[Space-time organization of cellular systems in the normal and pathologic states].

The time-space organization of biological systems, cell systems in particular, is one of the most important problems of current theoretical biology having medical implications. The presented view of the general structure of the temporal organization of biosystems and their development in the course of life evolution interprets the temporal organization of a living system as a complex of regular changes in time, the biological rhythms included, its structures and functions which are interactive and show relationships with cyclic alterations of environmental conditions. A special organization is composed of a group of different structures and related functions which are arranged according to a certain pattern in the space occupied by the biological system and interact with each other. The experimental evidence obtained in studies of the proliferative and metabolic systems of the liver, testify to the existence of a general time-space organization in the cell systems. This organization represents an entity formed by the cellular temporal and special organizations and maintained by relationships and interactions between them.
