A novel enzyme immunoassay for serodiagnosis of Helicobacter pylori infection.

abstract：:Adenylate cyclase activity was measured in rat small intestinal villus and crypt cells after in vivo and in vitro exposure to cholera toxin. The increase in intestinal adenylate cyclase induced by cholera toxin in vivo appeared to be largely confined to the villus cell with the largest increase observed for upper vill...
