【Abstract】 The physiology of hibernation, of the hedgehog (Erinaceus dealbatus) has been much studied by Chao and Yeh (1950-1956). As informations on brain glycogen content in hibernating animals are scanty, the present work is undertaken.The rapid microdeter mi nation of glycogen in tissue slices developed by Van Wagtendonk, Simonsen & Hackett (1946) was adopted. The hedgehog was killed by decapitation. The fresh brain, after weighing, was dropped immediately into a formalin-ethanol (1:9) fixative. It was found that the brain glycogen content of hibernating hedgehogs (166 mg %) is more than double that of the active hedgehogs (68 mg %). When a group of hedgehogs was kept outside of the animal room in a wooden box, half-loaded with saw- dust, the animals were observed to enter or arouse from hibernation, according to the change of environmental temperature. It was found that the brain glycogen content of the hedgehog increases while hibernating and decreases while awaking. Artificially induced hibernation elicits the same kind of changes. These are in conformity with the findings of (1954) in susliks.The distribution of glycogen in. the different parts of the brain is not uniform, decreasing according to the following order: cerebellum, olfactory tubercles, neopallium, piriform lobes, olfactory bulbs. The hedgehog in hibernation has more brain glycogen than the animal in the active state, but this descenting order of distribution is still maintained.更多还原
