had more than one miscarriage have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| multiple | Manifold, occurring in or affecting various parts of the body at once. Origin: L. Multiplex (18 Nov 1997) |
