[Changes of somatostatin (SS) in stomach and duodenum of rats after +Gz exposure].

Objective: To study effects of +Gz exposure on the change of somatostatin (SS) in stomach and duodenum of rats.

Method: Forty male Wistar rats were randomly divided into +1 Gz control group, +5 Gz x 5 min group, +10 Gz x 5 min group and repeated exposure [(+5 Gz x 2 min) + (+10 Gz x 2 min) + (+5 Gz x 2 min)] group. After +Gz exposure, the rats in each group were anesthesized by aether, and gastric and duodenal mucosa were taken immediately.
