| dark reaction | <biochemistry, plant biology> The reactions in photosynthesis that occur after NADPH and ATP production and that take place in the stroma of the chloroplast. By means of the reaction, carbon dioxide is incorporated into carbohydrate. (18 Nov 1997) |
| dark t2 lesion | <radiology> (short T2), acute haemorrhage (deoxyHb), haemosiderin, physiologic iron (basal ganglia, etc.), mucinous lesions (?) most abnormalities have long T1 and T2 (dark/bright). Compare: bright T1 lesion. (07 Mar 2000) |
| interstitial cell | 1. <plant biology> Cells lying between but distinct from other cells in a tissue, a good example being the interstitial cells in Hydra that serve as stem cells. 2. <pathology> Cells lying between the testis tubules of vertebrates and that are responsible for the secretion of testosterone. (18 Nov 1997) |
| interstitial cell-stimulating hormone | <protein> Synonym for luteinising hormone. (18 Nov 1997) |
| interstitial cell tumour of testis | <tumour> A small benign tumours of the testis that often produce testosterone, causing endocrine symptoms. Synonym: interstitial cell tumour of testis. (05 Mar 2000) |
| interstitial giant cell pneumonia | A rare complication of measles, with the postmortem finding of multinucleated giant cells lining alveoli. Synonym: Hecht's pneumonia, interstitial giant cell pneumonia. (05 Mar 2000) |
| interstitial plasma cell pneumonia | <chest medicine> A pneumonia caused by an infection with Pneumocystis carinii. Pneumocystis carinii grows rapidly in the lungs of patients with immunosuppression, particularly due to AIDS and is the leading AIDS-related cause of death. Pneumocystis carinii infection sometimes may occur elsewhere in the body (skin, eye, spleen, liver or heart). It is considered one of the diagnostic criteria for AIDS in an HIV positive individual. (10 Jan 1998) |
| acute interstitial nephritis | <nephrology> A relatively uncommon condition which is characterised by inflammation of the renal tubules, glomeruli and surrounding tissue. Interstitial nephritis is usually be temporary and often associated with the use of a particular medication. Chronic and progressive forms do exist. Drugs that have been associated with interstitial nephritis include penicillins, ampicillin, sulpha drugs, non-steroidal anti-inflammatory agents, furosemide and thiazide diuretics. May result in mild kidney dysfunction or acute renal failure. Treatment may be with corticosteroids. Incidence: 1 in 25,000. (29 Dec 1997) |
| acute interstitial pneumonia | A severe and usually fatal form of pneumonia occurring primarily in infants usually considered a form of hypersensitivity pneumonitis. (05 Mar 2000) |
| acute interstitial pneumonitis | Usually considered a form of hypersensitivity pneumonitis. (05 Mar 2000) |
| apical interstitial lung disease | <radiology> A radiological diagnosis where fibrosis is seen in the apices (upper sections) of the lungs. Likely causes include: cystic fibrosis, ankylosing spondylitis, sarcoidosis, silicosis, eosinophlic granuloma, TB and fungus, particularly aspergillus infection. (25 Jun 1999) |
| basilar interstitial lung disease | <radiology> B bronchiectasis, A asbestosis, D drugs / DIP, L lymphangitic metastasis / LAM, A aspiration, S sarcoidosis, S scleroderma (12 Dec 1998) |
| chronic interstitial hepatitis | An obsolete term for cirrhosis of the liver. (05 Mar 2000) |
| chronic interstitial hypertrophic neuropathy | dejerine-Sottas disease |
