摘要
观察了６只刺猬，在人工低温冬眠过程中体温、心率和呼吸频率的变化及缺氧的影响。在０～４℃单纯低温环境中，刺猬经２１～３４ｈ入眠。在冬眠状态下体温由对照的３３．９±０．５℃降低至６．６±３．２℃；心率由对照的２３３．０±２５．４次／ｍｉｎ减少到３８．５±２５．５次／ｍｉｎ；呼吸频率由３３．４±６．１次／ｍｉｎ减少到２６．２±１７．１次／ｍｉｎ。在低温缺氧条件下体温、心率初期大幅度降低，经５１～６６ｈ刺激入冬眠。实验结果表明，单纯低温冬眠和低温缺氧复合作用下冬眠刺猬的体温、心率等生理变化有差别；缺氧使刺猬进入冬眠时间延长，使冬眠状态变浅。
Changes of body temperature(Tb) , heart rate(HR) and respiratory frequency(RF) were observed
in 6 hedgehogs during hibernation and the hypoxic hybr-nation under 0～4℃, the hedgehogs
entered winter sleep in 21～34 hours。 Average Tb was 6±3.2℃’,HR 38.5±25. 5b/min and
RF 26.2±17. 1b/min in the state of hibernation。 Under conditions of low temperature and
hypoxia , the curves of Tb , HR and RF moved leftward and the time of entering winter-sleep
state was delayed to 51～66 hours, The degree of hibernation became slighter : Tb , HR and
RF were l 2.3±4.8℃,77.0±35.7b/min or 48.5±22. 6b/min respectively。
