刺猬冬眠的人工改变——Ⅱ.在冬眠季节用高温防止冬眠的出现
ARTIFICIAL MODIFICATION OF HIBERNATION IN THE HEDGEHOG.Ⅱ. PREVENTION OF HIBERNATION BY HIGH TEMPERATURE IN THE HIBERNATING SEASON.
【摘要】 <正> 冬眠的哺乳动物在冬眠季节是否可以不必冬眠,关於这个问题并没有详细的研究。在科学文献中有些记载提到实验室内的冬眠动物可以在各季维持活泼状态而不冬眠,但是并没有提供能令人信服的实验记录,没有根据可靠的冬眠标志进行严格的检查。因此,此类报告的可靠性实属可疑。
【Abstract】 Experiments on prevention of hibernation were performad with two series of hedgehogs in the hibernating seasons (October to March or April) of 1949-1930 and 1930-1951 by maintaining the laboratory temperature at summer level,averaging about 27℃.Under such circumstances hibernation,when it did occur,was not deep and symptoms of hibernation were not well-marked.The only reliable indication of hibernation was a decrease in body.temperature;any value of rectal temperature below 32.5℃ was considered as a sign of hibernation.Experimental results showed that in some hedgehogs high temperature could prevent hibernation completely.Among a total of 38 hedgehogs 8 (21%) showed no indication of hibernation whatsoever,and the number of hibernating days hi the remaining hedgehogs was greatly reduced to not more than 1/6 of the entire duration of the experimental period.The prevention of hibernation in the hibernating season was harmless to the existence,growth and development of some hedgehogs,yet in others it seemed to be a difficult task that might lead to death of the animals.It was suggested that such differences in the readiness of prevrntion of hibernation might be related to the health conditions and the types of nervous system of the hedgehogs.
