| syndrome, irritable bowel | A common gastrointestinal disorder (also called spastic colitis, mucus colitis or nervous colon syndrome), ibs is an abnormal condition of gut contractions (motility) characterised by abdominal pain, bloating, mucous in stools, and irregular bowel habits with more than alternating diarrhoea and constipation, symtoms that tend to be chronic and wax and wane over the years. Although ibs can cause chronic recurrent discomfort, it does not lead to any serious organ problems. Diagnosis usually involves more than excluding other illnesses. Treatment is directed toward relief of symptoms and includes high fibre diet, exercise, relaxation techniques, avoidance of caffeine, milk products and sweeteners, and medications. (12 Dec 1998) |

| inflammatory bowel disease | <disease> A general term that encompasses several disease processes, most commonly, ulcerative colitis and Crohn's disease. (27 Sep 1997) |
| inflammatory bowel diseases | Chronic, non-specific disorders of unknown aetiology. Includes crohn disease and ulcerative colitis. Extracolonic manifestations are often associated with inflammatory bowel disease (ibd) and involve the liver, joints and skin. (12 Dec 1998) |
| intramural bowel gas | <radiology> Pneumatosis cystoides intestinalis, necrotizing enterocolitis (NEC) - infants, mesenteric vascular thrombosis, necrosis due to strangulated obstruction, toxic ulcerative colitis, ulceration proximal to obstructing carcinoma, post-surgical changes (12 Dec 1998) |
| irritable bowel disease | <disease> A functional bowel disorder characterised by recurrent crampy abdominal pain and diarrhoea. Invasive gastrointestinal diagnostics are often unrevealing. (27 Sep 1997) |
| irritable bowel syndrome | <syndrome> A functional bowel disorder characterised by recurrent crampy abdominal pain and diarrhoea. Invasive gastrointestinal diagnostics are often unrevealing. (27 Sep 1997) |
| ischaemic bowel disease | <surgery> A disorder which results from the inadequate flow of oxygenated blood to the intestines. Symptoms include crampy abdominal pain after eating. More common in those with a history of atherosclerosis and-or diabetes. (15 Oct 1997) |
| bilaterally small, smooth kidneys | <radiology> Generalised atherosclerosis, nephrosclerosis - benign and malignant, atheroembolic renal disease, chronic glomerulonephritis, papillary necrosis, hereditary diseases, hereditary chronic nephritis (Alport's syndrome), medullary cystic disease, amyloidosis (late), arterial hypotension Cf: other urographic patterns (12 Dec 1998) |
| carcinoma, non-small-cell lung | A heterogeneous aggregate of at least three distinct histological types of lung cancer, including squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. They are dealt with collectively because of the shared properties of poor response to conventional chemotherapy and the potential for cure with surgical resection in a fraction of patients. (12 Dec 1998) |
| carcinoma, small cell | An anaplastic, highly malignant, and usually bronchogenic carcinoma composed of small ovoid cells with scanty neoplasm. It is characterised by a dominant, deeply basophilic nucleus, and absent or indistinct nucleoli. There are admixtures of small cell lung carcinoma with other types of lung cancer. Small cell carcinomas are distinguished by their distinctive biological features, response to chemotherapy and radiotherapy, and by their nearly universal tendency to develop overt or subclinical metastases, which frequently eliminates surgery in most patients. (12 Dec 1998) |
| mesenteric portion of small intestine | The freely movable portion of the small intestine supplied with a mesentery, comprising the jejunum and ileum. Synonym: mesenteric portion of small intestine. (05 Mar 2000) |
| ribonucleoproteins, small nuclear | Highly conserved nuclear RNA-protein complexes that function in RNA processing in the nucleus, including pre-mRNA splicing and pre-mRNA 3'-end processing in the nucleoplasm. The u3 snrnp is localised in the nucleolus, where it aligns into base pairs with the 28s rrna precursor in a still unidentified region and functions in pre-rrna processing. The u7 snrnp aligns into base pairs with a conserved sequence in the 3'-end of histone pre-mRNA and is an essential cofactor for the cleavage that creates the mature nonadenylated 3'-end. (12 Dec 1998) |
| ribonucleoproteins, small, u1 | A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the u1 snrnp along with other small ribonucleoproteins (u2, u4-u6, and u5) assemble into spliceosomes that remove introns from pre-mRNA by splicing. The u1 snrnp base pairs with conserved sequence motifs at the 5'-splice site and recognises both the 5'- and 3'-splice sites and may have a fundamental role in aligning the two sites for the splicing reaction. (12 Dec 1998) |
| ribonucleoproteins, small, u2 | A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the u2 snrnp along with other small ribonucleoproteins (u1, u4-u6, and u5) assemble into spliceosomes that remove introns from pre-mRNA by splicing. The u2 snrnp base pairs with conserved sequence motifs at the branch point, which associates with a heat- and rnaase-sensitive factor in an early step of splicing. (12 Dec 1998) |
| ribonucleoproteins, small, u4-u6 | A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the u4-u6 snrnp along with the u5 snrnp preassemble into a single 25s particle that binds to the u1 and u2 snrnps and the substrate to form mature spliceosomes. There is also evidence for the existence of individual u4 or u6 snrnps in addition to their organization as a u4-u6 snrnp. (12 Dec 1998) |
