[Rhythmic changes in morphometric parameters of fiber structure of myocardial connective scar tissue in rats].
The results of morphometrical and stereological analysis of cardiomyocytes and rats' cardiac scar conjunctive tissue are stated in this article. It was shown that during the myocardial construction, the collagen fibril tension occurs. When diastole ensues, they goes back to point of departure. The author supposes that such a rhythmical, synchronous with systole changes of scar conjunctive tissue collagen fibres indicates the conjunctive tissue scar participation in cardiac contractile activity.
