 note = {P(論文), In the study of the effect of chilliness and the tendency of cryodomestication, the urinary output of 17-Hydroxycorticosteroids (17-OHCS) was used, and its circadian rhythm was investigated. Though urinary 17-OHCS increased during an extremely cold season, the change in relation to the cold weather has not been clarified. On the other hand, during the survey trip urinary 17-OHCS did not increase noticeably even when the test member met with an inexperienced chilliness, and it showed a rather lower level than the ordinary value. Though the tendency of cryodomestication is difficult to clarify as there are many intermediary factors, some trend of domestication could be apparently observed with respect to all the known factors including urinary 17-OHCS. The most interesting finding in this study was the circadian rhythm of urinary 17-OHCS whose pattern corresponded with the rhythm of the sun; while it showed normal pattern in the day that had clear daylight and night, in the polar rhythm of the sun circadian rhythm were disturbed. Namely, it seemed that our circadian rhythm depended on the solar rhythm, in other words, standard time of circadian rhythm was on movement of the sun.},
