[Rhythms of electrolyte excretion in healthy people].

The rhythms of urinary electrolyte excretion have been examined in normal subjects by following up every examinee for 72-120 hrs. Circadian rhythms have been detected in the predominant majority of the examinees. The mean values of other rhythm parameters (mesor, amplitude) have been established, that are suggested to be used as the reference values in the early diagnosis of abnormalities, with due consideration for the ecologic conditions and nutrition.
