Secretion of Insulin and Glucagon November 2007

چکیده
Coordination of metabolism in and between our various tissues is the cornerstone of life. The activities of many of the steps in metabolism are controlled by circulating hormones, the most prominent of these being the pancreatic hormones insulin and glucagon. Control of the rates of secretion of these two peptides is necessary to assure a stable inner milieu, allowing us to adjust our metabolism to meet the stresses of life. Meals, running after the bus, rest and sleep; all require adjustments in metabolic rates to allow us to function. Many of my readers perhaps associate insulin with sugar metabolism and diabetes. It is important to realize insulin, glucagon and many other hormones also control protein and lipid metabolism, feelings of hunger and satiation as well as sugar metabolism.

Treatment effect of GABA on improve type one diabetes in NOD mice
Introduction: Gama amino butyric acid (GABA) is the major inhibitory neurotransmitter in the mammalian nervous system. The concentration of GABA and the number of GABA cell secretion decrease in diabetic patient and experimental diabetes model. The reported effects of GABA activation on insulin secretion from beta cells have been controversial. In this study we investigated if GABA administr...

In order to investigate the relationship between insulin to glucagon ratio and metabolic factors in transitional period of dairy cows, 28 cows heifers with body condition score of 3.25- 3.75 were selected. Dairy cows received close up diet, from 21 days prepartum until parturition and lactation diet according to nutritional requirements after parturition. Blood was sampled at 10 days before and...
متن کاملZinc, not insulin, regulates the rat alpha-cell response to hypoglycemia in vivo.
The intra-islet insulin hypothesis proposes that the decrement in beta-cell insulin secretion during hypoglycemia provides an activation signal for alpha-cells to release glucagon. A more recent hypothesis proposes that zinc atoms suppress glucagon secretion via their ability to open alpha-cell ATP-sensitive K(+) channels. Since insulin binds zinc, and zinc is co-secreted with insulin, we teste...
متن کاملSulfonylurea compounds uncouple the glucose dependence of the insulinotropic effect of glucagon-like peptide 1.
Glucagon-like peptide (GLP)-1 mimetics have been reported to cause hypoglycemia when combined with sulfonylureas. This study investigated the impact of tolbutamide on the glucose dependence of the GLP-1-mediated effects on insulin, glucagon, and somatostatin secretion in the in situ perfused rat pancreas. At 3 mmol/l glucose, GLP-1 alone did not augment insulin secretion, whereas tolbutamide al...
متن کاملEnhanced Glycemic Responsiveness to Epinephrine in Insulin - dependent Diabetes Mellitus
To determine if the enhanced glycemic response to epinephrine in patients with insulin-dependent diabetes mellitus (IDDM) is the result of increased adrenergic sensitivity per se, increased glucagon secretion, decreased insulin secretion, or a combination of these, plasma epinephrine concentration-response curves were determined in insulin-infused (initially euglycemic) patients with IDDM and n...
