The British Society of Gastroenterology

The spring meeting was held at the University of Southampton on 10 to 12 April 1975. On the first morning scientific papers were read at a meeting of the Liver Club and the Council of the British Society of Gastro- enterology met in the afternoon. On Friday morning a symposium on 'Immunology of liver disease' was held jointly with the Liver Club with Professor Ralph Wright in the Chair, and there was a meeting of the Path- ologists' Group in the afternoon. The spring meeting banquet was held at Beaulieu Abbey on Friday evening. Also on Friday afternoon and on Saturday morning there were sessions devoted to scientific papers on 'Coeliac syndromes' (Chairman: Dr M. H. Sleisenger), 'Biliary diseases' (Chairman: Dr K. W. Heaton), 'Stomach' (Chairmen: Dr G. Milton-Thompson and Dr D. Colin-Jones), 'Intestinal transport-polypeptides' (Chairman: Professor C. C. Booth), 'Liver' (Chairmen: Professor Sheila Sherlock and Professor A. E. Read), 'Inflammatory syndromes' (Chairman: Dr S. C. Truelove), 'Oesophagus, stomach' (Chairman: Dr J. Bamforth), 'Pancreas' (Chairman: Mr J. E. Trapnell), 'Stomach hormones' (Chairman: Professor Ian McColl), and 'Colon' (Chairman: Professor J. C. Goligher). Abstracts ofthese papers follow.
