title: [Biological rhythm as a reflection of the unity of creation and destruction (life and death)].
abstract: The paper deals with the analysis of fundamental aspects of nature of the biological rhythm, antinomies incident to this phenomenon, its relation to the phenomena of life and death. The biological rhythm is viewed as an exemplification of the singleness of two qualitatively different states--destruction and creation, dissimilation and assimilation. Since destruction of biological structures in the course of dissimilation is irreversible by character, there is every reason to equal it with death, and to consider life the counter process of assimilative synthesis (creation) of chemical compounds directed toward revival of living substance. From this standpoint, the day phase of the circadian rhythm marked by dominance of destructive processes is a kind of death, whereas the night phase characterized by prevalence of the recovery processes signifies life. That is why the daytime status of organism differs from that at night, which is directly related to diagnostics of internal diseases: in the daytime and at night the same patient seems to be two different persons. Therefore, investigating him not only in the daytime but also at night, we could get more intimate understanding of his diseases, that is make an exhaustive diagnosis. Efficiency of night investigations combined with daytime ones has been confirmed by clinical investigations.
