[Ultrastructural characteristics of division of cardiomyocyte nuclei in adult rats].
In adult rats with experimental myocardial infarction and after swimming training load in atrial and ventricular cardiomyocytes a number of nuclei changes are revealed, which are characterized by deep strangulation with rounded borders, by fissural invagination of nuclear surface in transversal or longitudinal directions, by the presence of long intersection and micronucleus between the nuclei, by close nuclei location. The transferred pictures may be interpreted as manifestation of direct division of interphase nuclei in the absence of figures of mitotic division.
