  • Title: Somatostatin. Its possible role in carbohydrate homeostasis and the treatment of diabetes mellitus.
    Author: Gerich JE.
    Journal: Arch Intern Med; 1977 May; 137(5):659-66. PubMed ID: 324423.
    Abstract:
    Somatostatin, a peptide inhibitor of growth hormone release originally isolated from the hypothalamus, is also present in D cells of pancreatic islets. Its ability to inhibit the secretion of insulin and glucagon suggests that it may be a local regulator of pancreatic A- and B-cell function. Studies using synthetic somatostatin have provided evidence that glucagon is a physiologically important hormone that exacerbates the consequences of insulin deficiency in human diabetes mellitus. The ability of somatostatin to diminish both fasting and post-prandial hyperglycemia and to forestall the development of ketoacidosis after withdrawal of insulin in insulin-dependent diabetics suggests a potential therapeutic use of this agent in diabetes. Presently, however, its short half-life and diverse actions preclude such use and have prompted the search for more specific and longer-acting analogs.
