| spleen endonuclease | micrococcal endonuclease |
| spleen focus-forming viruses | Murine leukaemia viruses that are replication-defective and rapidly transforming. The envelope gene plays an essential role in initiating erythroleukaemia, manifested by splenic foci, splenomegaly, and polycythemia. Spleen focus-forming viruses are generated by recombination with other viral types including friend p (polycythemia), friend a (anaemia), rauscher, and cas (from wild mice at lake casita, california). (12 Dec 1998) |
| spleen metastases | <radiology> Ovarian (most common), melanoma, pancreatic (12 Dec 1998) |
| spleen phosphodiesterases | micrococcal endonuclease |
| spleen, ruptured | Rupture of the capsule of the spleen, an organ in the upper left part of the abdomen, is a potential catastrophe that requires immediate medical and surgical attention. Splenic rupture permits large amounts of blood to leak into the abdominal cavity which is severely painful.and life-threatening. Shock and, ultimately, death can result. Patients typically require an urgent operation. Rupture of a normal spleen can be caused by trauma, for example, in an accident. If an individual's spleen is enlarged, as is frequent in mononucleosis, most physicians will not allow activities (such as major contact sports) where injury to the abdomen could be catastrophic.

| diffuse waxy spleen | A condition of amyloid degeneration of the spleen, affecting chiefly the extrasinusoidal tissue spaces of the pulp. Synonym: lardaceous spleen (05 Mar 2000) |
