| angiosperms | Any member of the more than 250,000 species of flowering plants (division magnoliophyta) having roots, stems, leaves, and well-developed conductive tissues (xylem and phloem). Angiosperms are often differentiated from gymnosperms by their production of seeds within a closed chamber (the ovary). The magnoliophyta division is composed of two classes, the monocotyledons (liliopsida) and dicotyledons (magnoliopsida). (12 Dec 1998) |

| angiostrongylosis | Infection of animals and man with nematodes of the genus Angiostrongylus. Synonym: eosinophilic meningitis. (05 Mar 2000) |
| angiostrongylus | A genus of parasitic nematodes of the superfamily metastrongyloidea. Two species, angiostrongylus cantonensis and a. Vasorum, infest the lungs of rats and dogs, respectively. A. Cantonensis is transmissible to man where it causes frequently fatal infection of the central nervous system. (12 Dec 1998) |
| angiostrongylus cantonensis | A species of parasitic nematodes distributed throughout the pacific islands that infests the lungs of domestic rats. Human infection, caused by consumption of raw slugs and land snails, results in eosinophilic meningitis. (12 Dec 1998) |
| Angiostrongylus costaricensis | A nematode parasite of rats and other rodents in Central America, recently found to infect humans, where they localise in the mesenteric arteries; infective third-stage larvae have been found in the slug, Vaginulus plebeius. Synonym: Morerastrongylus costaricensis. (05 Mar 2000) |
| Angiostrongylus malaysiensis | Species of Angiostrongylus found in Malaysia, a common rodent parasite similar to Angiostrongylus cantonensis and an actual or potential agent of eosinophilic meningitis in that region. (05 Mar 2000) |
| Angiostrongylus vasorum | A species occurring in the pulmonary artery and, rarely, in the right ventricle of the dog and fox; thrombi may occur in the lungs, and hypertrophy of the heart and liver may result in ascites; affected animals suffer from dyspnea and occasionally may die from cardiac insufficiency. Synonym: Haemostrongylus vasorum. (05 Mar 2000) |
| angiotelectasis | Angiotelectasia Rarely used term for dilation of the terminal arterioles, venules, or capillaries. Origin: angio-+ G. Telos, end, + ektasis, a stretching out (05 Mar 2000) |
| angiotensin | <hormone> A family of oligopeptides ranging in size from angiotensin precursors with 14 amino acids to the active vasoconstrictor angiotensin II with 8 amino acids, or their analogs or derivatives. The amino acid content varies with the species and changes in that content produce antagonistic or inactive compounds. Angiotensinogen (renin substrate) is a 60 kD polypeptide released from the liver and cleaved in the circulation by renin to form the biologically inactive decapeptide angiotensin I. This is in turn cleaved to form active angiotensin II by Angiotensin-converting Enzyme (ACE). Angiotensin II causes contraction of vascular smooth muscle and thus raises blood pressure and stimulates aldosterone release from the adrenal glands. Angiotensin is finally broken down by angiotensinases. (12 Aug 2000) |
| angiotensin amide | <chemical> 1-l-asparagine-5-l-valine-angiotensin II. The octapeptide amide of bovine angiotensin II used to increase blood pressure by vasoconstriction. Pharmacological action: vasoconstrictor agents. Chemical name: Angiotensin II, 1-L-asparagine-5-L-valine- (12 Dec 1998) |
| angiotensin amide |
an amide derivative of angiotensin and a powerful vasoconstrictor and vasopressor, used in the treatment of certain hypotensive states; usually administered by slow intravenous infusion, and sometimes intramuscularly or subcutaneously.

| angiotensin II |
an octapeptide hormone formed by the action of angiotensin-converting enzyme (peptidyl-dipeptidase A) on a. I, chiefly in the lungs but also at other sites, including the blood vessel walls, uterus, and brain. It is a powerful vasopressor and stimulator of aldosterone secretion by the adrenal cortex, and it also functions as a neurotransmitter. Its vasopressor action raises blood pressure and diminishes fluid loss in the kidney by restricting blood flow.
