Examples from the Corpus
pepsinThe difference between mean rates of secretion of acid and pepsin in control subjects and patients with duodenal ulcer is about 190%.We found a relation between platelet activating factor precursors and acid, and between platelet activating factor precursors and pepsin.Peptic ulcers are produced by the self-destruction of the gut wall by pepsin and hydrochloric acid in gastric juice.This implies that the antibody is recognising an epitope that is cleaved by one of the digestive enzymes pepsin or trypsin.Gastric juice aliquots for pepsin measurement were centrifuged at 4°C.Increased histamine secretion was not, however, associated with increased acid or pepsin output at day 7.Yet we have confidently shown that the ulcer is not caused by hypersecretion of acid or pepsin.These studies therefore show that the ulcer formation is not due to hypersecretion of acid or pepsin.
