This volume comprises a series of original articles, updates and reviews on relevant topics in hepatology which were presented at a meeting in Freiburg im Breisgau to honour the 60th anniversary of Dr. Herbert Falk. Since 1967, Dr. Falk and the Falk Foundation have generously sponsored more than 40 congresses and symposia on liver diseases, held mostly in Freiburg, The Black Forest or in Basel, which have become milestones in the ex change of scientific information in hepatology (see ''To Herbert Falk on his Sixtieth Birthday'' in this volume). Many of these congresses and symposia have been published in the ''Falk Symposia'' series by MTP Press. We asked hepatologists who took part in former Falk liver meetings to contribute to a one day symposium to celebrate Dr. Falk''s anniversary. We were greatly gladdened by the spontaneous and unrestrained acceptance that we received from all sides. We wish to express our deep appreciation to all the speakers and moderators who travelled, at their own expense, from all parts of the world to Freiburg and who with their presentations, made the meeting a stimulating and refreshing event. The editors'' thanks are also addressed to Mr. D. G. T. Bloomer and Mr. P. M. Lister from MTP Press for their valuable cooperation in preparing this volume for publication. This book testifies to the worldwide appreciation and gratitude held for Dr. Falk by the community of hepatologists. The Editors ix List of Contributors P. BACK K. F. A.
