[The self-regulation elements in the stomach secretor response to perturbing effects].
By the levels of stomach juice volume, its proteolytic activity, hydrogen ion activity, secreted mucus volume, the experimental dogs with stomach fistula were divided into two groups: with low and with high levels of secretion. The perturbing effects involved immobilization stress, mineral water, prolin-containing peptide Gly-Pro. One of the self-regulation mechanisms involved an "initial background rule": if the initial level of the secretion parameters is low, then it grows following the effect, whereas if it is high--it becomes lower. The rule was most evident in the stomach juice secretion complex-reflex phase.
