Acid secretion, 1932-92: advances, adaptations, and paradoxes.
This paper reviews the evolution of our understanding of various aspects of gastric acid secretion over the past 60 years. Embryologic aspects and neonatal acid secretion are considered, and the relationship between parietal cell mass and acid secretion and the changing concepts of parietal cell activation are discussed. The effect of aging on acid secretion and the relevance of acid secretion in health and disease are reviewed, and current views on adaptation to therapeutic inhibition of acid secretion presented. The aetiologic link between acid secretion and ulcer disease is re-examined, and the role of pepsin, growth factors, and Helicobacter pylori briefly considered.
