[Acute stomach lesions and changes in histamine level of various organs in immobilization stress].

In the glandular part of the stomach, the histamine content was significantly increased during stress by immobilization.

Although the maximum of stress ulcer formation did not correspond with the maximum increase in gastric histamine content as far as the time course is concerned, a role of histamine in stress ulcer disease cannot be excluded.
