Arising from the Sixth Grover Conference on the Pulmonary Circulation, a NATO Advanced Research Workshop, held in Sedalia, Colorado in October 1992, this volume describes the present state of knowledge of the movement and storage of ions in vascular endothelial and smooth muscle cells. The contribut
