| diffuse interstitial fibrosis | Progressive fibrous changes and scarring within the lung tissue, eventually interfering with normal gas exchange. (27 Sep 1997) |
|---|---|
| diffuse interstitial pulmonary fibrosis | This represents a group of pulmonary disorders (lower respiratory tract) that leads to a functional loss in the alveolar air sacs and a compromise in the diffusion of oxygen from air to blood. There is widespread inflammation and scar tissue (fibrosis) formation within the lung. The causes are varied and include: inorganic and organic dusts, gases, fumes, vapors, infections, radiation, medications, coal dust, silicosis and byssinosis. When the cause is not identifiable it is referred to as idiopathic diffuse interstitial pulmonary fibrosis (27 Sep 1997) |
| idiopathic interstitial fibrosis | A progressive inflammatory condition starting with diffuse alveolar damage and resulting in fibrosis and honeycombing over a variable time period; also a common feature of collagen-vascular diseases. Synonym: fibrosing alveolitis, Hamman-Rich syndrome, idiopathic interstitial fibrosis. (05 Mar 2000) |
| interstitial | <anatomy> Pertaining to or situated between parts or in the interspaces of a tissue. Origin: L. Interstitialis, inter = between, sistere = to set (18 Nov 1997) |
| interstitial absorption | The removal of water or of substances in the interstitial fluid by the lymphatics. (05 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 cystitis | <pathology, urology> A chronic inflammatory condition of the bladder. The cause of interstitial cystitis is unknown, but occurs more commonly in females. Symptoms include difficulty urinating, pain on urination, urinary urgency and increased frequency of urination. (27 Sep 1997) |
| interstitial deletion | Deletion that does not involve the terminal parts of a chromosome. (05 Mar 2000) |
| interstitial disease | A disease occurring chiefly in the connective-tissue framework of an organ, the parenchyma suffering secondarily. (05 Mar 2000) |
| interstitial emphysema | Presence of air in the pulmonary tissues consequent upon rupture of the air cells, presence of air or gas in the connective tissue. (05 Mar 2000) |
| interstitial fluid | The fluid in spaces between the tissue cells, constituting about 16% of the weight of the body; closely similar in composition to lymph. Synonym: tissue fluid. (05 Mar 2000) |
| interstitial gastritis | Inflammation of the stomach involving the submucosa and muscle coats. (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) |
