| EFP | early follicular phase; effective filtration pressure; endoneural fluid pressure |
|---|---|
| FFAP | free fatty acid phase |
| G0 | quiescent phase of cells leaving the mitotic cycle |
| G1 | presynthetic gap [phase of cells prior to DNA synthesis] |
| G2 | postsynthetic gap [phase of cells following DNA synthesis] |
| collagen-vascular diseases | A group of generalised disease's affecting connective tissue and frequently characterised by fibrinoid necrosis or vasculitis; in some collagen disease's, auto-immunization, particularly antinuclear antibodies, has been shown and circulating immune complexes are found. The term is not entirely acceptable because there is no evidence that collagen is primarily involved; "collagen" was once synonymous with "connective tissue" rather than describing a specific fibrinous protein in that tissue. See: connective-tissue diseases. (05 Mar 2000) |
|---|---|
| muscle, smooth, vascular | The nonstriated, involuntary muscle tissue of blood vessels. (12 Dec 1998) |
| Haller's vascular tissue | <anatomy> The outer portion of the choroid of the eye containing the largest blood vessels. Synonym: lamina vasculosa choroideae, Haller's vascular tissue, uvaeformis, vascular layer of choroid coat of eye, vascular layer. (05 Mar 2000) |
| skin diseases, vascular | Skin diseases affecting or involving the cutaneous blood vessels and generally manifested as inflammation, swelling, erythema, or necrosis in the affected area. (12 Dec 1998) |
| neoplasms, vascular tissue | Neoplasms composed of vascular tissue. This concept does not refer to neoplasms located in blood vessels. (12 Dec 1998) |
| dementia, vascular | An organic mental disorder caused by systemic vascular disease such as arteriosclerotic changes in the vessels, valvular heart disease, hypertension, etc., and resulting in cerebral vascular disease with dementia. (12 Dec 1998) |
| systemic vascular resistance | An index of arteriolar compliance or constriction throughout the body; equal to the blood pressure divided by the cardiac output. (05 Mar 2000) |
| encephalotrigeminal vascular syndrome | <syndrome> Angiomatosis of the brain accompanied by nevi in the trigeminal area. See: Sturge-Weber syndrome. (05 Mar 2000) |
| endothelium, vascular | Single pavement layer of cells which line the luminal surface of the entire vascular system and regulate the transport of macromolecules and blood components from interstitium to lumen; this function has been most intensively studied in the blood capillaries. (12 Dec 1998) |
| Zinn's vascular circle | <anatomy, nerve> A network of branches of the short ciliary arteries on the sclera around the point of entrance of the optic nerve. Synonym: circulus vasculosus nervi optici, circulus arteriosus halleri, circulus zinnii, Haller's circle, Zinn's corona, Zinn's vascular circle. (05 Mar 2000) |
| accelerated phase of leukaemia | Refers to chronic myelogenous leukaemia that is progressing. The number of immature, abnormal white blood cells in the bone marrow and blood is higher than in the chronic phase, but not as high as in the blast phase. (12 Dec 1998) |
| acceleration phase | <cell biology, cell culture> A period of increasing growth before the log phase in a culture of microbes. After the culture is started on a medium, at first there is no growth (the lag phase) and then the microbes start to gradually grow (acceleration phase) until they reach a constant maximum rate of growth (log phase). (15 Jan 1998) |
| acute-phase protein | <haematology> These plasma proteins (in addition to fibrinogen) increase 25% or more in response to inflammation and injury are under direct control of interleukin-6 (IL-6) (hepatocyte-stimulating factor). Other proteins which increase are ceruloplasmin, C3 and C4 which increase 50% or more; alpha-1 acid glycoprotein, alpha-1 antitrypsin, haptoglobin and fibrinogen (the major determinant of viscosity 1 ) which increase two- to fourfold; C-reactive protein (CRP) and serum amyloid A which increase several hundred-fold. Despite long-held clinical opinion to the contrary, available data indicate that neither ESR nor measurement of specific acute-phase reactants are useful in excluding underlying infection or inflammation regardless of the pretest probability. These proteins are secreted into the blood in increased or decreased quantities by hepatocytes in response to trauma, inflammation, or disease. They can serve as inhibitors or mediators of the inflammatory processes. Certain acute-phase proteins have been used to diagnose and follow the course of diseases or as tumour markers. See also: amyloid, c-reactive protein, erythrocyte sedimentation rate, viscosity. (25 Jun 1999) |
| acute-phase reaction | <immunology, rheumatology> Refers to the changes in synthesis of certain proteins within the serum during an inflammatory response, which provides rapid protection for the host against microorganisms via non-specific defense mechanisms. It consists of fever, an increase in inflammatory humoral factors, and an increased synthesis by hepatocytes of a number of proteins or glycoproteins usually found in the plasma; the reaction is mediated by endogenous pyrogens, the hypothalamus, adrenal hormones, and other factors.

| anal phase | In psychoanalytic personality theory, the stage of psychosexual development, occurring when a child is between 1 and 3 years, during which activities, interests, and concerns are centreed around the anal zone. (05 Mar 2000) |
