Официальное название
Investigating the Effect of Glucagon on Cognitive Function and Cerebral Glucose Metabolism in Humans: A Pilot Study
Обзор
In this study the investigators will investigate the acute effects of increasing alanine exposure on metabolic parameters in healthy participants. Participants will participate in one study day. After initial baseline blood samples, a three-hour intravenous infusion with glucagon will be initiated. The infusion rate will be increased every 30 minutes.
Подробное описание
Two peripheral catheters will be placed in the antecubital vein of each arm for infusion of L-alanine and blood sampling respectively. The infusion rate of alanine will start at 1.4 μmol/kg/min and increase every 30 minutes over a 3-hour period, up to a maximum of 28 μmol/kg/min. The study day will last approximately 4 hours, and a maximal blood volume of 130 ml will be collected. Blood samples for the analysis of plasma glucagon, glucose, insulin, C-peptide etc. will be drawn every 15 minutes.
