ABSTRACT
Objective To study the role of nitriergic nerves in the myenteric plexus of the gastric antrum in diabetic rats with motor disorder. Methods Rats were randomly divided into diabetic group and control group. Electrogastrogram was recorded, and the number of cholinergic nerves in the myenteric plexus of the gastric antrum was counted 3 months after reproducing diabetes in the model group. Results In the rats of diabetic group, gastro-electric dysrhythmia was observed more frequently, and the number of nitriergic cells in the myenteric nerves was significantly decreased compared with control group. Conclusion The changes in nitriergic nerves in the myenteric plexus of the gastric antrum might be one of the mechanisms of gastro-electric dysrhythmia and gastric motility disorders in diabetic rats.
