| endothelial cell | A thin, flattened cell, a layer of them lines the inside surfaces of body cavities, blood vessels, and lymph vessels, making up the endothelium. (09 Oct 1997) |
|---|---|
| endothelial cyst | A serous cyst whose sac is lined with endothelium. (05 Mar 2000) |
| endothelial dystrophy of cornea | Spontaneous loss of corneal endothelium leading to oedema of the corneal stroma and epithelium. (05 Mar 2000) |
| endothelial growth factors | These growth factors are soluble mitogens secreted by a variety of organs. The factors are a mixture of two single chain polypeptides which have affinity to heparin. Their molecular weight are organ and species dependent. They have mitogenic and chemotactic effects and can stimulate endothelial cells to grow and synthesise DNA. The factors are related to both the basic and acidic fibroblast growth factors but have different amino acid sequences. (12 Dec 1998) |
| endothelial leukocyte | Old term for a monocyte, a type of leukocyte thought to be derived from reticuloendothelial tissue. (05 Mar 2000) |
| endothelial-leukocyte adhesion molecule | 115,000 Mw molecule on the surface of endothelial cells that is involved in blood leukocyte attachment to vessel walls as well as emigration from the vessels into the tissues. (05 Mar 2000) |
| endothelial myeloma | A malignant primary bone tumour that arises most commonly in the first three decades of life. It is highly malignant (prone to spread) and often requires treatment with some combination of radiation therapy and chemotherapy. (27 Sep 1997) |
| endothelial relaxing factor | A molecule functioning as a neurotransmitter and produced by activated macrophages. It is capable of killing tumour cells, parasites, and intracellular bacteria. (05 Mar 2000) |
| endothelio-endothelial placenta | A placenta in which the endothelium of the maternal vessels comes in direct contact with the endothelium of the foetal vessels to form the placental barrier. (05 Mar 2000) |
| fuchs' endothelial dystrophy | Disorder caused by loss of endothelium of the central cornea. It is characterised by hyaline endothelial outgrowths on descemet's membrane, epithelial blisters, reduced vision, and pain. (12 Dec 1998) |
| blood pressure, high | High blood pressure (hypertension) is a repeatedly elevated blood pressure exceeding 140 over 90 mmHg. High blood pressure is also called the silent killer. Chronically high blood pressure can cause blood vessel changes in the back of the eye (retina), thickening of the heart muscle, kidney failure, and brain damage. No specific cause for high blood pressure is found in 95% of patients. High blood pressure is treated with salt restriction, regular aerobic exercise, and medications. (12 Dec 1998) |
| blood sugar, high | Elevated levels of blood glucose (hyperglycaemia) can be found in a number of conditions. The hyperglycaemia leads to spillage of glucose into the urine, hence the term sweet urine. (Diabetes mellitus means sweet urine. ) (12 Dec 1998) |
| cardiac output, high | A state of elevated cardiac output. Conditions that lower peripheral vascular resistance, such as anaemia, arteriovenous fistulas, thyrotoxicosis, and pregnancy, are among the most important factors augmenting the venous return and therefore elevating cardiac output. Increased cardiac output also occurs in muscular exercise, fever, and severe anoxia. (12 Dec 1998) |
| radiotherapy, high-energy | Radiotherapy using high-energy (megavolt or higher) ionizing radiation. Types of radiation include gamma rays, produced by a radioisotope within a teletherapy unit; X-rays, electrons, protons, alpha particles (helium ions) and heavy charged ions, produced by particle acceleration; and neutrons and pi-mesons (pions), produced as secondary particles following bombardment of a target with a primary particle. (12 Dec 1998) |
| mean higher high water | <marine biology> The average height of the higher high water over a 19-year period. For shorter periods of observation, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. (09 Oct 1997) |
