Falk Symposium No. 82, held in Halle, Germany, November 1994, focuses on the advances made in understanding the aetiology and pathogenesis of inflammatory bowel disease (IBD). Sections of this book, the Proceedings of the conference, are devoted to extraintestinal manifestations, cancer development, IBD in the context of pregnancy, and the assessment of disease activity, prognosis and quality of life. The second half of the book is devoted to the discussion of standards and new developments in diagnosis, conservative management and surgery. Audience: All clinicians and basic scientists working in the field of IBD.

Although cell turnover in normal adult liver is extremely low, hepatic tissue is notorious for its almost infinite capacity to regenerate in cases of viral, toxic or traumatic damage. Hepatocellular carcinoma is one of the most frequent malignancies worldwide and causes more than a million deaths per year. The mechanisms governing normal proliferation and malignant transformation of liver cells are of utmost interest for the understanding of regeneration and hepatocarcinogenesis and for the development of new therapeutic strategies. Therefore, the International Falk Workshop held in Halle, Germany, on January 29-30 1998, focused on the issues of normal and malignant liver cell growth. Knowledge in this area of research has expanded rapidly during recent years. This book of proceedings summarizes the latest advances both in basic science and clinical research. Stimulating discussion set the basis for the development of new strategies in diagnosis and treatment of hepatocellular carcinoma and for the manipulation of regeneration in cases of acute or chronic loss of functional liver tissue.
