title: Degree of granulation of atrial cardiocytes: its decrease after aorto-caval fistula in the rat.
abstract: The experimental creation of an aorto-caval fistula in the rat leads to a decrease of the degree of granulation of atrial cardiocytes. This decrease is significant for granules distal to the nucleus and not for paranuclear granules. This partial degranulation reinforces the hypothesis according to which atrial cardiocytes participate in some sensitivity to local changes in blood pressure and flow.
