Abstract

The rhythms of short-term arousal episodes, associated with normalization of low body temperature, were studied in hibernating Erinaceus roumanicus. The episodes of body temperature recovery during hibernation were 1.7 times more incident during the acrophase of 4.058-day rhythm of glucocorticoid hormones, detected previously, than during the batiphase of this rhythm. Ultradian rhythm of arousal episodes conformed to a 4-h biorhythm: the maximum number of body temperature resumption episodes was recorded at 00.00-01.00, 04.00-05.00, 08.00-09.00, 12.00-13.00, 16.00-17.00, and 20.00-21.00. These data indicated that in mammals the mechanisms of infradian and ultradian rhythm maintenance were stable and did not depend on body temperature or were determined by external factors with periods of 4.058 days and 4 h.

摘要

在冬眠的罗马尼亚刺猬中研究了与低体温正常化相关的短期觉醒发作的节律。在先前检测到的糖皮质激素激素4.058天节律的高峰期，冬眠期间体温恢复发作的发生率比该节律的谷期高1.7倍。觉醒发作的超日节律符合4小时生物节律：体温恢复发作的最大数量记录在00:00 - 01:00、04:00 - 05:00、08:00 - 09:00、12:00 - 13:00、16:00 - 17:00和20:00 - 21:00。这些数据表明，在哺乳动物中，次昼夜和超昼夜节律维持机制是稳定的，不依赖于体温，或者由周期为4.058天和4小时的外部因素决定。
