[Statistical approach to the validity of a diurnal cycle with periods of 4-6 hours]. / Statisticheskaia otsenka dostovernosti vnutrisutochnoi tsiklichnosti s periodami 4-6 chasov.

Confidence coefficient and reliability of previously unknown phenomenon of the interdian cyclicity (with the periods about 4-6 hs) in dynamics of physiological and pathological processes is shown. Discovery of critical time instances (at 2, 9, 14, 18, 22 o'clock of local "winter" decree time) of human life poses a problem of an application of this phenomenon to the solution of different medical and social problems.

[A problem of biological clocks. New data on the circadian rhythm of the changes in the state of the human body]. / Problema biologicheskikh chasov. Novye dannye o zakonomernostiakh sutochnogo khoda izmenenii sostoianiia organizma cheloveka.

Analysis of time-dependent development of various events in man's life (diseases, traumas traffic accidents, normal delivery, death because of diseases) and physiological processes allowed to reveal the presence of intradian cycle in their dynamics with the period about 4-6 hs. At present possible mechanism(s) of this phenomenon is being discussed.
