Pancreatic Hormones Disappearance After Total Pancreatectomy in the Duck: Correlation Between Plasma Glucagon and Glucose

Summary

The decline of 3 plasma pancreatic hormones, glucagon (G), insulin (I) and somatostatin (S) was studied in fasting ducks after total pancreatectomy. The results show that the decrease of plasma glucose is highly correlated with the disappearance of G, while no important variation of the G/l ratio occurs during the period of observations (80 minutes) the animal being kept fasted.

No participation of pancreatic S in glucose metabolism could be detected, the origin of peripheral S in the fasting state seeming due to the intestine for about 50%.
