Some aspects of the possible values of secretin in the formation will be discussed in the section on acid-peptic factor. It should be emphasized that direct evidence of participation of this hormone in the development of peptic ulcers is not. Recent studies Petersen (1969) with natural secretion found no impact of this hormone on the concentration of hydrochloric acid in the gastric juice. Along with this Berstad (1969) doubtless watched stimulus secretin on the pepsina.
Natural pork secretin prevented the formation of ulcers in cats in response to the introduction of pentagastrin (Konturek, 1968).
Thus, digestive hormones, obviously, are of great importance in the formation, however, many issues related to the mechanisms of their impact on the gastroduodenal system, still insufficiently developed.
