This symposium on cerebral and coronary vascular disorders and infarcts is probably the first attempt to hold a joint discussion in this field. Despite many difficulties we feel that it has been successful and we hope that it will stimulate further interest and investigations. To hold such a meeting with scientists from far away was possible only with the assistance of Bundesminister fUr Jugend, Familie und Gesundheit, Minister fUr Hissenschaft und Forschung des Lan- des Nordrhein-Westfalen, Max-Planck-Gesellschaft zur Forderung der Wissenschaften e.V., Deutsche Forschungsgemeinschaft, to whom we are very grateful. Moreover the pharmaceutical industry gave assistance in the organization and the transcript of the pro- ceedings. Dr. G~TZE of Springer-Verlag, was, as we will explain later, the original promotor of the idea for such a meeting. We should like to thank Springer-verlag for the excellent layout and quality of this book. Koln, Spring 1977 K.J. ZULCH, W. KAUFMANN K.-A. HOSSMANN, V. HOSSMANN Contents Welcome K.J.

The first international symposium on brain edema was held in Vienna/ Austria in 1965 followed by altogether eight meetings since. The most recent was organized in Y okohama by the Department of Neurosurgery of the Musashino Red Cross Hospital, Tokyo. The continuing interest of both, clinicians and experimental scientists alike may be attributable to the fact that brain edema is a common denominator of many cerebral disorders, which under acute conditions threatens life and weIl-being of afflicted patients. Although progress in understanding as weIl as treatment can be recognized since 1965 many problems remain, particularly concerning the control of brain edema under acute conditions, as in trauma or ischemia. A quantum leap was the distinction of the cytotoxic and vasogenic brain edema prototypes as advanced by Igor Klatzo, providing for transition from a morphological to functional understanding now. The recent brain edema meetings were certainly benefiting from developments of both, molecular neurobiology on the one hand side and functional brain imaging at an ever-increasing resolution on the other, such as magnetic resonance imaging orpositron emission tomography. The international symposium in San Diego 1996 may witness further breakthroughs, hopefully also of effective treatment modalities. The symposium in Y okohama was dedicated to the "Legacy of 28 Years of Brain Edema Research" as a reminder of accomplishments as weIl as remaining challenges.
