A STUDY OF IMMUNOHISTOCHEMISTRY OF ATRIOPEPTINS IN RAT HEART / 解剖学报

ABSTRACT

The distribution of atriopeptins in the rat's heart was studied with immunohis-tochemical method. It was noticed that the immuno-reactive granules existed in most atriaI muscle cells. It was abundant in the cytoplasm about the paranuclear position. The cardiocytes of both atrial appendages gave an intense immuno-reaetion. Most cardiocytes of right atrium were more reactive than those of left atrium. Parts of atrial muscle cells which were distributed in the back of the left atrium, atrial septum and coronary sinus were negative in reaction.
