Abstract: 
Na+-K+ ATPase was demonstrated in excretory organs of S. officinalis using a cytochemical procedure. In the renal appendages, both epithelia of the pancreatic appendages, the folded epithelium of the branchial heart appendage and the transport-active epithelium of the gill, the enzyme is localized exclusively in the basolateral cell membranes, i.e., the membranes of the basal labyrinth and the lateral plasma membranes. Na+-K+-ATPase also is located in the sarcolemma of the muscle fibers of the branchial heart. Distribution and localization of the enzyme is further substantiated by [3H]-ouabain autoradiography. The possible involvement of Na+-K+-ATPase in the excretion of ammonia and in ionic regulation in dibranchiate cephalopods is discussed.
