Physiological role for cholecystokinin in reducing postprandial hyperglycemia in humans.
It is known that the ingestion of glucose alone causes a greater increase in plasma glucose levels than ingestion of the same amount of glucose given with other nutrients. Since physiological plasma concentrations of cholecystokinin (CCK) prolong gastric emptying, it is proposed that after a meal, CCK may modify plasma glucose levels by delaying glucose delivery to the duodenum. To evaluate the...
متن کاملRole of hyperglycemia in nitrotyrosine postprandial generation.
OBJECTIVE Recently, much attention has been paid to the possibility that postprandial hyperglycemia may be a cardiovascular risk factor in diabetes. Oxidative stress has been involved in the pathogenesis of diabetic complications, and increased plasma levels of nitrotyrosine, a product of peroxynitrite action, have been found in the plasma of diabetic subjects. The aim of the present study was ...
متن کاملSatiety effects of a physiological dose of cholecystokinin in humans.
Cholecystokinin 33 (CCK) was infused intravenously to eight healthy obese women and 10 healthy lean women of the same age, in doses that elicited plasma cholecystokinin concentrations in the physiological range. The effect of these infusions after a standardised banana 'shake' (preload) on food intake and satiety signals was compared with the effect of saline infusions in the same subjects. For...

متن کاملEndogenous cholecystokinin in postprandial lower esophageal sphincter function and fundic tone in humans.
Transient lower esophageal sphincter (LES) relaxations (TLESRs) are the main underlying mechanism of gastroesophageal reflux. Although CCK acts through CCK-A receptors to increase the TLESRs induced by gastric distension, the respective roles of endogenous CCK and fundic tone in triggering postprandial TLESRs remain unknown. The aim of this study was to determine the effect of the CCK-A recepto...
