It is a pleasure to welcome the three authorities who will carry the major load of presentations in our symposium today. They are Dr. Frans Jöbsis of Duke University School of Medicine, Dr. Eugene Robin of The University of Pittsburgh School of Medicine, and Dr. Norman Carter of The University of Texas Southwestern Medical School. We are also grateful for the presence of Dr. Lutz Kiesow of the Naval Medical Research Institute, Bethesda, Maryland. Dr. Kiesow will assist in the discussions to be held after each major presentation. Each of these men is an international authority in his field, and we are more than fortunate to have this group with us today
