| endothelin-valine-generating endopeptidase | <enzyme> Cleaves big endothelin between val22 and asn23 Registry number: EC 3.4.21.- Synonym: big-et-ge (26 Jun 1999) |

| endothelins | 21-amino-acid peptides produced by vascular endothelial cells and functioning as potent vasoconstrictors. The endothelin family consists of three members, endothelin-1, endothelin-2, and endothelin-3. All three peptides contain 21 amino acids, but vary in amino acid composition. The three peptides produce vasoconstrictor and pressor responses in various parts of the body. However, the quantitative profiles of the pharmacological activities are considerably different among the three isopeptides. (12 Dec 1998) |
| 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) |
| endotheliochorial placenta | A placenta in which the chorionic tissue penetrates to the endothelium of the maternal blood vessels. (05 Mar 2000) |
| endotheliocyte | 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) |
| endothelioid | Resembling endothelium. (05 Mar 2000) |
| endothelioma | <oncology, tumour> A tumour (usually benign) which is formed from tissues of the endothelium. (09 Oct 1997) |
| endotheliosis | Proliferation of endothelium. (05 Mar 2000) |
| endotheliotoxin | A poison that causes haemorrhages (internal bleeding) by attacking the endothelium (inner lining) of small blood vessels. (09 Oct 1997) |
| endothelium | <pathology> The layer of epithelial cells that lines the cavities of the heart and of the blood and lymph vessels and the serous cavities of the body, originating from the mesoderm. Origin: Gr. Thel = nipple (18 Nov 1997) |
| endothelium camerae anterioris | A single layer of large, squamous cells that covers the posterior surface of the cornea. Synonym: endothelium camerae anterioris. (05 Mar 2000) |
| endothelium derived relaxation factor | <biochemistry> This compound is produced from L arginine by the enzyme nitric oxide synthase. Acts as a potent vasorelaxant via elevation of intracellular cGMP in vascular smooth muscle. Synthesis of nitric oxide is not confined to endothelium, isoforms of nitric oxide synthase are also found in brain, neutrophils and platelets. Synonym: endothelium derived relaxation factor. Acronym: NO (29 Dec 1997) |
| endothelium of anterior chamber | A single layer of large, squamous cells that covers the posterior surface of the cornea. Synonym: endothelium camerae anterioris. (05 Mar 2000) |
| endothelium, corneal | Single layer of large flattened cells covering the surface of the cornea. (12 Dec 1998) |
| endothelium, lymphatic | Unbroken cellular lining (intima) of the lymph vessels (e.g., the high endothelial lymphatic venules). It is more permeable than vascular endothelium, lacking selective absorption and functioning mainly to remove plasma proteins that have filtered through the capillaries into the tissue spaces.
