Popis: THE study of the permeability of mitochondria, to which the sarcosomes of cardiac muscle are closely related, has depended on indirect, mostly biochemical, methods1,2. One of the difficulties in any other approach has been the relatively great (and obviously abnormal) permeability of isolated mitochondria or sarcosomes to most ions at room temperature, which results in swelling and other morphological changes. With the discovery that Ca++ ions are intimately related to this abnormal permeability of sarcosomes and that the calcium-chelating agent versene, by removing calcium from the granules, greatly increases, their stability at room temperature3, the problem of sarcosome permeability has become more accessible to attack by other methods.
