Circadian rhythm in blood glucose levels in normal and hepatectomized mice

Abstract A circadian rhythm in blood glucose of normal, intact, standardized male mice is reported. Significant fluctuations of blood glucose during the first and second 24‐hr periods after hepatectomy, were observed. These fluctuations were not synchro‐nized with the normal rhythm and take place around overall 24‐hr average which is much lower than the one observed in normal mice. The phase relationships between the described variations in blood glucose and the animal's feeding patterns are discussed.
