Abstract

The oxygen affinity of the blood of hibernating hedgehogs has been investigated previously by Clausen and Ersland (1968) and Bartels et al. (1969). The results of these studies were conflicting in so far as Bartels et al. (1969) found an increase of the O2 affinity during hibernation resulting in a P50 of 23 mm Hg at pH 7.4 37 degrees C, while Clausen and Ersland reported a P50 of 33.6 mm Hg under the same conditions, a value which was only slightly different from the one found in nonhibernating animals (Bartels et al., 1969).

摘要

先前，克劳森和埃尔斯兰（1968年）以及巴特尔等人（1969年）已对冬眠刺猬血液的氧亲和力进行了研究。这些研究结果相互矛盾，因为巴特尔等人（1969年）发现冬眠期间氧亲和力增加，在pH值7.4、37摄氏度的条件下，P50为23毫米汞柱，而克劳森和埃尔斯兰报告在相同条件下P50为33.6毫米汞柱，该值与在非冬眠动物中发现的值仅略有不同（巴特尔等人，1969年）。
