The rhythm of circadian variations of plasma insulin level was similar in 48 h fasted and in fed rabbits; however, the amplitude of variations was less important in fasted animals. Plasma glucose level did not change during circadian cycle. In conclusion, we showed in rabbit a circadian rhythm of insulin with two maxima: one diurnal and the other nocturnal.
