[Features of gastrin reaction in rats with different susceptibilities to gastric mucosa lesions in immobilization-cold stress].

The connection between the character of gastrin and acid reactions and visible morphological changes of gastric mucosa in immobilising-cold stress was studied in the experiments on mongrel rats. It is established that in the rats the fundal gastric mucosa is resistant to the disturbing action of the immobilising-cold stress. The post-stress gastrin contents in the antrum and duodenum mucosa is higher and in the serum lower than in rats with ulceration. The rats with the stress erosions have the intermediate position. The acid factor didn't play the significant role in the ulcerogenesis because its value didn't overstep the limits established in the extradigestive period.
