In the hibernating ground squirrel activity of adrenal dopamine-beta-hydroxylase was significantly lower as compared with the active animals (P less than 0.01). The highest activity of this enzyme was found in animals tested immediately after arousal from hibernation (P less than 0.01). The adrenal weight was higher in hibernating animals than in the active or aroused ones. The difference between the active and aroused animals was significant (P less than 0.01). Extremely high enzyme activity was found in the adrenals of animals exposed to continuous light for 3 weeks as compared with active animals kept in continuous darkness or with controls subjected to a regime of 12 hr light - 12 hr darkness (P less than 0.01). The weight of the adrenals in the three groups was about the same level.
与活跃的地松鼠相比，冬眠地松鼠肾上腺多巴胺-β-羟化酶的活性显著降低（P<0.01）。该酶活性最高的是刚从冬眠中苏醒后接受测试的动物（P<0.01）。冬眠动物的肾上腺重量高于活跃或苏醒后的动物。活跃动物和苏醒动物之间的差异显著（P<0.01）。与处于持续黑暗中的活跃动物或接受12小时光照-12小时黑暗周期的对照组相比，连续光照3周的动物肾上腺中发现了极高的酶活性（P<0.01）。三组动物的肾上腺重量处于大致相同的水平。
