Myocardial cell lesions caused by an anabolic hormone
Abstract
Early changes in the composition of heart muscle cells of the rat caused by an anabolic hormone were investigated by electron microscopy. Mitochondria and myofibrils showed changes similar to those observed in early heart failure: The mitochondria were swollen and elongated. Their matrix was sparse and the cristae were few in number. The myofibrils showed either disintegration and widened and twisted Z-bands or a complete dissolution of the sarcomeric units.
