| intrathecal injection | Injection of drugs into the spinal fluid to prevent or treat CNS leukaemia or lymphoma. (13 Nov 1997) |
|---|---|
| intravenous injection | <pharmacology> The giving of drugs into a vein through a syringe. (30 Mar 1998) |
| intraventricular injection | The introduction of materials for diffusion throughout the ventricular and subarachnoid space by means of ventricular puncture. (05 Mar 2000) |
| test injection | Intravenous injection of a few milliliters of radiographic contrast medium to screen for allergic or idiosyncratic responses. (05 Mar 2000) |
| jet injection | Hypodermic injection of drugs by a jet injector. (05 Mar 2000) |
| Z-tract injection | A technique in which the skin and subcutaneous tissue are displaced laterally before inserting the needle intramuscularly; used to prevent leakage along the track of the needle and consequent tissue irritation. (05 Mar 2000) |
| flow injection analysis | The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device. (12 Dec 1998) |
| lactated Ringer's injection | A sterile solution of calcium chloride, potassium chloride, sodium chloride, and sodium lactate in water for injection; used intravenously as a systemic alkaliser and a fluid and electrolyte replenisher. (05 Mar 2000) |
| acceptor site | The ribosomal binding site for the aminoacyl-tRNA during protein synthesis. (05 Mar 2000) |
| acceptor splicing site | Boundary between the right end of an intron and the left end of the adjacent exon. Synonym: acceptor splicing site. (05 Mar 2000) |
| active site | <chemistry> A specific region of an enzyme where a substrate binds and catalysis takes place (binding site). (06 May 1997) |
| allosteric site | A specific site on a multi-subunit enzyme or other protein that is not the substrate binding site, but that when reversibly bound by an effector, induces a conformational change in the protein, altering its catalytic or binding properties. (12 Dec 1998) |
| amidation site | <molecular biology> A C terminus consensus sequence, required for C terminus amidation of peptides. Consensus is glycine, followed by 2 basic amino acids (arg or lys). (18 Nov 1997) |
| antibody combining site | <immunology> In immune network theory, an idiotope, an antigenic site of an antibody that is responsible for that antibody binding to an antigenic determinant (epitope). Also used of the site on a ligand molecule to which a cell surface receptor binds. (18 Nov 1997) |
| antigen-binding site | <immunology> In immune network theory, an idiotope, an antigenic site of an antibody that is responsible for that antibody binding to an antigenic determinant (epitope). Also used of the site on a ligand molecule to which a cell surface receptor binds. (18 Nov 1997) |
