摘　　要：本文分析了大蟾蜍冬眠前、冬眠期和冬眠后三个不同时期血清皮质醇、血清Ｔ４和血清Ｔ３含量的变化并与同期血糖水平和肝糖元含量进行比较，结果表明：血清皮质醇在冬眠期呈显著下降趋势，冬眠后又明显回升，血糖浓度的变化也表现出这种趋势；血清Ｔ４在冬眠期呈明显上升的趋势，冬眠后又降回到冬眠前的水平上；血清Ｔ３一直保持上升趋势；肝糖元含量则一直保持大幅度下降的趋势。此外，本文还对上述变化的生理学意义进行了讨论。This study analyzed the variations of the serum cortisol,thyroxine(T4)and triiodothyronine(T3) in Bufo gargarizans during pre-hibernation,hibernation and post-hibernation.The variations of the serum hormones were compared with the change of glucose metabolish during those three periods.The results show that the serum cortisol and serum glucose tend to decline significantly during hibernation and increase markedly during posthibernation.The serum T4 tends to increase during hibernation markedly and decline to the same level of pre-hibernation at the end of post-hibernation.The serum T3 always tends to increase during those three periods and The hepatic glycogen always tends to decline during those three periods.The signification of the variations of the serum hormones is also discussed in this paper.
