[Myocardial ultrastructure in fetal rabbits following mechanical trauma].
An area of the myocardium of 23-day-old rabbit fetuses after mechanical tramua was studied electron-microscopically. Six days after trauma in the focus of lesion myocardial cells were found the general submicroscopic organization of which was identical to the ultrastructure of myocardium cells of intact animals and muscle cells of other parts of the left ventricle of the heart of experimental animals. Besides, in the former focus of lesion of the myocardium tissue electron microscopy revealed younger myocardial cells than those in the myocardium of the intact animals as well as cells showing early stages of differentiation. The results indicate that at the site of the lost myocardial tissue in 23-day-old rabbit fetuses 6 days after trauma there appears an intact cross-striated musculature of the heart.
