The influence of different photoperiods on the secretion of melatonin and N-acetylserotonin (NAS) in the female rabbit was investigated. Under all photoperiodic conditions, 12-h light: 12-h dark (12L:12D), 2L:22D and 22L:2D, mean melatonin levels were higher during the scotophase. By contrast, mean NAS levels were 2-6-fold greater in the photophase compared to levels in the scotophase. This dissociation of circulating melatonin and NAS suggests that in the rabbit melatonin secretion is tightly controlled by the scotoperiod and NAS is probably produced by and originates from other organs as well as the pineal.
研究了不同光周期对雌性兔褪黑素和N-乙酰血清素（NAS）分泌的影响。在所有光周期条件下，即12小时光照：12小时黑暗（12L:12D）、2L:22D和22L:2D，暗期的平均褪黑素水平较高。相比之下，光期的平均NAS水平比暗期高2至6倍。循环中的褪黑素和NAS的这种分离表明，在兔中，褪黑素的分泌受暗周期严格控制，而NAS可能由松果体以及其他器官产生并源自这些器官。
