BLOOD GLUCOSE AND SERUM INSULIN LEVELS IN CHILDREN WITH CYSTIC FIBROSIS

The results of glucose and insulin levels after oral glucose and intravenous glucose, glucagon, and tolbutamide in 61 children with cystic fibrosis are presented. The results suggest that the increased incidence of impaired glucose tolerance found in them is due to a defect in the release of a glucagon-like substance from the alimentary system, in addition to defective islet cell function.
