The onset of melatonin secretion under dim light conditions (DLMO) and the circadian temperature rhythm during a constant routine were assessed in 6 female controls and 6 female patients with winter depression (seasonal affective disorder, SAD) before and after bright light treatment. After sleep was standardized for 6 days, the subjects were sleep-deprived and at bedrest for 27 h while core temperature and evening melatonin levels were determined. The DLMO of the SAD patients was phase-delayed compared with controls (2310 vs 2138); with bright light treatment, the DLMO advanced (2310 to 2135). The minimum of the fitted rectal temperature rhythm was phase-delayed in the SAD group compared with the controls (0542 vs 0316); with bright light treatment, the minimum advanced (0542 vs 0336).
在明亮光疗前后,对6名女性对照者和6名患有冬季抑郁症(季节性情感障碍,SAD)的女性患者在暗光条件下褪黑素分泌的开始时间(DLMO)和持续日常活动期间的昼夜体温节律进行了评估。在将睡眠标准化6天后,让受试者睡眠剥夺并卧床休息27小时,同时测定核心体温和夜间褪黑素水平。与对照组相比,SAD患者的DLMO相位延迟(23:10对21:38);经过明亮光疗后,DLMO提前(23:10至21:35)。与对照组相比,SAD组拟合直肠温度节律的最低点相位延迟(05:42对03:16);经过明亮光疗后,最低点提前(05:42对03:36)。
