Foreword The Sixth Workshop on Vitamin D was held in the Centro Congressi of Merano, Italy, which is located in the northern Tyrol region of that country. The meeting was held from March 17-22,1985. In attendance were 474 registered delegates from 27 countries. These include representatives from Algeria (2), Argentina (1), Australia (14), Austria (5), Belgium (12), Canada (15), Denmark (20), Federal Republic ofGermany (24), Finland (6), France (37), German Democratic Republic (17, India (1), Israel (17), Italy (33), Japan (36), Norway (9), Poland (4), Saudi Arabia (2), South Afrika (2), Spain (7), Sweden (13), Switzerland (13), The Netherlands (25), Turkey (3), United Kingdom (36), United States (133) and Yugoslavia (2). Interest and attendance at Vitamin D Workshops still continues to grow. Tabulated below are the dates and attendance as well as number oftalks given at the six Vitamin D Workshops that have now been held. Since the time of the Fifth Workshop held in Williamsburg, Virginia in February of1982, there has been a clear increase in attendance at the Workshop as well as in the number of submitted presentations. This reflects the continuing growth in research frontiers related to the vitamin D endocrine system.

The formal program of the Sixth Workshop on Vitamin D included 48 verbal presentations by invited speakers and 29 promoted free communications as well as 380 poster presentations. This program was conceived and put together by the Program Committee of the Sixth Workshop; members of this committee included R. Bouillon (Belgium), A. Caniggia (Italy), J. W Coburn (USA), H. F DeLuca (USA), S. Edelstein (Israel), J. A. Eisman (Australia), M. R. Haussler (USA), M. F Holick
VI (USA), J. A. Kanis (United Kingdom), D. E. M. Lawson (United Kingdom), A. W Norman (USA), J. L. H. O'Riordan (United Kingdom), W H. Okamura (USA), B. L. Riggs (USA), T. Suda (Japan), M. Thomasset (France), M. Uskokovic (USA), R. H. Wasserman (USA). A major responsibility ofthe Program Committee was to review the 409 abstracts submitted as Free Communications and to individually „score" each abstract; from this group, 29 abstracts were selected by the Program Committee for inclusion on the verbal program ofthe meeting. In addition a special feature of the Sixth Workshop was a new component of the program entitled, „Late Breaking Events." A sub-committee of the Program Committee evaluated abstracts which were turned in at the time of the meeting in Merano; these presentations were to cover laboratory developments which occurred since the time of submission of abstracts in October 1984 and the occurrence of the meeting in March 1985. A total of 8 abstracts were received and 6 were programmed on the last day of the meeting as 7-minute presentations; the chapters for each of these „Late Breaking Events" are included in this volume. Presented in this volume are papers prepared by the invited speakers as well as submitters ofmany ofthe Free Communications. The chapters in this book are grouped according to their general subject matter based on the classification made by the submitting authors, e. g. vitamin D chemistry, vitamin D metabolism and catabolism, receptors for l,25(OH)2D3, renal osteodystrophy, osteoporosis, etc. Due to the large number of Free Communications (380) a major effort was made to allow adequate time for presentation and discussion of the many significant results that were presented by this mechanism. There were seven Poster Sessions scheduled throughout the meeting; during a 2-3 hour time interval the posters were „manned" by the submitting authors. Importantly, however, each poster was available for review for a minimum of 10-11 hours each day. Thus on each day approximately 100 posters were continuously presented throughout the day. The highlights of the Sixth Workshop on Vitamin D were again amazing in terms of ther variety; undoubtedly this reflects the diverse interests of the chemists, biochemists, physiologists and clinicians who attended the meeting and who are actively conducting research in the various aspects of the vitamin D endocrine system. Clinical highlights included presentation of results of ongoing trials of l,25(OH) 2 D 3 in the treatment of post-menopausal osteoporosis. There was uniformity of agreement in the four osteoporosis presentations that under appropriate circumstances l,25(OH)2D3 may make an important contribution to available treatment modalities. Also there was continuing status reports on the effectiveness of 1,25(0 H) 2 D 3 in treatment of renal osteodystrophy. Several presentations focused on the application of l,25(OH)2D3 in the early onset of renal failure; again the utility of l,25(OH)2D3 was supported by the presentations given at the Workshop.
VII Several significant advances were also reported in terms of our basic understanding of the vitamin D endocrine system. Notable in this regard was the presentation ofthe molecular biological cloning of the mRNA for the D-binding protein; this resulted in the generation of the primary amino acid sequence for both the rat as well as human DBP This important D-transport protein is apparently related to the protein families of albumin and a-feto protein. Also the amino acid sequence was reported, as derived from classical sequencing techniques, of the principle intestinal vitamin D induced 28,000 dalton calcium binding protein. An intriguing chemical observation was the sythesis of an analog of l,25(OH) 2 D 3 , namely l,25S,26(OH) 3 -A22-D 3 which was highly active in mediating cell differentiation but had a diminished activity in terms of its hypercalcemic actions as compared to the parent l,25(OH) 2 D 3 . Clear and incisive evidence was presented that l,25(OH) 2 D 3 could be produced at various extra-renal sites; in this regard it was intriguing to learn that y-interferon could stimulate the production of l,25(OH) 2 D 3 by pulmonary macrophages. Certainly the area of the program which attracted the largest submission of Free Communications was that relating to l,25(OH) 2 D 3 receptors and their participation in cell differentiation. It is clear from these collective results that a micro/paracrine endocrine system exists for l,25(OH) 2 D 3 in terms ofmediating appropriate stem cell differentiation. The Advisory Committee and the Program Committee would like to acknowledge the financial support of American Bio-Science Laboratories, Amersham International, Chugai Pharmaceutical Co. Ltd., Du Pont NEN Products Division, E. Merck, Fondazione Hoechst, Gambro Dialysatoren, Hoffmann-La Roche and Co. Ltd. (Basle), Hoffmann-La Roche (Nutley), Immuno Nuclear, Leo Pharmaceutical Products, Mead Johnson Nutritional Division, Nuclear Data, Inc., Roche S. P A., Roussel Maestretti, Teijin Limited, and The Procter and Gamble Company. Without this generous governmental and multi-corporate financial support it would have been impossible to have a Vitamin D Workshop which included such a comprehensive program and world-wide attendance. A special tribute is also due to the tireless efforts of the Workshop Conference Secretaries. Ms. Lean S. Gill and her colleagues in Riverside, Ms. June E. Bishop and Ms. Ann Hall were responsible for the bulk of the secretarial activities related to production of the abstract book and the advanced registration process. In addition Workshop Secretary, Ms. Pam Moore effectively and professionally handled the multitude of details concerned with the actual conduct of the meeting in Merano; in this capacity she was ably assisted by both Ms. June Bishop and Ms. Tieneka Hansson.
