Abstract
The stomach wall ATP and ADP have been studied in rats, with and without bilateral surgical vagotomy, 24 hr after pylorus ligation. It was observed that the amounts and concentrations of ATP significantly decreased in both parts (corpus + antrum and forestomach) in pylorus-ligated rats, while the amounts and concentrations remained at a significantly higher level in pylorus-ligated+vagotomized rats. Changes in amounts and concentrations of ADP paralleled those of ATP. It has been concluded that a significant decrease of cellular ATP is necessary to produce gastric hypersecretion in ulceration in pylorus-ligated rats. This significant decrease of cellular ATP, in corpus + antrum and forestomach, can be prevented by bilateral surgical vagotomy.
