Membrane-bound ATP-dependent Energy Systems, as Extra- and Intracellular Key Signals for Gastrointestinal Functions and their Regulations in the Gastrointestinal Mucosa

Aims: Our research group has carried out various biochemical examinations in rat gastric ulcer models and in human gastrointestinal resecates obtained from patient who underwent gastric intervention due to peptic ulcer disease. Biochemical methods gave excellent possibility to approach the biochemical events taking place in tissues, cellular and subcellular regulatory levels during of ulcer development and of its prevetions. This paper gives a brief summary of these biochemical examinations conducted during this study period started from the 1960' s up till now.
