摘要：Diurnal variations of 17-ketogenic steroid, catecholamine, sodium, potassium, calcium and inorganic phosphate excretion in three-shift workers were investigated to obtain the information on the adaptability to night work, with special regard to age-difference. Catecholamine excretion rhythms, particularly adrenaline rhythm, which generally show the peak in daytime in ordinary non-shift work, were demonstrated to be adapted rapidly to night work, though not to a large extent, by the finding that the peak of excretory rhythm corresponded to the physical andmental activities in the night shift.The diurnal rhythm of 17-ketogenic steroids appeared to be flattened only on the fifth day of the night work in the middle-aged workers and the second highest peak of the rhythm was observed in the evening of the night shift day in the adolescents. Potassium rhythm was dissociated from the other electrolyte ones which were maintained in the normal rhythms evenin the night shift. The age-difference of adaptability to night work is discussed from the diurnal rhythms of 17-ketogenic steroid and adrenaline excretion.
