Studies on carbohydrates in reptiles

Summary Sugar tolerance tests were performed on Uromastyx at different temperatures ranging from 15–47° C. Temperature has an effect on the height of sugar tolerance curves, on the time needed for reaching maximum hyperglycemia, and on the rate of disposal of excess glucose from the blood stream.The magnitude of the rise of blood glucose is proportional to the dose of glucose given to the animal. The maximum glucose in blood is reached after a constant time, regardless of the amount of glucose added.In hepatomised animals, the reaction towards injected glucose is of a short duration. Further the extrahepatic tissue shares in the removal of excess glucose from the blood.In depancreatised animals sugar tolerance curves are of diabetic type.
