| home infusion therapy | Use of any infusion therapy on an ambulatory, outpatient, or other non-institutionalised basis. (12 Dec 1998) |
| infusion | The therapeutic introduction of a fluid other than blood, as saline solution, solution, into a vein. (18 Nov 1997) |
| infusion-aspiration drainage | A type of drainage in which antibiotics are continuously infused into a cavity at the same time fluid is being drained (aspirated) from the cavity. Synonym: drip-suck irrigation. (05 Mar 2000) |
| infusion graft | Transplantation by injection of a suspension of cells. (05 Mar 2000) |
| infusion pumps | Fluid propulsion systems driven mechanically, electrically, or osmotically that are used to inject (or infuse) over time agents into a patient or experimental animal; used routinely in hospitals to maintain a patent intravenous line, to administer antineoplastic agent and other drugs in thromboembolism, heart disease, diabetes mellitus (insulin infusion systems is also available), and other disorders. (12 Dec 1998) |
| infusion pumps, implantable | Implanted fluid propulsion systems with self-contained power source for providing long-term controlled-rate delivery of drugs such as chemotherapeutic agents or analgesics. Delivery rate may be externally controlled or osmotically or peristaltically controlled with the aid of transcutaneous monitoring. (12 Dec 1998) |
| insulin infusion systems | Portable or implantable devices for infusion of insulin. Includes open-loop systems which may be patient-operated or controlled by a pre-set program and are designed for constant delivery of small quantities of insulin, increased during food ingestion, and closed-loop systems which deliver quantities of insulin automatically based on an electronic glucose sensor. (12 Dec 1998) |
| intravenous infusion | <pharmacology> The giving of antibiotics, blood products, anti-cancer drugs or nutrients into a patients vein over a prolonged period of time. (30 Mar 1998) |
| acidic amino acid | An Amino acid with a second acid moiety, e.g., glutamic acid, aspartic acid, cysteic acid. (05 Mar 2000) |
| activated amino acid | The product formed by the condensation of the acyl radical of an amino acid and adenosine 5'-monophosphate (originally in the form of adenosine 5'-triphosphate, with elimination of a pyrophosphoric group). Formed in the first step of protein biosynthesis. Synonym: activated amino acid. (05 Mar 2000) |
| alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid | <chemical> Alpha-amino-2,3-dihydro-5-methyl-3-oxo-4-isoxazolepropanoic acid. An ibotenic acid homolog and glutamate agonist. The compound is the defining agonist for the ampa subtype of glutamate receptors (receptors, ampa). It has been used as a radionuclide imaging agent but is more commonly used as an experimental tool in cell biological studies. Pharmacological action: excitatory amino acid agonists. Chemical name: 4-Isoxazolepropanoic acid, alpha-amino-2,3-dihydro-5-methyl-3-oxo- (12 Dec 1998) |
| alpha-amino acid | Typically, an amino acid of the general formula R-CHNH2-COOH (i.e., the NH2 in the a position); the l forms of these are the hydrolysis products of proteins. In rarer usages, this class of molecules also includes alpha-amino phosphoric acids and alpha-aminosulfonic acids. (05 Mar 2000) |
| alpha-amino acid esterase | <enzyme> Converts alpha-amino acid esters and water to alpha-amino acids and alcohol Registry number: EC 3.1.1.43 Synonym: alpha-amino acid ester hydrolase (26 Jun 1999) |
