| cellular pathology | The interpretation of diseases in terms of cellular alterations, i.e., the ways in which cells fail to maintain homeostasis, sometimes used as a synonym for cytopathology. (05 Mar 2000) |
|---|---|
| cellular polyp | A polyp that consists of benign neoplastic tissue derived from glandular epithelium. Synonym: cellular polyp, polypoid adenoma. (05 Mar 2000) |
| cellular respiration | <biochemistry> The conversion within the cell of nutrients (such as sugar molecules) into chemical energy in the form of ATP, by reacting the food with oxygen (O2) until the food has completely been degraded into carbon dioxide and H2O. (09 Oct 1997) |
| cellular retinoic acid binding protein | <protein> A cytoplasmic fatty acid binding protein that acts as an initial receptor for the putative morphogen, retinoic acid. (18 Nov 1997) |
| cellular slime mould | See: Acrasidae. (18 Nov 1997) |
| cellular tumour | A tumour composed mainly of closely packed cells. (05 Mar 2000) |
| immunity, cellular | Those manifestations of the immune response which are mediated by antigen-sensitised T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role. (12 Dec 1998) |
| air embolism | <physiology> A serious condition that results when air (in the form of bubbles) invades the blood vessels causing disruption of normal blood flow. (06 Aug 1998) |
| amniotic fluid embolism | Obstruction and constriction of pulmonary blood vessels by amniotic fluid entering the maternal circulation, causing obstetric shock. See: amniotic fluid syndrome. (05 Mar 2000) |
| arterial embolism | <cardiology, physiology> A sudden interruption in arterial blood flow to an organ or body part (extremity). The blockage is caused by a blot clot or atherosclerotic plaque that has moved through the arterial circulation from one position to another. The resulting mechanism is the same regardless of cause or location. Oxygen deprivation to the tissues distal to the occlusion become ischaemic and die (necrosis). Atrial fibrillation is a risk factor for arterial embolism due to the release of blood clots from the fibrillating heart. Blood vessel injury and increased levels of platelets can also be a risk for arterial embolism. Symptoms vary with location, but pain, coolness to an extremity and a absent or diminished pulse are common in the case of an extremity embolism. Treatment is often surgical or involves the use of blood clot dissolving medications (for example streptokinase) delivered selectively to the site of the blockage. (17 Oct 1997) |
| atheroma embolism | Embolism of lipid debris from an ulcerated atheromatous deposit, generally from a large artery to small arterial branches; it is usually small and rarely causes infarction. Synonym: atheroma embolism. (05 Mar 2000) |
| bland embolism | Embolism by simple nonseptic material. (05 Mar 2000) |
| bone marrow embolism | Obstruction of a vessel by bone marrow, usually following fracture of a bone. (05 Mar 2000) |
| gas embolism | <physiology> A serious condition that results when air (in the form of bubbles) invades the blood vessels causing disruption of normal blood flow. (06 Aug 1998) |
| pantaloon embolism | Synonym: saddle embolism. (05 Mar 2000) |
