| insulin injection | A preparation that may contain 20, 40, 80, 100, or 500 USP insulin units per ml, although the trend is toward standardizing all insulin preparations at 100 units per ml; it is administered subcutaneously, occasionally intravenously, and has a rapid onset of action, has a brief duration (5 to 7 hours), and is compatible for mixing with long-acting insulin preparations; used in the treatment of diabetic acidosis and insulin coma. Synonym: regular insulin injection. (05 Mar 2000) |
| intracytoplasmic sperm injection | <gynaecology> The direct injection of a single sperm into an egg. (09 Oct 1997) |
| intramuscular injection | <technique> A technique to deliver a medication into muscle tissue for its eventual absorption into the systemic circulation. Smaller volume intramuscular injections may be given into the deltoid, but larger volumes are usually given into the gluteus muscle. (27 Sep 1997) |
| 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) |
| 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) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| acetone test | A test for ketonuria; the suspected urine is shaken up with a few drops of sodium nitroprusside, and strong ammonia water is then gently poured over the mixture; if acetone is present, a magenta ring forms at the line of contact; tablets containing sodium nitroprusside and alkali are now more commonly used. (05 Mar 2000) |
| achievement test | A standardised test used to measure acquired learning, e.g., competence in a specific subject area such as reading or arithmetic, in contrast to an intelligence test which is a useful index of potential ability or learning. (05 Mar 2000) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
