Gastric ulcer is a common digestive system disease with multiple causes and easy recurrence, which can occur in any age group. Stress gastric ulcer is an acute ulcer caused by dysfunction of the central nervous system and autonomic nervous system, leading to dysfunction of gastrointestinal motility and secretion function. The reserpine type gastric ulcer model and the anhydrous ethanol type experimental gastric ulcer model are commonly used to screen for anti gastric ulcer drugs. The morphology of the acetic acid induced gastric ulcer model in rats is similar to that of human gastric ulcers. The formation of ulcers is caused by the gradual erosion of the gastric wall by acetic acid, and can be used to observe the promoting effect of drugs on ulcer repair.
