Ethyl alcohol which has been reported to be without effect on insulin secretion apparently modifies beta-cell function nevertheless, as indicated by the plasma insulin responses to glucose loading after prior administration of alcohol. Glucose was injected intravenously in nine young adults on three separate occasions at intervals of at least two weeks. During the twelve hours preceding each test the subjects received ethanol either by mouth or by vein or, as a control, no ethanol. Plasma… Expand

Differential Plasma Insulin Response to Glucose and Glucagon Stimulation Following Ethanol Priming
TLDR
An unexpected finding was the inhibitory effect of alcohol on glucagon-induced insulin release, in direct contrast to its effect when glucose is the insulinogogue, suggesting that glucose and glucagon exert their effects throughdifferent mechanisms or on different fractions of the insulin pool. Expand
Ethanol-induced Alterations of Glucose Tolerance, Postglucose Hypoglycemia, and Insulin Secretion in Normal, Obese, and Diabetic Subjects
TLDR
In insulin-deficient diabetic patients the absent early insulin response could not be restored by ethanol, and the late component of insulin release was little increased by alcohol infusion, while ethanol did not improve the glucose utilization of diabetic patients. Expand
Effects of ethanol ingestion on glucose tolerance and insulin secretion in normal and diabetic subjects.
TLDR
In mild diabetic patients, moderate intake of ethanol is without acute deleterious effects on carbohydrate homeostasis and may in some instances improve the blood glucose response to ingested carbohydrate. Expand
Effect of Ethanol on Stimulus-induced Insulin Secretion and Glucose Tolerance: A Study of Mechanisms
TLDR
It is proposed that (1) ethanol in vivo acutely induces hypocalcamie, which inhibits glucose- and tol butamide-induced insulin secretion—which, in turn, causes glucose intolerance and prevents tolbutamide- induced hypoglycamie. Expand
Effect of Ethanol on the Glucose-mediated Insulin Release in Triply Catheterized Anesthetized Pigs
TLDR
Ethanol seems to potentiate, in an inverse concentration-dependent manner, the glucose-mediated insulin response through an action directly on the pancreas through the action of ethanol in the preinfusion period. Expand
Glucose- and Tolbutamide-Mediated Insulin Response after Preinfusion with Ethanol
TLDR
Intravenous glucose tolerance tests (1VGTT) were carried out in five normal subjects after ethanol preinfusion for one, two or four hours and the subsequent insulin response followed the same pattern as seen in the four-hour-IVGTT experiment. Expand
Some Aspects of “Acute Phase” Insulin Release in Healthy Subjects
TLDR
It is suggested that studies involving the effects of agents on the dynamics of acute phase insulin response to glucose be done with glucose doses which produce submaximal β-cell stimulation. Expand
Ethanol-insulin interrelationships in the rat studied in vitro and in vivo: evidence for direct ethanol inhibition of biphasic glucose-induced insulin secretion.
TLDR
The data suggest that stimulus-induced insulin secretion may be enhanced by an ETOH metabolite if the ETOh exposure is prolonged and at a low level, and indicates that second phase secretion of insulin from the pancreas is more sensitive to the acute effects of ETO H. Expand
Effect of Ethanol, Acetaldehyde, and Acetate on Insulin and Glucagon Secretion in the Perfused Rat Pancreas
TLDR
The block of insulin secretion and the increased secretion of glucagon could explain the diabetogenic effect of ethanol demonstrated in vivo and the mechanism by which ethanol acts on the pancreatic β- and α-cells is discussed. Expand
Changes in plasma insulin during ethanol-induced hypoglycemia.
TLDR
An ethanol infusion is useful in excluding a suspected insulinoma, and may be useful in establishing the diagnosis in patients in whom the diagnosis is in doubt. Expand

Effect of Ethanol on Plasma Glucose and Insulin in the Fasted Dog.∗
TLDR
Plasma alcohol levels of 143 to 286 mg % were achieved by intravenous infusion of ethanol into 9 dogs which had been deprived of food for varying periods, a suggestion which is reinforced by the recent demonstration that such dogs exhibit an altered response to exogenous insulin. Expand
Effect of Selected Hexoses, of Epinephrine and of Glucagon on Insulin Secretion in Man
TLDR
Findings agree with in vitro evidence that epinephrine directly inhibits pancreatic secretion of insulin and suggest that this may be a direct effect of glucagon on the release of insulin by the pancreatic beta cell. Expand
Stimulation of insulin release by glucagon in noninsulin-dependent diabetics.
TLDR
A significant rise in IRI occurred in both the normal and diabetic subjects, which would imply a different mechanism for the activation of insulin secretion for glucagon as opposed to glucose, and suggests the possibility of a physiologic effect on insulin release by the α cells on the β cells of the islets of Langerhans.

Ethanol-induced Hypoglycemia: II. Mechanism of Suppression of Hepatic Gluconeogenesis
TLDR
Data are consonant with the thesis that the increased NADH2/NAD ratio, which characterizes ethanol oxidation by the liver cell, causes a partial block at several points in the gluconeo genic pathway and is responsible for the ethanol-induced suppression of hepatic gluconeogenesis. Expand
Exhaustion of Insulogenic Reserve in Maturity-onset Diabetic Patients During Prolonged and Continuous Hyperglycemic Stress
TLDR
The data indicate that unremitting hyperglycemia tends to exhaust insulogenic reserve in adult-onset diabetics, and that betacytotropic collapse occurs most rapidly in patients with severest clinical intolerance to carbohydrate. Expand
ALCOHOL HYPOGLYCEMIA. II. A POSTULATED MECHANISM OF ACTION BASED ON EXPERIMENTS WITH RAT LIVER SLICES.
TLDR
Under conditions of limited pyruvate turnover and availability, ethanol inhibited the formation of glucose-14C and increased lactic acid- 14C, although the consumption of oxygen was reduced only minimally. Expand

Beta-cytotrophic effects of glucose, glucagon, and tolbutamide in man.
TLDR
Rapid increases in plasma-levels of immunoreactive insulin were observed after intravenous injection of glucagon or tolbutamide, and Pretreatment with oral carbohydrate notably enhanced the response to either alone or both combined. Expand
