insulin /in·su·lin/ (in´sdbobr-lin)

1. a protein hormone formed from proinsulin in the beta cells of the pancreatic islets of Langerhans. The major fuel-regulating hormone, it is secreted into the blood in response to a rise in concentration of blood glucose or amino acids. Insulin promotes the storage of glucose and the uptake of amino acids, increases protein and lipid synthesis, and inhibits lipolysis and gluconeogenesis.

Insulin. The precursor proinsulin is cleaved internally at two sides (arrows) to yield insulin and C peptide.

2. a preparation of insulin, either of porcine or bovine origin or a recombinant form with sequence the same as or similar to that in humans, used in the treatment of diabetes mellitus; classified as rapid-acting, intermediate-acting, or long-acting on the basis of speed of onset and duration of activity.

3. regular insulin; a rapid-acting, unmodified form of insulin prepared from crystalline bovine or porcine insulin.

Insulin

A hormone secreted by the pancreas in response to high blood sugar levels that induces hypoglycemia. Insulin regulates the body's use of glucose and the levels of glucose in the blood by acting to open the cells so that they can intake glucose.

insulin

[in′səlin]

Etymology: L, insula, island

1 a naturally occurring polypeptide hormone secreted by the beta cells of the islets of Langerhans in the pancreas in response to increased levels of glucose in the blood as well as to the parasympathetic nervous system and other stimuli. The hormone acts to regulate the metabolism of glucose and the processes necessary for the intermediary metabolism of fats, carbohydrates, and proteins. Insulin lowers the blood glucose level and promotes transport of glucose into the muscle cells and other tissues. Inadequate secretion of insulin causes elevated blood glucose and triglyceride levels and ketonemia, as well as the characteristic signs of diabetes mellitus, including increased desire to eat, excessive thirst, increased urination, and eventually lethargy and weight loss. Uncorrected severe deficiency of insulin is incompatible with life. Normal findings of insulin assay in adults are levels of 5 to 24 mmU/mL.

2 a pharmacologic preparation of the hormone administered in treating diabetes mellitus. The various preparations of insulin available for prescription vary in onset, intensity, and duration of action. Animal source insulins, pork and beef, have been discontinued in the U.S. market. Human insulin is derived by recombinant DNA technology and is termed quick acting, intermediate acting, or long acting. Most replacement insulin is given by subcutaneous injection in individualized dosage schedules and insulin pumps, but insulin also can be replaced intravenously. Adverse reactions include hypoglycemia and insulin shock that result from excess dosage and hyperglycemia and diabetic ketoacidosis from inadequate dosage. Fever, stress, infection, pregnancy, surgery, and hyperthyroidism may significantly increase insulin requirements; liver disease, hypothyroidism, vomiting, and renal disease may decrease them. Blood tests for glucose and ketones are performed to determine the need for adjustment of the dosage or of the schedule of administration. See also human insulin.

insulin

a double-chain peptide hormone formed from proinsulin in the beta cells of the pancreatic islets of Langerhans. Insulin promotes the storage of glucose and the uptake of amino acids, increases protein and lipid synthesis, and inhibits lipolysis and gluconeogenesis.

The secretion of endogenous insulin is a response of the beta cells to a stimulus. The primary stimulus is glucose; others are amino acids, particularly leucine, and the 'gut hormones', such as secretin, pancreozymin and gastrin. These chemicals play an important role in maintaining normal blood glucose levels by triggering the release of insulin after ingestion of a meal.

Commercially prepared insulin is available in various types, which differ in the speed with which they act and in the duration of their effectiveness. There are three main groups: rapid acting (regular or semilente), intermediate acting (isophane suspension or NPH, zinc suspension or lente), and long acting (protamine zinc suspension or PZI, or ultralente). Mixtures are also marketed.

insulin deficiency

diabetes mellitus.

insulin-dextrose therapy

a combination used in emergencies to lower blood potassium levels in acute hypoadrenocorticism.

insulin:glucagon ratio

ratio of insulin to glucagon; thought to determine the predominance of the action of one hormone over the other.

insulin:glucose ratio

a comparison of simultaneously obtained blood levels of immunoreactive insulin and plasma glucose. An increased ratio suggests an insulin-secreting tumor of the pancreas. A modification is the amended insulin:glucose ratio, based on the calculation:

$$\vskip13.5pt{\rm {serum\ insulin (\rmmu U/ml)\times100} \over {\rm plasma \ glucose (mg/dl) - 30}$$

immunoreactive insulin

radioimmunoassay methods are used in determining blood levels of insulin. Increased levels are found with hypoglycemia caused by functional islet cell tumors.

insulin pump

a device consisting of a syringe filled with a predetermined amount of short-acting insulin, a plastic cannula and a needle, and a pump that periodically delivers the desired amount of insulin. Sometimes used in humans, but of limited application in animals.

insulin sensitivity test, insulin response test

used to differentiate diabetes mellitus from pituitary and adrenal diabetes. A test dose of exogenous insulin will produce a rapid and marked decrease in blood glucose if the pancreas is not secreting sufficient insulin. A much less dramatic response is produced if hyperglycemia is due to excessive secretion of either pituitary or adrenocortical hormones rather than insufficient insulin production.

insulin syringe

disposable syringe with a capacity of 1 ml or less and a fine gauge needle (27-29G) attached, and graduation markings corresponding to insulin units in standard preparations. Needles may also be treated to minimize pain on injection.

Patient discussion about Insulin purified beef.

Q. I've a chronic pain website & would love 2 get comments on how 2 make it better http://chronicpain.today.c

A. nice site! very useful! i liked the "freebies"...good idea. how about some links to videos about the subject? could be nice...

Q. When will a generic brand of insulin be available? The cost of insulin seems to be way too high... And with the ever rising population of diabetics, you'd think some other companies would jump unto the bandwagon with a cheaper insulin... what's up with that?

A. Unfortunately, as long as Eli Lilly has an effective monopoly on the American market and docs continue to perscribe the latest "flavor" of insulin, the situation is unlikely to change. Personally, I refuse to use Lilly's products (use Novo Nordisk insulin instead) and am still using the regular and NPH I was using 20 years ago... Also, because Type I diabetes tends to affect children, parents are naturally always seeking the next new thing. Doesn't make for an environment conducive to cheaper alternatives, which is a real shame for us all.

Q. is there an alternative for the Insulin shots? something less painful but yet effective as the old way?

A. Here is a good site on alternative insulin delivery: http://www.diabetes.org/for-parents-and-kids/diabetes-care/alternative-insulin.jsp Hope this helps.
