Plasma gastrin concentration and antral histology in patients with achlorhydria.

The scientific spring meeting was held at the Royal College of Physicians, London, on 10 March 1972. The morning was devoted to a symposium on 'Drug absorption and metabolism' when papers were read on 'Uptake from the intestinal lumen' (J. Nimmo), 'Mucosal transit' (D. Davis 'Kinetics of transport into blood in health and disease' (A. Brekenridge), 'Role of hepatic carrier proteins' (J. Levi), 'Aepatic metabolism' (R. T. Williams), and 'Enzyme induction: causes and effects' (H. Remmer). Several of these papers will be published in Gut later. Abstracts of short papers given during the rest of the meeting follow.
