| anti-insulin antibody | A serologic blood test that is used to detect antibodies to insulin. This test is performed in insulin dependent diabetics who exhibit insulin resistance. The presence of antibodies denotes a positive result. (27 Sep 1997) |

| biphasic insulin | <protein> A type of insulin that is a mixture of intermediate- and fast-acting insulin. (09 Oct 1997) |
| receptors, insulin | Cell surface proteins that bind insulin and trigger intracellular changes which influence the behaviour of cells. The best understood physiological consequence of insulin receptor activation is increased transport of glucose into most cells, which controls the rate of carbohydrate metabolism. The insulin receptor is a multifunctional protein complex that has intrinsic tyrosine kinase activity and is capable of autophosphorylation. (12 Dec 1998) |
| receptors, insulin-like-growth factor I | Specific proteins on or in cells to which insulin-like growth factor I (somatomedin c) binds and thereby modifies the function of the cells. These receptors contain transmembrane and cytosolic domains, bind igf-I preferentially, and have high-affinity sites for igf-II. The alpha-subunit has a mw of 130 kD and the beta subunit possesses tyrosine kinase activity. (12 Dec 1998) |
| receptors, insulin-like-growth-factor II | Specific proteins on or in cells to which insulin-like growth factor II and mannose-6-phosphate bind and thereby modify the function of the cells. These receptors have a mw of 250 kD and possess no tyrosine kinase activity. (12 Dec 1998) |
| regular insulin | A rapidly acting form of insulin which is a clear solution and may be administered intravenously as well as subcutaneously; may be mixed with longer acting forms of insulin to extend the duration of effect. Onset of effect occurs in 1/2 to 1 hour, peak effects are observed in 2 to 3 hours, and the duration of effect is about 5 to 7 hours. Synonym: globin insulin. (05 Mar 2000) |
| regular 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) |
| globin insulin | A rapidly acting form of insulin which is a clear solution and may be administered intravenously as well as subcutaneously; may be mixed with longer acting forms of insulin to extend the duration of effect. Onset of effect occurs in 1/2 to 1 hour, peak effects are observed in 2 to 3 hours, and the duration of effect is about 5 to 7 hours. Synonym: globin insulin. (05 Mar 2000) |
| semilente insulin | Sterile suspension of insulin in buffered water for injection, modified by the addition of zinc chloride such that the solid phase of the suspension is amorphous; it contains 40 or 80 units per ml; the duration of action is equivalent to that of insulin injection. Synonym: amorphous insulin zinc suspension, semilente insulin. (05 Mar 2000) |
| non-insulin-dependent diabetes mellitus | <disease> An often mild form of diabetes mellitus of gradual onset, usually in obese individuals over age 35; absolute plasma insulin levels are normal to high, but relatively low in relation to plasma glucose levels; ketoacidosis is rare, but hyperosmolar coma can occur; responds well to dietary regulation and/or oral hypoglycaemic agents, but diabetic complications and degenerative changes can develop. (05 Mar 2000) |
| nonsuppressible insulin-like activity | A blood protein (nsila) which mimics the biological activity of insulin in serum, but is not suppressed by insulin antibodies. During acid-ethanol extraction of cohn fraction III, 10% of the activity is found in the supernatant (nsila-s) and the remaining activity in the precipitate (nsila-p). The latter is a large molecular compound, much less stable than the soluble fraction. Nsila-s is a more potent growth factor than insulin and exhibits sulfation activity. (12 Dec 1998) |
| NPH insulin | isophane insulin |
| diabetes mellitus, insulin-dependent | Diabetes mellitus characterised by insulin deficiency, sudden onset, severe hyperglycaemia, rapid progression to ketoacidosis, and death unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence. (12 Dec 1998) |
| diabetes mellitus, non-insulin-dependent | Diabetes characterised by the ability to survive without ketoacidosis in the absence of insulin therapy. It is usually of slow onset and patients exhibit a tendency to obesity. (12 Dec 1998) |
| insulin | <drug, growth factor, hormone> A polypeptide hormone (bovine insulin, 5780D) found in both vertebrates and invertebrates. Secreted by the _ cells of the pancreas in response to high blood sugar levels, it induces hypoglycaemia. Defective secretion of insulin is the cause of diabetes mellitus. Insulin is also a mitogen, has sequence homologies with other growth factors and is a frequent addition to cell culture media for demanding cell types. (18 Nov 1997) |
