AChE activity in mouse brain stem reticular formation was studied at 4 hr intervals for 48 hr at 4 different times of the year under normal (LD 12/12) and constant light (LL) regimens. Under both illumination regimens, a significant ultradian rhythm of AChE activity was observed. In the investigated seasons of the year, changes in AChE behaviour were limited to mean activity of the enzyme (median) as well as to the amplitude and acrophase of the rhythm.
在一年中的4个不同时间，于正常（光照周期12小时明/12小时暗，LD 12/12）和持续光照（LL）条件下，每隔4小时对小鼠脑干网状结构中的乙酰胆碱酯酶（AChE）活性进行48小时的研究。在两种光照条件下，均观察到AChE活性存在显著的超日节律。在一年中所研究的季节里，AChE行为的变化仅限于该酶的平均活性（中位数）以及节律的振幅和峰相位。
