[THE MODIFICATION OF THE METHOD OF NATURAL PERIODIZATION OF BIOLOGICAL PROCESSES].

A new variant of the method of natural periodization of biological processes is proposed. In contrast to the original variant, in which each parameter is coordinated with respect to its average value during all the period of observation, in the proposed modification the parameters are coordinated with respect to their control values, that seems to be more logical in the experimental studies. Both variants were applied for the evaluation of twomonth-long dynamics of 19 morphological parameters of the part of an adrenal medulla surviving after laser damage. Three natural periods of were identified of the remodelling of the organ structure and their functional interpretation is given. It is shown that the original variant more clearly highlights the important nodal points, while the proposed modification more accurately reflects the general nature of the changes. Thus, both the variants are complementary and their combined use improves the efficiency of the method for experimental studies.
