[The recovery process in the fetal rabbit myocardium following mechanical trauma].

Healing processes of the myocardium after an injury during the intrauterine period were studied. After the mechanical trauma of the heart the rabbit fetus is kept in the maternal organism and is born in due course. It was found that the healing of the injured part of the cardiac muscle occurred shortly and was due to the high proliferative activity of the cells. Morphological structure of the tissue appearing at the site of injury is very similar to that of the muscle tissue. However, further studies are necessary for final decision.
