The aim of the present investigation was to ascertain circadian rhythms in adrenomedullary hormones and blood glucose level in the adult male bandicoot rat. Adrenomedullary hormones and blood glucose were measured during 0600 h, 1200 h, 1800 h and 2400 h of a 24-hour period from different groups of animals. Adrenaline, noradrenaline and blood glucose levels increased during 2400 h through 0600 h and decreased during 1200 h through 1800 h. The finding indicates that there is a circadian rhythm in adrenomedullary hormones and blood glucose level in the bandicoot rat. It is suggested that circadian fluctuation in these substances may be due to diurnal variation in the activity of the animals.
本研究的目的是确定成年雄性袋狸大鼠肾上腺髓质激素和血糖水平的昼夜节律。在24小时期间的06:00、12:00、18:00和24:00对不同组动物测量肾上腺髓质激素和血糖。肾上腺素、去甲肾上腺素和血糖水平在00:00至06:00期间升高，在12:00至18:00期间降低。这一发现表明袋狸大鼠肾上腺髓质激素和血糖水平存在昼夜节律。有人认为，这些物质的昼夜波动可能是由于动物活动的昼夜变化所致。
