| tPA | tissue Plasminogen Activator |
| AT | abdominal thrusts; achievement test; Achilles tendon; Achard-Thiers [syndrome]; adaptive thermogenes... |
| ATE | acute toxic encephalopathy; adipose tissue extract; autologous tumor extract |
| BALT | broncho-alveolar lavage fluid; bronchus-associated lymphoid tissue |
| mesenchymal tissue | Embryonic connective tissue. See: mesenchyme. (05 Mar 2000) |
|---|---|
| peripheral lymphoid tissue | Secondary lymphoid tissue, not necessarily located peripherally. See: lymphoid tissue. (18 Nov 1997) |
| mesonephric tissue | Intermediate mesoderm situated in the thoracic and lumbar regions of the embryo or foetus; it evolves into the mesonephros and associated structures. (05 Mar 2000) |
| metanephrogenic tissue | Tissue derived from the intermediate mesoderm caudal to mesonephric levels and concerned with the formation of the nephrons of the metanephros. (05 Mar 2000) |
| ground tissue | <plant biology> Plant tissues other than those of the vascular system and the dermal tissues. Composed of relatively undifferentiated cells. (18 Nov 1997) |
| guided tissue regeneration | The repopulating of the periodontium, after treatment for periodontal disease. Repopulation is achieved by guiding the periodontal ligament progenitor cells to reproduce in the desired location by blocking contact of epithelial and gingival connective tissues with the root during healing. This blocking is accomplished by using synthetic membranes or collagen membranes. (12 Dec 1998) |
| chondroid tissue | In an adult, tissue resembling cartilage. In an embryo, an early stage in cartilage formation. Synonym: fibrohyaline tissue, pseudocartilage. (05 Mar 2000) |
| gut-associated lymphoid tissue | <physiology> Peripheral lymphoid organ consisting of lymphoid tissue associated with the gut (Peyer's patches, tonsils, mesenteric lymph nodes and the appendix). It is especially rich in B-cells and is responsible for localised immunity to pathogens such as bacteria, viruses, and parasites. (20 Sep 2002) |
| chromaffin tissue | Tissue in medulla of adrenal gland containing two populations of cells, one producing adrenaline, the other noradrenaline. The catecholamine is associated with carrier proteins (chromogranins) in membrane vesicles (chromaffin granules). (18 Nov 1997) |
| rubber tissue | A thin sheet of rubber used as a cover in surgical dressings. (05 Mar 2000) |
| mixed connective tissue disease | <syndrome> A syndrome with overlapping clinical features of systemic lupus erythematosus, scleroderma, polymyositis, and Raynaud's phenomenon. The disease is differentially characterised by high serum titres of antibodies to ribonuclease-sensitive extractable (saline soluble) nuclear antigen (nuclear ribonucleoprotein) and a speckled epidermal nuclear staining pattern on direct immunofluorescence. A more modern term for this condition is the undifferentiated connective tissues disease. (22 Sep 2002) |
| Mohs' fresh tissue chemosurgery technique | Chemosurgery in which superficial cancers are excised after fixation in vivo. (05 Mar 2000) |
| compression of tissue | The property of tissue that permits it to be moved from an initial or relaxed position or form. Synonym: compression of tissue. (05 Mar 2000) |
| platelet tissue factor | <haematology> Traditional name for substance in plasma that converts prothrombin to thrombin. Now known not to be a single substance. (See thrombin). (18 Nov 1997) |
| mucous connective tissue | A type of connective tissue little differentiated beyond the mesenchymal stage; its ground substance of glycoproteins is abundant and contains fine collagenous fibres and fibroblasts; in its most characteristic form, it appears in the umbilical cord as Wharton's jelly. Synonym: gelatinous tissue. (05 Mar 2000) |
