On the basis of our own experimental data and those from the literature, the reproducibility of day-night variations in physiological functions--their 'circadian pattern'--is examined in five sections. They concern the problem of intra- and interindividual variability, demonstrated by the rhythm of deep body temperature, the dependence of the pattern on experimental conditions, and as further examples circadian rhythms in the endocrine system, in blood constituents, in blood pressure and in psychomotor performance. The survey is considered to contribute to the question of how important the circadian temporal structure may be in the search for reference values and hence in diagnosis.

1. The aim of the present study was to investigate the effects of a short (1 day) fast by testing biohumoral variables associated with the human circadian rhythm. 2. Fifteen clinically healthy male volunteers (32 +/- 8 years old) participated in the study. Subjects were fed a control diet for 7 days. The last day was a control day and the following 8th day was the fasting day. Each subject was asked to collect urine seven times over a 24 h period. Chemical and hormonal variables were measured in each fractionated urine specimen. The time- qualified urinary excretion rates were biometrically analysed using conventional and chronobiological methods. 3. During fasting, significant incremental changes were detected in the urinary excretion rates of potassium, aldosterone, 17-hydroxycorticosteroids and adrenaline and significant decremental changes were detected in the excretion rates of sodium, chloride, creatinine, urea nitrogen, uric acid, 17-ketosteroids, noradrenaline and dopamine. The circadian rhythmicity of the variables was well preserved and remained almost stable throughout the fasting phase. 4. Fasting affected the mean oscillatory levels and oscillatory amplitudes of variables, suggesting that nutrients may have played roles as tonic and phasic modulators on the mechanisms that physiologically regulate ircadian rhythmicity.
