摘要

山蝠和黑斑蛙的乳酸脱氢酶(LDH)同工酶及血糖浓度表现出明显的季节变化。与活动期的动 物相比, 在冬眠或蛰伏期中的动物LDH_(1)缺乏、LDH_(5)明显增多(P<0.001), 血糖浓度明显升高(P<0.001)。LDH同工酶和血糖浓度的季节变化在冬眠动物和蛰伏动物 之间还存在着明显的差异。提示, LDH同工酶含量和血糖浓度的季节变化不仅与动物的能量 代谢水平相适应, 而且显示了冬眠和蛰伏两种生理过程中的可能差异。图2表3参15

Abstract

The blood sugar concentration and the lactate dehydrogenase (LDH) isozymes in serum, brain and skeletal muscle of Nyctus noctula during hibernation and of Rana Nigromaculata during dormancy and activity period period were compared by using method of polyacrylanide gel electrophoresis. Both LDH isozymes and blood glucose concentration showed obvious seasonal changes. In contrast to animals during activity period, animals in hibernation and dormancy period lacked LDH_(1), while LDH_(5) and blood glucose concentration increased significantly (P<0.001). Also seasonal variations of LDH isozymes and blood glucose concentration were found to be different between animal group in hibernation and animal group in dormancy. The above results indicated that seasonal changes of LDH isozymes and blood glucose concentration not only adapted to the level of energy metablism but also showed difference between physiological statusduring hibernation and during dormancy.
