| insulin receptor substrate-1 protein | <chemical> Amino acid sequence given in first source; a 180 kD protein that contains multiple phosphorylated tyrosine residues after insulin stimulation; human and rat forms (hirs-1 and irs-1) are homologous Synonym: insulin receptor substrate-1-like protein, irs-1 protein, irs-1 gene product, hirs-1 protein, hirs-1 gene product, insulin receptor substrate 1, insulin receptor substrate-1 (05 Dec 1998) |

| insulin resistance | Many people with noninsulin-dependent diabetes produce enough insulin, but their bodies do not respond to the action of insulin. This may happen because the person is overweight and has too many fat cells, which do not respond well to insulin. Also, as people age, their body cells lose some of the ability to respond to insulin. Insulin resistance is also linked to high blood pressure and high levels of fat in the blood. Another kind of insulin resistance may happen in some people who take insulin injections. They may have to take very high doses of insulin every day (200 units or more) to bring their blood glucose (sugar) down to the normal range. (09 Oct 1997) |
| insulin shock | A severe condition that occurs when the level of blood glucose (sugar) drops quickly. The signs are shaking, sweating, dizziness, double vision, convulsions, and collapse. Insulin shock may occur when an insulin reaction is not treated quickly enough. See: hypoglycaemia. (09 Oct 1997) |
| insulin shock treatment | Formerly used treatment for serious mental disorders in which the patient was given insulin to induce a seizure; supplanted by electroshock therapy. (05 Mar 2000) |
| insulin-stimulating peptide | <chemical> 71-amino acid containing peptide; corresponds to residues 115-143 and 144-184 of bovine serum albumin with the exception of a tyrosine insertion between residues 155 and 156; consists of two chains with mw 5000 and 3400 for each chain Synonym: h-isp, insulin-stimulating protein (05 Dec 1998) |
| insulin unit | The activity contained in 1/22 mg of the international standard of zinc-insulin crystals. (05 Mar 2000) |
| insulin zinc suspension | A sterile buffered suspension with zinc chloride, containing 40 or 80 units per ml; the solid phase of the suspension consists of a mixture of 7 parts of crystalline insulin and 3 parts of amorphous insulin. Synonym: lente insulin. (05 Mar 2000) |
| extended insulin zinc suspension | A long-acting insulin suspension, obtained from beef, with an approximate time of onset of 7 hours and a duration of action of 36 hours. Synonym: crystalline insulin zinc suspension. (05 Mar 2000) |
| ultralente insulin | A form of zinc precipitated insulin in suspension in which the particle size is large, and thus release into the bloodstream after subcutaneous injection is slow; it can be mixed with other insulins having different particle sizes to achieve different durations of activity. Can be derived from porcine, bovine, or genetically engineered human type. (05 Mar 2000) |
| lente insulin | A sterile buffered suspension with zinc chloride, containing 40 or 80 units per ml; the solid phase of the suspension consists of a mixture of 7 parts of crystalline insulin and 3 parts of amorphous insulin. Synonym: lente insulin. (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) |
| acid loading test | <nephrology> This is a test used in the diagnosis of renal tubular acidosis. The patient takes ammonium chloride capsules for 3 days to acidify the blood (lower blood pH). A sample of the urine and the blood is then collected and the results are interpreted. (27 Sep 1997) |
