我们调查了一次 11 小时向东飞行中褪黑激素节律的重新夹带情况。八名男性受试者参与了本研究。飞行前进行了一次血液采样，飞行后进行了两次血液采样。白天，除了采血外，受试者都暴露在户外的自然时间中。八名受试者中的七名表现出逆向再夹带，另一名受试者表现出顺向再夹带。纽约自然日光强度达 20 000 勒克斯。至于纽约的再夹带方向，逆向再夹带自然占主导地位。
We investigated the re‐entrainment of melatonin rhythm in an 11‐h eastward‐bound flight. Eight male subjects participated in the present study. Blood sampling was carried out once before the flight and twice after the flight. During the daytime the subjects were exposed to natural zeitgeber outdoors on the day except the blood sampling. Seven of eight subjects showed antidromic re‐entrainment, and the other subject showed orthodromic re‐entrainment. The intensity of natural day light in New York amounted to 20 000 lx. As for the direction of the re‐entrainment in New York the antidromic re‐entrainment is naturally dominant.
